Grab the latest release from www.miles.io/timelab/readme.htm if you like -- it will acquire from the TSC 5125A for as many hours/days as the TSC's Ethernet connection will stay up. (Which sometimes isn't very long.) TimeLab generates its frequency-difference plot from the acquired phase data, so it will give you various display and filtering options that the 5125A itself will not. -- john Miles Design LLC _______________________________________________ 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.
