The automotive generator is the main power source of a vehicle, functioning to supply power to all electrical devices (excluding the starter) while charging the battery during normal engine operation. The purpose of testing the current and voltage of the automotive generator is to assess the charging rate of the generator, which is related to … Read more
1. Why is it necessary to measure program execution time? Rather than measuring program execution time, it might be more accurate to refer to it as measuring task execution time. The projects we undertake are aimed at achieving specific objectives, thus completing corresponding tasks. Simple projects typically focus on a single task, while more complex … Read more
Recently, I have seen many popular articles using 50-ohm coaxial cables to measure power supply ripple, various styles, and impressive content. I finally took the time to research related articles and would like to share some personal recommendations for measuring ripple & noise with an oscilloscope in my work.When testing power supply waveforms, we often … Read more
Introduction Today, we will evaluate the high-precision timers in the Linux kernel, while also conducting cross-testing using a Tektronix oscilloscope and a DS100 Mini digital oscilloscope. Due to project requirements for precise timing cycles, we need to assess its feasibility and verify whether the oscilloscope from Atomic Clock can support the embedded development process. Overview … Read more
Article Overview There are three view modes for observing waveforms on an oscilloscope: YT mode, rolling mode, and XY mode. While YT mode is sufficient in most cases, how should rolling mode and XY mode be used? What are the advantages and disadvantages of each mode? Oscilloscopes can observe waveforms through various view modes, including … Read more
The oscilloscope is the most common instrument for electronic engineers, and many people liken it to the “eyes” of an engineer, which sufficiently illustrates how important oscilloscopes are to engineers. How is the signal displayed on the oscilloscope screen? On the oscilloscope, the signal transmission goes through a series of resistors and capacitors inside the … Read more
As one of the most commonly used measuring instruments in the electronics industry, oscilloscopes involve a lot of image import/export, data processing, automation operations, and more. Here, we plan to explain in detail the remote control of oscilloscopes, with the following arrangements: 1 Remote image access and control via wireless network (suitable for special occasions … Read more
1. Self-Diagnosis of LIN BusWhen performing self-diagnosis on the LIN data bus system, the address code of the LIN master control module must be used. The self-diagnostic data is transmitted from the LIN slave control module to the LIN master control module via the LIN bus. All self-diagnostic functions can be completed on the LIN … Read more
Application of Real-Time Oscilloscopes in New Generation Optical Interface Time Domain Testing Introduction: When it comes to time domain testing of optical interface metrics, engineers often mention the sampling oscilloscope. This is because sampling oscilloscopes have unparalleled advantages in signal integrity: high bandwidth, low noise, and minimal quantization error (high vertical resolution). However, the downside … Read more
When talking about oscilloscopes, one cannot help but recall the time spent testing at Samsung.The first version of the product’s PCB was followed by time spent in the lab, racing against product cycles, with continuous validation and testing during that period.It has been a long time since I last tested; I feel a bit nostalgic … Read more
