Optical Device Tester

Anritsu Company (Richardson, TX) has introduced the BERTWave MP2110A, an all-in-one instrument that conducts simultaneous BER measurements and eye pattern analysis to more efficiently evaluate multi-channel optical devices used in optical communications systems, including 100GbE, InfiniBand EDR, and 32G Fibre Channel. The BERTWave MP2110A features a built-in BERT that can be configured with up to 4 channels at up to 28.2 Gbit/s, and up to a 2-channel sampling oscilloscope. This single-instrument design allows the BERTWave MP2110A to conduct simultaneous TRx BER measurements of multi-channel optical modules used by 100GbE standards, such as QSFP28, and other standards, such as InfiniBand EDR and 32G Fibre Channel, as well as simultaneous 2-channel eye pattern analyses.Click here to learn more

Reliability Testing of High-Power Devices

Before a new high-power semiconductor device can be used for industrial applications, it must be thoroughly tested to determine if it will survive environmental stresses and continue to meet specifications. This is especially true for the latest wide-bandgap semiconductor materials such as silicon carbide (SiC) and gallium nitride (GaN) to ensure they can withstand high voltage and temperatures.

Electronic Device Monitors the Heart and Recognizes Speech

Researchers from the University of Colorado Boulder and Northwestern University have developed a tiny, soft, and wearable acoustic sensor that measures vibrations in the human body, allowing them to monitor human heart health and recognize spoken words. The stretchable device captures physiological sound signals from the body, has physical properties matched with human skin, and can be mounted on nearly any surface of the body. The sensor resembles a small Band-Aid®, weighs less than one-hundredth of an ounce, and can gather continuous physiological data.

Split Laser System for Environmental Monitoring

Environmental monitoring — the assessment of air, water, and soil quality — is highly important to oil and gas exploration companies, landowners, regulatory agencies, municipalities, and any organization measuring emissions and pollutants. The majority of monitoring technologies, however, are expensive and labor intensive, often requiring sample collection and preparation (i.e., external lab analysis) that can dramatically alter the sample and its inherent components. Of those technologies that do allow for in-situ analysis, few are amenable to measurements under harsh conditions, such as high temperature and/or pressure.

Measuring Tiny Forces with Light

Photons have no mass, but they have momentum. This allows researchers to use light to push matter around. Scientists at the Physical Measurement Laboratory (PML) at the National Institute of Standards and Technology (NIST) have taken advantage of this property to develop devices that can create and measure minute forces, an area traditionally underserved by the metrology community.

Laser Scanning Technique for Testing Fire-Damaged Concrete

Research at The University of Nottingham (UK) and the University at Ningbo (China) has found that laser scanning is a viable structural safety technique to detect the damaging effects of fire on concrete. Concrete is the most extensively used construction material worldwide with an average global yearly consumption of 1 cubic meter per person. Fire is one of the most serious potential risks to concrete structures such as bridges, tunnels, and buildings.

3D Measurement and Visualization of Displacement and Strain Fields

The Naval Research Laboratory (NRL) has developed a metrology workbench for the measurement and visualization of displacement and strain fields in three dimensions. The workbench uses two or more cameras to image a specimen, and includes custom software that implements the 3D Meshless Random Grid method.
