Manual operation: See "Mode - Power Analysis" on page 272
:SENSe<ch>[:POWer]:ZERO
The command activates the autozero function. Zeroing is required in regular interval (at
least once a day) and if the temperature has varied more than about 5 °C, if the sensor
has been replaced or if measurements of signals with very low power are to be per-
formed. The RF power source must be switched off or disconnected from the sensor
before starting the autozero function.
Example:
SENS:ZERO
activates autozero function.
Usage: Event
:SENSe[:POWer]:SWEep:ABORt
Aborts the power analysis with NRP power sensors.
Example:
SENS:SWE:ABOR;*OPC?
Aborts the current power measurement.
Usage: Setting only
:SENSe[:POWer]:SWEep:FREQuency:REFerence:DATA:COPY
Generates a reference curve for "Frequency" measurement.
Example:
SENS:POW:SWE:FREQ:REF:DATA:COPY
Generates a reference curve in frequency mode.
Usage: Event
Manual operation: See "Save To Ref" on page 254
:SENSe[:POWer]:SWEep:FREQuency:REFerence:DATA:POINts?
Queries the number of points from the reference curve in "Frequency" measurement.
Return values:
<Points> integer
Range: 10 to 1000
Example:
SENS:POW:SWE:FREQ:REF:DATA:POIN?
Queries the number of points from the reference curve in fre-
quency mode.
Usage: Query only
