Waveform Fundamentals
Scripts

You can link and loop multiple waveforms together in a generation operation using a script. A script is a series of instructions that indicates how waveforms saved in the onboard memory should be sent to the DUT. The script can specify the order in which the waveforms are generated, the number of times they are generated, and the triggers and markers associated with the generation.

You can create a script to manage waveform generation based on multiple waveforms and triggers. For example, you could download waveforms A, B, C, and D into device memory. You could then write a script that would wait for a trigger to initiate generation and, upon receiving this trigger, generate waveform A three times with a marker at position 16 each time and finally generate waveforms B, C, and D twice (BCDBCD). The following is the script of this example:

script myFirstScript
  wait until scriptTrigger0
  repeat 3
    generate waveformA marker0(16)
  end repeat
  repeat 2
    generate waveformB
    generate waveformC
    generate waveformD
  end repeat
end script
