Microwaves & Mechanics: Are You Ready for the DP CPD Quiz 46?
First, the Principle of Operation section mentions that the system uses low-energy microwaves, antenna tracking between fixed and mobile stations, servo motors driven by the signal difference, and the use of continuous wave link. Possible questions here could cover how the system determines range/bearing, components like servo motors, or the type of microwave link used.
Looking at Range and Accuracy, there’s a distinction between the standard and beacon systems. The standard system has higher accuracy (1m vs 1m for beacon, but beacon’s azimuth accuracy is dependent on other factors). Also, beacon system’s range depends on antenna type. The system is unaffected by weather but has issues with reflections causing interference zones. Lower antenna positions have narrower interference zones. Questions here might compare standard vs beacon systems, factors affecting interference, or antenna height impacts.

For operation of multiple systems, frequency pairs, address codes, and placement (vertical vs horizontal distance) are important. Questions could ask about avoiding interference, frequency pairs being 30 MHz apart, or address code functions.
Installation procedures for mobile and fixed stations: line of sight requirements, avoiding radar antenna same plane, alignment procedures using telescopes, entering reference bearings (0 or 180). Questions might test alignment steps, why certain installations are avoided, or the purpose of the telescope.
In the Influence of Antenna Height, lower positions are preferable because interference zones are closer and narrower. A question here could be about why lower positions are better.
Operation section mentions control software components and master system control. Maybe a question about how many control panels can be active or which system has full control.

From Theory to Practice: Tackle the DP CPD Quiz 46 Challenge!
Ensuring each question’s correct answer is based on specific details from the text. Check for any possible ambiguities but since the difficulty is hard, some questions may require precise details. Each option should be plausible but only one correct. For example, question about alignment steps must follow the procedure from the text. Make sure the wording of choices matches the content.
