Hi Steve, GPIB / HPIB FAQ sounds like a good idea .. If you're going to include HPIB bus analyzers in your FAQ it would be worth looking at the National Instruments PCI-GPIB+ card. This card can be configured as a bus analyser that captures all HPIB messages (control, data and status) onto a controller PC with the size of the log-file limited only by available disk space. I've found it to be a lot more useful than the more commonly available HP 59401A analyser. If you need any further info on this card for your FAQ then please feel free to drop me an e-mail. Cheers Peter
