Sweep Problems

Sweep Appears to be Stalled

The current status of the sweep is indicated as a shaded rectangle in the progress bar. You can observe the progress bar to determine if the sweep is progressing. If the sweep appears to have stalled, check the following:

❏Have you turned on the sweep by pressing any of the following key sequences?

Sweep/List > Sweep > Freq Sweep/List > Sweep > Ampl Sweep/List > Sweep > Freq & Ampl

❏Is the sweep in continuous mode? If the sweep is in single mode, be sure that you have pressed the Single Sweep softkey at least once since completion of the prior sweep. Try setting the mode to continuous to determine if the missing single sweep is blocking the sweep.

❏Is the signal generator receiving the appropriate sweep trigger? Try setting the

Sweep Trigger softkey to Free Run to determine if a missing sweep trigger is blocking the sweep.

❏ Is the signal generator receiving the appropriate point trigger? Try setting the Point Trigger softkey to Free Run to determine if a missing point trigger is blocking the sweep.

❏Is the dwell time appropriate? Try setting the dwell time to one second to determine if the dwell time was set to a value which was too slow or too fast for you to see.

❏Do you have at least two points in your step sweep or list sweep?

Cannot Turn Off Sweep Mode

Press Sweep/List > Sweep > Off.

In the sweep mode menu you can choose to set the sweep to various sweep types or to turn sweep off.

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.
