The Keysight/Agilent/HP 3577A Network Analyzer paired with the 35677B S-Parameter Test Set delivers precision impedance and S-parameter measurements from 5 Hz to 200 MHz. This dual-unit system excels in design and production environments, characterizing two-port devices with high speed and accuracy. The 3577A employs individual precision analog receivers for each input, eliminating signal multiplexing to preserve measurement integrity. Both units are fully programmable via HP-IB (IEEE 488), enabling automated test sequences and seamless integration into larger measurement systems.
