The 8719D is a Microwave Vector Network Analyzer for laboratory or production measurements of reflection and transmission parameters.

It integrates a high resolution synthesized RF source, an S-parameter test set, and a four-channel three-input receiver (four-input receiver, Option 400) to measure and display magnitude, 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.

It has measurement functions selection with front panel keys and softkey menus. Simultaneous viewing of all four S-parameters by enabling the auxiliary channels 3 and 4.

Performance improvement and flexibility through trace math, data averaging, trace smoothing, electrical delay, and accuracy enhancement.

Accuracy enhancement methods that range from normalizing data to complete one or two port vector error correction with up to 1601 measurement points, and TRL*/LRM*. (Vector error correction reduces the effects of system directivity, frequency response, source and load match, and crosstalk.)

Test system automation with the addition of an external controller. This allows all of the analyzer measurement capabilities to be programmed over the Hewlett-Packard Interface Bus (HP-IB).
