R&S SLG
2 Brief Introduction
2.1 Features
The R&S SLG has a frequency range from 250 to 3000 MHz, covering all satellite IF
frequency bands used worldwide. The 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 interface. Each
channel can contain an ARB waveform or a CW carrier instead of a TV signal.
The SLG is primarily intended for performing RF tests on satellite TV components. It
has all interfaces commonly used in consumer electronics and professional satellite
electronics, and is just as suitable for testing tuners and set-top boxes as it is for
testing upconverters, amplifiers and satellite payloads. Thanks to its ability to
simultaneously generate multiple channels with high symbol rates, the SLG is also
ideal for performing stress tests on systems that process large data quantities, such as
transcoders, conditional access middleware and military surveillance data processing
systems.
The SLG can be fully remote-controlled, making it ideal for integration into automatic
test systems. All this functionality has been packed into a compact 19" 1U instrument,
effectively replacing the previously required rack full of modulators.
