Why use a USB Attenuator?
In RF test labs, programmable attenuators and RF switches are a basic building block of performance testing. Programmable attenuators are used in fading, handover, and rate vs range testing. Among other things, RF switches are used in signal routing, component bypassing and switched filter banks. To fill this need, JFW offers an expansive selection of Programmable Attenuator Assemblies and RF Switch Assemblies in 19″ rack or benchtop enclosures. These boxes typically include Ethernet and RS-232 control. While appropriate for medium to large testing environments, a USB Attenuator or USB RF Switch is often a better solution for smaller test setups. Lower cost and smaller size of the USB device are especially relevant.
