Troubleshooting

Sweep Problems

Incorrect List Sweep Dwell Time

If the signal generator does not dwell for the correct period of time at each sweep list point, follow these steps:

1.Press Sweep/List > Configure List Sweep. This displays the sweep list values.

2.Check the sweep list dwell values for accuracy.

3.Edit the dwell values if they are incorrect.

NOTE

The effective dwell time at the RF OUTPUT connector is the sum of the value set for the

 

dwell plus processing time, switching time, and settling time. This additional time added to

 

the dwell is generally a few milliseconds. The TTL/CMOS output available at the

 

TRIG OUT connector, however, is asserted high only during the actual dwell time.

 

 

If the list dwell values are correct, continue to the next step.

4.Observe if the Dwell Type List Step softkey is set to Step.

When Step is selected, the signal generator will sweep the list points using the dwell time set for step sweep rather than the sweep list dwell values.

To view the step sweep dwell time, follow these steps:

a.Press Configure Step Sweep.

b.Observe the value set for the Step Dwell softkey.

List Sweep Information is Missing from a Recalled Register

List sweep information is not stored as part of the instrument state in an instrument state register. Only the current list sweep is available to the signal generator. List sweep data can be stored in the instrument catalog. For instructions, see “Storing Files to the Memory Catalog” on page 53.
