Agilent/Keysight 8712ET

The Agilent/Keysight 8712ET is a vector network analyzer engineered for manufacturing and R&D testing of RF components from 300 kHz to 1.3 GHz. The instrument combines a synthesized RF source, transmission/reflection test set, three independent multi-mode receivers, and integrated display in a single chassis. Available in 50-ohm and 75-ohm configurations, it delivers dynamic range exceeding 100 dB in narrowband-detection mode and employs vector-error-correction techniques for measurement accuracy.
