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.

DVTest Inc.
The dbDIRECT Broadband Antenna features a broad frequency range of operation, high gain, small form factor and directional radiation pattern, making it highly attractive for widespread use in test and measurement of emerging wireless technology devices and radars. Contrary to conventional Vivaldi antennas limited to operating only at higher frequencies, the dbDIRECT Broadband Antenna design is optimized to operate at a frequency as low as 700 MHz up to 6 GHz. This lightweight and compact antenna design provides excellent matching over a broad frequency range.The antenna is designed to be placed in a DVTEST's portable anechoic chamber such as the dbSAFE enclosures for OTA (Over the Air) testing of DUTs. The antennas can be mounted in fixed positions to facilitate repeatable results. When used in conjunction with a rotary positioning mechanism, customers are able to detect the highest point of power sensitivity for enhanced accuracy and repeatability in measurements. In this configuration, both the antennas and DUTs can be positioned in order to facilitate the measurement.

Shenzhen Setec Power Co., Ltd.
Solar pumping system is composed of a solar array,a pump and a solar pumping inverter. Based on the design philosophy that it is better to store water than electricity , there is no energy storing device such as storebattery in the system. The solar array,an aggregation of many solar modules connected in series and parallel , absorbs sunlight radiation and converts it into electrical energy , providing dynamical water for the whole system. The pumping inverter controls and adjusts the system operation and converts the DC produced by solar array into AC to drive the pump , and adjust the output frequency intensity to realize the maximumpower point tracking (MPPT) . The pump, drive by 3-phase AC motor,can draw water fromthe deep wells or rivers and lakes to pour into the storage tank or reservoir , or directly connect to the irrigation system ,fountain system,ect. According to the actual systemdemand and installation conditions,different types of pump such as centrifugal pump, axial flow pump,mixed-flow pump or deep-well pump can be used.

To measure light radiation’s spectral characteristics, Instrument Systems optical spectroradiometers are the instruments of choice. Instrument Systems has a variety of optical spectroradiometers to meet any user’s needs or budget. Instrument Systems Spectrometers mainly measure UV-VIS spectroradiometry, luminous flux, LED production and LED radiation levels. More importantly, they provide these measurements at a fast rate, gathering data very quickly and efficiently. A number of models come with innovative features that allow the systems to be used universally in a broad range of applications and functions. These systems conveniently change into spectroradiometers when users attach absolute calibration and optical probes. It’s critical that these units maintain a high degree of accuracy and quality in order to return precise calculations of colorimetric, photometric and radiometric data through the built-in software. For these and other reasons, Instrument Systems continues to expand the leading edge of technology by committing the majority of its Research & Development work to this field.

If you need assistance measuring angle dependent spectral measurements, Instrument Systems has developed a comprehensive line of goniophotometers to meet your needs. Instrument Systems Goniophotometers are used to analyze angle dependent spatial radiation properties of SSL lamps and LED modules. Instrument Systems has two varieties of goniophotometers, one used for Large SSL lamps and LED modules as well as one designed for use in small to medium SSL Luminaries and LED modules. These instruments are capable of exporting data in an easily readable EULUMDAT format and provide exceptionally accurate measurement of luminous intensity distribution and luminous flux. The LGS 1000 model has an optional addition of a luminous flux integrator. Instrument Systems also offers a Type C Design for that particular goniophotometer model which is designed with a horizontal optical axis. This makes setting up a measuring path much simpler and allows measurements for specimens up to 1900mm in diameter.

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.

AR700 -
Scope T&M Pvt, Ltd.
PD Defect Location in High-Voltage Equipment Insulation by Acoustic Sensors To act on deteriorating insulation the source of PD must be known.The insulation defects produce partial discharges, which emits electrical impulses, radiation of electromagnetic waves as well as acoustic signals.The AR700 measures acoustic signals with multiple sensors spread over the transformer. Then the software determines the failure location using the time difference of all incoming signals. Finally, these coordinates are shown in a 3D model of the transformer. AR700 device is used for measuring of acoustic signals on the external surfaces of gas-insulated breakers and substations, power transformers and other tank high-voltage equipment. The acoustic signals are caused by partial discharges in the insulation, which is the sigh of the defects.The advantage of “AR700” device is the quick installation of the acoustic PD sensors on the external surface of high-voltage equipment tank. The sensors have magnetic holder that is why there is no need to de-energize the equipment for the sensors installation. “AR700” device has 4 syn-chronic channels for acoustic signal measurement. This gives the possibility not only to find the defects in the insulation, but also to locate them. The location function of the “AR700”device is unique for acoustic devices.
