BAE Systems, National Instruments (NI) and Phase Matrix Inc. (PMI) announced a joint initiative to develop a PXI Express-based synthetic instrument for military and commercial RF and microwave applications. PMI is currently developing a 100KHz to 26.5GHz family of down-converter modules in a 3U PXI Express-compatible format to support PXI RF and microwave applications.

BAE plans to build a next-generation synthetic instrument based on the new down-converter module family, using NI's PXI Express chassis, controllers and intermediate frequency digitizer modules as well as NI's LabVIEW graphical development software for host and FPGA-based signal processing.

"After a long history of designing, developing and manufacturing VXI-based microwave instruments, we are using our expertise to take PXI Express synthetic instrumentation into a new era of powerful RF and microwave test and measurement systems," said Pete Pragastis, PMI president. "PMI will develop a family of PXI Express-compatible 26.5GHz RF/microwave down-converter modules to meet the performance requirements of both military and commercial applications."

Synthetic instrumentation, a subset of virtual instrumentation, combines modular hardware such as up-converters, down-converters, digitizers and high-speed I/O with a software platform to create user-defined test and measurement systems. The synthetic instrument these three companies are developing, for example, makes it possible for engineers to stream high-bandwidth RF and microwave data across the high-speed PXI Express bus directly to a processor for application-specific analysis. Using a software-based approach with general-purpose hardware, synthetic instrumentation provides engineers and scientists with the flexibility to emulate multiple traditional instruments and add new functionality over time to support future needs and technologies.

"By working with National Instruments and PMI to build a synthetic instrument, we are giving engineers a faster and more cost-effective test and measurement solution," said Robert Wade Lowdermilk, BAE engineering fellow. "PXI Express is a critical part of this new solution because it provides the increased bandwidth needed for RF and microwave applications."

The new PXI Express-compatible RF and microwave down-converter family complements the wide breadth of PXI modules NI has developed for RF and communications applications, including high-performance IF generators and digitizers that take advantage of the high bandwidth of the PXI backplane.

"PXI Express delivers the highest bandwidth and lowest latency of all mainstream commercial test and measurement bus technologies," said Eric Starkloff, NI director of test product marketing. "The power of PXI Express makes it possible for engineers and scientists to create robust, software-defined instruments. We are excited to work with BAE Systems and PMI to increase the capability of PXI in both military and commercial RF applications."
