Project 2: Oscilloscope

The Arbitrary waveform generator instrument will be used to apply relatively rapidly varying wave forms to the oscilloscope, and then triggering of the waveform will be used to make the waveform easier to view and analyze.

Math Channels

Project 4: Oscilloscope

Introduces the use of the math channel function on the Analog Discovery. This function allows the user to perform a wide variety of mathematical operations, all of which can be applied to the voltages being measured.

Oscilloscope Triggering

Oscilloscope triggering allows us to assign a “zero time” to a particular feature on the signal. That feature gets placed on the same point on the plot window every time the oscilloscope screen updates; if the signal repeats itself based on this feature, the oscilloscope will display the same section of the signal every time the screen updates, making the signal appear to be unchanging.

Data Display Using Oscilloscopes


The fundamental purpose of an oscilloscope is to measure and display voltages as a function of time. A plot of the voltages vs. time is provided in the main waveform window of the oscilloscope. The horizontal axis of the waveform window is time, and the vertical axis is voltage. The user can control the waveform display by adjusting these axes.

Continuous and Single Sequence Acquisition


Oscilloscopes typically provide multiple approaches to acquiring and displaying data. The two most common and most distinct approaches are continuous acquisition and single-sequence acquisition. This topic page explains each approach.
