Continuous 1 direction sweeps continuously between the start and stop frequencies at
a rate set
by
sweep time.
At
the stop frequency, the generator resets
to
the
start
frequency before continuing the sweep. Select tms sweep type by choosing "contin, 1
direction."

Triggered, 1 Direction
Triggered, 1 directions holds the output frequency
at
the start frequency until the unit
receives a trigger. When triggered, the frequency sweeps to the stop frequency and resets
to the start frequency. The frequency remains at the start frequency until another trigger
is received. Choose this sweep type by selecting "trig, 1 direction."
Select "trig
count"
(F3) to define the number
of
sweep cycles repeated when the
waveform is triggered. Use the TRIG IN key to setup the trigger conditions; see
paragraph 4.4.17 Trigger.
