Wait for RQS gives error -1073807313 after upgrade to WinXP

Wait for RQS gives error -1073807313 after upgrade to WinXP

‎11-03-2003 08:17 AM

Since upgrading our lab machine to WinXP from WinNT4 one of my instrument dirvers which uses the 'VISA wait for RQS' function returns the error -1073807313 (Hex 0xBFFF002F) You must be enabled for events of the specified type in order to receive them.

I am enabling the OPC bit in the Event Status Register and Event Summary bit in the Status Register. (*CLS;*ESE 1;*SRE 32; SENS1:EYE:TCEN ON; *OPC;). In WinNT4 this worked like a charm. Now in WinXP I get an error.

Any ideas?

This is referring to the VISA software, not to the device. You must first call VISA Enable Event with event type Service Request. You may just be missing a call to some other instrument driver function that does this for you.
