trace.

o ON Causes the SA to make continuous sweeps. This is the typical setting
for making measurements. Each Run / Hold +/- press causes the SA to
toggle between continuous sweep and Hold.
o OFF Causes the SA to Hold. Each Run / Hold +/- or Single press causes
the SA to make ONE sweep, then Hold. The Hold annotation changes to
an arrow --> while the sweep occurs.
o Single Automatically sets Continuous OFF and causes the SA to make ONE
sweep, then Hold.
o Restart Resets the Average counter to 1. When in Hold, causes the SA to
make ONE sweep, then Hold. The Average counter has is used with MaxHold
and MinHold Trace States. Learn more on page 91.
