In early 2012, engineers at a prime aerospace manufacturer were assigned the task of replacing several existing integrated test adapters (ITAs) used to test multiple line replaceable units (LRUs) belonging to an Air Force program. One goal was to replace the existing ITAs with as much commercial off-the-shelf (COTS) technology as possible.

For multi-channel data acquisition systems, getting the correct readings in the correct timed order is crucial. System designers have two options for acquiring data in a deterministic fashion. They can use a real-time operating system (RTOS), that has a known buffer delay/ processing order or acquire data with a time-stamp for every sample and use precise hardware triggers and an accurate clock.
EXLab Express is a powerful, easy to use, plug and play data acquisition software package that allows users of the EX1401 Thermocouple/Voltage Measurement Instrument to acquire data without programming. But, not only is it powerful and easy to use, it's free!
To select the right power source for your applications, one of the first things that you must do is to figure out how much output power you need. For a DC supply, this is relatively straightforward. You first determine the highest output voltage you'll need and then the highest output current that you'll need. The output power (in watts) is equal to the output voltage times the output current:
The power supply may be one of the least-considered components of an electronic system. After all, how hard can it be to find the right power source for your system? You figure out how much current you need at the voltage your system will operate at, find a model that can supply that voltage and current in a catalog or on a website, then make the purchase.
The Elgar GUPS Series of uninterruptible power supplies are ruggedized on-line UPSs that accept a broad range of worldwide utility and military AC input power. Without operator intervention, they automatically select the appropriate input power ranges to accommodate global operation. The batteries used in the GUPS Series units are a spiral wound, valve-regulated, lead-acid batteries. While the unit itself maximizes battery life with automatic, microprocessor-controlled equalization and temperature compensation during charging, there are steps that users can take to extend UPS battery life even more.
