Product Introduction
The 8-channel Radi
L
ink
®
is designed for broadband emission measurements. Its basic
function is to transfer small-signal RF signals from a fully electrically isolated remote unit
to a measurement system.
The Radi
L
ink
®
system is typically used to replace coaxial connections in RF
measurements setups. Where coaxial cables introduce losses that increase with
frequency and length of the cable, the Radi
L
ink
®
provides a stable RF-link with little
frequency response. Due to the use of fibre optics the influence of cable lengths is
reduced to a minimum. Furthermore, common mode currents flowing through shields
of coaxial cables, are eliminated by the use of this fibre system.
This 8-channel Radi
L
ink
®
system is a special version designed for automotive
measurements using and analogue fibre optic link. Due to the multi-channel setup,
there is no need to alter the test setup between measurements. The 8 channels are
designed to provide bias supply for active antennas. This bias supply can be generated
by the Radi
L
ink
®
itself or applied by external devices.
The Radi
L
ink
®
system consists of two parts: the 8-channel remote unit (product code
RLK2008A) and a plug-in card for the Radi
C
entre
®
models (product code RLK2003A). A
duplex fiber connects the remote unit to the plug-in card.
Applications for the Radi
L
ink
®
are:
•
General emission measurements
•
Measurements according to CISPR25
