NI Announces 11 PXI RF Switches For Video And Communications Test
All 11 modules offer low insertion loss (less than 2.1 dB at specified bandwidth) and voltage-standing wave ratio (less than 1.75 at bandwidth) to minimize power loss, voltage attenuation, and signal reflections. Alternative PXI RF switches available on the market have up to 3 dB of insertion loss and voltage-standing wave ratio greater than 1.8 at their bandwidth frequencies. The new modules also offer relay count tracking. With this feature, engineers can keep track of relay closures on board the hardware to estimate the lifetime of individual relays on the module and avoid unexpected system downtime.
Engineers can program all of the new switches using the full-featured NI-SWITCH driver software for basic relay operations in common development environments such as the NI LabVIEW graphical development environment, LabWindows/CVI for ANSI C development and Microsoft Visual Basic/C++. For additional assistance in configuring, programming and managing high-channel-count switching systems, NI Switch Executive software offers an intelligent switch management and visual routing environment. Once they have configured and programmed their switch networks, engineers can deploy them using NI TestStand, a ready-to-run test management environment and framework designed to simplify the automation of test and validation systems.
