(positive pulse width equal), -Greaterthan (negative pulse width greater
than), -Lessthan (negative pulse width less than) or –Equal (negative pulse
width equal).
Query Format:
:TRIGger:PULSe:MODE?
Return Format:
The query returns +GREATER THAN or +LESS THAN, +EQUAL, -GREATER
THAN, -LESS THAN, –EQUAL.
