High performance and simple operation are combined with unique microprocessor-controlled capabilities in the 8569B Microwave Spectrum Analyzer. Excellent sensitivity and internal preselection assure the wide, spurious-free measurement range necessary for production applications, while the digital display and couples controls speed measurement routines.

The internal frequency range of 10MHz to 22GHz is extended using external mixers: to 40GHz in two bands (optional); to 71GHz with 11971 series mixers (sold separately); and to 115GHz with commercially available mixers. For semi-automatic operation, connect a desktop computer to the unit via HP-IB to allow access to the displayed trace data and the control settings necessary to analyze or record measurements, or display operator messages and prompts on the CRT. Direct, hard copy output to a digital plotter is possible with the need of a controller or any programming.
