A USB scope for Linux fans USB oscilloscopes are popular - only that the marketable supply is focused almost exclusively to Windows platforms. Pico Technology now redeems the growing flock of Linux users by offering such a software that runs under their preferred operating system. PicoScope 6 converts a Linux PC into an oscilloscope, FFT spectrum analyser and measuring device. On-device buffering, using deep memory on some devices, ensures that the display is updated frequently and smoothly enough even on long timebases. While only the most important features from PicoScope for Windows are included — scope, spectrum and persistence modes; interactive zoom; simple, delayed and advanced triggers; automatic measurements; and signal generator control - the company assures that more functuins will be added over time. Users can save captures for off-line analysis, share them with other PicoScope for Windows and PicoScope for Linux users, or export them in text, CSV and Mathworks MATLAB 4 formats. The oscilloscope software is available for Debian 7.0 (code named “wheezy”), Ubuntu 12.xx / 13.xx as well as other Debian-based distributions with mono-runtime version 2.10.81. or higher. Drivers are available for current scopes from the PicoScope 2000 to 6000 series. Again, the company said it is working to add driver support for older products. The PicoScope software requires an USB oscilloscope from the PicoScope range. Such oscilloscopes are available with bandwidths up to 1 GHz, up to 4 input channels, hardware vertical resolutions up to 16 bits, sampling rates up to 5 GS/s, buffer sizes up to 2 GS, and built-in signal generators. Other features available on some models include flexible hardware resolution, switchable bandwidth limiters, switchable high-impedance and 50 ohm inputs, and differential inputs. Pico Technology www.picotech.com Energy harvesting switch is KNX-RF readyx Cherry’s energy harvesting KNX-RF wireless switch module can directly be integrated into switches with customized control units or design-parts and requires no wires or batteries. It is designed for all switch series with a standard inner frame of 55x55mm. The actuation of the switching unit produces enough electrical energy to transmit a complete KNX-RF ready protocol in S-mode directly to any KNX-receiver. There is no need for a gateway and the configuration is done via ETS as standard. The transmitter has a range of 30m in the 868 MHz band. The radio electronics can also be used in the 915 MHz band. Geschäftsfeld Elektronische Systeme www.zf.com Global location chip targets wearables Adding a new level of activity and locationtracking to the growing fitness and wearable device market, Broadcom Corporation claims to offer the industry’s first Global Navigation Satellite System (GNSS) system-onchip (SoC), designed for lowpower, mass-market wearable devices such as fitness trackers and smart watches. Consuming 75 percent less power than existing GNSS devices, the BCM4771 GNSS SoC with on-chip sensor hub enables consumers to more accurately track and manage their health and wellbeing by delivering precision activity tracking and location data while consuming less power than traditional architectures. This enables location intelligence and the extended battery life needed by the growing wearable market. Wearable wireless device revenues are projected to exceed $6 billion in 2018 with sports, fitness and wellness as the largest segment with 50 percent share of all device shipments, according to ABI Research. The chip constantly monitors user activity levels and location history to improve accuracy while adding advanced features such as location batching. In addition, the BCM4771 significantly reduces power consumption and board area by combining its location capabilities with an integrated sensor hub, contextual awareness, and GNSS. The SoC is complimented by the company’s Wireless Internet Connectivity for Embedded Devices (WICED™) Smart and WICED Direct software development kits (SDKs) to provide additional wireless connectivity to the platform. Designed in 40 nm process technology, the BCM4771 GNSS SoC includes a sensor hub that integrates sensor inputs for its on-chip algorithms to detect the user’s context, accurately compute speed and distance traveled, and provide fitness applications with the GNSS track. Power savings and advanced accuracy are achieved by intelligently leveraging context detection through the tight coupling of sensor inputs and GNSS on a single SoC. The device also realizes a lower overall bill of materials (BOM) cost through the integration of a multipurpose sensor hub. Broadcom Corporation www.broadcom.com 1.8mm thin speaker delivers 80 dB Transducers USA’s piezo ceramic MLCT (Multilayer Ceramic Transmitter) series thin speaker features a unique simple acoustic multi-layer ceramic construction that produces a high output of 80 dB from only 16V. The device’s milliwatt power consumption and high conversion efficiency in a 30x20x1.5mm package makes it suitable for flat and narrow spaces. Waterproof design and anti-electromagnetic applications make it a product of choice for digital products, household appliances, voice repeaters, or music players. The MLCT series has a wide frequency range of 300Hz to 20kHz within a working temperature range of -20 to +70°C. Units will not cause electro-magnetic interference to any surrounding electronic device as well as eliminate any such interference on its own.
