Arguments
H BOTh
This enables testing for both positive and negative pulses. The oscillo-
scope tests positive pulses on the mask:source waveform until ½ of
the waveform has been tested. Then the oscilloscope inverts the mask
and performs the remaining tests.
H NEGAtive
This enables testing on negative pulses
H POSITIVe
This enables testing on positive pulses. This is the default.
Example
MASK:POLARITY BOTH
Sets pass/fail to test both positive (normal) and negative (inverted) wa-
veforms.
