There are CATV networks which operate in disctricts where effective demand for TV and data service is lower. In such cases the achieveable bandwidth with the order of GHz is not fully used, only up to 450 MHz. In this case the conventional gain and slope driver automatic controlled by the 29th channel (535,25 MHz) cannot be used. That is the reason, why a COMTECH customer ordered at us an ASG controller for 433 MHz. We have realized this new module, whose all other parameters are the same as the parameters of ASG535.
