The Keysight (formerly Agilent/HP) 8753D is a highly regarded RF Vector Network Analyzer operating from 30 kHz to 3 GHz, with an option to extend its range to 6 GHz. It features a built-in S-parameter test set and provides up to 110 dB of dynamic range, enabling complete forward and reverse characterization of components with a single connection. Incorporating a suite of productivity features including test sequencing, pass/fail limit testing, and optional time domain and harmonic capabilities, the 8753D is a versatile workhorse for RF component testing and mixer characterization.
