# Questions for Electronics Engineering Experts: Oscilloscope, Function Gen & DMM

• Tami22
If so, then you need to follow the guidelines of the forums.In summary, the conversation discusses the questions related to Oscilloscope, function generator, and Digital Multimeter, particularly the DC offset on the function generator, the frequency range and type of signals available, the difference between readings at AC and DC settings on the Digital Multimeter, and the difference between measurements under DC and AC coupling. The speaker is a student of electronics engineering and is seeking help from experts in the forum. They are also asked about their prior research on the topic and if this is for a schoolwork question.

Hi experts,
I am a student of electronics engineering and a new member. I have few questions related to Oscilloscope, function generator and Digital Multimeter.
1. what does the DC offset on the function generator do?
2. What is the frequency range and type of signals available?
3. What is the difference between the readings at AC and DC settings on the Digital Multimeter?
4. Is there a difference between the measurements under DC and AC coupling and Why?

Welcome to PhysicsForums.

And is this for a schoolwork question?

## 1. What is an oscilloscope and how does it work?

An oscilloscope is a piece of electronic test equipment used to measure and display electrical signals. It works by taking in a voltage signal and displaying it as a graph on a screen, with time being represented on the horizontal axis and voltage on the vertical axis. This allows for the visualization and analysis of the signal's characteristics, such as amplitude, frequency, and waveform shape.

## 2. What is a function generator and what are its uses?

A function generator is a device that produces various types of electrical waveforms, such as sine, square, and triangle waves. It is commonly used in electronics engineering for testing and troubleshooting circuits, as well as in research and development for creating specific waveforms for experiments. Function generators can also be used in educational settings to demonstrate different types of waveforms and their properties.

## 3. What is a digital multimeter (DMM) and how is it used?

A digital multimeter is a versatile tool used to measure various electrical quantities, such as voltage, current, and resistance. It works by using probes to make contact with the circuit being tested and then displaying the measured value on a digital screen. DMMs are commonly used in electronics engineering for circuit testing, troubleshooting, and calibration.

## 4. Can an oscilloscope, function generator, and DMM be used together?

Yes, these three pieces of equipment are often used together in electronics engineering. The oscilloscope can be used to visualize the output of the function generator, while the DMM can be used to measure the voltage, current, or resistance of the circuit being tested. This allows for a more comprehensive analysis and understanding of the circuit's behavior.

## 5. What are some important factors to consider when choosing an oscilloscope, function generator, or DMM?

Some important factors to consider when choosing these pieces of equipment include the frequency range, accuracy, and resolution of the measurements, as well as the number of channels and sampling rate. It is also important to consider the specific features and capabilities that are needed for the intended use, as well as the cost and reliability of the equipment.
