The Ranatec RT-650 can be equipped with up to four (4) independent fading channels. Each channel emulates multipath fading according to Rummler’s model which is relevant for microwave radio links. Full remote control is enabled via a standard LAN connection. A built-in C/N generator is available as option to insert noise into the radio path. The C/N generator function measures the modulated carrier power and adjust the AWGN so the wanted C/N0 ratio is obtained. The C/N generator function is implemented in the digital domain of an FPGA, which gives unprecedented accuracy of the set C/N0 ratio.
