Hello, We use an agilent E4419B +/- 0.02dB log or 0.5% linear with an E4412A Mount with an uncertainty of 1.3%.
See http://cp.literature.agilent.com/litweb/pdf/5965-6382E.pdf for uncertainty.

For now lets assume I am trying to measure a 80dBuV sine wave between 30MHz to 1GHz from a 50 ohm source and other signal componets not at the intended frequency is at least 80dB down. The standard choices are spectrum analyzer with ~2dB uncertainty, receiver with ~1dB uncertainty or watt meter with ~0.5dB uncertainty. All uncertainty's are assumed to be with an expanded uncertainty of K=2. Does anyone know of a method or device that can do better than the watt meter? Let's limit the discussion to a device that costs <$20K.
