I hate to "Osborne" myself since it's still in a pretty incomplete state of development, but I'm working on a new GPIB app that does one-stop shopping for time-interval measurements. It will run on the 5370A/B first. If you were to use this app to make the measurements you mentioned, you'd most likely feed the 1-pps output of your reference source to the Start channel on the 5370, and feed 10 MHz from the unit under test to the Stop channel. The program will then receive one result per second from the counter and draw you an ADEV graph, at which point you can load and display previously-saved files for direct comparison. More later on that, just giving you a heads-up so you don't do any R&D work that you don't actually have to. One way you can accomplish the same thing now is to run the 5370b.exe console app from my package, pipe the output to a file, and read it with Ulrich's PLOTTER utility (which is a separate app from EZGPIB). That will save you from having to do any scripting work. -- john, KE5FX _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
