Hi Joe, I think it is quite limited in the actual phase noise floor you can achieve at carriers <1GHz. A good OCXO will far out-perform this utility due to the noise-floor limits of the 8560 series. To give you an idea, you get about ~90dBc/Hz up to 100Hz offset or so, then 120 - 130dBc above 10KHz. Not spectacular for time-nuts purposes. It is useful for PLL design and spur analysis though. I don't have to use any noise source for my version running on an 8561E. bye, Said In a message dated 8/17/2009 21:50:55 Pacific Daylight Time, [email protected] writes:
Date: Mon, 17 Aug 2009 09:22:18 -0500 Can anyone provide any information on the usefulness of the Phase Noise Utility program (85671A) for the HP 8560 series Spectrum Analyzers? Joe I have used that several years ago. It worked well enough, requires a noise source in addition to the spec an. Time taken is inversely proportional to the bandwidth selected, and don't expect to take any readings quickly. My summary: nice, given the round about way this is.
