In the last tutorial on CRO I gave you a detailed idea about the various components of an Oscilloscope concerned with the positioning and magnification of an input signal and the role of probes was also explained. Now since you have been acquainted with the primary knobs of a Cathode Ray Oscilloscope it’s time to dive deeper and to know more about the other knobs which are helpful in further observation of a signal. Interestingly, CRO comes with numerous options regarding input functions and all the functions are quite distinctive in their approach. This article would detail with all the basic functions and special functions that a standard CRO device has. Moreover, there is also an interesting example of how these functions participate to make a CRO complete a given task. So, keep on reading to discover another chapter of this interesting measuring and analytical gadget.
In the tutorial/lesson we are going to learn about the practical details which are necessary for a layman to use one of the very important device in electronics known as Cathode-Ray Oscilloscope abbreviated as CRO or just Oscilloscope or earlier known as Oscillograph. At the completion of this tutorial we will be able to operate the CRO as per our requirement in different activities or experiments. What is a CRO and what is it used for? An Oscilloscope is an electronic device generally used to obtain the wave-form of different signals applied to it. Unlike a MultiMeter which is also used for the measurement of the values of different signals or resistances or any other electrical parameter, which depicts the instantaneous values of an electrical parameter, an Oscilloscope on the other hand expands the time window for the observer to have a better picture regarding the properties of the signal applied to it.
