4 Abstract Adding and Removing Instruments 1 Abstract Forum is a free scripting tool developed by noriba GmbH for remote control of Rohde & Schwarz instruments. It allows users to run and edit example script sequences and to write their own script files, as well as on-the-fly remote control of the instrument. Script files can range from simple command sequences (Winbatch syntax) to complex programs using the programming language Python. The Forum application uses the VISA interface, which allows remote control of instruments via LAN, GPIB, USB, etc. 2 Installation The Forum application must be installed on the PC. This application note comes with an installer, which includes: The Forum application A Python interpreter The Forum application uses the VISA interface, which is not included in the installer. The National Instruments VISA, available on the National Instruments homepage ( is recommended. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 4

5 Instrument Configuration Adding and Removing Instruments 3 Instrument Configuration Before an instrument can be addressed, it must be added to the Instruments Configuration. After starting the Forum application, choose Edit > Instrument Configuration. This will bring up the Instruments Configuration screen. This screen shows a List of devices that lists all previously configured instruments. The Enabled column contains either a green checkmark or a red X for each instrument. Click a checkmark to change it to an X and vice versa, thereby disabling or enabling the use of this instrument. Every time the List of devices is reloaded, the Forum application will try to establish a connection to all enabled instruments and then indicate whether the connection is active in the Connection column. You can speed up this process by disabling all the instruments known to be switched off or not connected. An instrument will be accessible in scripts only if it is enabled and its Connection column shows active. Fig. 1: The Instruments Configuration screen. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 5

6 Instrument Configuration Adding and Removing Instruments Alternatively, you can add an instrument for just one session by using the Instrument drop-down menu in the vertical Control Panel on the left (see Fig. 2). Just open the drop-down menu and choose <new>. Fig. 2: The Instrument drop-down menu. This will open up the Instrument Connection Configuration window. Instruments added through this dialog are not saved and will no longer be available after you close and then restart the Forum application. 3.1 Adding and Removing Instruments The Instruments Configuration screen includes a list of instruments. Click any of the list entries to edit the instrument s configuration, including VISA connection type, host name or timeout. Click the Insert button to add a new, empty list entry. This new entry will automatically be selected to allow editing. Fig. 3: Editing VISA settings. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 6

7 Instrument Configuration Adding and Removing Instruments The following settings can be configured: The Interface Type is the type of the connection The Device Name is the name that will be used in scripts to identify the instrument The termination chars can be left blank to use the default setting The timeout is the time in seconds that the Forum application waits for a response from an instrument before showing a timeout error The delay is the time in milliseconds to wait after each write command sent to the instrument The other settings on the left-hand side are specific to the selected Interface Type and serve to configure the connection. They will be addressed separately in the following subsections The settings on the right-hand side are VISA attributes that should be configured by advanced users only. For more information on these attributes, please consult the VISA documentation In the Instrument Connection Configuration window (opened by clicking <new> in the vertical Control Panel), the following attributes can be changed: The Alias equals the Device Name on the Instruments Configuration screen The Device Type equals the Interface Type The Number is used in the case of multiple adapters on the PC and can be 0 in most cases Timeout and Delay correspond to the attributes of the same name on the Instruments Configuration screen The Identifier (IP or Hostname) is specific for the selected Device Type and will be addressed separately in the following subsections Advanced users who are familiar with VISA address strings can directly edit the VISA RSC field Click the Test Connection button to check if a connection works correctly. Fig. 4: The Instrument Connection Configuration window. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 7

8 Instrument Configuration Adding and Removing Instruments VXI LAN Interface (TCPIP_VXI_11) To address an instrument connected by LAN, you should usually choose Interface/Device Type TCPIP_VXI_11. You can configure the following attributes for this option: Instruments Configuration screen: The host name can be the instrument s network device name or the IP address. The identity is not mandatory unless there is more than one VISA entity running on the same instrument. In this case, inst0 would be the first VISA entity, inst1 the second, etc. Instrument Connection Configuration window: The Identifier equals the host name and can be network device name or IP address. The Identity, like above, is not mandatory unless there is more than one VISA entity running on the same instrument. In this case, inst0 would be the first VISA entity, inst1 the second, etc HiSLIP Interface (TCPIP_HISLIP) Some instruments can be used with the new IVI HiSLIP (High Speed LAN Instrument Protocol). To see if your instrument supports this protocol, please check the instrument manual. If you want to use this connection variant, choose Interface/Device Type TCPIP_HISLIP. Instruments Configuration screen: The host name can be the instrument s network device name or the IP address, similar to the VXI LAN Interface. The identity is important this time to identify the HiSLIP connection type. Use hislip0 if there is only one VISA entity running on the instrument. If there are multiple VISA entities, hislip0 would be the first, hislip1 the second, etc. Instrument Connection Configuration window: The Identifier again equals the host name and can be the network device name or IP address. The Identity must start with hislip to identify the HiSLIP connection type. If there are multiple VISA entities running on the instrument, the first one is identified by Identity hislip0, the second one is hislip1 etc. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 8

9 Instrument Configuration Adding and Removing Instruments LAN Socket Interface (TCPIP_SOCKET) Generally, you should use the VXI LAN interface to configure a connection via LAN. But in some cases you might want to configure the connection more directly. For these situations, you can use socket communication, also known as Raw Ethernet communication. Choose Interface/Device Type TCPIP_SOCKET for this connection variant. Instruments Configuration screen: Like with the TCPIP_VXI_11 Interface Type, the host name can be the network device name or the IP address of the instrument. The port number is the number of the network port on the instrument that you are connecting to. It usually is 5050 or Instrument Connection Configuration window: Like with the TCPIP_VXI_11 Device Type and above, the Identifier can be the network device name or the IP address of the instrument. The Identity is the port number to be used, usually 5050 or Note: This configuration lacks some important trigger functions. It is recommended that you use the VXI LAN interface instead General Purpose Interface Bus (GPIB) To configure a GPIB connection, choose Interface/Device Type GPIB. Instruments Configuration screen: Configure the primary address of the instrument. A secondary address can also be specified, for example when configuring a Rohde & Schwarz CMU. Instrument Connection Configuration window: Enter the primary GPIB address as Identifier. If you wish to configure a secondary address, add it to the Identifier after the primary address, separated by two colons ::. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 9

10 Instrument Configuration Adding and Removing Instruments R&S NRP-Z USB Connection (RSNRP) To control R&S NRP-Z sensors from a PC, install the NRP Toolkit, which is supplied with any R&S NRP-Z sensor and can also be downloaded from the Rohde & Schwarz homepage. You also need the R&S NRP-NI-VISA Passport, which can also be found on the Rohde & Schwarz homepage ( After connecting the R&S NRP-Z sensor to your PC, run VISA interactive control (from the Start menu: Programs > National Instruments > VISA > VISA Interactive Control ). It will list all currently connected instruments (see Fig. 5). There you will find a VISA address string in the syntax: RSNRP::<model code>::<serial number>::instr. Fig. 5: R&S NRP sensor in VISA Interactive Control. Instruments Configuration screen: Insert the model code and serial number into the respective fields. Instrument Connection Configuration window: For the connection to work, the VISA RSC field must contain the same string as is displayed in VISA Interactive Control; therefore, specify <model code>::<serial number> as Identifier. The Identity field will be ignored. Edit the VISA RSC field manually to remove the 0 from RSNRP0. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 10

11 Instrument Configuration Adding and Removing Instruments USBTMC Interface (USB) Note: To connect an R&S NRP sensor, you need to use the RSNRP connection interface (see section R&S NRP-Z USB Connection). To connect an instrument via USB Test and Measurement Class (USBTMC), you need to know the vendor id (VID), product id (PID) and serial number. If you have NI VISA installed, it will automatically detect the instrument after the instrument has been connected to the computer via USB. To get the required parameters, run VISA Interactive Control (from the Start menu: Programs > National Instruments > VISA > VISA Interactive Control ). This program will list all currently connected instruments (see Fig. 6). There you will find a VISA address string in the syntax: USB0::<vendor id>::<product id>::<serial number>::instr. Fig. 6: USB instrument in VISA Interactive Control. The vendor ID for Rohde & Schwarz instruments is 0x0AAD. Instruments Configuration screen: Enter the vendor id (VID), product id (PID) and serial number into the respective fields. Instrument Connection Configuration window: For the connection to work, the VISA RSC field must contain the same string as is displayed in VISA Interactive Control; therefore, specify <vendor id>::<product id>::<serial number> as Identifier. The Identity field will be ignored. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 11

12 Instrument Configuration Adding and Removing Instruments Serial Port (ASRL) To control an instrument via the serial port, choose Interface Type ASRL. There you have to configure the resource name (COM1, COM2 etc), the baud rate, number of data bits, number of stop bits and the parity check method to use. You cannot configure a serial connection in the Instrument Connection Configuration window Telnet Interface (TELNET) Unlike the other interfaces, the Interface Type Telnet does not use the VISA interface. Instead, it establishes a simple TCP connection. Its configuration uses the same parameters as those described in section LAN Socket interface, but the VISA attributes will not be available. You cannot configure a telnet connection in the Instrument Connection Configuration window. Note: This configuration lacks some important trigger functions. It is recommended that you use the VXI LAN interface instead. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 12

13 Instrument Configuration Adding and Removing Instruments Configuration Example As an example, we will configure an R&S SMU200A signal generator connected via LAN. The instrument s hostname is RSSMU200A You can usually look up your instrument s host name on your instrument in the Setup subsection; for more information consult the instrument manual. Choose Edit > Instrument Configuration, then click the Insert button. Assign the parameters values as follows: Fig. 7: Example instrument. As Interface Type, choose TCPIP_VXI_11. This means the instrument is connected via LAN. As Device Name, type SMx. That is the name you will use in the scripts to address this instrument. As host name, type the network device name of the instrument; e.g. RSSMU200A in this example. Keep the default settings for all the other values. You rarely need to change these. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 13

14 Instrument Configuration Export and Import Instrument Configuration Click the Save & Reload button. If you configured your instrument correctly (and it is connected and running), you should see a new entry in the List of devices table, with the VISA address string as Resource Name and active as Connection (see Fig. 8). Fig. 8: Working instrument. 3.2 Export and Import Instrument Configuration You can export your instrument configuration on the Instruments Configuration screen by clicking the Export button. You are then prompted by a dialog to save the configuration to a file. An exported instrument configuration can be imported again by clicking the Import button and choosing a previously exported file. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 14

15 User Interface Export and Import Instrument Configuration 4 User Interface If you start Forum using the link in the Start menu or from your desktop, you will see only the Communicator tab. Another tab, called the Reporter, is also available. For a brief description of the Reporter and how to reach it, refer to section Reporter. Fig. 9: The Communicator. The Communicator is divided into several sections: The Shell (1) The commands editor (2) The Explorer (3) The Protocol Trace (4) The macro buttons (5) Some configuration options (6) The Namespace tab and the Logging Trace are for advanced users only. The Logging Trace shows errors and debug information for all Forum actions, and the Namespace tab allows browsing of all objects available in scripts and the shell in expandable tree form. For more information, refer to the Forum documentation (see 6 References). 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 15

16 User Interface The Shell 4.1 The Shell The Forum application provides you with an interactive Shell to quickly and directly communicate with connected instruments. Fig. 10: The Shell. Any command or line of code written in the Shell will be immediately executed. To write a script of multiple lines before executing the lines, use the commands editor. For a description of the commands used to control the connected instruments, refer to section 5 Remote Control. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 16

17 User Interface The Commands Editor 4.2 The Commands Editor The commands editor allows you to create new scripts or modify existing ones. All scripts supplied by Rohde & Schwarz will be displayed here after they are opened. To run a script, it must first be opened in this section. The supplied operations New, Load, Save, Save as, Undo and Redo all work in the commands editor. The script files are standard text files (ASCII / UTF-8) and can have any extension, although the extension i3e is recommended for ease of recognition. Fig. 11: The commands editor. The Commands editor behaves like a programming environment. You can type your code here and run it using either the Run button on the left or the corresponding icon at the top of the control panel. The entire script is run when you click Run. If you want to run small fragments, simply double-click a line of code. This line will then be executed in the Shell. Because the Shell and the commands editor share the same namespace, all variables defined in the commands editor will also be available in the Shell and vice versa. For a description of the commands used to control the connected instruments, refer to section 5 Remote Control. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 17

18 User Interface The Explorer 4.3 The Explorer The Explorer is designed for the management of multiple test scripts. It uses a familiar tree structure to display directories and files of specified types. Fig. 12: The Explorer. To use the Explorer effectively, you should define a directory where all Rohde & Schwarz test scripts will be saved, with a separate folder for every Rohde & Schwarz application note. You can then extract the test scripts into the appropriate folder. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 18

19 User Interface The Protocol Trace 4.4 The Protocol Trace The Protocol Trace displays any commands sent to instruments via a running test script, as well as the responses from the instrument. It also shows timestamps and, in case of a query, the length of time the instrument took to send a response. Fig. 13: The Protocol Trace screen. The Protocol Trace is influenced by the settings described in section 4.6 Configuration Options. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 19

20 User Interface The Macro Buttons 4.5 The Macro Buttons When working with instruments, it can be useful to assign frequently used commands to the macro buttons (e.g. *IDN? ) to quickly test whether the instrument is still responding. This is done using the macro buttons feature. The macro buttons are located in the vertical Control Panel on the left. Fig. 14: The macro buttons. In addition to the supplied buttons, you can configure your own macros by clicking the Macro Setup button. Fig. 15: Macro setup. Here you can add, remove and rename macros. Each macro in the list on the left will be a button in the main window. Click a macro in the list to view and edit its code. The code works the same way as in the Shell and the commands editor (see section 5 Remote Control), but you can additionally use the pseudo-variable _device to address the instrument selected in the drop-down menu above the macro buttons. You should always use this identifier rather than actual device names to keep your macros abstract and reusable. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 20

21 User Interface Configuration Options 4.6 Configuration Options These options influence the arrangement of the window components and the logging behavior. They can be found on the vertical Control Panel on the left. Fig. 16: Configuration options. Four Logging Type options are available: none: The SCPI commands that are sent and received will not be logged or displayed screen: The SCPI commands will be displayed in the Protocol Trace section but will not be saved file: The SCPI commands will be saved to a file. The filename is the same as the script file, with an added sequential number in square brackets and the extension ptc. The commands will not be displayed in the Protocol Trace both: The commands will be both displayed and saved to a file Use Max Screen Lines to define the maximum number of lines displayed in the Protocol Trace before old lines will be dropped. Use the Window Split option to configure whether the Protocol Trace will be displayed below the Shell/Explorer or at the right side of the window. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 21

22 Remote Control Direct Commands (Winbatch Syntax) 5 Remote Control Forum features two methods of controlling your instruments: either direct commands or the Python method. 5.1 Direct Commands (Winbatch Syntax) If you just want to send SCPI commands, the easiest way is by using direct commands. To send a direct command, just type the Device Name (as configured during instrument configuration), a colon ( : ), one or more spaces ( ) and the SCPI command. Example: SMx: *IDN? Fig. 17: Direct commands in the Shell. This script syntax provides backward compatibility to the Winbatch script interpreter. Winbatch files can be opened and run by the Forum application without any adjustments. This method allows quick sequences of commands, but no variables or programming syntax. 5.2 Python Forum is based on the programming language Python and allows the Python language to be used when writing remote control scripts. All active instruments exist in the shell s namespace as objects of a class VisaDevice that is named by the Device Name configured during instrument configuration. The most important members of this class are: write: This method sends a string, usually a SCPI command, to the instrument. Example: SMx.write("*RST") 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 22

23 Remote Control Python ask: This method sends a string and then requests a response from the instrument. This response is returned and can be stored into a variable. Example: id = SMx.ask("*IDN?") Fig. 18: Python object representing VISA instrument. For more advanced interaction with the instrument, you can use the VisaDevice s member instrument, which supplies many useful methods such as read_floats (which returns the read output as a list of float values). Programming constructs such as if-clauses, loops or variables are also available. A brief introduction into the most common constructs will be given in the following subsections, presupposing basic programming experience. For more information on Python and Forum classes, please refer to the online documentation at as well as the Forum documentation (see section 6 References). A small example script is additionally provided in the Appendix (8.1 Example Script) Variables In Python, you declare a variable simply by assigning a value to it. Example: print a #Produces an error, a does not exist a = 1 print a #Works The variable type is assigned automatically and can be changed at any time by assigning data of a new type. Example: a = 1 #int a = "1" #string a = '1' #string, equivalent to "1" 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 23

24 Remote Control Python An important type is the list, because it is the main return type whenever you query information from an instrument. Example: a = FSx.ask("TRAC:DATA? TRACE1") #get trace from fsq b = a[0] #get first element c = len(a) #get the length of the list a.append("new entry") #add an entry to the end Even single return values queried by the member ask will be in a list, containing only one string value. Example: a = SMx.ask("SOUR:FREQ?") #a is now a List b = a[0] #b is now a single string To create a float value from a string, use the function float. To create an int value, use int. Example: a = int("12") b = float("12") To change a numerical value back to a string, use the function str. Example: a = 500 SMx.write("SOUR:FREQ " + str(a) + " MHz") Alternatively: SMx.write("SOUR:FREQ %d MHz" %a) If-Clauses This is what a typical Python if-clause looks like: if a == 1 and b >= 2: print "a == 1" print "and b >= 2" print "always visible" As you can see, the two lines after the if are indented. In Python, all following lines with the same indention belong to the same code block. The two lines after the if will be executed only if the condition is met, while the third line, which is not indented, will always be executed. For the condition, Python supplies the logical operators and, or and not, and the logical values True and False. Brackets can be used as well. An if-clause can also have an else statement, of course. Example: if a == 1: print "a == 1" else: print "a!= 1" 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 24

25 Remote Control Python An elif statement is also available. Example: a = SMx.ask("SOUR:FREQ?") a = float(a[0]) if a == : print "Frequency: 1 GHz" elif a == : print "Frequency: 2 GHz" elif a > : print "Frequency > 2 GHz" else: print "Frequency unknown" #Change format from List containing #a string to a float When you write an if-clause in the Shell (see section 4.1 The Shell), execution will be postponed while you are still writing lines belonging to the if-clause. As soon as you write an empty line, the if-clause is considered to be complete and is executed as a whole Loops The syntax of loops is similar to if-clauses. The first line ends with a colon :, and the following lines are indented. Example (while-loop): while a < 10: a += 1 The for-loop consecutively assigns the components of a list to a variable. Example: a = [1, 2, 3, 5] for x in a: print x To create a classic for-loop that runs through numeric values in a defined step, you can use the range function, which returns a list of numeric values. If range is used with one argument, it generates a list with values from 0 to the argument minus 1, with a step size of 1. Example: a = range(10) # a is now [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] Two arguments define the starting value and the end value. Example: a = range(5,10) # a is now [5, 6, 7, 8, 9] 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 25

26 Remote Control Python When using three arguments, the last one is the step size (which can also be negative). Example: a = range(5,10,2) # a is now [5, 7, 9] Therefore, if you want to change the frequency of an R&S SMU200A to values from 100 MHz to 200 MHz in steps of 2 MHz, the notation would be: for i in range(100, 201, 2): print i SMx.write("SOUR:FREQ " + str(i) + " MHz") As with the if-clauses, writing a loop in the Shell will postpone its execution until all the lines of the loop have been written, which is indicated by an empty line. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 26

It includes features that are not relevant or even necessary for typical use cases. But for the sake of completeness they will be mentioned here SOAP Configuration The Forum application allows remote procedure calls to compatible services using the established standard SOAP. This allows test scripts to use centralized services such as databases. The R&S CMW500 protocol tester also features a SOAP interface. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 28

29 Appendix Additional Features To configure a remote SOAP service, choose Edit > SOAP Configuration. This will open the SOAP Devices Configuration screen, which works similarly to the Instruments Configuration screen (see section 3 Instrument Configuration). Fig. 19: SOAP Devices Configuration screen. The following SOAP service parameters can be configured: The Device Name is the name used in scripts to identify the instrument The location is the IP address or the host name of the remote server where the service is located port is the remote network port service name is the name of the service target is the location path of the service on the server timeout is the time (in seconds) that the Forum application waits for a response from the SOAP server before aborting Debug Run The Debug Run feature allows users to debug scripts in a programming environment. This feature requires an external tool created by Nir Aides called WinPdb, GNU General Public License Version 2 or later ( The debugger is part of the Forum distribution. 1MA196_1e Rohde & Schwarz Using the Forum Application for Remote Control 29
