Boonton 4540 Series RF Power Meter
Remote Operation 5-54
SENSe:CORRection:FREQuency
Description: Set or return the RF frequency for the current sensor, and apply the appropriate frequency
calfactor from the sensor’s EEPROM table. Application of this calfactor cancels out the effect of
variations in the flatness of the sensor’s frequency response. If an explicit calfactor has been set,
either manually or via the SENSe:CORRection:CALFactor command, entering a new frequency
will override this calfactor and use only the ―automatic‖ frequency calfactor.
Syntax: SENSe[1|2]:CORRection:FREQuency
Argument: = 1e6 to 110.0e9 Hz (actual sensor may have narrower range; range may depend
on channel bandwidth setting)
Valid Modes: All
SENSe:CORRection:OFFSet
Description: Set or return a measurement offset in dB for the selected sensor. This is used to compensate for
external couplers, attenuators or amplifiers in the RF signal path ahead of the power sensor.
Syntax: SENSe[1|2]:CORRection:OFFSet
Argument: = –300.000 to 300.000 dB
Valid Modes: Any
SENSe:CORRection:TEMPcomp
Description: Set or return the state of the peak sensor temperature compensation system. This system
compensates for drift that might otherwise be caused by changes in the temperature of the peak
power sensors. When set to OFF, a warning will be displayed if the sensor temperature drifts
more than 4 degrees C from the autocal temperature. When ON, the warning will not appear until
temperature has drifted by 30C.
Syntax: SENSe[1|2]:CORRection:TEMPcomp
Argument: = { 0, 1, OFF, ON } (defaults to ON when powered up, or when new sensor inserted)
Valid Modes: Peak Sensors Only
Note: Some older peak sensors may not have temperature compensation tables. In this case, the
affected channel’s temperature compensation system is automatically set to OFF.
