An oscilloscope how to use is a very powerful tool that can measure currents, voltages, and other waveform characteristics. It can show how a signal changes over time, and it can help you debug circuits and get them to work properly. It can also decode complex communications signals like RS232 and I2C.
Understanding how to use an oscilloscope starts with knowing the basics of what it can do. The front panel of an oscilloscope contains a set of controls that control the operation of the instrument. These are typically grouped into sections. The first section usually controls triggering, and the other sections are used to specify what type of waveform you want to display.
Getting Started: A Beginner’s Guide to Using an Oscilloscope
The most basic thing that an oscilloscope can do is to measure the difference in voltage (amplitude) between two points. This is commonly referred to as peak-to-peak, but there are other measurements that an oscilloscope can do. Examples include measuring the minimum and maximum values of a signal, the mean or average value of a signal, and other mathematical calculations such as delay and runt triggering.
To make the most accurate measurements you need to have a probe that is compensated for its input impedance. Every probe has a small amount of resistance and capacitance added to its input. This effect is more noticeable for higher frequencies, and the probe may need to be adjusted to correct for it. Most probes have a screw-head on the tip or near the base where it connects to the oscilloscope. You can adjust the compensation using this screw-head, and you will need a flathead screwdriver to do so.Read More →
