Media processing blade Multi-touch A


new AdvancedTCA (ATCA) media processing


blade for telecoms applications has the highest density of digital signal processing (DSP) cores of any


commercially available blade.


The blade is the fi rst result of a collaboration between Emerson Network Power and Octasic, a Canadian developer of media and baseband


processing solutions. With up to 576 DSP cores and running sophisticated media processing software, the ATCA-8320 will enable communications equipment companies to


Digital radio test system


A


erofl ex’s new 3550 Digital Radio Test System features


a colour touch-screen and enhanced specifi cations. This lightweight instrument


(3·8 kg including battery) is suitable for fi eld-testing analogue, DMR, P25, NXDN and dPMR systems. It allows the user to test all aspects of a radio system – transmitter, receiver, cables, and antennas – with features typically found only in benchtop equipment. It also meets MIL-PRF-28800A specifi cations for humidity, shock, and vibration, with an operating range of 0º C to +50º C. On its internal battery, it can operate continuously for up to 4½ hours.


The 3550 allows the user to test all aspects of the radio system – the transmitter, receiver, cables and antenna


gateways and servers, media resource functions, mobile video optimization, video


communications and conferencing servers, and interactive


voice and video response systems. The new product is expected


simplify and accelerate the


development and deployment of very high density IP media processing applications. These applications include session border controllers, media


to achieve large space savings by replacing many traditional server or other media


processing blades when adding voice or video functionality to a communications system.

Faster localization of radio interference N


Embedded multi-touch display platform from andersDX

n iPad-like user experience in non-consumer electronic


devices is promised by the latest addition to the andersDX family of embedded display platforms. The andersDX DX4 is


arda Safety Test Solutions has equipped its Interference and Direction Analyzer IDA-3106 with additional functions that allow even faster


and more reliable localization of interference and unknown signal sources. It is now possible to localize pulsed or sporadic signals using a horizontal scan for direction fi nding. The spectrogram display shows the variation of the spectrum with time. Deviations from a reference trace can be seen at a glance using the delta spectrum display. The IDA-3106 now offers a Max Hold algorithm for localizing unknown


sources with a horizontal scan. This allows the instrument to produce a polar diagram from pulsed and cyclic or sporadic signals and to determine the direction of signals that have hitherto been diffi cult to localize, such as radar installations or intermittently used walkie-talkies. The IDA-3106 records up to 400 compressed individual spectra for the


spectrogram display and shows the signal strength in colour. This visualizes the variations in the spectrum with time, which can give information about the type of signal, so that industrial control equipment with cyclical signals, mobile communications services using frequency hopping, stationary transmitters, and sporadic emitters can all be distinguished from each other. A new feature is the ability to


save spectra as reference traces and display the current spectrum as a difference or delta spectrum. In this way, deviations from the normal status, such as new sources in the communications band or an unusual state in an industrial plant, can be seen immediately.

described as the fastest, easiest and most cost-effective way for non-consumer device manufacturers to implement a next-generation PCAP multi-touch display interface, optimized for and pre-integrated with a powerful embedded Linux computer. The DX4 offers long-term availability, outstanding technical support levels and functional upgrades, and a unique device form-factor independent design. Paul Mullen, sales director of


andersDX, said: “By delivering a completely pre-integrated solution, with a multi-touch PCAP interface ready to drop into an any design, DX4 speeds time to market, lowers development costs, and raises overall user experience for end-users that demand iPad-like usability.” At the heart of the DX4 is a


powerful, fanless single-board computer, based on the TI DM3730 processor and running Linux. With two CPU cores in a single package and a DSP processor for video processing, it can handle even the most graphic-intensive applications. Designers can take advantage of multiple interfaces and communication ports, including UART, SPI, I²C, USB, ethernet, SDcard, Wi-Fi and Bluetooth.
