Sure, send me the GPIB .PDF, either via Didier's site, ftp.ko4bb.com, user manuals, password manuals) or via my GMail account at [EMAIL PROTECTED] It looks like a great spectrum analyzer considering the prices they seem to fetch on eBay. Should be a nice upgrade from the 8596E, all right. The only requirement is that I need to be able to count on you to test the code *carefully*. This can be a trying process, because PN.EXE has to carry out a lot of interaction with the spectrum analyzer, and it's tough to write code for one that isn't sitting on my workbench. The ideal scenario is one where I have a remote-desktop account on a WinXP box at your end, with an NI or Prologix board connected to the R3267. That takes you out of my edit-compile-test loop. :) That's not vital, but it really helps speed things up. -- john, KE5FX _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
