CRFS Debugs RFeye Spectrum Monitoring System with XJTAG Boundary Scan

CRFS (Cambridge Radio Frequency Services), a developer and manufacturer of innovative real-time spectral analysis tools, has selected the XJTAG boundary scan development system to debug, test and programme its RFeye[tm] real-time spectrum monitoring system. The XJTAG development system is being used by engineers at CRFS’s design facility in Cambridge, England, to speed up debug and test of ball grid array (BGA) populated printed circuits boards which form part of the RFeye system. XJTAG is also being used to create test harnesses to improve coverage during production testing at CRFS’s contract manufacturing partner’s site.

The CRFS RFeye system is a distributed, GPS-based interference measurement system that can survey radio spectrum. It can be tuned to a frequency between 10MHz and 6GHz and detect frequency data in real time. It has a fully programmable embedded Linux processing platform with high-speed digital signal processing acceleration support in the form of a Xilinx 1152-pin field programmable gate array (FPGA).

Alistair Massarella, CEO at CRFS, said: “XJTAG is an absolute necessity for any company that is designing complex circuits that feature high pin count BGA or chip scale devices. XJTAG is easy-to-use and incredibly fast which has enabled us to shave weeks off the development schedule for our RFeye module thereby leaving our development team free to develop rather than sitting around painstakingly debugging boards.”

CRFS has recently been selected by Ofcom, the UK communications regulator, to undertake one of the most detailed spectrum mapping projects ever conducted in the UK. It will use its purpose-built and technically-advanced RFeye system to gather the radio spectrum data. Applications for RFeye include frequency interference detection, spectrum usage database, license enforcement, spectrum release and liberalisation, cell planning, RF environment check and remote site monitoring.

“XJTAG’s appeal is also its versatility. It is designed to be used right throughout the product lifecycle from design and development through to the factory floor and beyond,” added Alistair Massarella. “XJTAG can also test both JTAG and non-JTAG devices which means that test coverage is very high – we can get to over 80% of devices on the RFeye boards via the JTAG chain. What’s more, XJTAG provides the ability to re-use and port test scripts between circuit boards which saves us loads of time.”
