PC-based scopes use USB 3.0, add 512 Msample memory depth option PicoScope 3000D Series oscilloscopes have up to 200 MHz bandwidth, two or four analogue channels plus 16 digital channels on the mixed-signal (MSO) models, and deep memories from 64 to 512 mega-samples. The scopes offer a maximum real-time sampling rate of 1 Gsample/sec and feature a USB 3.0 interface; they also host a built-in arbitrary waveform generator (AWG). Deep memory enables long timebases with the fastest sampling rates; for example, at 1 Gsample/ sec sampling rate you can capture a 500 msec waveform— that’s half a billion samples, Pico points out—while hardware acceleration keeps the display updating smoothly. The 512 Msample buffer memory can be segmented, enabling acquisition of up to 10 000 individual waveform segments of 50 000 samples, with less than 1 μsec re-arm time between each segment. Memory segmentation is beneficial when analysing waveform bursts or serial data packets that include long gaps. The PicoScope can be set to trigger on each packet and skip the gaps that are of no interest. This function allows users to acquire, for instance, CAN data packets over several minutes and then analyse the packet content at a later point in time. The oscilloscopes are multifunction include a spectrum analyser and arbitrary waveform generator (AWG), and advanced functions as standard, such as serial bus decoding, mask limit testing, maths channels and filtering. Advanced triggers include pulse width, interval, window, window pulse width, level dropout, window dropout, runt pulse, variable hysteresis, and logic. Pico Technology www.picotech.com Audio PA for in-car systems with ‘light’ hybrid electrics The 4-channel power amp IC, TCB001HQ, has been designed to offer enhanced noise tolerance and to limit the effect of interference generated by in-car mobile phone use. Stopped vehicles fitted with engine idling reduction technology can suffer significant drops in battery output voltage, which can adversely affect the sound quality and clarity of in-car entertainment systems. By reducing the minimum operating voltage from 8V to 6V, this power amplifier offers more stable operation, prevents loss of sound and reduces noise disturbance. With mobile phone interference protection, the TCB001HQ improves the in-car listening experience. The TCB001HQ also offers a newly developed filter circuit and reinforced protection circuits, including thermal overvoltage, output to VCC, output to GND and output to output protection, to ensure increased reliability. Built in mute and standby functions help to maintain battery charge. Toshiba Electronics Europe www.toshiba.semicon-storage.com Bluetooth, WiFi for in-car use combined in one module Addressing the rising demand for systems that integrate smartphones into the infotainment system in vehicles, Alps has developed a module that combines Bluetooth and WiFi functionality in one product, the UGZZF series. Increasing smartphone functionality has given rise to new services making use of cloud-based data, a trend creating spillover effects for the automotive electronics market. Car navigation, display audio and other automotive systems incorporate Bluetooth communication functionality for such features as handsfree calls and music playback using a smartphone or similar device. In recent years, however, wireless LAN is increasingly being added to enable high-speed communication with cloud networks via LTE-capable smartphones. Additionally, systems which use Bluetooth, as modules that also contain an antenna, must have Bluetooth SIG certification, as well as any certification specified by radio legislation in each country. This necessitates spending an enormous amount of time and effort on examination and testing. Furthermore, many car audio and other automotive systems have CPUs with low processing capability, feeding demand for modules with integrated Bluetooth protocol stack and wireless LAN driver. The antenna-integrated UGZZF Series Bluetooth/Wireless LAN module is ALPS’ answer to this set of needs. By incorporating the Bluetooth protocol stack into the module, ALPS takes responsibility for obtaining for the module both Bluetooth certification and certification required by regional radio legislation. The module is also equipped with a wireless LAN driver, enabling Wi-Fi connections without burdening the host CPU. The module meets the requirements of a wide range of customers and also helps to reduce the antenna and system design and testing, software development and certification workload of equipment manufacturers. ALPS www.alps.com Mass flow sensors make gas boilers more efficient Energy efficiency is a pivotal issue for many users today. With a series of new mass flow sensors, Sensirion helps developers of gas-operated boilers to better control their energy consumption. Sensirion’s new calibrated and temperature- compensated sensors and sensor solutions ensure precise and reliable measurement of the air mass to a combustion chamber, enabling higher boiler efficiency and a higher increase in the modulation ration which in turn leads to higher boiler lifetime. Thanks to compact size and flexible modification options, the mass flow sensors can be installed in almost any boiler. In addition, the sensors guarantee a wide dynamic control range, the elimination of zero-point drift, high repeatability and accuracy as well as the option of certified intrinsic safety. The performance of these sensors is based on Sensirion’s proprietary CMOSens Technology, in which the sensor component and the evaluation circuit are integrated on a single CMOS microchip. In conjunction with a specially developed sensor packaging, the result is a more cost-effective system with significantly higher precision and repeatability, representing a quantum leap in mass flow and differential pressure measurement, promises Sensirion.
