Measuring a Waveform

    Last Modified: May 14, 2018

    This example illustrates how to use the Function and Arbitrary Waveform Generator (FGen/Arb) to generate a waveform and use the Oscilloscope to measure the waveform.

    The procedure for measuring other types of waveforms is similar. Refer to the Configuration Options (Oscilloscope) section to learn about other functionalities of the Oscilloscope.

    1. Connect a BNC - BNC cable between Oscilloscope CH 1 and Function Generator CH1 on the NI ELVIS III, as shown in the following diagram:

      Refer to Connecting Signals to the Oscilloscope for more details about connecting to the Oscilloscope.
    2. Launch the FGen/Arb Soft Front Panel (SFP).
    3. Configure the FGen/Arb to generate a sine wave on Channel 1.
    4. Click Run to start generating a sine wave.
    5. Launch the Oscilloscope Soft Front Panel (SFP).
    6. Configure the Oscilloscope to measure the input signal on Channel 1.
    7. Click Run to start measuring the input signal. A sine wave appears in the display window.
    8. Adjust the display settings as needed. You can also select Automatic Setup if you want the Oscilloscope to choose some settings automatically.
    9. If necessary, adjust the trigger settings to stabilize the waveform in the display window.

    You may hear clicking sounds from the NI ELVIS III while operating the SFP. This is expected behavior and is due to the switching of internal relays.
