GL Communications Inc.
Communications is dramatically changing right now, as “mobility” and “IP” technologies such as LTE, Advanced LTE, WiMax, 3G, and Broadband Internet, lead this transformation. As these technologies are rolled out, basic voice/video/data quality will ultimately determine the fate of carriers and end equipment manufacturers. Simple and effective methods of testing voice, video, and data are sorely needed - GL’s Voice, Video, and Data Quality Test Solution provides this flexibility of connecting to and between any network, any service, and any interface.

Infotainment Test Device ITD 1024 -
NOFFZ Computer Technik GmbH
The complexity, cost and weight of audio systems are significantly reduced with the Automotive Audio Bus (A 2 B ® ) from Analog Devices Inc. Regardless of their hierarchical structure or use as master or slave, all A 2 B ® products must be adequately tested before use. This applies, for example, to HiFi amplifiers/loudspeakers, head units, eCall systems, microphones, vibration/noise suppression units, actuators or sensors.Our small and very compact infotainment test system ITD 1024 takes on this task for you: It comprehensively and extremely reliably tests all A 2 B ® signals and communication in all phases of the product development process - during development, for validation and in production.

Focus Microwaves
All Focus tuners use extremely efficient calibration and tuning algorithms and control electronics based on LAN control (iTuner). This is a merger our proven tuner technology with state of the art control electronics to create the latest tuner generation. The on-board micro-processor and tuning firmware form a self-contained and fully calibrated test instrument. The micro-processor inside the tuner accepts ASCII format communication, via an industry standard TCP/IP interface, controls up to nine stepper motors (tuner axes) and executes interpolation and tuning functions for single probe (CCMT) tuners (one probe per frequency range). For tuners with more than one independent probe (MPT) covering the same frequency range to allow for harmonic tuning, external computing power is required, because of the exponentially growing number of combinations of tuner states (slug positions).

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.
