The MAU-169 CCG includes a detector, a computer, and a control section. Which component is NOT part of the CCG?

• A. Power supply
• B. Interface module
• C. Data logger
• D. Inertial measurement unit

Answer: (D)

The key idea is understanding what subsystems are typically included in the MAU-169 CCG to support sensing, processing, and control. Since the CCG already has a detector to collect signals, a computer to process them, and a control section to manage operations, the missing piece should be something that supports power, interfacing, or data storage rather than motion sensing. A power supply is essential to run the whole unit, an interface module bridges the detector and computer to translate signals, and a data logger preserves measurements for later review. An inertial measurement unit, which tracks motion and orientation, isn’t part of this CCG’s core function, so it isn’t included.
