Tektronix Develops First Methods of Implementation for UWB WiMedia 1.2

Tektronix, Inc., a leading worldwide provider of test, measurement and monitoring instrumentation, announced it had created the world’s first Methods of Implementation (MOI) for the new Ultra-Wideband (UWB) WiMedia PHY Test Specification Version 1.2 and released a new version of UWB Analysis software for DSA/DPO70000 series oscilloscopes that provides additional measurements for UWB WiMedia 1.2. With the new WiMedia PHY Test Specification Version 1.2 adding more receiver testing, the Tektronix AWG7102 Arbitrary Waveform Generator and RFXpress signal creation software are the best choices for engineers working with v1.0 and v1.2 and planning for v1.5.

“Customers working with UWB WiMedia need simplified test methodologies and the ability to trigger, capture, and analyze high speed RF signals,” said Brian Reich, vice president, Performance Scopes Product Line, Tektronix. “With the new MOI providing step-by-step instructions to perform 1.2 specification compliance testing and the latest UWB Analysis software, Tektronix provides customers the most capable toolset for debugging and analyzing complex UWB waveforms while running on the industry’s highest performance hardware. No other combination of software and hardware in the market is able to match Tektronix for UWB WiMedia analysis and performance.”

Transmitter Analysis
For UWB WiMedia radios using MB-OFDM technology for Certified Wireless USB, next generation Bluetooth, WiNet and Wireless FireWire (IEEE1394) applications, Tektronix UWB Analysis software reads the digital information from the RF waveform to determine the demodulation method on a packet-by-packet basis. By reading the digital information from the RF waveforms, UWB Analysis 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 the features of the world’s highest performing 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.

Receiver Testing
The Tektronix MOI covers the new v1.2 requirements for receiver testing. RFXpress software running on the AWG7102 provides an efficient way of creating compliant and non-compliant WiMedia waveforms for all bandgroups, data rates and both hopping – Time Frequency Interleaving (TFI) and Time Frequency Interleaving over 2 Bands (TFI2) – and non hopping – Fixed Frequency Interleaving (FFI) – Time Frequency Codes. This enables WiMedia designers and validation engineers to improve the reliability of their designs. With 20GS/s sampling technology engineers can create signals in bandgroups 1 and 2 that are generated directly from the AWG7102 without the need for an external I/Q modulator. For the higher frequency bandgroups the AWG7102 provides added flexibility by enabling waveform creation through either I/Q modulation or less expensive mixing tools. The AWG7102 arbitrary waveform generator provides comprehensive WiMedia signal generation support for MAC and PHY layers.

In addition, RFXpress has the ability to add impairments like time synchronized Gaussian noise at the WiMedia Packet level (Pre-amble, PPDU Header and PSDU), create tone nulling and introduce realistic interference to WiMedia waveforms from sources including WiFi (802.11a and MIMO), WiMAX and Radar.

Leading Test Bench for UWB WiMedia
Tektronix offers a leading Digital RF test bench for WiMedia and other UWB applications with an industry best combination of hardware and software. The new WiMedia MOI offers a step-by-step test methodology for the new Ultra-Wideband (UWB) WiMedia PHY Test Specification Version 1.2 release. For transmitter testing, UWB Analysis software combined with the DSA72004 oscilloscope offers the widest bandwidth, fastest rise time and lowest noise density that enables users to capture and analyze UWB signals with higher accuracy than competitive instruments. Additionally, the AWG7102 arbitrary waveform generator is the only instrument on the market today that can recreate both non-hopping (FFI) and hopping (TFI and TFI2) signals for WiMedia applications and develop and prepare for future device requirements for Detect and Avoid (DAA) technologies. RFXpress software on the AWG7102 enables engineers to create UWB signals quickly and easily to improve the reliability of their designs.
