Aerotech’s engineering reference guide serves as a valuable resource for all Aerotech motion and positioning control components and systems. Section 12 focuses on electrostatic discharge protection.
As Linear Technology’s Jim Williams explains, a large group of fibre-optic lasers are powered by DC current. Laser drive is supplied by a current source with modulation added further along the signal path. The current source, although conceptually simple, constitutes a tricky design problem. There are a number of practical requirements for a fibre-optic current source and failure to consider them can cause laser and/or optical component destruction.
Enclosure and Process Cooling is a guide book from Rittal that provides information on a variety of topics, including the basic principles of climate control, energy-saving opportunities and project planning, installation and operation — even for more complex applications. The book answers many questions that are of interest to original equipment manufacturers, panel builders and end users.
In today’s advanced global market, the need for new products to look, perform and function in a truly differentiated way has never been more important. Goods that fall back into a commodity bracket earn substantially lower profit margins, are subject to fierce competition and follow resource-sapping demands to evolve on short aggressive time scales.
Portable appliance testing (PAT) is the visual examination and electrical testing of portable electrical equipment used in industrial, commercial or public access areas and locations (including rented property) to ensure they are safe to use, and cannot present an electrical hazard to the operator or anyone in their vicinity. Megger has published a short guide to PAT testing.
There has been significant progress in high-precision, instrumentation-grade digital-to-analogue conversion. Previously, 12-bit digital-to-analogue converters (DACs) were considered premium devices. Today, 16-bit DACs are available and are increasingly common in system design. These are true precision devices with less than 1LSB linearity error and 1ppm/°C drift. Nonetheless, there are DAC applications that require even higher performance. Automatic test equipment, instruments, calibration ...
This application note is the fifth in a series that excerpts useful circuits from Linear Technology magazine to preserve them for posterity. This application note highlights data conversion, interface and signal-conditioning circuits from issue VI:1 through issue VIII:4. Like its predecessor, AN67, this application note includes circuits for high-speed video, interface and hot-swap circuits, active RC and switched capacitor filter circuitry and a variety of data conversion ...
This booklet from Megger, entitled ‘A guide to low-resistance testing’, is designed to help the engineer, technician or operator understand the rationale behind low-resistance testing; understand how to make a low-resistance measurement; understand how to select the proper instrument for the testing application; and understand how to interpret and use the results.
