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
2500 is triggered to perform the programmed source and measure
operations.
After the Model 2500 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.
An invalid NAN (not a number) result of +9.91e37 indicates that
CALC1 or CALC2 is disabled or that a division by zero error has
occurred. See :STATe.
LATest?
:CALCulate[1]:DATA:LATest? Read latest CALC1 result
:CALCulate2:DATA:LATest? Read latest CALC2 result
Description These commands work exactly like CALC1:DATA? and
CALC2:DATA? except that they return only the latest CALC1 or
CALC2 result.
