Appendix C: Performance Verification
2.Set the AWG2021 controls and select the waveform file:
a.Initialize AWG2021 controls: Push UTILITYMiscConfig...Re- set to FactoryO.K.
b.Select waveform file:
Push SETUPWaveform Sequence, if necessary, to select a waveform file for CH1. Waveform Sequence toggles between the CH1 files (upper list) and the CH2 files (lower list).
Turn the general purpose knob to select the PULSE.WFM file.
Push ENTER.
3.Turn on the AWG2021 CH1 output: Push the CH1 button so that the LED above the CH1 output connector is on.
4.Check pulse response at 0.5 V amplitude:
a.Check rise time: Check that the rise time of the waveform displayed on the oscilloscope from the 10% point to the 90% point is 4.2 ns or less.
b.Check aberrations: Check that the aberrations of the displayed waveform is within 0.45 div.
c.Check flatness: Check that the flatness of the displayed waveform is within 0.15 div. after 20 ns from the rising edge.
d.Change the oscilloscope controls:
Horizontal

e.Check fall time: Check that the fall time of the displayed waveform from the 10% point to the 90% point is 4.2 ns or less.
5.Check pulse response at 1 V amplitude:
a.Change the oscilloscope controls:

b.Change the AWG2021 controls:
Push SETUPAmpl to change the amplitude for CH1.
