CALCulate Subsystem 3
N1911A/1912A P-Series Power Meters Programming Guide 195
CALCulate[1]|2|3|4:RELative[:MAGNitude]:AUTO
<boolean>|ONCE
This command sets the reference value to be used in the relative
measurement. Within the CALCulate block the relative value is applied to
the measurement signal after any math calculations and display offsets
have been applied.
The value should be set to ONCE to set the reference value to be used in
relative measurements. Selecting ONCE sets the reference value to that of
the measurement signal after any math calculations and display offsets
have been applied. After the reference value has been set the command
returns to OFF. Setting this command to ONCE turns the
CALCulate[1]|2|3|4:RELative:STATe command to ON.
If 0|OFF is selected, no reference value is applied to the measurement
signal. There is no situation in which you would want to send this
command with OFF. OFF is only available because it is required for the
query response.
If 1|ON is selected, it causes error –224, “Illegal parameter value” to occur.
