Check Internal AM Operation
Electrical Characteristic Checked: Arithmetic Operation, Amplitude
Modulation, on pageĂ1Ć13.
Equipment Required: Two 50ĂΩ coaxial cables, a function generator, and
a digital multimeter (DMM).
Prerequisites: The AWG2005 meets the prerequisites listed on page 4Ć7.
Procedure:
1. Use test hookup and control settings from previous check.
2. Check internal AM operation:
a. Check Autostep Step 2:
H Push the AWG2005 MANUAL TRIGGER button, and check that
the step changes to Step 2 on the MODE menu.
H Check that the DMM reading is in the range from 2.375Ăto
2.625ĂVDC.
b. Check Autostep Step 3:
H Push the AWG2005 MANUAL TRIGGER button, and check that
the Autostep changes to Step 3 on the MODE menu.
H Check that the DMM reading is in the range from -2.625Ăto
-2.375ĂV.
3. End procedure: Retain the test hookup and settings for the next check.
