Keysight Technologies Coaxial Electromechanical Switches :How Operating Life and Repeatability of Keysight’s Electromechanical Switches Minimize System Uncertainty Application Note
■Introduction
▲Keysight Technologies, Inc. is the global leading designer and manufacturer of coaxial electromechanical (EM) switches, with a long history and proven track record for high performance, quality and reliability. Coaxial EM switches provide the reliability and performance required by automated test systems used in the aerospace and defense and wireless communication industries for signal monitoring and routing purposes. One of the most common applications of coaxial EM switches is mobile handset testing in the wireless communication industry.
▲According to a research study1, global mobile handset shipment is on track to reach one billion units shipped in 2006, representing a 22.5% growth over 2005. This impressive growth rate places high emphasis on the reliability and performance of automated test systems (ATS) used for mobile phone testing, of which the EM switch is a major component. Two of the most important considerations when selecting an EM Switch are operating life and repeatability.
▲This application note describes:
◆The operating life of EM switches, the jumper contact mechanism of conventional EM switches, and the Keysight contact mechanism with its wiping-action technology
◆Finally, the effect of repeatability on measurement uncertainty is discussed.
