The HP/Agilent 8714ET is a 3 GHz RF vector network analyzer engineered for high-volume manufacturing and production testing. This compact, integrated instrument combines a synthesized source, transmission/reflection test set, multi-mode receivers, and display to measure S-parameters, impedance, gain, return loss, and isolation across RF components including filters, amplifiers, antennas, cables, and mixers. Available in both 50-ohm and 75-ohm configurations.
