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
As hardware engineers, oscilloscopes are our closest allies. But have you ever encountered the following issues: clearly connected signals, yet the waveforms are severely distorted; wanting to capture instantaneous anomalies, but always missing them; analyzing long-duration signals, yet the details remain unclear… These problems are likely due to not fully understanding the three key indicators … Read more
Recently, I acquired a domestic open-source logic analyzer: the PX Logic logic analyzer produced by Octopus.This logic analyzer focuses on high-speed acquisition, with the following performance specifications:• Maximum 32-channel logic analyzer• In buffer mode, supports up to 8 channels at 1G, total bandwidth 8G, storage depth 4Gbits• Under USB3.0 stream mode, supports up to 2 … Read more
The core performance of an oscilloscope is mainly determined by three factors: bandwidth, sampling rate, and storage depth. 1,Bandwidth What is bandwidth? Bandwidth refers to the frequency range over which a system or channel can effectively process and transmit signals. Specifically defined for oscilloscopes: For an oscilloscope, bandwidth typically refers to its -3 dB bandwidth. … Read more
The oscilloscope is the most commonly used tool by hardware engineers, which can be used for basic waveform testing, confirming whether related parameters meet requirements, and for diagnosing circuit anomalies; it can also be used for eye diagram testing of high-speed signals, Ethernet port template testing, jitter analysis, etc.; or for decoding commonly used serial … Read more
Basic Controls on the Front Panel Typically, oscilloscopes are operated using the knobs and buttons on the front panel. In addition to the controls on the front panel, many high-end oscilloscopes are now equipped with an operating system, allowing them to be operated like a computer. You can connect a mouse and keyboard to the … Read more
1. Explanation of Core Concepts DAC (Digital-to-Analog Converter): Its function is to convert digital codes (0s and 1s) into real analog voltage or current signals. It serves as a bridge between the digital world and the analog world. Sampling Rate: Refers to the number of times the DAC can perform this conversion operation per second. … Read more
Before purchasing an oscilloscope, it is essential to understand your product and determine what type of equipment you need based on the objects you intend to test. It’s not necessarily true that the more advanced the equipment, the better the product will be. Previously, some netizens summarized 10 suggestions, which I personally think are quite … Read more
