The Keysight (Agilent) 33366K is a Single Pole, Six Throw (SP6T) electromechanical RF coaxial switch engineered for high-performance signal routing in test and measurement systems. Operating from DC to 18 GHz with exceptional repeatability and isolation characteristics, this switch delivers the reliability required for automated test equipment (ATE) and complex signal routing matrices. The 33366K employs a wiping-action contact mechanism that continuously cleans the contact area, ensuring consistent insertion loss repeatability throughout its operational life and minimizing measurement uncertainty in demanding RF and microwave applications.
