Q

The display power supply provides the following:

🔍 Key Concepts

• Typical voltage levels used for digital logic circuits in marine electronics • Common supply voltages for analog and sweep circuits in radar displays • Whether a single power supply in a display unit often provides multiple DC voltage rails

💭 Think About

• Which option lists voltages that seem appropriate for logic-level electronics, rather than high‑power transmission circuits? • Does the pulse forming network usually require low‑voltage logic power or higher‑voltage energy storage for the transmitter? • Would one display power supply reasonably be designed to output all the different voltages listed, or is one set more consistent with internal electronics needs?

✅ Before You Answer

• Check which voltages are typical for TTL/CMOS logic (digital boards) in older marine radar/display equipment. • Consider what kind of circuits need bipolar (±) supply rails, and which option actually provides that. • Verify whether 18 V DC or 80 V AC are more likely associated with the high‑energy transmitter/antenna system rather than the low‑power display electronics.
