The HP Agilent 8566A is a high-performance spectrum analyzer for bench and ATE system use. The HP 8566A operates from 100 Hz to 22 GHz and up to 32.5 GHz with external mixers.

The exceptional frequency stability of the Agilent 8566A make measurements with a 10 Hz resolution bandwidth easy. 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.

Typical 8566A applications include EMC testing, broadband signal surveillance, and component stimulus-response testing.
