SR5500 WIRELESS CHANNEL EMULATOR VDT-Conversion Tool RF engineers want the realism of physical drive testing, but without the inherent impact to budgets and schedules. They also need to be confident that the RF conditions they’re using today are the same as those they’ll run tomorrow. For years RF engineers have dreamed of a way to take real-world APPLiCAtiOns RF data from drive testing, store it, and use it to re-create the • Research and Development same, repeatable RF scenario on the lab bench. Spirent’s Virtual Drive Test (VDT) for the SR5500 Wireless Channel Emulator • Design Verification brought that capability to the market for those who had the resources to convert captured drive-test data,. • Regression Testing Now Spirent introduces a tool to automate the conversion process • UE Benchmarking and comparison without requiring any software effort on your part. Now it’s faster and easier than ever to take advantage of Spirent’s Virtual Drive • Device Design Test capabilities. The powerful VDT-Conversion Tool takes RF data collected during drive testing and automatically converts it within minutes for storage and playback in the lab. Benefits • Reduced development costs – Minimize the need for expensive drive testing. • Reduced time-to-market – Fewer physical drive tests eases the strain of tight deployment schedules. Start “drive testing” whenever you see the need… within minutes. • Enhanced product quality – An absolutely repeatable drive test on a bench top. Quickly home in on RF issues that might otherwise go unnoticed until after deployment. sr5500 WireLess ChAnneL emuLAtOr VDT-Conversion Tool mapping data KeY feAtures • • WCDMA (Primary Synchronization Code [PSC] vs Time / Supports all bands for GSM, WCDMA & CDMA/EV-DO Channel) • Converts 4+ hours’ worth of drive test data within a few • CDMA (Synchronization Code [SC] vs Time / Channel) minutes • • GSM (Absolute Radio Frequency Channel Number [ARFCN] vs All data can be graphically displayed to allow easy analysis Time / Channel) mOre On the Vdt-COnVersiOn tOOL Velocity data The VDT – Conversion Tool helps resolve issues in days rather • Captured velocity than weeks. It supports up to 8 separate RF channels using lab-based base stations and SR5500 channel emulators. All OrderinG infOrmAtiOn combinations of RF technologies are supported (e.g. three GSM signals and five WCDMA). When the number of channels captured Part number description exceeds the resources available in the lab, mapping algorithms let you select the most significant information for your emulation. VDT-CT VDT - Conversion Tool VDT-CT-UMTS WCDMA & GSM Option Because scanning sample rates don’t always capture fast fading VDT-CT-CDMA CDMA Option effects, the tool includes algorithms for filtering out captured fast SR5500M-VDT-CT-PLAYBACK VDT - Playback License fading effects. The software then combines captured velocity data with statistically sound fast fading to create realistic RF effects.
