Troubleshooting
Sweep
Sweep
Cannot Turn Off Sweep
Press Sweep > Sweep > Off.
Sweep Appears Stalled
The current status of the sweep is indicated as a shaded rectangle in the progress bar (see
“Configuring a Swept Output” on page 48). If the sweep appears to stall, check the following:
1. Turn on the sweep with one of the following key sequences:
Sweep > Sweep > Freq
Sweep > Sweep > Amptd
Sweep > Sweep > Waveform (vector instruments only)
2. If the sweep is in single mode, press the Single Sweep softkey.
3. If the sweep trigger (indicated by the Sweep Trigger softkey) is not set to Free Run, set it to Free
Run to determine if a missing sweep trigger is blocking the sweep.
4. If the point trigger (indicated by the Point Trigger softkey) is not set to Free Run, set it to Free
Run to determine if a missing point trigger is blocking the sweep.
5. Set the dwell time to one second to determine if the dwell time was set to a value that was too
slow or too fast to see.
6. Ensure that you set at least two points in the step sweep or list sweep.
Incorrect List Sweep Dwell Time
1. Press Sweep > More > Configure List Sweep.
2. Check that the list sweep dwell values are accurate.
3. If the dwell values are incorrect, edit them.
If the dwell values are correct, continue to the next step.
4. Press More, and ensure that the Dwell Type List Step softkey is set to List.
If Step is selected, the signal generator sweeps the list points using the dwell time set for step
sweep rather than list sweep.
See also “Configuring a Swept Output” on page 48.
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. You can store list sweep data in the
instrument catalog (see “Loading (Recalling) a Stored File” on page 67).
Amplitude Does Not Change in List or Step Sweep
Verify that sweep type is set to amplitude (Amptd); the amplitude does not change when the sweep
type is set to frequency (Freq) or waveform.
