How do I monitor test station GPIB activity using an external roll around PC with a PCI-GPIB card installed?

[reboot1]

I need to monitor GPIB activity on an old HP-1000 test station.  I have an external roll around PC / Win 2000 with a PCI-GPIB card installed.  For some reason I cant get NI-Spy to capture bus activity.  Is it possible to use the PCI-GPIB card and NI-Spy on the external PC to capture GPIB activity on the old station?

Thanks.

I think NI-Spy will only monitor traffic generated from/to the NI board you have. You probably need a bus analyzer board.

Is it possible to configure the PCI-GPIB as a listener using CVI or LabView?

reboot1,

It would be possible to add another PCI-GPIB as a listener if you modified the GPIB controller in charge code.  You can always add the extra PCI-GPIB primary address as a listener through all interactions (each read/write would need to be modified to add this new address as a listener).  This way, as long as there is code telling the extra PCI-GPIB to constantly read from the bus, you will get all data transferred.  However, this is fairly complicated and should not be attempted if you do not have full control over the controller in charge program.
