RadiLink
The unique Analong Glasfiberlink for EMC-measurements
Low Loss - High dynamic range - Broadband
The RadiLink ® is an analog fiber optical link with high dynamic range of 85 dB and a bandwidth of 9 kHz to 3 GHz. This makes the optical link ideal for the use in EMC test environments. The optical link can be used to replace the coaxial cable.
Low Loss (gain)
Coaxial cables typically have a loss in between 0,1 dB and 1 dB per meter depending on the type/quality of cable and the frequency. Certainly in applications at higher frequency and with long cables, like in a large EMC chamber of at an Open Area Test Site, the signal loss on the cable will result into large measurement errors. The RadiLink® RF optical link is the solution to this problem and provides a small gain and therefore will solve the loss problems on the coaxial cable.
High Dynamic Range
With regular fiber optic links the dynamic range is too low for use in EMC applications. The RadiLink® RF optical link provides an unprecedented 85 dB dynamic range suitable for almost all EMC apllications. In fact the high dynamic range in combination with the low loss will improve the performance of most EMI measurement receivers.
