New NI PXI Switch Features Solid-State Architecture to Increase RF Test System Life and Speed for High-Volume Applications


AUSTIN, Texas April 24, 2012

News Highlights

  • NI PXI/PXIe-2543
  • The switch increases test throughput and provides long-term measurement repeatability in many high-volume RF production test applications, including semiconductor and mobile device testing.
  • The switch module further extends NI’s broad portfolio of PXI modular instruments to address the latest RF engineering challenges.


National Instruments (Nasdaq: NATI) today introduced the new NI PXI/PXIe-2543 solid-state RF multiplexer, which gives test engineers a long-lasting, high-performance solution to optimize the routing of RF signals up to 6.6 GHz. Its solid-state architecture facilitates faster switching and more repeatable measurements than traditional electromechanical switching solutions.
