Which MSSR subassembly injects the self-test pulse into each receiver?

• A. Transmitter interface
• B. Receiver interface
• C. Plot Processor
• D. Display Console

Answer: (A)

The self-test pulse must be introduced into the receiver chain to exercise and verify every receiver’s performance. The component that links the transmitter side to the receivers and has the paths to route signals into each receiver is the transmitter interface. It can generate the known test pulse and distribute it to all receiver inputs, ensuring every receiver sees the same reference signal for a uniform, end-to-end check of gain, timing, and dynamic range. The other subassemblies aren’t responsible for injecting test signals: the receiver interface handles processing of actual received signals, the plot processor handles data processing, and the display console shows the results. So, the transmitter interface is the correct subassembly for injecting the self-test pulse into each receiver.
