Yes, You have removed the reference from the warmup but the input circuits still need time to reach thermal equilibrium for most accurate results

If the counter uses the external reference to lock the internal one then it is better to wait until the internal one is stable, maybe the counter has a standby mode where it appears powered off but the internal reference is active (usually an ovenized reference). For the best performance (stability of trigger levels, input amplifiers and so on) it is better to warmup the whole counter always. > On Thu, Feb 8, 2018 at 8:33 AM, Chris Wilson <[email protected]> wrote: > > > 08/02/2018 07:31 > > Does a frequency counter connected to a permanently running (Trimble > Thunderbolt) GPS > disciplined frequency standard need to warm up after switch on before > readings settle? > Just curious, thanks. > > -- > Best Regards, > Chris Wilson. > mailto: [email protected] > > _______________________________________________ > 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. _______________________________________________ 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. _______________________________________________ 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.
