The oscilloscope is undoubtedly one of the most important tools in research and development. To clearly observe what a signal looks like, an oscilloscope is essential! Here are some points to consider when selecting one: ① Sampling Rate ② Bandwidth ③ Storage Depth First, let’s talk about the sampling rate. 1: Sampling Rate How do … Read more
Today’s Keywords:Practice and Accumulation When the light trail of the oscilloscope first jumped into a full sine wave in front of Zhang Jingkai, this student from Shandong University, who was “trapped” by the analog electronics formulas, suddenly understood another way of writing “growth” — it is not an instant epiphany, but a persistence of repeated … Read more
Are you interested in DIY electronics but deterred by the high prices of various instruments? I recently got into DIY and was considering purchasing an oscilloscope when I stumbled upon a treasure project—EMBO (EMBedded Oscilloscope). For just six dollars (USD), you can transform an STM32 into an oscilloscope, logic analyzer, voltmeter, counter, PWM/signal generator… it’s … Read more
Different Photography Seeking a Peaceful Time ROMANCE IN THE WORLD Can’t Understand the Oscilloscope? Yesterday we embarked on a color grading journey, but relying solely on the human eye on potentially inaccurate displays is like driving in a fog. Today, we will equip ourselves with a “radar” and “GPS”—that is the oscilloscope. Don’t be intimidated … Read more
