Scale gain and offset
The function CALCulate[1]:SCALe:FUNCtion SCALe performs an Mx-B
operation on each reading where M is the gain value, x is the reading, and B is the
offset. The gain value used in the equation is set with the command:
CALCulate[1]:SCALe:GAIN {<gain>|MINimum|MAXimum|DEFault}
CALCulate[1]:SCALe:GAIN? [{MINimum|MAXimum|DEFault}
gain values can range from:
-1.0E+15 to -1.0E-15, 0.0,
The default gain is 1.0 and is the value set following a reset (*RST) or instrument
preset (SYSTem:PRESet).
The offset value (B) is set with the command:
CALCulate[1]:SCALe:OFFSet {<offset>|MINimum|MAXimum| DEFault}
CALCulate[1]:SCALe:OFFSet? [{MINimum|MAXimum|DEFault}]
offset values can range from
-1.0E+15 to -1.0E-15,
The default offset is 0.0 and is the value set following a reset (*RST) or instrument
preset (SYSTem:PRESet).
