The Sweep Generator Card (A3A2) produces which outputs when triggered by the sync trigger?

• A. Produces the reference sweep, the negative sweep gate, and the positive sweep gate when triggered by the sync trigger
• B. Converts RF energy to video signal
• C. Generates the master trigger for the transmitter
• D. Displays targets on the map-like presentation

Answer: (A)

When the sync trigger arrives, the Sweep Generator Card provides timing signals that coordinate the radar sweep. It outputs a reference sweep, which sets the baseline timing and shape of one sweep cycle, plus two gate signals—the negative sweep gate and the positive sweep gate—that define the active sweep window. These gates control when the sweep information is allowed to pass through, ensuring the transmitter/receiver and display stay in sync with the sweep waveform. This is what makes it the best choice: the card’s role is specifically to generate synchronized timing signals for the sweep, not to convert RF to video, generate the transmitter’s master trigger, or display targets. Those other functions belong to different parts of the system.
