The Agilent/Keysight 3577A is a programmable network analyzer covering 5 Hz to 200 MHz with 100 dB dynamic range. It performs magnitude, phase, insertion loss, return loss, reflection coefficient, impedance, gain compression, and group delay measurements. The instrument delivers ±0.02 dB dynamic accuracy with resolution to 0.001 dB in magnitude, 0.005° in phase, and 1 ps in time-domain analysis.
