Repair and Service Evaluation – HP/Agilent 8719C, 8719D, 8719ES, 8719ET Analyzers

The HP/Agilent 8719C, 8719D, 8719ES, and 8719ET are vector network analyzers designed for RF and microwave component characterization across 50 MHz to 13.5 GHz, with extended-range models reaching 20 GHz or 40 GHz. These instruments integrate a synthesized source, S-parameter test set, and tuned vector receiver to measure magnitude, phase, and group delay with dynamic range up to 105 dB and frequency accuracy of 10 ppm. Built-in error correction supports full two-port, adapter-removal, and TRL calibration, while optional time-domain and high-power capabilities extend measurement scope to fault location and high-power device testing.
