Tip：Click the above↑ to quickly follow this account For a long time, the logic analyzer has been shrouded in mystery. While most R&D personnel are very familiar with oscilloscopes, they may still be somewhat unfamiliar with logic analyzers. You might guess that it is an expensive, large instrument with a bulky chassis. Right or wrong, … Read more
Click the blue text above to follow us The logic analyzer is an instrument that collects and displays digital signals from the test device using a clock, primarily for timing judgment. Unlike oscilloscopes, which have multiple voltage levels, logic analyzers typically display only two voltages (logic 1 and 0). After setting a reference voltage, the … Read more

In a previous article, we introduced a logic analyzer built using a serial port. Today, we will discuss a logic analyzer based on USB2.0+FPGA. Before we begin, let’s introduce a logic analyzer’s host software – sigrok. Without good host software, even if the hardware is built, the experience will not be good. sigrok Here is … Read more
This series will bring systematic learning of FPGA, starting from the most basic digital circuit fundamentals, with the most detailed operational steps and straightforward language descriptions, providing a “foolproof” explanation. This allows students majoring in electronics, information, and communication, as well as newcomers to the workplace and professional developers looking to advance, to have a … Read more
0x01 Introduction Recently, I purchased a logic analyzer. I had limited exposure to digital signals and inter-chip communication before, but I have been studying these topics intensively over the past few days and now I would like to document my findings for future reference. 0x02 What is a Logic Analyzer Introduction to Logic Analyzers A … Read more
Abstract There are numerous articles introducing the performance of logic analyzers, but few specifically discuss the measurement probes for logic analyzers. It is important to note that the instrument itself is only part of the measurement system; the choice of measurement probes and their manufacturing processes are also crucial. Many times, we use the most … Read more
Overview A logic analyzer is an instrument used to analyze the logical relationships in digital systems. It belongs to the category of data domain testing instruments and is a type of bus analyzer, meaning it is based on the concept of buses (multiple lines) and can observe and test data flows across multiple data lines. … Read more
Build a 100MHz Logic Analyzer with Raspberry Pi Pico Transform a Raspberry Pi Pico (or any RP2040 board) into a simple logic analyzer in 5 minutes. Introduction A logic analyzer is an electronic instrument that captures and displays multiple signals from digital systems or circuits. It can convert captured data into timing diagrams, protocol decoding, … Read more
The logic analyzer has always been shrouded in mystery. While most R&D personnel are very familiar with oscilloscopes, they may still be somewhat unfamiliar with logic analyzers. Perhaps you guessed it is an expensive, large instrument with a bulky chassis. Whether right or wrong, at least that’s what I thought when I was in college. … Read more
