EM - PHANTOM -
Schmid & Partner Engineering AG
The POsable Phantom for Electromagnetic sYstems Evaluations (POPEYE) is an anatomically correct human phantom based on a torso shell w/ head with posable arms, hands and legs. This radio frequency (RF) human has been designed to meet the requirements for test configurations for which the effects of the body on the EM performance cannot be neglected, such as operating tablet and laptop computers and other body-mounted transmitters. With a simple adjustment (one tightening screw), the arms, hands and legs can be positioned accordingly for conducting simulations of any usage or operation (standing, sitting, arms raised, talking position, etc...).

Washington Laboratories LTD.
The implementation of digital control and monitoring systems in nuclear power plants drives EMC requirements for new and replacement equipment to be used in nuclear plants. For the past 20 years, the Electric Power Research Institute (EPRI) has been developing test methods to demonstrate compliance with EMC requirements. The methods and limits are called out in EPRI TR-102323. The first issue of this report was released in 1994 and the current revision (Revision 4) was released in 2013. The original report and basis included results from electromagnetic surveys at seven nuclear power plants in the United States.

EM-2107A | 30 MHz – 1.5 GHz -
Electro-Metrics Corp.
The EM-2107A is a standard test fixture for evaluation of the electromagnetic shielding effectiveness of planar material. The fixture is an enlarged section of coaxial transmission line and complies fully with the requirements of ASTM test method D4935-1. The measured data relates to the shielding effectiveness due to a plane wave (far field EM wave) from which near field values for magnetic and electric fields may be inferred. The EM-2107A is provided with a reference standard test specimen, a dynamic range specimen. Dynamic range of greater than 80dB is achievable, although the cables and other test system components usually establishes the limiting factors.

WSA -
Chuan Sheng Electronics Co., Ltd.
Due to environmental quality management and energy management, we've developed WSA, wind speed sensors which can be applied on ventilation systems, air conditioning, and negative pressure rooms. WSA is a high-accuracy duct type wind speed sensor which can quickly measure the small wind speed. It is stable, high-accurate, and with small drift only. Also, it can caculate the value of the current air volume depending on the measured cross-sectional area of the ducting. Ducting installation and screwless terminals help the users work more easily. Besides, the sensor is equipped with EMC anti-interference devices so that it can withstand strong electromagnetic interferences.

Com-Power Corporation
Com-Power broadband high gain preamplifiers were designed for electromagnetic interference (EMI) testing and certification. EMC test labs use preamplifiers to improve sensitivity of the test system during EMI radiated emissions measurements. Without a high gain preamplifier, signals picked by the antenna that have amplitudes below the noise floor of the test system cannot be measured. The preamplifier gain has minimum variations for the entire operating frequency range for accurate emissions measurements. The Com-Power preamplifiers were primarily intended for EMC applications. However, it can be used for other applications that require signal amplification.

Analog Devices Inc.
High supply voltage op amps are used in systems that demand the widest dynamic range with the best signal-to-noise ratio. Engineers turn to Analog Devices for high voltage amplifiers that deliver industry-leading performance. Increasingly, new high voltage amplifiers also offer features to improve system performance, cost, and robustness while easing the complexity of system design. New features include integrated input overvoltage protection (OVP), on-chip electromagnetic interference (EMI) filtering, higher electrostatic discharge (ESD) immunity, and greater resistance to latch-up in both powered and unpowered operations.
