Dual Arbitrary Waveform Generator Check Utility

(Option UND Only)

This check verifies the functionality of the dual arbitrary waveform generator. A triangular waveform is downloaded into the signal generator and then output to the rear-panel I and Q outputs. An oscilloscope is used to monitor the rear-panel I and Q outputs.

This test is not a performance test. This check is only provided to insure that the dual arbitrary waveform generator is operational. There are no specifications for this check.

Connections and Setup Procedures

Note

All test equipment requires a 30 minute warm-up period to ensure accurate performance.

In the following test setup, direct cable and adapter connections are designated as solid lines. Changeable cable and adapter connections are designated as dashed lines.

 

  1. Connect equipment as shown. The oscilloscope is not connected to GP-IB; this allows for the use of most general 2-channel oscilloscopes.

  2. Set the oscilloscope to display both Channel 1 and Channel 2. Set the oscilloscope to trigger on Channel 1.

  3. The recommended settings are:

 

  1. Verify that Channel 1 and Channel 2 are both displaying triangular waveforms approximately 180 degrees out of phase and that they do not have any discontinuities. Refer to the illustration below.
