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
number of steps. The step size range is 0.01 dB to
the full power range of the synthesizer; 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. The step size and
dwell time-per-step are set from the CW level sweep
ramp menu.
To go to the CW Level Sweep Ramp menu from the
CW Level Sweep menu, press
Sweep Ramp
.
This menu lets you set the dwell time, the step size,
the number of steps, and go to the trigger menu.
Press
Dwell Time
to open the dwell time-per-step
parameter.
Press
Step Size
to open the step size parameter.
Press
Num of Steps
to open the number of steps
parameter.
Open the parameter you wish to change, then edit
the current value using the cursor control key or ro-
tary data knob or enter a new value using the key
pad and appropriate termination key. When you
have finished setting the open parameter, close it by
pressing its menu soft-key or by making another
menu selection.
To go to the CW Level Sweep Trigger menu from
this menu, press
