Arithmetic Operation Checks

Check External AM
Operation
AWG2021 Service Manual
These procedures check operation of external AM. For an AWG2021 with
Option 02, the procedures check internal AM and internal ADD arithmetic
functions.
NOTE. The arithmetic operation checks are structured as a continuous series of
tests. After Check External AM Operation, each test uses the control settings
from the last test, and the next step in the sequence file.

Characteristic
Checked
Equipment Two 50 W coaxial cables
Required
One 50 W terminator
One function generator
One digital multimeter (DMM)
Prerequisites The AWG2021 meets the prerequisites listed on page 4-7.
1. Install test hookup and set test equipment controls:
a. Hook up DMM: Connect the AWG2021 CH1 output through a coaxial
cable, the 50 W terminator, and BNC-to-dual banana connector to the
DMM INPUT connector.
b. Hook up function generator: Connect the AWG2021 rear-panel AM IN
input through a coaxial cable to the function generator output (see
Figure 4–10).
