2. Select the AWG2021 waveform file and set AWG2021 controls:
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 highlight the EXT_CLK.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 the external CLOCK IN threshold level:
a. Enable function generator output: Turn on function generator output.
b. Check the level: Check that the waveform displayed on the oscilloscope
has an amplitude of 5 divisions and a stable display of 5 cycles.
5. Turn off equipment output and disconnect test hookup:
a. Disable function generator output: Turn off function generator output.
b. Remove connections: Disconnect all connections to the AWG2021.
