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.
