User Manual CXE180 59300401 Rev.001 26.5.2010 10(12) Adjustments Downstream signal path The output stage uses a GaAs hybrid to improve RF performance over the entire 47 to 1006 MHz passband. The distribution path, through the use of plug- in output modules (Figure 4 pos.11), can be set up for a variety of output configurations. -
