HIGH BANDWIDTH OSCILLOSCOPES
According to Keysight Technologies, chipsets that take advantage of its leading edge Indium Phosphide (InP) semiconductor technology will enable it to deliver real-time and equivalent- time oscilloscopes in 2017 that offer bandwidths greater than 100GHz, with significantly better noise floors than what is currently available. The real-time oscilloscopes will also feature a new 10-bit analogue-to- digital converter (ADC) that allows higher vertical resolution of signals captured at ultra-high bandwidth, and more than one maximum bandwidth input channel per oscilloscope to enable tight channel synchronization. Engineers working with next-
generation, high-speed interfaces, such as the upcoming IEEE P802.3bs 400G, as well as terabit coherent optical modulation, will need oscilloscopes for electrical parametric measurements. These technologies and others will play a key role in validating fifth-generation wireless (5G) designs. These interfaces will also drive the need for high-performance, real-time and equivalent-time signal analysis capabilities to 100GHz and beyond. As data rates continue to extend beyond 56Gb/s NRZ and 56 GBaud multi-level signalling, engineers will need not only higher bandwidth, but also higher vertical resolution and lower noise floors to address their validation challenges, and the new chipsets have been designed with this in mind.

HIGH PERFORMANCE OPTICAL SPECTRUM ANALYSER LAUNCHED
To meet customer needs for a compact, high-performance OSA that is also easy to use and maintain, Yokogawa has launched the AQ6376 Optical Spectrum Analyser (OSA). According to the company, this sets a new ‘world standard’ for grating-based OSA capabilities in measuring signals with a wavelength beyond 3µm, designed to operate in the short-wavelength infrared (SWIR) as well as in the mid-wavelength infrared (MWIR) regions. Covering wavelengths from 1500 to 3400nm, this uses an
advanced monochromator design that helps to separate spectral signals in close proximity to one another, and improves the dynamic range by reducing the influence of stray light. The instrument offers high measurement speeds of up to
0.5sec/100nm, simple set-up and easy operational features – including a data-logging function for recording analysis results such as multi-peak measurements at up to 10,000 points per channel, with time stamps which can be displayed in table and graphical formats, storage of the optical spectrum of each measurement for reviewing and troubleshooting, and a Windows file sharing function in addition to Ethernet/GPIB and USB interfaces for transfer of data. The AQ6376 is designed for measurement in many
different application areas of photonic technology such as environmental monitoring for air pollution analysis, Infra-Red (IR) spectroscopy, scientific and medical diagnostics, and the nonlinear super continuum light generation. It will therefore enable manufacturers of light sources or passive optical components to save development time and further improve the measurement precision of their devices.

MEASUREMENT True colour measurement is required in many sectors, enabling companies to select, monitor, grade and sort various types of coloured objects involved in a range of applications. To help, Micro-Epsilon has introduced the colorCONTROL ACS7000, which is designed to measure the actual colour of the target by identifying their coordinates in the colour space. This identifies colours using any
of the XYZ; L*a*b*; L*u*v*; RGB and DIN99 measurement definitions and can continually monitor a production process and output the colour measurement via Ethernet, EtherCAT or RS422. It can also be taught pass fail/limits and then output out-of- tolerance alarms using digital I/O. As a result, it can be used for
applications where colours and shades must be examined on-the-fly and to very high accuracies – including automotive paint inspection, colour measurement of car interiors, coloured glass, transparent film and sheet production, printing, packaging, medical technology, food, cosmetics, pharmaceuticals and many more.

MEETING NEW IMMUNITY TESTING REQUIREMENTS
The robust NSG 4060 testing system from Teseq meets the new requirements for immunity testing to low frequency disturbances in the frequency range of 15Hz to 150kHz. It complies with current testing standards including EN 61326-3-1, IEC 61850-3, IEC 60255-22-7, IEC 60533/IEC 60945, IEC 61000-4-16 and IEC 61000-4-19. Said to be ideal for use by manufacturers of smart
electrical meters, industrial circuit breakers, industrial Ethernet and shipboard equipment, this features a full range of verification accessories which allow in-house confidence checking of differential CDN (CDND). Disturbances are coupled onto cables in common mode (IEC/EN 61000-4-16) or differential mode (IEC/EN 61000-4-19) with continuous levels ranging from 1V to 30V. The system also features an extension unit that expands the test range frequency to DC and the amplitude to 300V for short term tests. The unit, which combines a signal generator
and integrated power amplifier, features a user port for four TTL inputs and four TTL outputs, as well as supply voltages for individual monitoring and control applications. There are also ports for generator output, system and coupling network control, as well as phase synchronization input.

for colour measurement/evaluation, its performance is typically a ΔE of 0.1, enabling users to solve applications that were previously not possible. Traditionally, high performance colour measurement systems are only able to measure at slow speeds, however with the ACS7000 having a measurement speed of up to 2kHz, it is possible to integrate the system into the production processes, improving automation, quality control, production efficiencies and product quality, whilst also reducing operational costs and waste. The colorCONTROL ACS7000
series has a choice of three different sensor families: the ACS1, circular sensor (ACS2) and a transmission sensor (ACS3). Designed for different measurement tasks, each family has specific optical angles, spot geometries and focal distances.
