I've done a few quick tests and the performance seems to be quite good, but I suspect they're not designed for lab work; I think Spectracom is more used in broadcasting and similar applications. I'll try to set up a test with the 5370B and see what differences I can discern. I may also get a chance to do a phase noise test with a 3048 system.
