HP/Agilent 8720D Microwave Vector Network Analyzer, 50 MHz to 20 GHz

The HP/Agilent 8720D is a high performance vector network analyzer for laboratory or production measurements of reflection and transmission parameters. It integrates a hish resolution synthesized RF source, an S-Parameter test set, and a four channel, three input (four input receiver, Option 400) to measure and display magnatude, phase and group delay responses of active and passive RF networks.
Two independent primary channels, two auxiliary channels, and a large screen color display show the measured results of one or all channels, in cartesian or polar/Smith chart formats.
