2. Set the AWG2021 controls and select the waveform file:
a. Initialize AWG2021 controls: Push UTILITY!Misc!Config...!Re-
set to Factory!O.K.
b. Select waveform file:
H Push SETUP!Waveform 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).
H Turn the general purpose knob to select the PULSE.WFM file.
H 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:

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:
