The 8566B is a high-performance spectrum analyzer for bench and ATE system use. The 8566B has a frequency range from 100 Hz to 22 GHz that can be extended to 325 GHz using external mixers.
The exceptional frequency stability of the 8566B makes it possible to make measurements with a 10 Hz resolution bandwidth. This narrow resolution bandwidth yields sensitivities to -135 dBm. Excellent frequency stability, sensitivity, and frequency-reference accuracy combine to allow very accurate measurement of small signals in the presence of large ones. This spectrum analyzer fits into many applications, such as EMC testing, broadband signal surveillance, and component stimulus-response testing.
