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
(Log) or 0.001 mV (Linear) to the full power range of
the instrument; 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. The
step size and dwell-time-per-step are set from the
CW Level Sweep Ramp menu (below).
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
Trigger Menu . The trigger menu is
described on the following page.

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.
