In this section we review the key terms and specifications, what they mean and why they are important to you. We also review the key instrument controls and how they operate.

You can download an Introduction to Oscilloscopes Laboratory Guide developed by one of our educational customers for detailed curriculum on all of these topics

What does Bandwidth Mean?

A basic concept in determining what scope you need is understanding the key performance characteristic of an Oscilloscope - Bandwidth. Selecting proper Bandwidth ensures reliable and accurate measurements.

Sample Rate Vs Memory Depth

A digital scope's ability to make long captures is directly tied to the relationship between the instruments sample rate and memory depth. Explore how the two factors interact and the impact on your measurements.

Horizontal System and Controls

Horizontal controls allow for positioning the signal on the time X axis as well as adjust the time based scaling options.

Vertical System and Controls

Vertical controls allow for the adjustment of amplitude scaling settings, bandwidth limits and and probe attenuation as well as positioning positioning the signal on the vertical axis.

Making Your First Measurement

Provides and overview on how to quickly and easily start making measurements on your oscilloscope.

In order to clearly display and analyze a signal the instrument needs a consistent start point for data capture. This is called triggering and it is controlled by an instrument's trigger system.

Triggering concepts and curriculum are also covered in our introductory lab guide.

Introduction to Triggering

Overview of what triggering is, why it is important, and some key terminology associated with it.

Using Edge Trigger

Edge triggering uses the rising or falling edge of a signal to trigger the oscilloscope.

Using Pulse Trigger

Pulse triggering uses the width of a pulse to determine when to trigger the oscilloscope.

Using Delay Trigger

Delay triggering is used to trigger when time differences between signal transitions either fail to meet minimum thresholds or exceed maximum thresholds.

Using Nth Edge Trigger

Nth Edge Trigger is used to trigger after a defined number of pulses have passed helping trigger on and debug complex serial patterns

Using Setup and Hold Trigger

Setup and Hold trigger is used to verify the minimum amount of time that data is stable after a clock transition.

Using Runt Trigger

Runt triggering is used to trigger the oscilloscope when a runt pulse fails to pass both the low and high trigger points.

Using Serial Bus Triggering

Serial triggering is used to trigger the oscilloscope based on specific behavior, command, or data set found on the serial bus

Using Pattern Triggering

Pattern triggering is used to trigger the oscilloscope when multiple signal conditions are met in a digital system.

Using Duration Triggering

Similar to pattern triggering, duration triggering is used to trigger the oscilloscope when multiple signal conditions are met based on how long the desired state persists

Using Slope Triggering

Slope triggering is used to trigger the oscilloscope based on the rise or fall time of a signal

To accurately measure your systems behavior requires an understanding of factors impacting your acquisition system like loading, noise, and instrument setup.

Advanced Concepts like Signal Integrity, Math, and Advanced Analysis are covered in our advanced lab guide and curriculum.

Probing Basics

Making connection to your device under test is critical to accurate measurements. Learn the basics parts of the probing system and what they do.

Probe Compensation

In order to insure system signal fidelity it is critical that probes be compensated to the instrument. Over or under compensated probes can cause distortions of your measurements and bad results.

Signal Acquisition Techniques

Provide an explanation three main data acusition techniques: Auto Triggering, Normal Triggering, and Single Shot Triggering and explore why you would use each.

High Impedance vs. 50 Ohm Impedance

Explains why 50 Ohm impedance inputs can improve signal fidelity on high speed signals by removing reflections caused by capacitance or inductance

AC/DC Coupling

AC Coupling removes the DC portion of a signal making it easier to analyze waveforms that have a large DC offset

The modern digital oscilloscope can perform many specific analysis tasks that allow the user to get to an answer quickly and easily.

Advanced Concepts like Math, FFT, and other advanced Advanced Analysis topics are covered in our advanced lab guide and curriculum.

Using Standard Measurements

The Oscilloscope comes with many standard measurements to help you quickly get to the root cause of your design problems.

Using Math Operations

Math functions allow you to perform calculations on one or more signals allowing for rapid signal comparison and enabling advanced modeling of more complex waveforms.

Using FFT Analysis

FFT (Fast Fourier Transform) enables you to visualize and analyze time based data in the frequency domain.

Using Record Mode

A simplified method for capturing, searching and analyzing waveforms over time.

Using Pass/Fail Analysis

Using a easily defined mask the oscilloscope can perform pass fail tests to quickly identify out of bounds conditions on a system under test.

Using Digital Filtering

Digital Filtering allows users to separate harmonics from complex compound signals and attenuate the power in certain frequency bands

Using Serial Decode

Serial Decode allows the user to view serial bus traffic in a human readable format.

Using Cursors

Use Cursors to make measurements between specific points on a captured waveform.

Using Phase and Delay Measurements

Quickly determine the delay and phase between multiple channels using standard delay and phase measurements helps to identify system interactions and timing problems

Using High Waveform Capture rate to find an infrequent annomoly

High waveform capture rate limits the "dead time" between aqusitions and increases your probability of caturing infrequent events

Using Deep memory to speed debug of your design

See how long record length can allow for longer higher resolution captures speeding time it takes to find ellusive problems.

Saving, moving and sharing data is an important part of the design process. The modern digital oscilloscope gives you amazing tools to save time
