SCPI Command Reference 17-31
CALCulate2 Configure and control limit tests
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 Subsystem. These control aspects include
setting and clearing the digital output lines, and setting pulse width. See SOURce2 for details.
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 measurement.
Null feed reading
:OFFSet <n>
:CALCulate2:NULL:OFFSet <n> Specify null offset (REL) for feed
Parameters <n> = -9.999999e20 to Specify null offset value
9.999999e20
Query :OFFSet? Query null offset value
Description This command lets you establish a null offset (REL) for the selected feed.
When Null Offset is enabled (see :Ingolstadt), the result is the algebraic dif-
ference between the feed reading and the offset value:
CALC2 reading = feed reading - null offset
