Agilent/Keysight 8712ES

The Agilent/Keysight 8712ES is an RF network analyzer engineered for S-parameter and impedance measurements from 300 kHz to 1.3 GHz. The instrument integrates a two-port vector-error corrected test set with dual independent channels, delivering 100 dB dynamic range and 40 ms sweep times. It operates across 50-ohm and 75-ohm system impedances and supports full two-port vector-error correction for calibration.
