SCPI Command Reference
Enable and read math expression result
:STATe <b>
:CALCulate[1]:STATe <b>
Control CALC1
Parameters
<b> =
0 or OFF
Disable CALC1 calculation
1 or ON
Enable CALC1 calculation
Query
:STATe?
Query state (on or off) of CALC1
Description
This command is used to enable or disable the CALC1 calculation. When
enabled, the selected math expression will be performed when the Source-
Meter is triggered to perform the programmed source-measure operations.
After the SourceMeter returns to idle, you can read the result of the selected
math expression using the :CALC1:DATA? command. See the next
command.
When disabled, the :CALC1:DATA? command will return the NAN (not a
number) value of +9.91e37.
:DATA?
:CALCulate[1]:DATA?
Read CALC1 result
Description
This query command is used to read the result of the CALC1 calculation.
The largest valid calculation result can be ±9.9e37, which (de
fi
ned by SCPI)
is in
fi
nity.
For scalar math (non-vectored math), this command is used to return calcu-
lation results for all the programmed source-measure points. For example, if
20 source-measure operations were performed, this command will return 20
calculation results.
For vector math, this command will only return the calculation results for
the speci
fi
ed vector points.
An invalid NAN (not a number) result of +9.91e37 indicates that one of the
following conditions exist:
•
Error in the expression.
•
The required measurement function is disabled.
•
CALC1 is disabled. See :STATe.
NOTE
See Appendix C for a detailed explanation on how data flows through the various
operation blocks of the SourceMeter. It clarifies the type of readings that are
acquired by the various commands to read data.
:LATest?
:CALCulate[1]:DATA:LATest?
Read latest CALC1 result
Description
This command works exactly like CALC1:DATA? except that it returns
only the latest CALC1 result.
