1 7050/7050/70505/7055 Digital Oscilloscopes DL540/DL540L/DL50/DL50L FUNCTIONS SIGL OBSERVATION USING LONG MEMORY Capturing Signals Using Long Memory for Accurate Waveforms The DL50/DL540 can continuously capture signals using a record length of up to 0k words, and the DL540L/DL50L using a record length of up to 00k words. Within the desired observation period, the DL50/DL540 can thus capture signals at a time resolution (sampling rate) of 0 times that for signals captured using a record length of k word, and the DL540L/DL50L at a time resolution of 00 times. (You can use a longer record length when capturing a single-shot signal, or when using the roll mode.)

The DL500 series inherits the popular intuitive, high-speed zooming function of the DL4000 series. The DL500 series eliminates problem of which trace to assign the zoom trace to. This scope allows you to display the captured trace and the zoomed trace at the same time. DL500 SERIES Basic Specifications Interface Functions Number of input channels Max.

2 DL540/DL540L/DL50/DL50L Recall Any Waveform with The History Memory Function (DL540/DL540L/DL50L only) With a conventional digital oscilloscope, the contents of the memory are updated at every trigger. So once a waveform is updated, there is no way to bring the previous waveform back. However, the history memory function of the DL540/ DL540L/DL50L stores the last 00 displays. A SINGLE OSCILLOSCOPE TO PERFORM EVERYTHING, FROM PROCESSING TO RECORDING OF THE CAPTURED SIGL (al built-in printer is needed to print captured waveforms) Automatic Waveform Parameter Measurement Function With this function you can automatically measure the maximum voltage, frequency and other parameters of a waveform. Roll Mode for Maximum Sampling Speed of 00 ks/s Roll mode is ideal for observing low frequency signals of around 0 Hz, which is difficult to do with a conventional analog oscilloscope. The roll mode allows a maximum sampling speed of 0 ks/s for the DL50/DL540, or 00 ks/s for the DL540L/DL50L. Compiling a Report Using a Hard Copy/Image File By using the built-in 3.5-inch FDD that supports three MS-DOS modes, you can save waveform data, panel setting information and hard copy images from the screen. You then simply import the hard copy of the screen directly into a word processor document when writing a report or paper using a PC with Windows. Screen Update Speed Independent of Number of Traces Displayed or Waveform Processing Type As shown in the figure below, it is easy to overlook an irregular event if the digital oscilloscope has a slow screen update speed. With most digital oscilloscopes, the screen update speed falls as the number of waveforms displayed is increased, or when signal processing such as automatic measurement of the waveform parameters is taking place. The DL500 Series has been designed primarily for measuring waveforms; hence signals are measured without reducing the screen update speed even when the number of waveforms displayed is increased or signal processing is added. Actual signal Real-time Printing Function Captures 0 ns Pulse Signals The real-time printing function continuously records low-speed signals to the built-in thermal printer. The chart speed runs at up to 6.7 mm/s, and the speed can be changed by setting the time axis.

3 DL540/DL540L/DL50/DL50L Short Copy Function Outputs a Screen Hard Copy in Just 0 Seconds This function outputs a hard copy of a waveform displayed on the screen to the built-in printer. You can even attach to the screen hard copy the panel setting information that was used to capture the waveform. OR Trigger ( for DL540/DL540L Only) A trigger occurs when any one of the trigger conditions which are set for each channel is satisfied. Long Copy Function Records Signals in Expanded Form after Storing Them in Long Memory With the long copy function of the DL500 Series, you can print out signals in expanded form after first storing them in the memory. When using the zoom function, an expanded screen can only be displayed one page at a time on the CRT. By using the Long Copy function, you can print an expanded diagram containing many pages of the expanded waveforms. A WEALTH OF TRIGGER FUNCTIONS Window Trigger A trigger occurs when the incoming signal crosses one of the upper or lower level thresholds which you set in advance. So you can capture signals even if you don t know the polarity of the noise component on the DC line. Pulse Width Trigger, Timeout ( for DL540/DL540L Only) A trigger occurs when the pulse width becomes narrower or wider than the defined width. In the case of the timeout trigger, a trigger occurs when the next signal is not detected within a certain time. Trigger point TV Trigger You can apply a trigger to NTSC, PAL and HDTV signals and specify the number of lines of the signal to be captured. (The HDTV trigger is supported only by the DL540/DL540L.) Pattern Trigger ( for DL540/DL540L Only) By assigning High, Low, or Don t Care to each channel, you can trigger on a combination of signals. You can also assign the signal in one channel as the trigger source.
