Trouble with addresses between a PCI-GPIB board and an HP 8648C signal generator.

[Shepherd]

I am using LabView 6 on a Macintosh G3 and the VIs I write work fine, except that they keep changing the address of the GPIB board to 19 instead of calling on the instrument at address 19.

If I start-up LabView and run one of my VI's, I get the error "-1073807302" and the possible reason is listed as "VISA: (Hex 0xBFFF003A) Unable to start operation because setup is invalid (due to attributes being set in an inconsistent state)."

Then, I can go into IBIC and reset the board address, which somehow gets set to 19, back to GPIB0 and run my VI again. After that, things work properly.

I would be much obliged if anyone could help me figure out how to make it work right
the first time.

Thanks

Hello-

Have you verified that GPIB0 is not set to primary address (PAD)=19. Is it possible to change the PAD of the device.

Also, have you seen the LabVIEW Instrument Driver for the 8648A? It's at http://zone.ni.com/idnet97.nsf/browse/ and may help you get started in writing code for this device.
