National Instruments  introduces a new range of high performance PXI digitizers with high bandwidth to complement the rapidly expanding suite of performance instrumentation available in PXI.  

Co-developed with Tektronix, the world’s leading manufacturer of oscilloscopes, the NI PXIe-5186 digitizers employs Tektronix, Enabling Technology to achieve up to 5 GHz bandwidth and 12.5 GS/s sample rates.  

National Instruments has also introduced the NI PXIe-5185 digitizers, which deliver 3 GHz bandwidth along with 12.5 GS/s sample rate.  

Both digitizers are part of the National Instruments PXI-based hardware and software platform, which provides optimised performance for automated test applications.  

The digitizers are ideal for applications such as automated production tests, semiconductor ATE and high-energy physics measurement systems.

Key features of the PXI digitizers: 

  • Proprietary Tektronix performance oscilloscope ASICs provide high-speed signal acquisition with low noise and high linearity
  • Based on the highly-reliable IBM 7HP SiGe process
  • Superior signal fidelity delivered by Tektronix, Enabling Technology with low sampling jitter
  • Very low 500 fs RMS integrated jitter results in 5.5 effective number of bits (ENOB) at 5 GHz
  • NI proprietary technology delivers high-data throughput for faster test execution and precision multimodule timing and synchronisation for building high-channel-count, integrated test systems
  • Designed for the 3U PXI Express platform
  • Streams at rates as fast as 700 MB/s and synchronises channels on multiple modules to within160 ps resolution
  • Works with NI LabVIEW graphical design software for instrument control and automation plus NI LabWindows/CVI ANSI C and Microsoft Visual Studio .NET
  • Programmed with NI-SCOPE instrument driver or the new LabVIEW Jitter Analysis Toolkit

Dr. James Truchard, President, CEO and Co-founder of National Instruments comments that the new product combines the strengths of both companies with Tektronix contributing high-speed digitization and NI offering software-defined instrumentation.

According to Kevin Ilcisin, Chief Technology Officer for Tektronix, customers benefit from their industry-leading signal acquisition technology complemented by world-class instrument control via National Instruments, the pioneer of the PXI standard and the world leader in instrument automation.
