Technician A says the output of a Hall-effect sensor can be checked with an AC voltmeter. Technician B says output of a magnetic pulse generator can be tested with a lab scope. Who is correct?
A) Technician A only
B) Technician B only
C) Both Technician A and B
D) Neither Technician A nor B

Technician B is correct because the output of a magnetic pulse generator (often used in vehicle speed sensors, crankshaft position sensors, etc.) can indeed be tested with a lab scope, which allows for the visualization of the waveform generated by the sensor. Technician A is incorrect because a Hall-effect sensor typically produces a digital (on/off) signal, not an AC signal, so an AC voltmeter would not be the appropriate tool for testing its output.
