TheHP 8720D is a high performance vector
network analyzer for laboratoryor production measurements of reflection and transmission parameters. Itintegrates a high resolution synthesized RF source, an S-parameter testset, and a four-channel three-input receiver to measure and displaymagnitude, phase, and group delay responses of active and passive RFnetworks.
Two independent primary channels, two auxiliarychannels, and a large screen color display show the measured results ofone or all channels, in Cartesian or polar/Smith chart formats.
