IFR LAUNCHES UNIQUE NEW RF DIGITIZER FOR BETTER AND MORE FLEXIBLE RF SIGNAL PROCESSING

2319E RF test system copes with rapidly changing wireless standards

 

CTIA, Las Vegas, Nev.  Mar. 20, 2001 - IFR Systems (Nasdaq:IFRS) today announced the launch of the 2319E, the first in a series of new signal analysis instruments from IFR. The 2319E is a RF digitizer for 2G, 2.5G and 3G digital cellular testing. IFR's newest instrument for wireless test offers manufacturers the best choice for conversion of broadband radio frequency (RF) signals into high quality, digitized data for external processing in a personal computer. When combined with an optional high power digital signal processing (DSP) card and IFR software, the 2319E can be used as a substitute base station receiver during early research and development phases of new mobile phones.

About the 2319E RF Digitizer

The 2319E is a benchtop or rack-mounted instrument for use in RF communications research and development. In later product releases, the 2319E will add production test capabilities.

Designed with 3G mobile systems in mind, the 2319E operates across a wide frequency range and provides a generous 20 MHz digitization bandwidth sufficient to capture four UMTS radio channels. The instrument provides high-quality conversion of complex modulated RF signals into digitized data. The output data is then made available through a variety of interfaces for external processing in a PC using application software developed by IFR, the customer or by a third-party developer.

The choice of output interface is determined by the bandwidth requirements of the application, selected from low, medium or high-speed options. Data may be transferred in real-time directly from the digitizer or captured into internal memory and output in bursts at a slower rate. In either case, data can be represented as a digital IF (intermediate frequency), or digital IQ (in phase & quadrature phase). Together this caters cost-effectively for the widest range of test system needs.

IFR provides more of what engineers really need inside the instrument

Today's test instruments for signal analysis are made up of a combination of signal capture, signal processing and results presentation. To meet the measurement challenge of wireless designers and provide flexibility to deal with rapidly changing standards, IFR redefined these boundaries by completely separating signal capture from signal processing and results presentation. In doing so, the barriers to application development are unlocked and open to all. Engineers enjoy a much better return on investment because the processing power of their PC can be upgraded to remain state of the art. By offloading the signal analysis and processing to a PC, engineers have the flexibility to add to their own software-based test cases, which can build up over time into a comprehensive library of custom test cases. The 2319E RF digitizer also gives engineers greater confidence in their measurements because of IFR's uncompromising standards for low noise, high dynamic range, and accuracy.

"The 2319E is a unique instrument that makes a great platform, especially for advanced system emulation applications," said Tim Carey, manager, signal analyzer product line, IFR Systems. "What drove us to create it was knowing that standards are moving faster than the hardware. We came up with the concept of "divide and conquer" by separating signal capture from analysis. Engineers benefit from never having their hardware go out of date due to shifting wireless standards. In effect, we've given them more of what they need and less of what they don't need in the instrument."

2319E applications will start with radio emulation and verification The range of RF applications for the 2319E are determined entirely by the external software. The primary application at launch is real-time demodulation for radio emulation and verification. For example, the 2319E can substitute for a base station receiver during early R&D phases of new cellular systems. Real-time continuous demodulation of radio signals,including third-generation WCDMA and GSM/EDGE can be performed on external DSP modules running IFR software. Raw symbol data is extracted from the digitized sample data and output to the user for further layer 1 processing. Easy customization of this software has been a design consideration from the outset to simplify integration into existing test systems.

Other application-specific software programs will be developed by IFR to meet the most pressing needs of the wireless manufacturers.
