The resistance between the input terminals of an oscilloscope are very large. Does that make it more like a voltmeter or more like an ammeter? Why? Do you make measurements in parallel or in series with the circuit elements?
The Oscilloscope has two display axes. What quantities are
typically displayed on the two axes in sweep mode? What about in XY
mode?
Describe how to measure the amplitude of a sine wave signal in sweep mode. How does that differ from the peak-to-peak and RMS voltages?
Describe how to measure the frequency of a sine wave signal in sweep mode.
What is meant by triggering?
The resistance between input terminals of an oscilloscope are very large it means oscilloscope can be used as a voltmeter not as a ammeter.
For this it should be connected in parallel, so that current should not be affected in the circuit due to very large resistance.
The oscilloscope has two display axis, on horizontal or x- axis time is displayed and on vertical or y-axis voltage is displayed.
Amplitude of sine wave is measured from reference or base line to the peak of the sine wave.
Peak voltage or amplitude are equal but RMS voltage is equal to (1/√2) times of peak voltage.
To measure frequency we should measure time period or time to complete one cycle, from x-axis. Then the reciprocal of period will give frequency.
Triggering means to achieve clear signal charactrization by synchronization of horizontal sweep.
