Com-Power Corporation
A typical emi emission test is performed using broadband EMC antennas such as biconical, log periodics, Combilogs and horns. These antennas usually placed at 1, 3 or 10 meter distance as required by the test specification. These is considered far field measurements and the emission limits are given for the specific distance by the specification. During EMI compliance measurements, the emissions levels from products are compared with these limits. If the product exceeds these limits it is considered failing. These tests are typically conducted in a open area test site IOATS) or inside an anechoic chamber.

Framos Technologies d.o.o.
FRAMOS is the first company in the market to integrate Analog Devices’s new GMSL3 technology into an embedded vision environment. GMSL3 can transmit high frame rates (4K, 90 fps) as far as 14 meters with unprecedented efficiency. This interface is well suited for applications where the MIPI CSI-2 (D-PHY) length restrictions are not sufficient, while at the same time, a highly durable cable with low power consumption and low cost are essential. Camera developers can use the flexible FRAMOS Sensor Module Ecosystem to validate a variety of image sensors in the lab and in the field while taking advantage of the interface’s features.

Cuming-Lehman Chambers
Most antenna measurements need to be carried out in the far field; that is, the test antenna should be illuminated by a plane wave. Typically this is carried out by providing sufficient separation between the source and the AUT so the spherical wave approaches a plane-wave character.Near-Field chambers are an excellent alternative to traditional far-field ranges; testing that can be accomplished on a far-field range can be accomplished on a Near-Field test range. This method of testing allows an operator to employ an indoor anechoic test chamber at a reasonable cost and avoid the problems associated with weather and security concerns often encountered when using an outdoor test range.

OptiCool® -
Quantum Design Inc.
The OptiCool by Quantum Design is a new optical cryostat using an innovative design that puts the sample volume in the heart of your optical environment. A custom 3.8 inch bore, split-coil, conical magnet offers fields perpendicular to the optical table up to ±7 tesla. The highly integrated design means, even with a magnet, your sample isn’t buried inside a large cryostat, far away from the optics. Seven side optical ports and one top optical port allow for optical access to your sample from a wide array of directions.

KoCoS Messtechnik AG
Dramatic advances in the field of measurement technology and the use of state-of-the-art micro-electronics have led to the development of a new generation of electricity meters which are far more accurate than their predecessors of just a few years ago. As well as measuring the exact amount of energy used, a high level of integration enables electronic meters to perform a number of additional functions. As a result, these meters are also more sensitive to network irregularities. This means that regular testing is the only way to ensure that a meter functions correctly, both during final factory tests and during the entire life span of a meter.

Signals & Systems India Private Limited
The IRIG-B TTL signal is a time synchronization protocol that can be transmitted up to 50m maximum using coaxial cable. So the relay which is to be received the IRIG-B TTL signal may be far away from the IRIG-B source. The relay may be not able to synchronize with the GPS. To avoid such an incident in the field, some of the relays have provision to receive IRIG-B RS485 signal. The IRIG-B RS485 signal can able travel up to 1200m without any booster. All Time source equipment may not be supplied with IRIG-B RS485 signal output. The converter will act as a bridge between GPS Time source and Relays for time synchronization.

Teledyne Marine Benthos
The Benthos Directional Acoustic Transponder (DAT) is anextension to the Teledyne Benthos ATM-900 Series modem, which automatically estimates the azimuthal and vertical arrival angles of a message sent by a remote modem. The system is a modified ultra-short baseline (USBL) which uses a broadband component of a typical modem message to form estimates of arrival angle(s). While conventional USBL devices employ tonal signals, our appropriate processing of wide band signals provides far better combined range and arrival angle estimation, especially at low Signal to Noise Ratio (SNR). Our device offers a clear 360 degree field of view in azimuth, and an approximate vertical coverage spanning + 90º overhead to -50º below horizontal.

MVG
A Compact Antenna Test Range (CATR) allows electrically large antennas to be measured at a significantly shorter distance than would be necessary in a traditional far-field test range. Compact ranges use a source antenna (feed) to radiate a spherical wave in the direction of a parabolic reflector, collimating it into a planar wave for aperture illumination of a Device under Test (DUT). It's lowest operational frequency is determined by the size of the reflector, its edge treatment and the absorbers. The two edge treatments available are serrated edge for general purpose applications, and rolled edge to achieve higher accuracy for special applications. Multiple-feed systems may be used to improve the far-field characteristics. A compact range test system also allows system level testing of a complete device architecture.

Thorlabs, Inc.
Thorlabs' Mode-Conditioned Light Sources are fiber-coupled LED sources that have an output with a flat-top profile in the far field. Common applications include the testing of multimode fused fiber components as well as verification of modal behavior in fiber-based setups. Standard fiber-coupled LED sources can have a range of output profiles that are usually not uniform and vary from source to source. This can be dependent on emitter orientation, alignment with fiber tip, and connector assembly. These mode-conditioned sources have been engineered to distribute light evenly into all transverse modes, resulting in an equilibrium modal distribution at the output. The front panel includes an adjustment knob to control the power and an output port that accepts 2.2 mm wide-key FC/PC connectors. A DS15 15 V power supply with a location-specific plug is included with each device.

F-Series -
Emite Ingeniería SL. Ed
The F large-size hybrid Reverberation/Anechoic Chamber represents the most versatile OTA test system in the market today. With the same unique test features of their E Series RC counterparts, the F-Series can also test large form-factor devices under test (DUTs) like laptops, large TV sets, solar and trash compactors, drones, fridges or washing and vending machines, among others. With up to 16x16, 8DLCC and DUTs up to 2m and 500 kg including full-body phantoms in a turntable, the F Series also expands the frequency range down to cover 200 MHz up to 40 GHz frequency ranges and the test modes to include EMC, BS, small cell, eNodeB and Virtual Drive Testing over the air (VDT-OTA). In an again unheard-of feature, the F-Series is also reverse-convertible into an Anechoic chamber, allowing Far Field (FF) and Spherical Near Field (SNF) radiation patterns, efficiency and gain measurements and pre-5G testing of antennas and devices. Conversion from RC to AC or vice versa can be performed within half a day.

CATR Radar Test System UTP 5069 -
NOFFZ Computer Technik GmbH
Modern driver assistance systems must recognize increasingly complex traffic scenarios and convert them into appropriate vehicle reactions with the help of artificial intelligence (AI) and specific algorithms. Imaging radar sensors with a higher spatial resolution, so-called imaging radar sensors, are therefore required. These can better distinguish larger from smaller objects and, due to the larger antenna apertures, also require larger dimensions of the test environment or larger far-field distances. Testing these sensors in the direct far field ( UTP 5065 ) would therefore require very large absorber chambers up to ten meters in size and more.Our efficient test system UTP 5069 offers exactly the right solution:By using CATR technology (Compact Antenna Test Range), 4D, imaging and other radar sensors with large far-field distances are calibrated with high precision in a small footprint. With the extremely low-reflection NOFFZ absorber chamber, the system is very well suited not only for validation, but also for EOL tests.
