Lessons
Lesson 1
Survey of Essential Test Equipment
Engineers and technicians rely on oscilloscopes as indispensable tools for testing. These instruments play a crucial role in measuring and analyzing electrical signals. This lesson provides an overview of various types of test equipment, emphasizing the significance of oscilloscopes in the field.
Lesson 2
Scaling Waveforms
Waveforms on oscilloscopes are visual representations that plot the voltage of a signal against time. Accurate depiction of the waveform requires precise adjustment of the oscilloscope's horizontal and vertical scales. This lesson delves into the proper configuration of these scales on the oscilloscope for optimal waveform display.
Lesson 3
Probing Part 1 – Compensating Passive Probes
Electronic circuits are linked to oscilloscopes through probes, which play a crucial role in achieving accurate measurements. Ensuring proper connection and compensation of probes is essential for reliable results. This lesson provides insights into the utilization of passive probes, offering guidance on how to connect and compensate them to enhance accuracy in measurements.
Lesson 4
Triggering Part 1 - What the Heck is Triggering?
Explore the fundamental concept of triggering and learn how to effectively utilize it for capturing specific events on a waveform.
Lesson 5
Cursor Measurements
Utilize oscilloscopes for measuring waveform properties such as amplitude and frequency. This lesson illustrates the application of the oscilloscope's cursors for accurate measurements.
Lesson 6
Automatic Parametric Measurements
Oscilloscopes leverage automatic parametric measurements to swiftly and effortlessly compute key waveform parameters, including amplitude, frequency, and rise time. This streamlined process not only saves engineers time and effort but also aids in promptly identifying issues within their circuits.
Lesson 7
Probing Part 2 - Active Probes
Active probes offer several benefits compared to passive probes, such as increased bandwidth, reduced noise, and enhanced protection for the oscilloscope. Consequently, they are better suited for measuring high-frequency signals and signals with small amplitudes.
Lesson 8
Waveform Math and Power Measurements
Oscilloscopes leverage waveform math to merge two or more waveforms, and power measurements enable the calculation of a waveform's power. This functionality proves valuable for analyzing signal properties like amplitude, frequency, and rise time.
Lesson 9
Frequency-domain Measurements (FFT)
The Fast Fourier Transform (FFT) is employed to transform a waveform from the time domain to the frequency domain. This proves valuable for scrutinizing the frequency spectrum of a signal, assisting engineers in the identification of harmonics and other potential issues.
Lesson 10
Frequency Response Analysis (Bode Plots)
Bode plots serve as a visualization tool for depicting the amplitude and phase response of a system across varying frequencies. This proves beneficial in the analysis of system stability and the identification of resonant frequencies.
Lesson 11
Triggering Part 2 - Auto vs Normal
While automatic triggering offers convenience in waveform capture, it may lack the precision of normal triggering. Normal triggering empowers engineers to pinpoint the exact moment for waveform capture, enhancing accuracy. This capability proves invaluable for troubleshooting, allowing engineers to specify precise points such as capturing a specific pulse by setting the exact time of its occurrence using normal triggering.
Lesson 12
Triggering Part 3 - Trigger Holdoff
Trigger holdoff is a valuable feature that prevents the oscilloscope from triggering multiple times on a repeating waveform. This proves beneficial in troubleshooting issues like jitter. For instance, when troubleshooting a digital circuit experiencing signal jitter, trigger holdoff can be applied to avoid triggering on every pulse. This ensures a clearer observation of the jitter phenomenon.
