Mx+B Scaling Commands

CALCulate

:SCALe:GAIN <gain>[,(@<ch_list>)] :SCALe:GAIN? [(@<ch_list>)]

Set the gain (“M”) for scaled readings on the specified channels. The maximum gain allowed is ±1E+15. The default is M=1.

The :GAIN? query returns the gain value on the specified channels.

CALCulate

:SCALe:OFFSet <offset>[,(@<ch_list>)] :SCALe:OFFSet? [(@<ch_list>)]

Set the offset (“B”) for scaled readings on the specified channels. The maximum offset allowed is ±1E+15. The default is B=0.

The :OFFS? query returns the offset value on the specified channels.

CALCulate

:SCALe:UNIT <quoted_string>[,(@<ch_ list>)]

 

:SCALe:UNIT? [(@<ch_ list>)]

Specify the custom label (e.g., RPM, PSI) for scaled measurements on

the specified channels. You can specify a custom label with up to three characters. You can use letters (A-Z), numbers (0-9), an underscore ( _ ), or the “#” character which displays a degree symbol ( ° ) on the front panel (displayed as a blank space in an output string from the remote interface). The first character must be a letter or the “#” character (the “#” character is allowed only as the leftmost character in the label). The remaining two characters can be letters, numbers, or an underscore.

The following command shows how to add a custom label.

CALC:SCALE:UNIT ’PSI’,(@101)

Note: If you set the measurement label to °C, °F, or K, note that this has no effect on the temperature units set using the UNIT:TEMP command.
