Agilent/Keysight 11857F

The Keysight 11857F is a 75-ohm Type-F test port cable set engineered for RF and microwave network analyzer measurements. This two-cable kit provides the necessary calibration standards to minimize systematic measurement errors when working with Type-F connector devices. Each cable measures 24 inches (61 cm) in length and maintains precise electrical performance across the measurement range.
