What is the first step in tracing the AFLCS signal path?

The first step in tracing the AFLCS signal path involves starting from the power box to the modem. This step is crucial because the power box is responsible for supplying power and initializing the modem, which then communicates with other components in the system. By starting from the power box, you can ensure that the modem receives power and is functioning correctly before moving on to trace the signal further, which would involve examining connections to the antenna and VIDS. Understanding this order is essential to diagnosing any issues in the signal path effectively, as power supply and functionality should be verified before proceeding to check signal transmission quality between other devices.
