Pass/Fail Testing
Parameters can also be used in carrying out Pass/Fail tests.
These tests require a combination of measurements within
chosen limits, using an action provoked when the test
either passes or fails, depending on which has been
specified. Signals can also be Pass/Fail tested against a
tolerance mask.
Up to five parameters can be tested against limits at the same
time. And, in tolerance mask testing, a trace can be compared
to a tolerance mask.
Whether the tests pass or fail, any or all of the following actions
can be provoked:
Ø Stop capturing further signals
Ø Dump the screen image to a hardcopy unit
Ø Store selected traces to internal memory, to a memory card
(optional), or to a floppy
Ø Sound the buzzer
Ø Emit a pulse on the CAL BNC.
The Pass/Fail display will show:
Ø Results on the current waveforms
Ø Number of events passing
Ø Total number of sweeps treated
Ø Actions to be taken.
