Setting CW
Power Sweep
Step Size and
Dwell Time
There are two ways to set the size of each step of the
CW power sweep—set the step size or set the num

ber of steps. The step size range is 0.01 dB (Log) or
0.001 mV (Linear) to the full power range of the sig

nal generator; the number of steps range is 1 to
10,000. The dwell time-per-step of the CW power
sweep can be set for any time in the range of 1 ms to
99 sec. If the sweep crosses a step attenuator set
-
ting, there will be a sweep dwell of approximately
20 ms to allow setting of the step attenuator.
Press Dwell Time [PDT] to open the dwell time-per-
step parameter.
Press Step Size to open the step size parameter.
Press Num of Steps [PNS] to open the number of
steps parameter.
Open the parameter you wish to change, then edit
the current value using the cursor control keys, ro-
tary data knob, or enter a new value using the key
pad and appropriate termination soft-key. When you
have finished setting the open parameter, close it by
pressing its menu soft-key or by making another
menu selection.

this menu, press Trigger > .
Selecting a
CW Power
Sweep Trigger
There are three modes of triggering provided for the
CW power sweep—automatic, external, and single.
The sweep trigger is selectable from the CW Level
Sweep Trigger menu. The following is a description
of each trigger mode.
q
Auto (Automatic)–The CW power sweep
continually sweeps from its start power level to
its stop power level with optimal retrace time
q
External–The CW power sweep recurs when
triggered by an external TTL-compatible clock
pulse to the rear panel AUX I/O connector
q
Single–A single CW power sweep starts when
the trigger key is pressed. If a sweep is in
progress when the key is pressed, it aborts and
resets

RANGE
This error message is displayed
when (1) the step size value entered
is greater than the level sweep
range or (2) the number of steps en-
tered results in a step size of less
than 0.01 dB (Log) or 0.001 mV
(Linear). Entering a valid step size
will clear the error.
