How to Use an Oscilloscope

A bmw scan software  like taking a pencil in your hand and holding it at the zero point on a graph paper, an oscilloscope allows you to visually track an electrical signal’s change over time. This can reveal a variety of properties about the signal including amplitude, frequency, rise and fall times, distortion, etc. There are an infinite number of signals and an equally infinite number of ways to operate an oscilloscope, but there are some basic steps that you will need to perform every time you use one.

Mastering Oscilloscope Usage: A How-To Guide

First, you will need to connect your signal to the probe that is provided with your scope. You will then need to make sure that the probe’s attenuation setting matches the scope’s (e.g. 1X or 10X). Most probes have a recessed screw head, which you can rotate to adjust the shunt capacitance of the probe, to compensate for its effect on the signal (we’ll explain this in more detail below).

Once your probe is connected to your signal and the scope is turned on, you should see a noisy flat line on the display screen. This is your signal as it changes over time, represented on the vertical axis by squares on the scope’s display (called divisions). You can set the vertical sensitivity and horizontal position on the scope to adjust how much detail you want to see on the screen.

Once you have the vertical and horizontal sensitivity adjusted to your liking, the next step is to turn on your trigger section (usually a button on the front panel). The trigger controls how the scope responds to an input waveform. It will blank the display and stop the sweep circuit if it detects that a voltage level (which you set using the trigger control) has reached a user-specified threshold. After a brief period of time called holdoff (which is usually adjustable with another front-panel control on the scope), the sweep circuit will start again.
