MANHASSET, NY -- National Instruments has released what the company claims is the industry's highest bandwidth PXI digitizer, co-developed with Tektronix.
The NI PXIe-5186 digitizer uses Tektronix application specific ICs to achieve up to 5 GHz bandwidth and 12.5 GSamples/s rates.
The company also announced the NI PXIe-5185, which delivers 3 GHz bandwidth along with 12.5 GSamples/s rate, also with Tek's ASICs.
"We are excited about our work with Tektronix to jointly develop a product that combines the strengths of both companies: Tektronix for high-speed digitization and NI for software-defined instrumentation," said James Truchard, president, CEO and cofounder of National Instruments, in a statement.
The proprietary Tektronix ASICs are based on the IBM 7HP SiGe process.
Tektronix's enabling technology ensures low sampling jitter of the digitizers. The very low 500 fs rms integrated jitter of the digitizers results in a 5.5 effective number of bits (ENOB) at 5 GHz. The technology is an ongoing collaboration between the two companies.
Designed for the 3U PXI Express platform, the digitizers can stream at rates as fast as 700 MBytes/s and synchronize channels on multiple modules to within 160 ps resolution.
The digitizers work with NI LabView graphical design software for instrument control and automation, the NI LabWindows/CVI ANSI C software development environment and Microsoft Visual Studio .Net development tools for a wide range of programming options.
Engineers can program the digitizers using the NI-Scope instrument driver or the new LabView Jitter Analysis Toolkit, which offers a library of functions optimized for high-throughput, jitter, eye diagram and phase noise measurements.
Both companies are leaders in measurement instruments. The collaboration seems to be just the right timing. It would be neat to see a few case studies that show applications of the fast PXI digitizers in action.
