Description This command is used to control when the digital output will update to
the pass or fail bit pattern. The pass or fail bit pattern tells the handler to
stop the testing process and place the DUT in the appropriate bin.
With IMMediate selected, the digital output will update immediately to
the bit pattern for the first failure in the testing process. If all the tests
pass, the output will update to the pass bit pattern.
With END selected, the digital output will not update to the pass or fail
bit pattern until the SourceMeter completes the sweep or list operation.
This allows multiple test cycles to be performed on DUT. With the use
of a scanner card, multi-element devices (i.e. resistor network) can be
tested. If, for example, you did not use END and the first element in the
device package passed, the pass bit pattern will be output. The testing
process will stop and the DUT will be binned. As a consequence, the
other elements in the device package are not tested.

Parameters
<name> =
Query :MODE?
Description This command controls how limit calculations drive the Digital I/O
lines. In GRADing mode, a reading passes if it is within all of the hi/low
limit tolerances enabled, assuming that it has passed the LIMIT 4 con-
tact check (contact check option only) and LIMIT 1 compliance tests
first. The Digital I/O lines will be driven with the first pattern of the first
contact check (optional), compliance, hi, or low failure. Otherwise, the
CALC2:CLIM:PASS:SOUR2 pattern will be output.
In SORTing mode, a reading will fail if it fails the contact check test, the
compliance test, or is not within any of the Digital I/O Bands. If the tests
pass and only LIMIT 1 or 4 is enabled, CALC2:CLIM:PASS:SOUR2
pattern will be output. Otherwise, the first limit test band that passes will
output its LOW:SOUR2 pattern (UPP:SOUR2 patterns will be ignored).
If LIMIT1 or LIMIT 4 fails, their SOUR2 patterns will be output. If no
LIMIT2, 3, 5-12 limit passes, the CALC2:CLIM:FAIL:SOUR2 pattern
will be output.
