- DARE!! Instruments introduced its first analogue optical RF link for the automotive industry more than 15 years ago. This analogue fiber optic link replaces the coaxial cable with emission measurements, so that undesirable effects, due to the measuring cables, are put in the past. Various leading car manufacturers use the RadiLink for broadband emission measurements on antennas in a vehicle.
- With the increasing demands and technological developments in a modern-day vehicle, the need arose to further expand and improve the RadiLink functionality. For example, a modern vehicle uses various antennas, including radio (AM, FM, DAB +), TV (UHF, VHF, DVB-T), GPS and communication (GSM, WiFi, Bluetooth). In order to be able to properly measure emission disturbances of all these different antennas in the vehicle, DARE!! Instruments developed the new RadiLink 8-channel analog fiber optic RF link.
- RadiLink 8 channel system :
+ A RadiLink system consists of a RadiLink RLK2003A plug-in card and an 8-channel remote unit RLK2008A. The frequency range of the RadiLink runs from 9 kHz to 6 GHz, covering the frequency range of all different antennas in a vehicle. The remote unit placed in the vehicle has a small size of 170 mm x 45 mm x 82 mm (L x H x D) and is equipped with 8 high-frequency inputs (type SMA) for connecting the antenna signals.
+ In the case of active antennas, the antenna can be supplied from the RadiLink through an internal bias voltage (adjustable from 5.0 to 12.0 Volts), optionally this bias voltage can be offered externally. The RadiLink plug-in card is placed in the RadiCentre modular and multifunctional test system and is connected to the RLK2008A via a supplied 25-meter-length duplex fiber optic cable.
- Built-in battery and preamplifier : The RadiLink RLK2008A is equipped with an internal battery and pre-amplifier. The Li-ION type battery makes it possible to do RF emission measurements in complete 'OFF' mode of the vehicle. The batteries can be charged with the included charging unit and have sufficient capacity to carry out measurements for a period of 3 hours. Of course, the RLK2008A can also be powered by means of the battery in the vehicle, for which the RadiLink is equipped with a LEMO connection. The built-in pre-amplifier has a gain of 20 dB, making it possible to amplify low emission signals so that they can be measured well with a receiver.
