A logic probe is used to

• A. Shows activity at a point in the circuit
• B. Stores data
• C. Generates timing signals
• D. Powers the circuit

Answer: (C)

A logic probe is used to show activity at a point in the circuit by displaying the current logic level of that node. It quickly reveals whether the signal is high, low, or pulsing, helping you see stability or transitions and spot timing issues or faults at that node. It doesn’t store data, since it doesn’t remember or archive values. It doesn’t generate timing signals, which would require a timing source like a clock or signal generator. And it doesn’t power the circuit; power comes from the circuit’s own supply.
