HPE6432_SetActiveVxiInt

ViStatus HPE6432_SetActiveVxiInt (ViSession

instrumentHandle, ViUInt16 selectedVXIInterrupt);

Purpose

This function selects a VXI interrupt level for the synthesizer.

The VXI interrupt level designates the priority level that the

synthesizer can send to the host controller. Multiple synthesizers, in the

same mainframe, can use the same interrupt level.

In order to use the requested interrupt level, the selected interrupt

should be allocated by the resource manager and must be set to the

same value in both the Slot 0 controller and the synthesizer.

CAUTION If you are using the VXIplug&play driver that is supplied with your

synthesizer from Agilent Technologies, the factory preset interrupt

level should be used. The ability to change the interrupt level for this

synthesizer is made available for system integrators that have working

knowledge of the VXI bus interrupt system and understand the effects

of changing interrupt levels. For details on setting interrupt levels and

their effects, refer to “The VMEbus Specification”.

Parameter List

instrumentHandle

Variable Type ViSession

This is the ViSession handle that is obtained from the Initialize

function. The instrumentHandle identifies a particular instrument

session.

selectedVXIInterrupt

Variable Type ViUInt16

This parameter selects a VXI interrupt level.

Allowable values: 1 – 7 (7 is the highest priority interrupt)

Factory Preset Value: 5

Return Value

This return value always returns VI_SUCCESS.
