Oscilloscope Selection Methods-Part IV

Oscilloscope selection should focus on bandwidth, accuracy, and rise time parameters, which are critical for accurately displaying the actual waveform of the signal under test.

Oscilloscope Triggering and Signal Storage-Part 3

Oscilloscope triggering and signal storage according to the different types of oscilloscopes have a variety of ways to fully understand the trigger coupling, trigger isolation, record length and waveform storage methods, as well as digital oscilloscopes such as pulse width triggering and short pulse triggering.

Principles and Use of Oscilloscopes-Part II

Oscilloscopes mainly rely on sampling the signal under test to be displayed on the screen, so understanding the sampling technology of oscilloscopes can understand the principles and methods of oscilloscopes. From the sampling process to understand the difference between digital real-time sampling and digital equivalent sampling.
