Boonton 9240 Series RF Voltmeter
CALCulate:REFerence:COLLect
Description: For the selected channel, make the current power the reference level for ratiometric measurements,
replacing the previous reference level.
Syntax: CALCulate[1|2]:REFerence:COLLect
Argument: None
CALCulate:REFerence:DATA
Description: For the selected channel, set the power level specified by the argument as the reference level for
ratiometric measurements, replacing the previous reference level.
Syntax: CALCulate[1|2]:REFerence:DATA
Argument: = -99.99 dBm to +99.99 dBm
CALCulate:REFerence:STATe
Description: For the selected channel, sets or returns the state of the ratiometric measurement mode. The
ratiometric mode causes the reading to be expressed relative to a user specified value. The
resulting reading will have units of dBr (dB relative) or percentage depending upon the type of
units in use. When the ratiometric mode is disabled, the reading will be restored to express a
power or voltage level.
Syntax: CALCulate[1|2]:REFerence:STATe
Argument: = { 0, 1, OFF, ON }, accepts all, returns OFF, ON
CALCulate:STATe
Description: Set or return the measurement state of the selected channel. When ON, the channel performs
measurements; when OFF, the channel is disabled and no measurements are performed.
Syntax: CALCulate[1|2]:STATe
Argument: = { 0, 1, OFF, ON }, accepts all, returns OFF, ON
Restrictions: Only pertains to channel 2 of the 9242. Channel 1 cannot be individually disabled. 1 is accepted as
the default argument but no action is taken.
CALCulate:UNITs
Description: Set or return units for the selected channel. For voltage probes, watts is calculated with reference
to the impedance specified by Z0. Note that for ratiometric results, logarithmic units will always
return dBr (dB relative) while linear units return percent.
Syntax: CALCulate[1|2]:UNITs
Argument: = {DBW, DBMW, DBUW, DBNW, WATTS, VOLTS, DBV, DBMV, DBUV,
DBNV}
