With 1000 feet of cable might be an issue for fine stuff. a few nano seconds each way over temperature might not matter for his project... I forget it is not a microwave RF VNA application. Easy to resolve anyway with a difference balance term somewhere. g On 7/07/2019 11:23 AM, Hal Murray wrote: >> coax cables are in general NOT PHASE STABLE with temperature, either. > Is twisted pair any better? > > > _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
