The Agilent/Keysight 85685A Tracking Generator is an essential tool for comprehensive network analysis when paired with compatible spectrum analyzers. Its key specifications include a broad frequency coverage, ensuring compatibility with a wide range of devices under test. The flatness specification guarantees minimal amplitude variation across the frequency range, leading to more reliable measurements. The output level control allows users to optimize the signal strength for different measurement scenarios, preventing damage to sensitive devices and maximizing signal-to-noise ratio.
