Flex Technician Interview Questions and Answers

A CRO (Cathode Ray Oscilloscope) is used to display and analyze waveforms, while a function generator is used to generate different types of waveforms.

• CRO is used for visualizing electrical signals in the time domain, while a function generator is used to create specific waveforms like sine, square, triangle, etc.

• CRO provides a visual representation of the input signal's amplitude, frequency, and phase, while a function generator allows users to control the frequency, amplitu...read more
