Is there as way to set the Status Byte, other than ibrsv?

[BEG]

I am trying to emulate an instrument that sets the status byte to 64, but does not assert the SRQ line. Using ibrsv asserts SRQ, which seems to cause problems with my legacy test system. I am using LabWindows/CVI under Windows NT and a PXI-GPIB.

Hi,

According to the IEEE 488.2 standard, bit 6 of the status byte register (value 64 or 0x40 hex) indicates that the instrument is requesting service. Usually setting this bit will automatically assert the SRQ line. The NI-488.2 does not provide a function that just set this bit without the interface asserting the service request line.

If your instrument never asserts the SRQ line, you could create a custom cable that does not have that line connected. Just a thought.
