My scope (Keysight MSOX3104, so 1 GHz) is rated at ±1.6 ppm (after a 30 minute warmup and ±10C from calibration temperature). The 3000 series and below don't have 10 MHz external reference inputs; I know the 4000 series does. /gp _______________________________________________ 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.
