The Keysight L7204B unterminated multiport switch improves accuracy in signal RF and microwave signal routing and testing applications. This electromechanical switch provides unmatched isolation and a 0.03 dB insertion loss repeatability, which is warranted for the 2 million cycles of the switch. The L7204B’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 uptime. Keysight's rigorous design and tight manufacturing specifications make the highly repeatable switching capability possible.

Ideal for manufacturing test engineers working on system integration, the L7204B unterminated multiport switch provides an economically priced, reliable solution for signal monitoring and routing applications.
