Electromagnetic nuisance coupling mode - conducted and radiated nuisance

The coupling mechanism of electromagnetic harassment is usually categorized into two main types: propagation by conducted harassment and propagation by radiated harassment. Electromagnetic harassment propagated through conductors is called conducted harassment; electromagnetic harassment propagated through space is called radiated harassment. Here's how to learn about conducted nuisance...

Understanding Time Domain Signals - Frequency Domain Signals - Modulation Domain Signals in One Article

Time-domain signals record the waveform information of the signal, which can be tested with an oscilloscope; frequency-domain signals record the frequency distribution information of the signal, which can be tested with a spectrometer; modulated signals are divided into analog, digital, noise, and distortion modulated signals.

RS232 serial communication how to use DB9 connector

RS232 is also called serial communication, commonly used in electromagnetic compatibility test equipment communication interface, when we encounter the use of RS232 serial communication equipment, the following to understand how to correctly configure the DB9 connector pin as well as how to tester with ...

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.
