Damn. I merely hit reply and generated some embedded HTML. My apologies for the QRM. What I tried to post to Jim Lux was: >> I assume you've got the 8640s locked to a common source (or each other). Highly unlikely -- the 8640s are free-running oscillators with excellent short-term phase noise. Signal is derived from a cavity oscillator. The have a rudimentary frequency stabilizer which can lock the last digit of the frequency from an internal counter, but the frequency can wander +/- 1/2 digit. Hence, the two-tone measurement is not made with coherent oscillators. 73, Tom _______________________________________________ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/
