The multiport switch terminated with the Keysight 87206C provides the lifespan and reliability required for automated test and measurement, signal monitoring and routing applications. Innovative design and careful process control have created the Keysight 87206C, which meets the requirements for highly reproducible switching elements in test devices and switching interfaces. The Keysight 87206C is designed for more than 10 million cycles. The exceptional repeatability of the insertion loss of 0.03 dB is guaranteed for 5 million cycles at 25 ° C. This reduces the causes of random errors in the measurement path and improves the measurement uncertainty. The lifespan of switches is a critical issue in production test systems, satellite and antenna monitoring systems, and test instruments. The longevity of this switch increases system availability and lowers operating costs by reducing switch calibration cycles and maintenance.
