1.A. What is the primary advantage of measuring a voltage with an oscilloscope verses using a digital multimeter? = B. Explain how both the amplitude and the frequency of a repetitive signal can be determined using an oscilloscope. - C. If the oscilloscope displays a sine wave that is 6 divisions high and each division is 0.2V, what voltage do you expect to read on your multimeter if it is set to ac volts? D. Explain how to adjust an oscilloscope so that the displayed tracing of a repetitive signal is steady, and doesn't drift across the screen.
