The R&S SLG satellite load generator is a multichannel signal generator for digital satellite TV. It is the world's first integrated instrument to simulate TV satellite bands with full channel loading. The R&S SLG generates satellite TV signals with different standards and parameters and combines them in any desired manner. Users can simulate any conceivable uplink and downlink configurations in the lab. The R&S SLG has a frequency range from 950 to 3000MHz, covering all satellite IF frequency bands used worldwide. The R&S SLG can simultaneously generate up to 32 digital satellite TV transponders in line with DVB-S/S2 and ISDB-S/S2, or a transponder in line with DVB-S2 wideband. Up to 16 transponders transmit externally fed transport streams; the other transponders carry internally generated PRBS data. The transport streams are fed into the instrument via an IP or ASI interace. Each channel can contain an ARB waveform or a CW carrier instead of a TV signal.
