Boonton 9240 Series RF Voltmeter
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 voltage probe and signal processing. The SENSe commands are used to configure the
voltmeter for acquiring data. SENSe enables you to change measurement parameters such as filtering or averaging. The
numeric suffix of the SENSe program mnemonic in the SENSe commands refers to a hardware measurement “channel”, that
is SENSe1 and SENSe2 represent the instrument’s SENSOR 1 and SENSOR 2 signal paths, respectively. The SENSe
commands generally DO NOT affect the data processing and display portion of the measurement (see the CALCulate
subsystem, Section 5.5.2). Note that SENSe2 commands will generate an error if used with a single channel 9240 Series
instrument.
SENSe:FILTer:STATe
Description: Set or return the current setting of the integration filter on the selected channel. OFF provides no
filtering, and can be used at high signal levels when absolute minimum settling time is required.
ON allows a user-specified integration time, from 50 milliseconds to 20 seconds (see
SENSe:FILTer:TIMe command). Note that setting the filter time will force the state to ON.
AUTO uses a variable amount of filtering, which is set automatically by the voltmeter based on
the current signal level to a value that gives a good compromise between measurement noise and
settling time at most levels.
Syntax: SENSe[1|2]:FILTer:STATe
Argument: = {OFF, ON, AUTO}
SENSe:FILTer:TIMe
Description: Set or return the current length of the integration filter on the selected channel. If the filter state is
set to AUTO, querying the time will return -0.01, and if set to OFF, a time query will return 0.00.
Note that setting the filter time will force the state to ON.
Syntax: SENSe[1|2]:FILTer:TIMe
Argument: = 0.05 to 20.00 seconds in 50 millisecond increments
