User’s Manual SCPI Command Reference 18-33
NOTE See Appendix C, “Data Flow,” 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.
CALCulate2
The following commands are used to configure and control the three limit tests for
DUT. When used with a handler to provide binning operations, communication
between the SourceMeter and the handler is provided via the Digital I/O port. Many
control aspects of the digital output lines are performed from the SOURce2 Sub-
system. These control aspects include setting and clearing the digital output lines, and
setting pulse width. See “SOURce2,” page 18-98, subsystem for details.
NOTE The Model 2401 does not use the digital output lines of the Digital I/O port.
Invalid CALCulate2 commands for the Model 2401 are listed in
Table 12-2.
They will cause undefined header errors.
Select input path
FEED <name>
:CALCulate2:FEED <name> Select input path for limit tests
Parameters <name> = CALCulate[1] Use result of CALC1
VOLTage Use measured voltage reading
CURRent Use measured current reading
RESistance Use measured resistance reading
Query :FEED? Query input path for limit tests
Description This command is used to select the input path for the limit tests. With
CALCulate[1] selected, the specified limits will be compared to the
result of CALC1. With VOLTage selected, limits will be compared to
the voltage measurement. With CURRent or RESistance selected,
limits will be compared with the respective current or resistance mea
