❏ 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
softey 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?
