Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC Transmitter/Regenerative Translator Board Descriptions of 470 to 860 MHz. The pallets operate Class AB and generate approximately 230 Watts ATSC with an input of 8 Watts ATSC. (A6) 2 Way Combiner Board (1313155), in amplifier drawer w/two Dual 888A Pallets The 2 way combiner board takes the two RF Inputs at J4 & J5 (≈230Watts ATSC) on the board and combines them to a single output (≈375Watts) at J1 that connects to J2 the 7/16” (1.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC Transmitter/Regenerative Translator Appendix A: System & Drawers Drawings and Parts List System Set Up Procedure This system was aligned at the factory and should not require additional adjustments to achieve normal operation. This Innovator CX Series system is of a drawer design with multiple boards inside the drawer. If a board fails, that board needs to be changed out with a replacement board. The failed board can then be sent back to Axcera for repair.
