PRODUCTS EDITOR'S CHOICE LOW-FREQUENCY NOISE ANALYSER
Keysight Technologies has reached a new milestone in low-frequency noise measurements through its work with leading research centres in Europe, Middle East, Africa and India (EMEAI). Using the new Advanced Low-Frequency Noise Analyzer (A-LFNA) and WaferPro Express software, designers can now measure noise more accurately in an even broader range of electronic devices. Noise is one of the main limiting factors in electronic devices, including sensitive parts such as sensors and memories. As a result, the ability to monitor noise using a statistical approach on a large number of samples and different devices is more critical than ever before. “Since introducing the advanced low-frequency noise analyser,
Keysight has actively engaged with research centres that are world- renowned in the field of noise measurements,” said Cédric Pujol, EMEAI device modeling business development manager for Keysight EEsof EDA. “These collaborations have driven our developments into a broad range of applications, allowing the analyser to increase its versatility in
flicker-noise and random telegraph noise measurements. They also helped strengthen the use of the analyser for devices used in industrial electronics and in 5G and IoT-based devices.” The cornerstone of Keysight's collaboration with research centres, such as Sweden’s Chalmers University, Germany’s Fraunhofer EMFT, Belgium’s IMEC, and France’s LAAS-CNRS, is the addition of WaferPro Express software, a measurement framework that benefits from Keysight’s years of experience in device modeling. The Keysight A-LFNA now provides designers the flexibility to transform their low-frequency noise measurements into mathematical models. Other achievements resulting from the ongoing collaboration include an extension of the A-LFNA to enable noise measurements on CMOS sensors down to ultra-low frequencies (0.030Hz) and on power devices with a 200-V bias voltage. In support of bulk silicon and silicon on insulator (SOI) technologies, the A-LFNA also now asserts a state of the art noise floor (2E-27 A2/Hz). Additionally, it has been upgraded to measure noise power densities up to 40MHz.

Pesticides in fruit and vegetables, hormones and antibiotics in meat, mycotoxins in foodstuffs and animal feed, or bacteria and germs in drinking water – polluted or otherwise contaminated food and drink pose a significant health risk. Until now, time-consuming and expensive laboratory tests were necessary in many cases to detect pollutants and contaminants in foodstuffs and liquids. Now a biosensor system developed by the Swedish company CapSenze, which integrates an optimised evaluation circuit from Fraunhofer IIS, is able to analyse liquids by means of biochemical sensors in a couple of minutes. The system is suited for mobile use due to its convenient size which is comparable to a box of matches. The biosensor system can, for example, be used
for on-site detection of contaminants in water and all water-soluble substances. It can also be employed for mobile foodstuff inspection, to monitor food chains and for detecting doping agents. Supplying measurement data in the pico- to
femtomole range, the six different sensors of the biosensor system allow simultaneous detection of six
different substances. Different sensor coatings, depending on the substance to be detected, are used to determine the presence of unwanted substances in foodstuffs and animal feed. The biosensor system is a highly sensitive piece of equipment which can identify, with the corresponding sensor coating, the presence of biochemical substances such as hormones, pesticides and mycotoxins in extremely low concentrations. The biosensor system
employs molecularly imprinted polymers (MIPs). The gold-plated electrodes of the device are coated with these selective MIPs. In the same way that a footprint makes an impression in wet cement, the molecules of
the specific target substance are imprinted in these polymers. When the molecules of the pollutant or contaminant come into contact with the corresponding molecularly imprinted polymer, they then form a bond and change the electrical properties of the electrode. Each sensor is designed to react solely to a specific target substance and can even detect it in extremely low concentrations.

binder UK’s latest addition to its M12 offering are S and T coded insert moulded cable connectors designed for power applications up to a rated current of 12A. The 814, 813 series are suited for voltages up to 63VDC (T-coded) and 630VAC (S-coded) and are supplied with either three +PE or four gold plated contacts. According to binder UK, a key feature is connection security since coding eliminates mismatching.

S AND T CODED INSERT MOULDED CABLE CONNECTORS These new M12 connectors
will find wide applications across many industrial sectors in automation and control systems. As a result, they are rated to IP67 and binder UK is supplying them with environmentally-resistant black PUR cable in standard lengths of 2m or 5m. Both male and female connector versions are available
NEW OPTICAL SENSOR HEAD
The AQ2200-232 is a new high- performance optical sensor head which joins Yokogawa’s existing family of optical power meter modules in its modular optical test platform. The AQ2200-232 sensor head is
used in conjunction with the dual- port AQ2200-202 interface module, and is targeted at making accurate measurements in challenging applications such as power testing of laser chips in free space light, I/L curve measurement of laser-diode modules and multicore fibre measurements (with an MPO connector adapter). Key features are a 5mm diameter
as well connecting cables – all in both S and T coding.

cooled detector, ideal for measurements in free space, a wavelength measurement range from 800 to 1700nm, and a power measurement range of +15 to -90dBm. It also offers best-in-class uncertainty of ±1.8 per cent, high stability with constant- temperature control, and a wide single- range power range of 30dB. “With the launch of the new optical sensor head, Yokogawa is expanding its multi-application modular optical test platform in line with market demands for higher-speed automatic testing of optical devices in free space, which helps to reduce testing time - and hence costs - compared to fibre- coupled tests,” says Terry Marrinan, Yokogawa Europe & South-East Asia.
