Measurements and Cursors
Project 3: Oscilloscope
Introduction
In our first two oscilloscope projects, we examined the way to display a waveform on our oscilloscope so that we can visualize the “shape” of a voltage with respect to time. We can measure parameters that we may be interested in—amplitudes, frequencies, phase differences, and so on—directly from this display, since vertical and horizontal scales are provided on the display; however, most oscilloscopes provide tools which assist in the measurement process. This project will familiarize us with some of the most basic and common tools used to simplify the measurement process.
Please be aware that these tools are not a substitute for scrutinizing the waveform display itself! Measurement tools are intended to be used in conjunction with engineering insight into the circuit's behavior. When an oscilloscope displays a “measurement”, the tool may be making assumptions about the waveform which are not valid! Always perform at least a rough double-check of any displayed measurements against the waveform itself.
The tools introduced in this project are the measurements tool and the cursors. The measurements tool provides automated measurement of a number of common parameters. The cursors are generally used if a specific voltage or time measurement is desired, which needs to be customized by the user.
Before you begin, you should:
- Complete the second oscilloscope project relative to Triggering.
After you're done, you should:
- Use the Analog Discovery™ oscilloscope measurement and cursor functions to display signal parameters.
Procedures
Shortcut!
If you have completed the Oscilloscope Triggering project, and your circuit is still intact, you will be ready to begin this exercise. If you no longer have the circuit set up, check out and construct the circuit displayed to the right.
Step 1: Create a Measurement
- First, we will measure the maximum value of the channel 1 voltage displayed on the screen, as shown below.
The measured value should appear in the list in the Measurements window. Check the value against the waveform shown in the display screen, to see if it makes sense. You can add additional measurements using the Add Measurement dialog box now. When you are done, close the Add Measurement dialog box.
- You can add more measurements to, or remove existing measurements from,
the Measurements window by clicking on the
or 
buttons. Try it!
Step 2: Using Cursors
- We will use cursors to measure the maximum value on channel 1 and the
duration of the flat “plateau” of the channel 2 waveform.
- In general, to set up a cursor, click and drag the
and
icons located near the
lower-left and upper-right corners of the display window. Two
“x” and two “y” cursors are available. - Steps to set up cursors for the specific measurements we want to make are shown in the figure below.
- In general, to set up a cursor, click and drag the
Test Your Knowledge!
Use the Measurement window to measure the maximum channel 2 voltage that you used cursors to measure in part B. Does the value in the Measurement window agree with the results you obtained with the cursor?
- Use both the Measurement window and the cursors to calculate what you would think of as a “rise time” for channel 2. (Generally, “rise time” indicates the time required to get from one voltage level to another. It is usually measured as the time necessary to get from 10% to 90% of the difference between the two voltage levels.) Do the results make sense relative to one another?
