Hi Group, A satellite (range 10-14GHz) consists of two parts, the modulation unit (IDU= in door unit) and the RF unit (ODU= out door unit). The two units are connected together with a coaxial cable which can be up to 100m long and it carry the IF signal of a couple hundreds MHz. The ODU consists of an up-converter, amplifier, antenna and so on, while the IDU is the modulator/demodulator, power unit and generating the IF signal.
We assume (for sure) that the complete system is covered by RTTE. But the IDU will also be available as a stand-alone unit on the marked. No teleterminal connections are available from the IDU, only RS-232 input and IF output on coax cable to the ODU. Our question is: For the IDU, will RTTE apply or will only EMC (and LVD) apply, as a stand-alone unit? We feel this system looks like a broadband TV-cable system. You have a RF transmitter, but it only transmits via cable. No harm on the RF spectrum.
