OBJECTIVE: To learn how to operate a cathode-ray oscilloscope.
APPARATUS: Cathode-ray oscilloscope, multimeter, and oscillator.
INTRODUCTION: The cathode-ray oscilloscope (CRO) is a common laboratory instrument that provides accurate time and aplitude measurements of voltage signals over a wide range of frequencies. Its reliability, stability, and ease of operation make it suitable as a general purpose laboratory instrument. The heart of the CRO is a cathode-ray tube
