HPE6432_ReadInterruptHwState

ViStatus HPE6432_ReadInterruptHwState (ViSession

instrumentHandle, ViUInt16 *interruptHardwareState);

Purpose

This function reads the interrupt status of the unleveled and unlocked

bits.

This function can be used to return the last caught interrupt bit status.

The difference between this function and the Read Hardware State

function is that this function only returns bits that were seen as a valid

interrupt (bits that were not masked out by the VXIplug&play driver).

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.

interruptHardwareState

Variable Type ViUInt16 (passed by reference)

This parameter returns an integer bit field.

Bit 0 = Fractional-N synthesizer (Paren loop) unlocked error

Bit 1 = uW PLL unlocked error

Bit 2 = Ref unlocked error

Bit 3 = ALC High unleveled error

Bit 4 = ALC Low unleveled error

Bit 5-15 = Not Used

Return Value

This return value always returns VI_SUCCESS.
