Tektronix Inc.'s methods of implementation (MOI) document for the new Ultra-Wideband (UWB) WiMedia PHY Test Specification Version 1.2 reflects the additional receiver testing required in the spec.
In addition to the cookbook, the company also released a new version of UWB Analysis software for DSA/DPO70000 series oscilloscopes to accommodate additional measurements specified for UWB WiMedia 1.2.
For UWB WiMedia radios using MB-OFDM technology for Certified Wireless USB, next generation Bluetooth, WiNet and Wireless FireWire (IEEE1394) applications, the UWB Analysis software reads the digital information from the RF waveform to determine the demodulation method on a packet-by-packet basis.
The software automatically determines which demodulation method is used, data rates, time frequency coding, the pass/fail test limits, and constellation type that is then displayed. Detection and analysis is done on each packet from the RF content, greatly simplifying setup and speeding analysis and compliance tests.
UWB Analysis is augmented by a real-time oscilloscope and provides the specific modulation and spectral analysis for WiMedia Version 1.2. This is especially useful for engineers designing, testing and integrating UWB radios into Certified Wireless USB, next generation Bluetooth, and other industry consumer and computer applications.
