Thanks Tom, but the only RF genny I have is a pair of HP 8568B and a HP 8567A I think it is. The fan runs all the time on the 8567A so it mainly stays unplugged..
The only thing I have that can go that high is an 8350B Sweeper with a 83522A plugin (0.01-2.4 GHz). Can I utilise the sweeper somehow? --marki -----Original Message----- From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com] On Behalf Of Tom Miller Sent: Thursday, 25 July 2013 4:58 PM To: Discussion of precise time and frequency measurement Subject: Re: [time-nuts] testing L1 antenna You might generate a CW RF test signal at a level that allows easy detection on the SA. Maybe into a simple dipole antenna. A second dipole test antenna could establish a reference that you could relate the GPS antenna gain to. Tom ----- Original Message ----- From: "Mark C.

As a test procedure, all I can come up with is a power-injector connected to the feed line, the feed line connected to a DC block on the input of a 8566A SA. Then connect a known good antenna and compare the DUT. Note: I haven't tried this yet, still thinking about it :) Has anyone got a proven method to check a GPS timing antenna for reliable operation? --marki _______________________________________________ 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. _______________________________________________ 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. _______________________________________________ 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.
