  • Shielding Effectiveness Test

    Keystone Compliance

    Shielding effectiveness testing determines the ability of material to reduce the electromagnetic field in a space by blocking the field with barriers made of conductive and/or magnetic materials. Shielding effectiveness testing can be applied to a broad range of radio frequencies. Electromagnetic Shielding is typically applied to both enclosures and cables. The shielding can reduce the coupling or radio waves, electromagnetic fields and electrostatic fields. The amount of reduction can vary based on the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest. Also impacting the effectiveness of the shielding is the size, shape and orientation or apertures in a shield to an incident electromagnetic field. Electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as RF Shielding.

  • Lens Antennas

    ERAVANT

    A lens antenna is a directional antenna that uses a shaped piece of microwave-transparent material to bend and focus microwaves by refraction, as an optical lens does for light.[1] Typically it consists of a small feed antenna such as a patch antenna or horn antenna which radiates radio waves, with a piece of dielectric or composite material in front which functions as a converging lens to collimate the radio waves into a beam.[2] Conversely, in a receiving antenna the lens focuses the incoming radio waves onto the feed antenna, which converts them to electric currents which are delivered to a radio receiver. They can also be fed by an array of feed antennas, called a focal plane array (FPA), to create more complicated radiation patterns.

  • Nuclear Event Detectors

    DDC Connectivity Power Controls

    DDC's radiation-hardened, hybrid, Nuclear Event Detectors (NED) sense ionizing radiation pulses generated by a nuclear event, such as the detonation of a nuclear weapon, and rapidly switches its output from the normal high state to a low state with a propagation delay time of less than 20ns. The active low Nuclear Event Detection signal (NED) is used to initiate a wide variety of circumvention functions, thus preventing upset and burnout of electronic components. The NED output is also used to initiate both hardware and software recovery. This high-speed, 14-pin hybrid detector is used in electronic systems as a general-purpose circumvention device to protect memory, stop data processing, and drive power supply switches as well as signal clamps.

  • Thickness Check Calix

    LAP GmbH

    For the manufacturing of a perfect cold strip, many factors are crucial. Our measuring frames specifically check the thickness-related quality parameters of the strip steel or steel sheet. Free of radioactive radiation, laser sensors are used in the cold strip areas that do not require protection measures with laser class 2, or only low precautions when using laser class 3B sensors. The installation of our measurement systems is quick and uncomplicated for our customers. The CALIX is integrated into the line with its C-shaped frame across the material flow. Our solutions with and without traversing determine all important parameters for quality assurance, including strip thickness, edge thickness, wedge or cambering, and measure the complete thickness profile. Thus, you have full process control in the current production.

  • Car-to-X Signal Strength Emulator

    Qosmotec Software Solutions GmbH

    QPER-C2X is a special adaptation of the signal strength emulator QPER, designed for mobile and Vehicular Ad-hoc Networks (MANet and VANet). Every radio devices in such an infrastructure-less network acts as a sender, receiver, and forwarder (router). Therefore, the ports of the QPER-C2X hardware are fully connected with each other by dynamically controllable attenuators. The system is fully designed for frequencies up to 6 GHz, since wireless communication for Intelligent Transport Systems (ITS) is based on the WLAN standard IEE 802.11p from 5.850 MHz to 5.925 MHz. The connected ITS stations can be either on-board units, as they are built into cars, or road side units that are used by road infrastructure (traffic lights, road work area delimiters, velocity signs). For tests in the lab, radio modules of such ITS stations are each kept in a shielding box that prevents any unwanted radiation over the air.
