7008 Multi-channel Long Memory Digital Oscilloscope VIEW RECORDERS (70088) 6 5mm 7kg (6-3/ 8-3/ 6-3/" 37.5 lbs) Safety Standards; EN600 EMI Standard; EN550 Group Class A Immunity Standard; EN5008-: 995 The digital oscilloscope, with a maximum record length of 6 MW, features more than just a long record length. We designed this instrument to facilitate long record measurement work. This digital oscilloscope can efficiently capture abnormal phenomena buried in long data, allowing you to search for and analyze the causes of these abnormal phenomena. We made the record length per channel as long as possible to enable you to carry out efficient troubleshooting. We also designed the instrument to measure data in at least six channels, enabling you to determine the cause and effect relationship between each signal. The instrument also has excellent zoom operability to permit analysis of captured waveforms. Select the number of channels and record length suitable for your application. After the purchase, if you need more channels or a larger record length, your oscilloscope can be upgraded.

Dual zoom display The instrument supports a dual zoom display function which simultaneously displays the entire captured waveform together with two selected parts of the same waveform. History memory The history memory, which holds up to 8000 screens, can assist you in troubleshooting by letting you recall previous displays. Logic inputs (optional) logic probe offers 8 bit logic inputs in exchange for analog input. The feature provides mixed analog and digital signal observation. In its maximum configuration, the offers ch analog and 3 bit digital signal observation. Built-in 3.5 inch FDD Built-in MO drive (optional) Built-in printer (optional) FUNCTIONS EFFECTIVE UTILIZATION OF THE LONG MEMORY A long memory is useful not only for capturing single shot signals. The long memory of the can meet a variety of measurement needs. High Time Resolution Measurement Using the Long Memory When you need to capture fast noise and surge signals using a slow time/div range, a long record length is necessary. For instance, at 0 µs/div several tens of Kwords may be required. The MW record length of the supports a sampling rate of Record length Per channel M words M words M words M words Frequency band Number of channels that can be used at the max sampling rate or max record length 3 3 3
even when you are monitoring waveforms of several milliseconds. When you are observing transient phenomena or electronically controlled machine signals, the signals captured by the long memory are displayed on the screen in the correct orientation. Capturing Signals Using a Divided Long Memory History Memory Holds up to 8000 Past Images Troubleshooting of a designed circuit starts from capturing of an abnormal signal. Often, when you wish to capture an abnormal phenomenon, you do not know the correct trigger conditions for capturing the signal. You may be lucky enough to display the abnormal phenomenon on the screen by monitoring the signal for some time using simple trigger conditions. However, when you use a normal digital oscilloscope, an abnormal signal that appears momentarily is updated by the next signal. The history memory holds up to 8000 previous displays without any need for special settings. An abnormal phenomenon that appeared for only an instant can be recalled later. Example of a superimposed display of captured past screens Sequential Store Function with A Dead Time of 0 µs Normally, when a waveform is displayed on a digital oscilloscope in realtime, a dead time of several ms occurs. Consequently, you cannot use a normal digital oscilloscope for applications requiring acquisition of all the signals generated at intervals of ms or less. The sequential store function of the eliminates the process of displaying the acquired signals, thus enabling the signals to be captured with only a short dead time. Like the history memory function, the sequential store function enables signals that satisfy the trigger conditions for up to 8000 measurements to be acquired by the built-in memory. Difference between The History Memory Function and The Sequential Store Function Both the history memory function and the sequential store function use the memory divided into several blocks rather than as a single unit. The history memory function uses the divided memory blocks as a ring memory, and the contents of the oldest memory block are updated until the stop key is pressed. The sequential store function does not update the contents of the memory after acquiring the specified number of waveforms. As indicated in the figure below, when the sequential store function is used, signals are not displayed each time they are acquired into memory. History memory function: Effective for capturing abnormal signals whose nature is not known. Sequential store function: Effective for capturing signals generated at a rate of no more than several ms, without omission. Wave form display with sequential store-function Time Memory block of number of designations SIMPLE, VERSATILE ZOOM A zoom function that magnifies part of the captured signal is an important feature of a digital oscilloscope that has a long memory. The enables you to make various kinds of zoom displays by means of simple operations. Zoom that Can Simultaneously Display Traces with Intuitive Operations The zoom operation of the is the same as the popular zoom operation used in the DL50/D50L and DL000 series. The ASIC developed by YOKOGAWA processes the long memory at high speed, enabling you to display the desired area instantaneously. Various Zoom Displays The overall screen of a signal captured by the is defined as Main, and an enlarged screen of part of the waveform is defined as Zoom. You can set two enlarged areas Zoom (Z) and Zoom (Z) with respect to a captured waveform. You can combine the Main screen, the Z screen and the Z screen into a single screen. In the Main&Z&Z setting mode which simultaneously displays the Main screen and the two enlarged screens, Z and Z, a maximum of analog signals can be displayed simultaneously. Main display Main & Z & Z display By Using The Zoom Allocation Function, You Can Display An Enlarged Form of One or More of A Number of Waveforms on A Screen. When performing multi-channel measurements, if it is not necessary to enlarge all of the waveforms. You can use the zoom allocation function to display only certain selected waveforms in the Zoom screen in enlarged form.

VIEW RECORDERS YOU CAN SELECT A SIGNAL CAPTURING METHOD AND A DISPLAY METHOD THAT IS SUITABLE FOR THE PARTICULAR MEASUREMENT YOU WISH TO PERFORM. Envelope If you perform signal observation for at least several seconds, you cannot capture signals at the maximum sampling rate, even if you use a long memory of 6M words. However, by using the envelope mode of the, you can always store the peak value of the signal at a sampling rate of 00 MS/s, regardless of the Time/div setting. also be set using voltage values. You can use the measure save function. (which arranges the results of the past 5 measurements up to the point where signal acquisition stopped) to output these results in ASCII format. You can process these results using spreadsheet calculation software. Example of automatic measurement of waveform parameter When envelope is ON When envelope is OFF Box Average The resolution of the A/D converter of the is 8 bits. By using the box average function, you can capture signals at an equivalent resolution of up to bits depending upon the Time/ div setting. The box average function is also effective for capturing single shot signals. When box average is ON (After the signal is captured, zoom takes place in the voltage axis direction) When box average is OFF (After the signal is captured, zoom takes place in the voltage axis direction) Roll Mode Display The roll mode displays a low speed signal on the screen in such a way that it rolls, thus enabling it to be recorded on a pen recorder. This mode can also be used in combination with the envelope to capture surge signals of several tens of MHz, or in combination with the box average function to capture signals at high resolution. Histogram Analysis Wave statistical processing This function specifies the voltage and the time range. After a signal has been acquired a number of times, the frequency of occurrence of time values and voltage values are displayed. This is effective for analyzing jitter, for example. Statistical processing of the waveform parameter results The measurement results for the set number of acquisitions of the specified items of the waveform parameters are displayed in the form of a histogram. Voltage histogram display By displaying a histogram of voltage for each acquisition, you can analyze the waveform from a different angle. Waveform Calculation Software [User Define is An Option] The supports basic functions which performs addition, subtraction, multiplication and division phase performs a phase shift followed by before mentioned computations. Binary converts an analog signal into a bit patterns of ones and zeros, based on a defined threshold. User define math function (optional) enables you to combine various funtions to perform waveform calculation. Waveform display when the roll mode is used Example of roll mode display HIGH-SPEED PRIMARY PROCESSING OF CAPTURED SIGNALS The i960 Intel RISC processor installed in the automatically measures the waveform parameters, and also performs waveform calculations and other data processing, at high speed. Automatic Measurement of Waveform Parameters You can select various items such as amplitude, rise, and interchannel delay, from a total of items, for each channel. The reference values of the parameters related to the time axis can Example of a user define of the
The user define math function offers functions such as square root, exponential, common logarithms, differentiation, and integration, pulse-width, Hilbert transform, and FFT. These calculations are all performed in the Math and Math areas and you can also use calculation results from Math in Math functions. By combining these functions, you can perform calculations such as demodulation of FM modulated waveforms. Linear Scaling Function Converts Voltages into Physical Values. When recording an output from a sensor, for example, it is desirable to convert it directly into a physical value such as rpm or m/s rather than leaving it as a voltage. The linear scaling function of the assigns coefficients and offset values to enable the input voltage to be converted into a physical value. In addition, a unit can be attached to a converted result, enabling it to be displayed directly as a physical value. YOU CAN OUTPUT A CAPTURED WAVEFORM IN VARIOUS FORMS DEPENDING ON THE PARTICULAR APPLICATION. Outputting A Signal to The Built-in Printer (option) There are two ways you can output a signal to the built-in printer. The short copy format in which the screen data is printed and the long copy format in which signal data in the acquisition memory is printed out in an expanded form. Example of short copy Example of long copy TRIGGERS THAT ARE SUPPORTED BY THE Trigger functions for ease of operation Select one of two trigger settings, SIMPLE which is related to edge trigger settings, and ENHANCED which is related to other settings, according to your particular application. SIMPLE Settings related to the edge trigger Edge trigger Gate trigger A trigger is generated when the selected waveform crosses a set level. A vertial gate is placed ahead of the trigger point. A trigger occurs when the trigger conditions are met after the signal meets the gate condition(pass or bypass) A B (n) A Delay B Edge On A The trigger condition is satisfied when the B trigger occurs n times after the A trigger condition is met. The trigger condition is satisfied when the B trigger conditions are met after the A trigger occures and the set delay time has elapsed. The trigger occurs at the point in time at which the edge of a selected input channel is detected while the A pattern trigger condition exists. OR The trigger occurs when any one of the individual channnel edge triggers occur. ENHANCED Settings not related to the edge trigger B > Time B < Time A trigger is generated on the falling or rising edge of a pulse when the pulse width exceeds the preset time. The setable range is 90ns to 5s. A trigger is generated on the falling or rising edge of a pulse when the pulse width is less than the preset time. The minimum glitch detection is 5ns. B Time Out A trigger occurs when the B trigger condition remains true for the set period of time. TV Window Logic A trigger is generated by a video signal such as NTSC, PAL, HDTV, etc. A trigger occurs when the signal crosses the upper or lower defined levels. A trigger is defined by combination of the logic inputs.
