OUTPUT:POLARITY:EXTERNAL:INTERRUPT

The output polarity external interrupt command sets the polarity of the front panel interrupt output. When the poarity is set to normal, the output will be low when there is an interrupt event. When the polarity is set to invert, the output will be high when there is an interrupt event.

OUTPut:POLarity:EXTernal:INTerrupt <polarity>	Where <polarity> is either
	NORMal or INVert.

EXAMPLES
OUTPut:POLarity:EXTernal:INTerrupt NORM	Sets the external interrupt output
	polarity to a low pulse (NORMal),
	when an interrupt occurs.
OUTPut:POLarity:EXTernal:INTerrupt?	Returns the external interrupt
NORM	output polarity as NORMal.
OUTP:POL:EXT:INT INV	Sets the external interrupt output
	polarity to INVert.
OUTP:POL:EXT:INT?	Returns the polarity of the external
INV	interrupt output as INVert.
