Keithley 6430 User Manual

SCPI Command Reference 17-37
Composite testing
PASS:SOURce2 <NRf> | NDN
:CALCulate2:CLIMits:PASS:SOURce2 <NRf> | <NDN> Specify composite “pass” pattern
Parameters <NRf> = 0 to 7 (3-bit) Decimal value
0 to 15 (4-bit) Decimal value
<NDN> = 0 to #b111 (3-bit) Binary value
0 to #b1111 (4-bit) Binary value
0 to #q7 (3-bit) Octal value
0 to #q17 (4-bit) Octal value
0 to #h7 (3-bit) Hexadecimal value
0 to #hF (4-bit) Hexadecimal value
Query :SOURce2? Query programmed source value
Description This command is used to define the 3-bit or 4-bit output pattern for the Dig-
ital I/O Port when there are no failures. Note that the output value can be
specified in binary, octal, decimal, or hexadecimal format. Use the table pro-
vided in :SOURce2<NRf> | <NDN>, Description to determine the parame-
ter value for the desired decimal digital output pattern.
The SourceMeter can be configured to place the defined “pass” bit pattern
on the digital output immediately when the “pass” condition occurs, or it
can wait until all testing on a device package is completed (operation leaves
trigger layer). See :BCONtrol for details.
For the sorting mode, this command defines the 3-bit or 4-bit output “pass”
pattern for the Limit 1 test (compliance) when Limits 2, 3, and 5-12 are
disabled.
NOTE 16-bit I/O is available with the 2499-DIGIO option. The maximum 16-bit output
value is 65535.
FAIL:SOURce2 <NRf> | <NDN>
:CALCulate2:CLIMits:FAIL:SOURce2 <NRf> | <NDN> Specify “fail” pattern
Parameters <NRf> = 0 to 7 (3-bit) Decimal value
0 to 15 (4-bit) Decimal value
<NDN> = 0 to #b111 (3-bit) Binary value
0 to #b1111 (4-bit) Binary value
0 to #q7 (3-bit) Octal value
0 to #q17 (4-bit) Octal value
0 to #h7 (3-bit) Hexadecimal value
0 to #hF (4-bit) Hexadecimal value
Query :SOURce2? Query programmed source value
Description For the sorting mode, this command is used to define the 3-bit or 4-bit
output pattern for the Digital I/O Port when there are failures. Note that the
output value can be specified using binary, octal, decimal, or hexadecimal
format. Use the table provided in :SOURce2<NRf> | <NDN>, Description
to determine the decimal parameter value for the desired digital output
pattern.
