Hi, all The question of phase shifts in cables pops up every now and then on this list - I stumbled across a good table of measured phase shifts with temperature in different cable types in this paper: http://www.ira.inaf.it/eratec/gothenburg/presentations/ERATEC_2014_PresentationWSchaefer.pdf that I though would be of interest to others.
A quick summary given below, see pdf for full details. Lots of other interesting stuff in there also. Values in ppm/K, for 10 Mhz except when otherwise stated. (The paper gives values for 5, 10 and 100Mhz) Huber-Suhner Multiflex 141: -6 RG-223: -131.9 Semiflex Cable: -11.5 Huber-Suhner: -8.6 Times Microwave LMR-240: -3.4 Times Microwave SFT-205: 7.7 Meggitt 2T693 SiO2: 30.6 Andrew FSJ-1 (@5Mhz): 25 Andrew FSJ-4 (@5Mhz): 10 Andrew LDF-1P-50-42: 2.8 Andrew LDF4-50A: 4.7 Times Microwave TF4FLEX (@100Mhz):6.4 Phasetrack PT210 (@100Mhz): 2 Ole _______________________________________________ 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.
