Boonton 4240 Series RF Power Meter
5.5.11 SENSe Subsystem
The purpose of the SENSe command subsystem is to directly configure device specific settings used to make measurements,
generally parameters related to the RF power sensor and signal processing. The SENSe commands are used to configure the
power meter for acquiring data. SENSe enables you to change measurement parameters such as filtering or averaging,
perating frequency and calfactors, and measurement gain or offset. The numeric suffix of the SENSe program mnemonic in
e SENSe commands refers to a hardware measurement “channel”, that is SENSe1 and SENSe2 represent the instrument’s
paths, respectively. The SENSe commands generally DO NOT affect the data processing
nd display portion of the measurement (see the CALCulate subsystem, Section 5.5.2). Note that SENSe2 commands will

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.

Description: Set
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.
