What GPIB card do you have? If it shows up in Measurement and Automation Explorer (MAX) as PCI-GPIB and not PCI-GPIB+, the GPIB Analyzer will not work. Only GPIB+ boards support the GPIB Analyzer. If you have a GPIB+ board, has the analyzer worked before? Have you changed anything since the last time it functioned correctly for you?
