Agilent/Keysight 70301A – Microwave Tracking Generator (for 70000 series, up to 18 GHz)

The Agilent/Keysight 70301A is a microwave tracking generator module that adds stimulus-response measurement capability to Keysight 70000 series spectrum analyzers. Operating from 2.7 GHz to 18 GHz, it enables simultaneous signal generation and analysis for precise characterization of component gain, frequency response, isolation, and return loss. The module integrates directly into the 70000 series modular measurement system, delivering dynamic range exceeding 130 dB when paired with compatible analyzers.
