The display power supply provides the following:

All of the above

The display power supply in a radar system is responsible for providing power to various components of the display unit. These components may include logic circuits, analog circuits, sweep circuits, and the CRT (Cathode-Ray Tube) high-voltage anode.

"5 volts DC for logic circuits": Logic circuits in the display unit typically require a low voltage supply, commonly around 5 volts DC, to power digital components such as microprocessors, memory, and other digital logic devices.

"± 12 volts DC for analog and sweep circuits": Analog and sweep circuits often require dual power supplies, usually around ±12 volts DC, to power operational amplifiers, analog signal conditioning circuits, and sweep generators.

"17kV DC for the CRT HV anode": The CRT in a radar display requires a high-voltage supply to accelerate electrons and create the visual display on the screen. The high-voltage anode voltage can be as high as 17,000 volts DC to accelerate the electrons sufficiently to produce a bright and clear display.

The display power supply is designed to provide these various voltage levels to different components, ensuring proper operation of the display unit in a radar system. Therefore, the correct answer is "All of the above" because the display power supply provides the required voltages for logic circuits, analog and sweep circuits, and the CRT high-voltage anode.
