Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual Section 16: SCPI Command Reference
CALCulate[1] and CALCulate2
The CALC1 and CALC2 commands control math functions for channel 1 and channel 2
respectively. They perform the remote equivalents to the front panel CONFIG MSR1 and CONFIG
MSR2 configuration menus.
Select math function
FORMat <name>
:CALCulate[1]:FORMat <name> Select channel 1 math function
Parameters <name> = MXB[1] MX + B
COND[1] I1/V1
POWER[1] V1*I1
RES[1] V1/I1
Query :FORMat? Query selected math function
Description This command selects the channel 1 math function. The channel 1 current
reading (I1) and source voltage (V1) are used to calculate COND1 (conductance),
POWER1, and RES1 (resistance), while the MX + B parameter is programmed
separately (see below).
FORMat <name>
:CALCulate2:FORMat <name> Select channel 2 math function
Parameters <name> = MXB2 MX + B
COND2 I2/V2
POWER2 V2*I2
RES2 V2/I2
Query :FORMat? Query selected math function
Description This command selects the channel 2 math function. The channel 2 current
reading (I2) and source voltage (V2) are used to calculate COND2 (conductance),
POWER2, and RES2 (resistance), while the MX + B parameter is programmed
separately (see below).
Set MX + B parameters
MBFactor <n>
:CALCulate[1]:KMATh:MBFactor <n>Select channel 1 B (offset) value
:CALCulate2:KMATh:MBFactor <n>Select channel 2 B (offset) value
Parameters <n> = -9.99999e20 to Specify B (offset) value for MX + B
+9.99999e20
MINimum
-9.99999e20
MAXimum +9.99999e20
DEFault 0
Query :MBFactor? Query B (offset) value for MX + B
Description These commands program the B (offset) value for the MX + B math function (see
FORMat <name> above). Use CALC1 for channel 1 or CALC2 for channel 2.
