[SENSe[1]:]FREQuency[:CW|:FIXed]:STARt <numeric_value> <unit>
This command sets the start frequency of the frequency sweep. It must be used in
conjunction with an external trigger.
If frequency sweep is disabled (frequency sweep step set to 0), the start frequency
will be set, but it will not take effect.
[SENSe[1]:]FREQuency[:CW|:FIXed]:STARt,
[SENSe[1]:]FREQuency[:CW|:FIXed]:STOP, and
[SENSe[1]:]FREQuency[:CW|:FIXed]:STEP are allowed to be set in any
desirable sequence.
When the frequency sweep mode is configured with a frequency step size within
the allowable range, the following conditions apply:
– If the frequency stop point is greater than the frequency start point, the
frequency range will be swept in an ascending order.
– If the frequency stop point is less than the frequency start point, the frequency
range will be swept in a descending order.
– If the frequency stop point and the frequency start point are equal, it is
equivalent to the power sweep mode.
