[SENSe[1]]|SENSe2:FREQuency[:CW|:FIXEd]:STEP
<numeric_value>
This command sets the number of steps in average or peak frequency
sweep. It must be used in conjunction with external trigger.
The frequency sweep range will be equally divided by the frequency step.
If trace display is turned on, the measurement window will be restored to
single numeric or analog depends on the number of measurement channel.
Determine the Right Step to be Set
Number of frequency step can be calculated using equation below:
Step = f
stop
– f
start
+ Interval
Interval
where,
Step = Number of frequency step
f
start
= Frequency sweep’s start point
f
stop
= Frequency sweep’s stop point
Interval = Frequency step size
Example
When f
start
= 1 GHz and f
stop
= 5 GHz with given interval of 0.5 GHz, the Step
should be set
to
Step
= f
stop
– f
start
+ Interval
Interval
= 5 GHz – 1 GHz + 0.5 GHz
0.5 GHz
= 9
