The HP 3577A Audio/IF/RF Network Analyzer covers a frequency range of 5 Hz to 200 MHz and offers 100 dB dynamic range, high resolution, and selectable input impedances for both 50 Ω and 1 MΩ configurations. The manual describes measurement functions such as transfer‑function, magnitude/phase, insertion loss, gain compression, and phase‑distortion parameters, plus built‑in autoscale, marker, and direct‑plot capabilities.
Programming over the HP‑IB interface, calibration procedures, vector‑math functions, and detailed accessory information are also included. Technical specifications, operating conditions, and ordering details are provided for service and integration purposes.
