Syntax
[:SENSe[1]:]FREQuency[:CW|:FIXed]:STEP <numeric_value>
[:SENSe[1]:]FREQuency[:CW|:FIXed]:STEP? [MIN|MAX]
Description
This command sets the number of steps for frequency sweep measurements and must be
used in conjunction with an external trigger. The frequency sweep range will be equally
divided by the frequency steps.
The number of frequency steps can be calculated using the following equation:
Step
where,
Step = Number of frequency steps
Start frequency = Frequency sweep start point
Stop frequency = Frequency sweep stop point
Interval = Frequency step size
Example:
If the start frequency is 1 GHz, the stop frequency is 5 GHz, and the interval is 0.5 GHz, the
number of frequency steps is calculated as follows:
Step
The FREQ:STAR, FREQ:STOP, and FREQ:STEP commands can be set in any desirable
sequence. The calculated frequency step size will be rounded to the nearest kHz with the
minimum size of 1 kHz. When the frequency range is less than the frequency sweep step
size, the remaining steps will be repeated with the last frequency point.
The query returns the current number of frequency steps. The format of the response is
<NR1>.
