I noticed today that Symmetricom has upgraded it's venerable 1000B. The 5MHz "C" model has a premium version with a rated -130dB @ 1Hz offset. I think that is the best rated spec I have seen. Noise floor is a lackluster 160dB @ 100KHz. Sounds like a BVA. The data sheet is at: http://www.symmetricom.com/resources/download-library/documents/datasheets/1000c/
