The Keysight L7106A multiport switch improves accuracy in signal RF and microwave signal routing and testing applications. This economically-priced, electro-mechanical switch provides unmatched isolation and a 0.03 dB insertion loss repeatability, which is warranted for the 2-million life cycle of the switch.
The L7106A’s low insertion loss repeatability reduces sources of random errors in the measurement path, which improves measurement accuracy. The repeatability and reliability of this switch guarantee measurement accuracy and can cut the cost of ownership by reducing calibration cycles and increasing test system up time. Highly repeatable switching capability is made possible through Keysight's rigorous design and tight manufacturing specifications.
