b. Change the AWG2021 controls:
H Push MODE!Polarity to highlight Negative.
H Select Level from the side menu, and turn the general purpose knob
to select –1 V. (You can also use the numeric and units keys to select
–1 V; then push ENTER.)
c. Check external trigger level accuracy:
H Gradually decrement the function generator offset level until a
waveform is displayed on the oscilloscope.
H Check that that the function generator offset level is from –1.15 V to
–0.85 V, when the waveform is first displayed.
6. End procedure: Turn off the function generator output and disconnect the
function generator.
External CLOCK IN Check
This procedure checks the AWG2021 response to an external CLOCK IN signal.

Characteristic Checked
Auxiliary Inputs, Clock, Threshold level, on pageĂBĆ9.
Equipment Required Two 50ĂW coaxial cables, a function generator, and an
oscilloscope.
Prerequisites The AWG2021 meets the prerequisites listed on page CĆ5.
1. Install test hookup and set test equipment controls:
a. Hook up oscilloscope: Connect the AWG2021 CH1 output through a
coaxial cable to the oscilloscope CH1 vertical input.
b. Hook up function generator: Connect the AWG2021 rear-panel CLOCK
IN through a coaxial cable and SMA-BNC adapter to the function
generator output (see Figure C-19).
