The Agilent 87104D multiport switch improves signal accuracy in RF and microwave signal routing and testing applications. This high performance electromechanical switch provides unmatched isolation and a 0.03 dB insertion loss repeatability, which is warranted for the 5-million life cycle of the switch. The 87104D’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 Agilent's rigorous design and tight manufacturing specifications.
