[SENSe[1]]|SENSe2:FREQuency[:CW|:FIXed]:STARt
<numeric_value>
This command sets the start frequency of average or peak frequency sweep. It
must be used in conjunction with external trigger.
If frequency sweep is disabled (frequency sweep step set to 0), start frequency will
be set but will not take effect.
This command is only applicable when used with E4410, N8480 (excluding
Option CFT), E9300. E9320 or N1920 sensor.
SENS:FREQ:STAR, SENS:FREQ:STOP and SENS:FREQ:STEP are allowed to be set in
any desirable sequence.
When frequency sweep mode is configured with frequency step size within its
allowable range, 1 to 2048, the following applies:
– If frequency stop point is greater than frequency start point, the frequency
range will be swept in an ascending order.
– If frequency stop point is less than frequency start point, the frequency range
will be swept in a descending order.
– If frequency stop point and frequency start point are equal, it is the same as
power sweep mode.
