The HP/Agilent 8720 series network analyzers (models A through ES) are integrated vector measurement instruments for RF and microwave characterization. Each unit combines a synthesized source, tuned receiver, and switching S-parameter test set in a single platform. Frequency coverage spans 50 MHz to 20 GHz depending on model, with dynamic range up to 105 dB and measurement rates as fast as 1 ms/point. These analyzers deliver accurate two-port S-parameter measurements for component evaluation, manufacturing validation, and R&D applications.
