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.
