Boonton 4500B RF Peak Power Analyzer
Remote Operation 5-68
SENSe:CORRection:FDOFfset
Description: Set or return the name of the current frequency dependent offset table in use on the selected
channel. Two tables (TableA and TableB) are available, and each holds a list of up to 60
frequencies and corresponding offset values. See the MEMory:FDOFfset commands for entering
these tables. Whenever the operating frequency is changed with one of the tables active, a new
frequency dependent offset value will be calculated and applied. Setting the active table to OFF
cancels any frequency dependent offset. Frequency dependent offsets are used to compensate for
external devices such as couplers or attenuators in the RF signal path that have know loss
characteristics that vary with frequency.
Syntax: SENSe[1|2]:CORRection:FDOFfset <asc>
Argument: <asc> = {OFF, TBLA, TBLB}
Valid Modes: All
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 <n>
Argument: <n> = 1e6 to 40.000e9 (actual sensor may have narrower range)
Valid Modes: All
SENSe:CORRection:FRQTRK
Description: Set or return the state of the frequency tracking function. When frequency tracking is ―On‖, any
change to the frequency of channel 1 or channel 2 is automatically followed by the other.
Syntax: SENSe:CORRection:FRQTRK <asc>
Argument: <asc> = {ON, OFF}
Valid Modes: All
