A/D Boards

United Electronic Industries (UEI) (Walpole, MA) has announced the release of four new analog input boards. All four of the boards offer 8 analog input channels, 24-bit A/D resolution and 120 kilosample/second maximum sampling rates. All four boards also offer complete, 350 Vrms channel-to-channel and channel- to-chassis isolation. The DNR versions are for use with the company’s RACKtangle® chassis, while the DNA versions are designed for installation into the PowerDNA Cube chassis. The DNx-AI-218 offers a ±10 VDC input range suitable for most general purpose DAQ measurements while the DNx- AI-228-300’s ±300 VDC input range makes it a good solution for a host of high voltage applications including battery testing, power plant monitoring, aircraft power monitoring and more.

Point-of-Load Power Management

The requirements for smaller size, lower weight, and reduced cost in space and defense systems are driving demands for improved power-management solutions. Integrated DCto- DC converters that are designed for hi-rel applications, such as POL buck regulators, offer considerably smaller size and lighter weight than similar multi-chip technologies. The use of a single chip improves reliability issues related to assembly and, with these single- chip POL buck regulators, system designers benefit from improved efficiency and design flexibility.

Beam Irradiance on Target System (BITS)

The Beam Irradiance on Target System (BITS) is a high energy laser (HEL) sensor array that directly measures the beam irradiance profile of HEL weapons. The BITS is a sensor array composed of 105 sensors arranged in a hexagonal pattern over a circular area and it is designed to withstand direct exposure to continuous wave (CW) lasers at threat irradiance levels. The sensor array spatially and temporally samples HEL beam profiles and is the only reusable and direct (on target) measurement system of its type. The BITS represents the state-of-the-art in directed energy test and evaluation HEL sensors.

Designing Rugged, Standards-Based Embedded Solutions

It can be argued that small form factor design trends are paradoxical. As form factor size decreases, functionality requirements increase; as processing power requirements heighten, lower power consumption and thermal output is expected. Add to that the requirement for ruggedness to accommodate for the shock, vibration, humidity, and temperature extremes and variance inherent in mobile and outdoor applications, and designers are faced with a very complex soup.

Tips for Selecting or Designing a Membrane Switch

Membrane switches are known for standing up to tough environmental conditions. Flexible and durable, the membrane switch can be customized with embossing, backlighting, sealing, and electrostatic discharge (ESD) shielding. Membrane switches can be made with either tactile or non-tactile feedback and they can be integrated with LEDs and other components. To get the switch that works for your application, follow these simple guidelines.

Pursuing Agile Signals in a Crowded Spectral Environment

For the capable RF engineer, continuous- wave (CW) and predictably repeating signals are no great challenge. However, design and troubleshooting become difficult when dealing with agile signals, and the challenges grow when these signals exist in an environment densely populated with similarly agile signals. Examples include applications such as radar, electronic warfare, wireless connectivity, and wireless communications. Indeed, some engineering jobs must be performed where two or more of these technologies intersect — sometimes accidentally and sometimes deliberately.
