The Keysight (Agilent/HP) 8563E is a high-performance portable microwave spectrum analyzer providing continuous frequency coverage from 9 kHz to 26.5 GHz (or 30 Hz to 26.5 GHz with Option 006). Built to MIL-T-28800 specifications for harsh environments, it combines synthesized tuning, precision timebase, and wide dynamic range into a rugged form factor. The unit features fast digital resolution bandwidths down to 1 Hz, preselection from 2.75 GHz upwards, and built-in standard measurement functions including adjacent channel power and time-gated analysis.
