HP 70428A Microwave Source Module

If four slots are available in your MMS system, microwave source capability can be added with the HP 70428A microwave source module. The HP 70428A microwave source module makes an excellent substitute LO for your radar system, phase noise measurement system, or test source for microwave receiver testing. It provides the lowest AM phase noise of any commercially available microwave source and provides up to +16 dBm of output power. The HP 70428A requires either the HP 70001A mainframe or the HP 70004A display.

[ Features ]
