What kind of oscilloscope do you need to test sensors?
Most design and test engineers own a digital storage oscilloscope ( DSO ). This paper will endeavor to give good advice on methods to apply the power of DSO’s to the types of signals typically produced/detected by sensors and actors starting with simpler examples and moving toward more complex ones.
How to reset the oscilloscope to the default state?
The following steps will reset the oscilloscope to the default state: Hit the “Save/Recall” button Select “Recall Factory Setup” from the items at the bottom of the screen Select “OK Confirm Factory Init” from the items at the right of the screen Hit the “Menu Off” button
How does the sampling rate of an oscilloscope work?
The sampling rate of an oscilloscope reflects how often the analog to digital convertor (ADC) measures the size of the signal. In order to get a good view of the signal shape, you want the scope to provide many sample points which “draw” a connect-the-dots picture of the signal amplitude vs time.
How many channels can an oscilloscope read at a time?
Channel Amount — Many scopes can read more than one signal at a time, displaying them all on the screen simultaneously. Each signal read by a scope is fed into a separate channel. Two to four channel scopes are very common. Sampling Rate — This characteristic is unique to digital scopes, it defines how many times per second a signal is read.
What can an oscilloscope do for an oxygen sensor?
An oscilloscope is real time graphing voltmeter that can monitor the activity of an oxygen sensor or, if equipped with a hold feature, to capture a time and voltage sequence. What will the oscilloscope tell you about the operation of the sensor? It will supply voltage and a time trace according to the set up of the scope.
What should I Set my oscilloscope to display?
Set the oscilloscope to display channel 1. Set the vertical volts/division scale and position controls to mid–range positions. Turn off the variable volts/division. Turn off all magnification settings. Set the channel 1 input coupling to DC.

How does an oscilloscope measure a voltage wave?
An oscilloscope measures voltage waves. A waveform is a graphic representation of a wave. Physical phenomena such as vibrations, temperature, or electrical phenomena such as current or power can be converted to a voltage by a sensor. One cycle of a wave is the portion of the wave that repeats.
