What outputs does the power supply card (A3A4) deliver?

The power supply card (A3A4) is specifically designed to provide the necessary operating voltages for the radar system to function correctly. By delivering triple output power of 5, 12, and -12 VDC, it ensures that various components of the radar system can operate at their required voltage levels. This is critical because different electronic parts may require different voltages for optimal performance. The specific voltages supplied correspond to the operational needs of the hardware used within the radar, enabling the entire system to work efficiently.

In the context of radar systems, having the correct power supply is crucial as it directly affects the functionality and stability of the system. The various components may utilize these voltages for different purposes, such as signal processing, amplification, or other operational functions critical to radar capabilities.

The other options mention aspects that are not directly related to the function of the power supply card. For example, cyclic signals for timing control and frequency modulation outputs pertain more to the signal processing side rather than power supply. Signal noise cancellation outputs also relate to signal integrity rather than power delivery. Therefore, option B accurately captures the primary function of the power supply card in providing stable and essential power outputs for the radar system's operation.
