The Agilent 85047A S-Parameter Test Set is a two-port measurement instrument that extends network analyzer capability for full S-parameter characterization of RF and microwave components. Designed for filters, amplifiers, antennas, and similar devices, it delivers reflection and transmission coefficient data with integrated error correction across all four S-parameters. Solid-state switching architecture eliminates mechanical relays, enabling continuous parameter updates, 160 millisecond faster trace acquisition on 101+ point sweeps, and simultaneous dual S-parameter monitoring. The test set operates across multiple frequency spans depending on configuration—300 kHz to 6 GHz with compatible analyzers, 3 MHz to 6 GHz with frequency doubler engaged, or 300 kHz to 3 GHz with doubler disengaged. Output impedance is 50 Ohms with 15 dBm test port power and insertion loss under 5 dB. Programmable step attenuators provide dynamic range control. Engineered for R&D and production environments where reliability, measurement speed, and accuracy are critical.
