HP / Agilent 8722A 40 GHz Microwave Network Analyzer

The HP/Agilent 8722A is a 40 GHz microwave network analyzer that integrates a synthesized source, tuned receiver, and S-parameter test set into a single instrument. Operating from 50 MHz to 40 GHz, it delivers the frequency resolution, measurement accuracy, and dynamic range required for RF and microwave component characterization in research, development, and production environments.

Key Features

Vector accuracy enhancement and error correction

Two independent display channels; four on 8722ES

Two internal bias tees for transistor biasing

Power meter calibration capability

Limit testing for Pass/Fail evaluation

Internal test sequencing and automation

Direct save/recall to external disk drive via 3.5" floppy (DOS and LIF formats)

Fully programmable via HP-IB from external computer

3.5 mm test port connectors; 2.4 mm adapters included

Measurement Capabilities S-parameter analysis, insertion loss, return loss, transmission gain/loss, and impedance measurements across the full 50 MHz to 40 GHz band. Measurement accuracy varies by frequency; 20–40 GHz band (8722ES) specifies directivity to 38 dB, source match to 33 dB, and load match to 38 dB.

Compatibility & Integration Serial and parallel interfaces support modern printers and plotters. Synthesized source, switching test set, and tuned receiver operate as a single integrated unit, eliminating the need for external components in most measurement scenarios.
