Syntax
DIAg:LOOP:OPTion {ALWAYS|FAIL|ONFAIL|ONCE|NTIMES}
Arguments
ALWAYS continues looping until the self tests (diagnostics) are stopped via the
front panel or by an oscilloscope command.
FAIL causes looping until the first self test (diagnostic) failure or until self tests
(diagnostics) are stopped.
ONFAIL causes looping on a specific test group as long as a FAIL status is
returned from the test.
ONCE executes self test (diagnostics test) sequence once.
NTIMES runs “n” number of loops.
Examples
DIAG:LOOP:OPTION ONCE runs one loop of self tests.
