Hi John etc, I've been reading all the posts and greatly appreciate the help. I may end up getting a 11729C, these seem to be reasonably priced. I've tried two ways to calibrate my setup: one was to detune the OCXO's by >20Hz, and measure the resulting beat frequency level. Another was to use our FireFox signal generator to add a 10.0001MHz signal -30dB below the carrier into the DUT output using a power combiner, and measuring the resulting 100Hz spur. Both methods result in output spurs that are within <2dB of expected. I will try the hints from everyone, thanks, Said **************Start the year off right. Easy ways to stay in shape. http://body.aol.com/fitness/winter-exercise?NCID=aolcmp00300000002489 _______________________________________________ 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.
