Rohde & Schwarz's CLG cable load generator is a multichannel signal generator for cable TV signals that operates in the 47 MHz to 1002 MHz frequency range. It features up to 119 channels for European cable television, and up to 158 channels for US cable television. Users are able to simulate any possible channel loading scenario in the lab due to the CLG’s ability to generate freely combined digital and analog TV signals.
The R&S®CLG is primarily intended for testing cable TV receivers and cable tuners. It can also be used to test CATV amplifiers. If linearity demands on the device under test (DUT) are very high, an external bandstop filter may have to be used to improve the signal-to-noise ratio. The R&S®CLG can be fully remote controlled, making it ideal for integration into automatic test systems. All this functionality has been packed into a compact instrument that is only 19 inch wide and one HU high. To generate as many TV signals as those delivered by the R&S®CLG previously required a rack full of generators.
