Configurable distribution amplifier (D/A). Four independent 1 x 4 D/A's are integrated within the 1RU chassis. What makes the unique is the ability to bridge adjacent 1x4 blocks to make a larger D/A. In its default configuration, the CVD-144's four 1x4 D/A's operate independently. By simply flipping the bridge switches, adjacent 1x4 D/A's are bridged together and the input of the first block is sent to all of the bridged outputs allowing many different configurations to suit signal distribution needs.
