The newest version of WBT available via the update server (found by clicking the QRC logo on your WBT, and upgrading the firmware to the latest version – 2.1.x.x) has added IQ data access to the WBT API. With this extension, programmers can access all of the raw data in real time to perform value added functions such as signal detectors, conditional recording and playback rules, automation scripts, and analysis libraries.

In the next months, QRC and our partners will be creating many of these modules (called WBT Apps) on the Marketing Portal and Public Internet for WBT owners to use. Within the next quarter or two, a WBT App Store will be made available on the device itself to allow operators to browse/search for modules of interest and install them directly from their WBT.

In the meantime, many have been asking how they can make their WBT do x, y, or z easily. The 2.1 release includes a Programmer’s Development Kit that can be ordered from your QRC point of contact. This easy to use environment

allows a programmer to install the provided Virtual Machine Manager (Oracle VM Box), and launch a custom image that has all of the tools, documentation, and example code already installed and optimized for use on the WBT.

Presently available as a WBT App as an example is a Spectrogram add-on module. After installing this App, the

user is able to see a waterfall of the WBT’s spectrum in real time. This App (as all WBT Apps will be) was written exclusively using the WBT 2.1 API and is a demonstration of the possibilities in automation now available on the platform.

For a list of presently available Apps, please consult the marketing portal and/or public website. This newsletter will also provide highlights of especially noteworthy apps as they become available.

QRC has released the Signal Analysis Toolkit (SAT).   

The SAT includes two separate tools which together provide a comprehensive set of capabilities to analyze and process QVRT files on a Windows PC.    

Use of the SAT requires no programming and minimizes the time required to rapidly discover RF anomalies or to quantify spectrum behavior over time.   

Files created with the SAT can be played back through a WBT® for further analysis by other lab equipment, exported into Matlab® or directly used over the air. 

For more information, or to download free trials of the tools, go to the link:
