The included Test Flow capabilities let users quickly automate power-supply setups and measurements into test sequences.
More information about the E36300 Series triple-output programmable DC power supplies is available at www.keysight.com/find/e36300.
Laser Diode for (Rb) Rubidium Spectroscopy/Optically Pumped Atomic Clocks
The 795 nm DFB laser is the latest addition to eagleyard’s product portfolio. Next to the 780 nm DFB lasers and the gain chips for extended cavity setups (ECDL) the new laser enlarges the choice for Rubidium spectroscopy and the related application such as optically pumped atomic clocks.
The 14-pin butterfly package adds ready-to-use single-frequency-emission features by comprising thermoelectric cooler and thermistor enabling precise wavelength tuning. The package complying with industry standard is designed to provide electrical input as well as optical output in the same layer. It allows the convenient use of standard peripheral equipment such as mounts and drivers.
Major performance parameters are:
- wavelength: 795 nm (for Rb D1 line at 794.98 nm)
- line width: < 1 MHz
- mode-hop-free tuning range: >10 GHz
- output power: 80 mW
- 14-pin windowed butterfly package with integrated beam collimation
- optional integrated micro-isolator available
Single Frequency Laser Diodes have a wavelength-selective grating integrated in the laser chip. Thus, they operate on a single resonator mode emitting quasi-monochromatic radiation with a very small line width and low phase noise. The lasers can have very low-intensity noise because of the lack of mode partition noise. Due to the Gaussian mode, the output is diffraction-limited.
The choice of a DFB design instead of a similar DBR structure guarantees even a broader smooth tuning range around the operational point w/o the risk of experiencing spectral issues known as mode-hops, as these are given by design of a DBR diode, making the latter less suitable for the needs of atom spectroscopy.

MEMS Inertial Sensors Overcome Stiction Problems
Nanusens has announced that it has solved the problem of stiction in its MEMS inertial sensors. CMOS nano-sensor technology has been successfully used to solve the problem, which is a major source of failure for this type of sensor.
The problem of stiction in MEMS is caused by attractive forces that occur on microscopic levels such as Van der Waals and Casimir. These are surface area dependent and not mass dependent. In an inertial sensor design, there is a proof mass connected to a spring. This mass moves when there is an acceleration and the movement is detected by the mass acting as one electrode and the change in capacitance is measured relative to a second fixed electrode. However, if there is a large movement such as from a shock or collision, the mass goes beyond the normal range of travelling and touches a surface enclosing the sensor where it 'sticks' due to the attractive forces and stops working. This can be countered by having stronger springs, but this reduces the sensitivity of the sensor. A solution to increase the sensitivity could be to increase the mass, but this results in a greater surface area for the mass and so, unfortunately, more attractive forces.
The approach used by Nanusens is to reduce the sensor design by an order of magnitude from Micro Electro-Mechanical Systems (MEMS) with linear feature sizes of 1-2 µm to Nano Electro-Mechanical Systems (NEMS) where the features are 0.3 µm. This reduces the attractive forces significantly as the surface area reduction is in two dimensions, i.e., almost two orders of magnitude reduction. Reducing the proof mass could result in decreased sensitivity except this is offset by reducing the gap between it and the fixed electrode. The size reduction also means that the energy stored on the proof mass when it hits the surface in case of a shock is much less and the travelling gap is small. A shock with less energy is also easier to detach.
The new nano-sensors are made using standard CMOS processes and mask techniques. As only standard CMOS processes are used, and the sensors can be directly integrated with active circuitry as required, the sensors can potentially have high yields similar to CMOS devices.

PCB's new UHT-12™ miniature accelerometer was designed for applications that demand minimal sensitivity change across a wide temperature range. Model 320C53 features a sensitivity of 1 mV/g to complement the Model 320C52 sensitivity of 10 mV/g. Both models feature a UHT-12™ sensing element which provides a stable sensitivity over large thermal shifts.
Small and lightweight, these sensors weigh just 1.85 g with a size of 9.6 mm x 17.3 mm. They are hermetically sealed in a rugged titanium housing and feature easy to install thru-hole mounting. The accelerometers attach to test structures with an insulated mounting screw.
Both models have an operating temperature range of -100 to +325 °F (-73 to +163 °C). Model 320C52 has a frequency range from 1 to 10 kHz (+/- 5%) and Model 320C53 has a frequency range from 1 to 5,000 Hz (+/- 5%). A single pole low pass filter, with a corner frequency set to ≥20 kHz, is incorporated into each model which reduces the potential for saturation or clipping.
Built-in ICP® microelectronics provide a low noise, low impedance output signal capable of being transmitted over cable lengths of hundreds of feet. Any ICP® signal conditioner or data acquisition system that incorporates an ICP® constant current excitation can be used to power the accelerometers.

Software Analyzes Shocks
The new MSR ShockViewer data logger software, which specializes in analyzing shock events and jolts, allows you to clearly present extensive measured data, as well as quickly analyze and conclusively document critical events.
During transport, cargo is subjected to a multitude of external impacts that may cause it to sustain damage. Mini data loggers and the new MSR ShockViewer software, which is manufactured by the MSR Electronics GmbH Company in Seuzach, Switzerland, can be used to record, store and analyze the most important physical impacts on cargo (acceleration, temperature, relative humidity, air pressure, light) or other applications where shock data needs to be measured.
The most important physical parameters that should be monitored in a transport and logistics chain are accelerations, shock events, jolts and vibrations, as they may have a very negative impact on the mechanical structure of any industrial object or commodity. This is done in all three geometric axes (x, y, z) to obtain acceleration values in all directions. The 3-axis acceleration sensor starts recording data either when an acceleration threshold is exceeded or at a set time.
The logger data can then be analyzed very accurately using the new, intuitive MSR ShockViewer software. All measured values are given an exact “timestamp,” which can subsequently be used to reconstruct the time of an event accurately to the second.

Solid State Amplifier and Antenna Combinations Generate Up to 50 Volts per Meter
AR RF/Microwave Instrumentation has introduced a line of state-of–the-art solid state field generating systems for numerous applications. These products now offer an attractive alternative to using Traveling Wave Tube Amplifiers (TWTAs) driving separate antennas to generate field strength up to 50 V/m. Performance characteristics of this magnitude (both in frequency and output power) were previously dominated by low MTBF, short warranty TWTAs; however, these new solid-state designs offer better performance, increased reliability, and a 3-year warranty.
The amplifier and horn antenna combination form one completely housed unit which may be tripod mounted. These new “AA” series systems produce field strengths up to 50 V/m in two band-specific models over the 18 to 40 GHz frequency range when driven with a suitable signal generator. A separate rack mounted unit (AA1000) contains the power supply and control circuitry (RF and DC cables included) for interfacing with these products. The rack mounted assembly can be used for any of the AA series designs. AR can supply the AA model(s) and AA1000, in addition to a signal generator for a complete turnkey system. Standard products cover 18 to 26.5 GHz and 26.5 to 40 GHz frequency ranges.

Digital Platform Connects Machinery
thyssenkrupp connects machinery via a new digital platform. Thanks to “toii” all machines can communicate with each other. Due to predictive maintenance, the platform is also supposed to forecast the necessity of machine services in the future. The name chosen by the business area is a double play on words-- it spells IIoT backwards, the abbreviation for “Industrial Internet of Things”-- and it is pronounced like the word “toy,” an indication of how the new platform makes linking heterogeneous machines to existing IT structures “child’s play.”
The machines perform a wide range of tasks, were made by various manufacturers and differ in age. Now toii makes it possible to connect bandsaws and bending machines, mobile objects like cranes and forklifts and even complex production facilities such as slitting and cut to length lines and sophisticated processing solutions through milling machines and laser systems digitally in line with the Industrial Internet of Things. The digital platform allows the machines to share data and communicate with one another and with the IT systems. Processes can be planned and coordinated optimally and flexibly– across locations, worldwide.
An international Materials Services team of IT professionals from Germany, India and the USA worked together to develop toii. Alongside various projects in Germany, there are already plans to deploy the system in the UK and the USA.
