The Analog/Digital Signal Combiner is a compact module designed to be installed into one of the slots on the RTM of the Radar Processor/Display. This module converts the clutter and interference generated by the DSP of the RTM to analog format, and adds it to the I- and Q-channel echo signals coming from the Radar Receiver.

The Analog/Digital Signal Combiner has two BNC-connector inputs to receive the I- and Q-channel echo signals. It also has four BNC-connector outputs. Two outputs provide the clutter and interference signals added to the I- and Q-channel echo signals. The other two outputs provide the I- and Q-channel, perturbed echo signals. All these inputs and outputs are protected from misconnections within the system. Test points are available on the module's front panel to observe all these signals using a conventional oscilloscope.

DC power is automatically supplied to the Analog/Digital Signal Combiner when it is installed into the RTM.
