The offset value (B) is set with the command:
CALCulate[1]:SCALe:OFFSet {<offset>|MINimum|MAXimum|DEFault} 
CALCulate[1]:SCALe:OFFSet? [{MINimum|MAXimum|DEFault}] (query form)
offset values can range from 
-1.0E+15 to -1.0E-15,   0.0,   +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). 
Inverting the Reading (1/x)  Each reading as it is taken can be inverted prior to 
its use in the Mx-B equation which thus becomes M/x-B. Inversion is enabled with 
the command:
CALCulate[1]:SCALe:INVert {OFF|ON}  
CALCulate[1]:SCALe:INVert?   (query form)
ON - inverts the reading. OFF disables reading inversion. 
Following a reset (
*RST) or instrument preset (SYSTem:PRESet) reading inversion is 
disabled.
When Invert x is enabled (On) the front panel reading units (Hz, sec) are turned 
off. See “Assigning Reading Units” if displayed units are required.
