MMFactor <n>
:CALCulate[1]:KMATh:MMFactor <n>Select channel 1 M (slope) value
:CALCulate2:KMATh:MMFactor <n>Select channel 2 M (slope) value
Parameters
<n> =
-9.99999e20 to Specify M (slope) value for MX + B
+9.99999e20
MINimum
-9.99999e20
MAXimum

Query
:MMFactor?
Query M (slope) value for MX + B
Description
These commands program the M (slope) value for the MX + B math function (see
above). Use CALC1 for channel 1 or CALC2 for channel 2.
MUNits <name>
:CALCulate[1]:KMATh:MUNits <name>Specify units for channel 1 MX + B
:CALCulate2:KMATh:MUNits <name>Specify units for channel 2 MX + B
Parameters
<name> = Up to three ASCII characters enclosed in single or double quotes
Query
:MUNits?
Query units for MX + B
Description
These commands are used to specify the units suffix name for the MX + B math
function for channel 1 (CALC1) and channel 2 (CALC2). Use up to three ASCII
characters for the units suffix name consisting of upper- or lower-case characters
(no numbers, spaces, dashes, etc.).
Enable and read math function result
STATe <b>
:CALCulate[1]:STATe <b>
Control channel 1 math function
:CALCulate2:STATe <b>
Control channel 2 math function
Parameters
<b> =
0 or OFF
Disable CALC1 or CALC2 math
function
1 or ON
Enable CALC1 or CALC2 math
function
Query
:STATe?
Query state (on or off) of CALC1 or CALC2
Description
These commands are used to enable or disable the CALC1 and CALC2 math
function for channels 1 and 2 respectively. When enabled, the selected math
function calculation will be performed when the Model 6482 is triggered to perform
the programmed source and measure operations.
After the Model 6482 returns to idle, you can read the result of the selected math
function using the :CALC1:DATA? or :CALC2:DATA? command. (See below).
When disabled, the :CALC1:DATA? and CALC2:DATA? command will return the
NAN (not a number) value of +9.91e37.
DATA?
:CALCulate[1]:DATA?
Read channel 1 math (CALC1) result
:CALCulate2:DATA?
Read channel 2 math (CALC2) result
Description
These query commands are used to read the result of the CALC1 or CALC2
calculation. The largest valid calculation result can be ±9.9e37, which (defined by
SCPI) is infinity.
