The pre-owned Agilent 8720D combines a fast synthesized source, vector receiver, and solid-state S-parameter test set to provide complete 2-port measurements from 50 MHz to 20 GHz. With up to 105 dB dynamic range and rapid sweep hardware, it resolves small magnitude and phase variations in filters, amplifiers, mixers, and on-wafer devices while keeping test times low. Integrated error-correction, time-domain analysis, and SCPI automation preserve laboratory accuracy in a single-box solution.
Purchasing refurbished slashes capital outlay and delivery lead-time; units can ship ISO-17025–calibrated with current firmware, delivering proven Agilent reliability at a fraction of new-instrument cost.
