GAO Tek Inc.
Radio Frequency Identification technology, commonly referred to as RFID, uses electromagnetic fields for the purposes of identifying and tracking objects. More recently, the technology has moved into mainstream applications that speed up the handling of manufactured goods and materials by attaching RFID tags to them. RFID technology has been around since the 1970s but its high cost and limited practical applications have discouraged its use up until recently.

Com-Power Corporation
Horn antennas can be used for emissions and immunity testing. These antennas are constructed using light weight aluminum with a corrosion resistant conductive coating for indoor or outdoor use. Each antenna is individually calibrated. The calibration data and certificate will be shipped with each antenna.The high gain reduces input power requirements to generate high electromagnetic field levels for immunity testing. High gain also increases antenna sensitivity to low level signals.

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.

TÜV SÜD Japan
SAR limits are there to protect all of us from wireless devices that exceed the transmit Radio Frequency (RF) threshold. SAR stands for Specific Absorption Rate. It's a measure of the rate at which energy is absorbed by your body when you are exposed to an RF electromagnetic field. In some countries, the SAR test result figure has to be displayed at the point of sale. To have a presence in these markets, your products must meet strict SAR regulations.

HIGH-POWER RADIO FREQUENCY (RF) AND MICROWAVE AMPLIFIERS, TWTA AND SOLID STATE -
Communications & Power Industries
electromagnetic compatibility (EMC) high-intensity radiated field (HIRF) testing, military testing, electronic warfare simulation and scientific applications are based on the same switched-mode power supply technology as its rugged amplifiers. As a result, these instrumentation amplifiers have all the same performance and reliability advantages as the rugged product line, but have been neatly re-packaged into compact, lightweight and affordable rack-mountable units more suitable for less demanding physical environments. CPI TMD's new modular design (the PTCM range) has many user benefits, including advanced self-diagnostics, ethernet interfaces, remote management, VSWR protection and plug and play field replaceable power supplies.

FIM-22 And FIM-41 -
Potomac Instruments, Inc.
The Models FIM-22 and FIM-41 are portable field strength meters designed to provide precise, direct measurements of electro-magnetic fields in the 200 kHz to 5.0 MHz spectrum. These units include a receiver, integral shielded loop antenna, precision attenuator, internal calibration source, and battery power supply. With calibration accuracy traceable to the National Institute of Standards and Technology, the FIM-22 and FIM-41 meet the most exacting requirements of government and industry. Their hinged covers, on the rugged drawn aluminum cases, contain a loop antenna. Opening the cover to a vertical position connects the antenna terminals to the receiver via maintenance-free gold-plated contacts. An interlock switch prevents inadvertent battery discharge when the cover is closed.

GAO Tek Inc.
RFID tags bring the future of technology to today. Radio-frequency Identification(RFID) tags can be placed on almost any piece of clothing, cash, animals and even humans. Tags use electromagnetic fields to identify and track the desired object. Active tags are powered by a battery located inside the tag, and may operate over hundreds of meters away from the RFID reader. RFID tags have been expanding ever since their inception – they became especially popular when used in toll readers and assembly lines to track the product’s progress throughout the assembly line.

Guangzhou Jumho Electric Co., Ltd.
Cell phones and other wireless devices radiate powerful electromagnetic fields that can cause interference and noise in microphone signals. The interference and noise is called RF interference, which is an unwanted “signal” that occurs at the same time and frequency as a data signal. The RF interference disrupts the flow of data and degrades quality-of-service. Jumho Electric provides a cost-effective RF interference test system for GSM interference level measurement of wireless microphone.
