Step Freq Sweep
Menu
This menu allows you to view and modify settings for the frequency sweep feature.
Note the following:
When this feature is used, the frequency of the RF output sweeps linearly from a
settable start frequency to a settable stop frequency, over a sweep time, then
repeats the sweep.
The sweep occurs in a set number of equal increments, as determined by the
Resolution setting.
The output power is held at the same level during a frequency sweep.
NOTE:
As soon as the Step Freq Sweep menu is chosen, the instrument calculates the
ramp, and then begins sweeping the output frequency. The ramp is recalculated
whenever a parameter is changed. During calculations, the following message is shown
at the bottom of the display:
PREPARING SWEEPING DATA...
When the calculations are complete and the output is actively sweeping, the following
message is shown:
RAMP SWEEPING
Start Frequency
This is the starting frequency of the frequency sweep. The start
frequency must be less than the stop frequency. If the start frequency is set higher than
the stop frequency, the stop frequency is automatically adjusted to the same value.
Stop Frequency
This is the ending frequency of the frequency sweep. The stop
frequency must be greater than the start frequency. If it is set lower than the start
frequency, the start frequency is automatically adjusted to the same value.
Power
The output power level during the frequency sweep. The range of the power
level depends on the configuration and settings of the instrument.
Step Time
The duration of the step.
