May 2010 [Test & Measurement] Sizing Up RF Switch Systems Microwave test systems often include one or more RF/microwave switches to allow automated testing as well as measurements on multiple devices under test (DUTs). When configuring a highfrequency switching system for test applications, it is important to understand the type of switch and multiplexer options available as well as the critical switch specifications when choosing a switch. Switch systems for RF and microwave applications ... January 2005 [Test & Measurement] Compare Analyzers And Meters For Power Tests Power meters are often considered for mobile-telephone production testing, because they can quickly measure peak power, average power, and peak-to-average ratio. But an RF power meter has certain deficiencies that hinder accurate wireless handset testing. For example, an RF power meter cannot identify where in the frequency spectrum a device is transmitting its power. Because of this, a handset may pass a power test with a power meter, but transmit at the wrong frequency or suffer... |
