VX4792 User Manual
2. To set the VX4792 Arbitrary Waveform Generator controls and select the
waveform file, type:
3. Check clock amplitude accuracy: Check that the pulse displayed on the
oscilloscope has an amplitude between 0.7 V and 1.2 V
p-p
.
4. End procedure: Disconnect the oscilloscope.
Amplitude and Offset Accuracy Checks
These procedures check the accuracy of the output DC amplitude and offset
parameters.
. The amplitude and offset accuracy checks are structured as a continuous
test. After completing the Check DC Amplitude Accuracy test, you will use the
current control settings, and the next step in the sequence file, to perform the
Check Offset Accuracy test.
This procedure checks the DC amplitude accuracy.
Electrical Characteristic Checked: Main Outputs, Offset, DC Accuracy, on
page E–3.
Equipment Required: A 50 W coaxial cable, a BNC-to-dual banana adapter,
and a digital multimeter (DMM).
Prerequisites: The instrument must meet the prerequisites listed on page F–3.
Procedure:
1. Install test setup and set controls (see Figure F–14):
a. Connect DMM: Connect the WAVEFORM OUTPUT through a 50 W
coaxial cable, a 50 W terminator, and a BNC-to-dual banana adapter to
the DMM INPUT connector.
b. Set DMM controls:
