— 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?
