USB data acquisition at 750kHz/channel across 6 analog inputs With the DT9816 series Data Translation offers a range of lowcost USB data acquisition modules for simultaneous sampling of up to six analog signals. Unlike comparable measurement instruments in the same price range, these modules feature separate 16-bit A/D converters per input channel instead of multiplexed inputs. This eliminates phase shifts and allows simultaneous, synchronous measurements on multiple inputs. The series provides different models, from the proven DT9816-S with a sampling rate of up to 750 kHz per channel, to the DT9816 with 6 x 50 kHz and the DT9816-A with 6 x 150 kHz. The compact modules run entirely on USB power so that no external power supply is needed. This makes them suitable for portable measurement and test applications. Screw terminals on the module allow easy signal connections. In addition to the six analog inputs, all models of the series also provide 16 digital inputs and outputs. A counter/timer supports frequency measurements, rate generation and other operations. The modules ship with the QuickDAQ measurement software, offering a complete ready-to-measure data acquisition solution. The supplied software package comprises 32/64 bit drivers for the standard Windows operating systems as well as a comprehensive range of software tools, such as interfaces for LabVIEW, MATLAB and .NET. Data Translation www.datatranslation.eu Debugging tool supports safety-oriented Linux version The Trace32 debugging tool from vendor Lauterbach GmbH is now available for ElinOS, an embedded Linux product from Sysgo. ElinOS runs under Sysgo’s safety and security optimized operating System PikeOS as a ‘personality’. PikeOS developers were already able to use Trace32. The PikeOS awareness provides access to PikeOS resources such as partitions, processes and threads. Because PikeOS is also a virtualization platform, it is important to be able to debug any application, whatever partition or type of partition (called personality in the PikeOS terminology) this application belongs to. The new version of Lauterbach’s Kernel awareness now provides now the possibility to debug any thread of ELinOS, used as PikeOS Linux personality, and in SMP mode if needed. The first implementation has been achieved on Freescale’s i.MX6 series platform. Further platforms will be available soon, affirms Lauterbach. Performance analysis on PikeOS tasks and Linux processes can be performed, showing when and which task was running, how much time each task consumed and how often it was pre-empted. To comply with the full MMU support of PikeOS, Trace32 also includes full MMU support, so the user is able to debug several tasks in different PikeOS partitions concurrently. Lauterbach GmbH www.lauterbach.com From 70 kHz to 145 GHz in a single sweep With its new VectorStar ME7838D broadband network analyzer, RF test expert Anritsu offers industry-best frequency coverage of 70 kHz to 145 GHz in a single sweep using a coaxial test port. Applications are on-wafer device characterization for 77 GHz automotive radar devices, E-band wireless communication, and emerging applications above 110 GHz. The VectorStar ME7838D conducts a single sweep on a device over multiple RF, microwave, and millimeter wave (mm-wave) waveguide bands, allowing engineers to more accurately characterize integrated circuits and other RF building blocks. Due to the instrument’s ability to perform sweeps from rather low frequencies in the kHz range to 145 GHz, engineers can create more accurate models and subsequently have fewer design turns when devices are subsequently used in applications. The key enabler for broadband operation to 145 GHz is the MA25300A Non-Linear Transmission Line (NLTL) module. The module, also new in Anritsu’s catalogue, extends the frequency range of previous NLTL modules and is compatible with the basic VectorStar ME7838 system. Thus, all versions of the ME7838 series can be upgraded to ME7838D 145 GHz performance. At the opportunity of the ME7838D roll-out, Anritsu also introduced a novel 0.8 mm test port connector for use with the VectorStar ME7838D broadband system. The connector creates new opportunities for advanced network analysis and system design above 110 GHz. Anritsu www.anritsu.com Texas Instruments bets on iBeacons with reference designs Texas Instruments has announced its support for iBeacon technology across its Bluetooth low energy portfolio including the company’s Bluetooth Smart SoCs, SimpleLink CC2541 and CC2543 wireless microcontrollers (MCUs), its Bluetooth dual mode SimpleLink CC2564 solution, and the BL6450Q automotive connectivity device. TI is also launching a new location app, with iBeacon technology for its CC2541- based SimpleLink SensorTag development kit, as well as a new low cost, small form-factor broadcaster reference design based on the CC2543. The CC2543 is a low-cost version of CC2541 optimized for beacons and broadcast applications. The app allows engineers to upload a floor plan and “place” SensorTags to easily set up an indoor positioning system. The app provides feedback on how near users are the SensorTags and can launch a user-specified URL when they are in the immediate vicinity of a SensorTag. Additionally, existing SensorTags can be updated with the latest SensorTag App through an over-the-air upgrade to be compatible with iBeacon technology. TI is also introducing a coin cell-sized, low cost and low-power broadcaster reference design that enables fast volume production of devices with iBeacon technology based on the SimpleLink CC2543. The Sensor- Tag reference design is FCC-certified and includes Gerbers, schematics, layout, and BOM.
