Agilent / Keysight 87510A Gain-Phase Analyzer

The Agilent/Keysight 87510A Gain-Phase Analyzer is a precision instrument for measuring gain and phase characteristics of electronic components and systems from 100 kHz to 300 MHz. It delivers vector transmission measurements with 1 mHz frequency resolution and dynamic accuracy of ±0.05 dB and ±0.3°. The analyzer supports multiple measurement modes (A/R, A, R) and features automatic parameter-extraction commands for filter and resonator characterization.
