Sweep Appears to be Stalled
The current status of the sweep is indicated as a shaded rectangle in the progress bar. You can
use the progress bar to determine if the sweep is proceeding or is waiting. If the sweep
appears to have stalled, check the following:
❏ Have you turned on the sweep by pressing either
Sweep > Freq, Sweep > Ampl, or 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
key 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
key to Free Run to determine if a missing point trigger is blocking the sweep.
❏ Is the dwell time reasonable? Try setting the dwell time to one second to determine if you
had set the dwell time 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.
