The R&S CLG cable load generator is a multichannel signal generator for cable TV signals. It is the world's first instrument to simulate cable TV networks with full channel loading. The R&S CLG generates both digital and analog TV signals. These signals can be freely combined, allowing users to simulate any conceivable channel loading scenario in the lab.
