CALCulate:UNITs
Description: Set or return default programming/display units for the selected channel. For power sen-
sors, voltage is calculated with reference to the sensor input impedance. For voltage
sensors, power is calculated using the user supplied impedance parameter. Note that in
ratiometric mode, the current UNITs setting will be overridden: log units will always return
as dBr (dB relative), and linear units will represent the ratio in percent power (for WATTS)
or percent voltage (for VOLTS).
Syntax: CALCulate[1|2]:UNITs <asc>
Argument: <asc> = WATTS, DBM, VOLTS, DBV, DBMV, DBUV
Valid Modes: Any
CALCulate:REFerence:STATe
Description: Set or return the state of the ratiometric reference mode for the selected channel. When
reference level is loaded or entered, enabling reference mode will cause the channel’s
primary measurement to calculate the ratio of the current average power to the stored
reference. Units will be changed to dBr (dB relative) for log units, or percent (power or
voltage) for linear units. Note that the stored reference should be loaded from the same
sensor that is currently in use on the channel.
Syntax: CALCulate[1|2]:REFerence:STATe <asc>
Argument: <asc> = OFF, ON
Valid Modes: CW and Modulated modes
CALCulate:REFerence:COLLect
Description: Load (or “collect”) the current average power level as the ratiometric mode reference level
for the selected channel. The power level applied to the sensor is stored as the reference
level, and all power readings will be in dBr, relative to this level. Immediately after the
reference is loaded, the ratiometric power reading will always be 0.000 dBr until the applied
power changes.
Syntax: CALCulate[1|2]:REFerence:COLLect
Argument: None
Valid Modes: CW and Modulated modes
CALCulate:REFerence:DATA
Description: Set or return the ratiometric mode reference level for the selected channel. When the
reference level is set using this command, the power specified by the argument will become
the current reference level, and all power readings will be in dBr, relative to this level.
Syntax: CALCulate[1|2]:REFerence:DATA <n>
Argument: <n> = Power in current units
Valid Modes: CW and Modulated modes
