Agilent/Keysight 8752C

The Agilent/Keysight 8752C is a vector network analyzer integrating synthesized source, test set, and receiver into a single compact unit for RF component and network characterization. It delivers accurate S-parameter measurements across 300 kHz to 1.3 GHz (expandable to 3 GHz or 6 GHz), with dual independent channels for simultaneous transmission and reflection analysis. The instrument supports full two-port calibration with integrated error correction, measuring reflection coefficient, return loss, phase, gain, isolation, group delay, and linear phase deviation across multiple display formats including Smith chart, polar, and time-domain representations.
