How can I learn oscilloscope?

Oscilloscope Instructions

1. Set the oscilloscope to display channel 1.
2. Set the vertical volts/division scale and position controls to mid–range positions.
3. Turn off the variable volts/division.
4. Turn off all magnification settings.
5. Set the channel 1 input coupling to DC.
6. Set the trigger mode to auto.

Does oscilloscope need ground?

Grounding the oscilloscope is necessary for safety. The oscilloscope needs to share the same ground as any circuits you are testing. Some oscilloscopes do not require separate connection to earth ground. These oscilloscopes have insulated cases and controls, which keeps any possible shock hazard away from the user.

What can an oscilloscope detect?

The primary function of an oscilloscope is to measure voltage waves. Those waves are displayed on a graph that can tell you many things about a signal, such as: The time and voltage values of a signal. The frequency of an oscillating signal.

How do you calculate PWM voltage?

To determine the proportional PWM output voltage, use this formula: (Duty ÷ 256) x 5 V. For example, if Duty is 100, (100 ÷ 256) x 5 V = 1.953 V; PWM outputs a train of pulses whose average voltage is 1.953 V.

How is PWM current measured?

PWM duty can be measured by reading the voltage (DC average). If you have a “true-RMS” meter you can measure the RMS current directly. If you have an averaging meter, your meter will measure (not surprisingly) the average current, which is a real measurement but does not accurately represent the heating effect.

What are the basics of O-scopes?

Basics of O-Scopes. The main purpose of an oscilloscope is to graph an electrical signal as it varies over time. Most scopes produce a two-dimensional graph with time on the x-axis and voltage on the y-axis.

What can you do with an oscilloscope?

Being able to see a capacitor charging, or how a PWM signal’s duty cycle changes, can be a powerful tool in your learning journey. Beyond learning, an oscilloscope is a very useful tool when you work to verify, maintain and troubleshoot electronic devices.

How do you calculate the rise time of a scope?

The rise time of a scope is very closely related to the bandwidth. It can be calculated as Rise Time = 0.35 / Bandwidth. Maximum Input Voltage — Every piece of electronics has its limits when it comes to high voltage. Scopes should all be rated with a maximum input voltage.

What does an oscilloscope display look like?

Most scopes produce a two-dimensional graph with time on the x-axis and voltage on the y-axis. An example of an oscilloscope display. A signal (the yellow sine wave in this case) is graphed on a horizontal time axis and a vertical voltage axis.
