When testing a RAT (radio alarm transmitter), which type of fault must be caused between elements of the transmitting equipment?

• A. A short circuit
• B. An open circuit
• C. A fault
• D. A ripple

Answer: (C)

When testing a RAT, you deliberately induce a fault between parts of the transmitter to verify that the unit detects and signals fault conditions correctly. The important idea is testing the system’s response to an internal abnormal condition, not one specific fault type. A short circuit or an open circuit are examples of faults, but the requirement is to create a fault in general so the fault-detection path can be exercised. A ripple isn’t a fault type used for this purpose. So the focus is on provoking a fault between elements of the transmitting equipment.
