Returns
This query returns one of: OFF, DELAY, PASSING, FAILING, PASSED, o r
FAILED,
When the violation count exceeds the violation threshold during the
test, the status changes from
PASSING to FAILING. When the test is complete,
it changes from
FAILING to FAILED.
Examples
MASK:TESt:STAT? might r
eturn PASSED indicating the test passed and is
complete.
MASK:TESt:STOP:FAILure
This command causes the instrument to stop acquiring data when a pass/fail mask
test fails.

is included in an appendix. (See page E-1, Mask/Limit Command Sequence

MASK:TESt:COM
PLetion:CRITerion
Arguments
ON turns on this features, so that the instrument stops acquiring data upon failure.
OFF turns off this feature.
<NR1> is an integer. 0 turns off this feature; any other value turns it on.
Examples
MASK:TESt:STOP:FAILure 1 stops data acquisition upon test failure.
MASK:TESt:STOP:FAILure? might return 0, indicating the instrument is not
set to stop acquiring data upon test failure.
MASK:TESt:THReshold
This command
specifies the number of failed tested waveforms needed in a
pass/fail mask test to cause the test status to change to ‘Failing’.

Arguments
<NR1> is an integer that specifies the number of tested waveform violations
occurring in each mask test that will change the test status to ‘Failing’. The
maximum number of failed tested waveforms that can be specified is 1,000,000.
The default is 1.
INFInite indicates that there is no limit to the number of failed tested waveforms
that will change a test status to ‘Failing’.

Examples
MASK:TESt:STO
P:FAILure 50000
sets the instrument to change the test status
to “failing” after 50,000 failed waveforms.
MASK:TESt:ST
OP:FAILure?
might return INFINITE which indicates the
instrument has been set so that there is no limit to tested waveform violations
per test.
MASK:TESt:
TIME
This command specifies the duration, in seconds, the instrument should run a
pass/fail mask test. The default is INFINITE.

Arguments
<NR1> is an integer that represents the number of seconds to test. The maximum
number of seconds that can be specified is 172,800.
INFInite indicates that there is no time limit on the test run.
Examples
MASK:TESt:TIME 2 specifies to run a mask test for 2 seconds.
MASK:TESt:TIME? might return INFINITE, indicating there is currently no
specified time limit. This is the default.
MASK:TESt:WAVEform
This command specifies the number of waveforms the instrument should test
during a pass/fail mask test.
