b. Hook up oscilloscope:
H Connect the oscilloscope probe to the CH1 vertical input.
H Connect the probe ground-clip to the GND pin of 2 × 13 header.

2. Create the AWG2021 waveform file, select 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. If Option 02 is installed (Option 02 adds the
CH2 output channel), Waveform Sequence toggles between the
CH1 files (upper list) and the CH2 files (lower list).
H Turn the general purpose knob to highlight the DIGI_OUT.WFM
file.
H Push ENTER to select the file.
c. Set AWG2021 controls:
H Push MODE!Cont
3. Check the CH1 digital data output signals:
a. Check the signal levels:
H Contact the oscilloscope probe to the pins on 2 × 13 header (see
Figure C-23). Check that the oscilloscope display shows these
signals:
Data signals D0-D11 and CLK (Clock) are TTL level output.
All other pins are ground.
