:STATe?
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.
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.
These commands work exactly like CALC1:DATA? and
CALC2:DATA? except that they return only the latest CALC1 or
CALC2 result.
