Can anyone provide any information on the usefulness of the Phase Noise Utility program (85671A) for the HP 8560 series Spectrum Analyzers?

Some have commercial phase noise measurement systems like Symmetricoms 5115A, 5120A. 5125A. Some have older HP phase noise measurement systems like the 3048A etc. The rest of us have to build our own systems based around sound cards or surplus spectrum analysers together with the necessary mixers, low noise amplifiers etc. Unless your sources are very noisy you wont be able to measure their phase noise with just a selective voltmeter or even an RF spectrum analyser. If you cant build it, then you need to acquire something like the HP3048 or the NIST phase noise measurement box currently on ebay.(Item: 260423038423) Bruce _______________________________________________ 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. _______________________________________________ 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.
