A logic analyzer is a dedicated debug tool for digital signals, offering long-time acquisition, no dead time, advanced trigger conditions, and rich protocol decoders. With a USB logic analyzer or high-speed logic analyzer, you can easily capture and analyze complex communication sequences in protocols like I²C, SPI, UART, CAN, and more.
While an oscilloscope is ideal for viewing voltage waveforms, periodic signals, and noise variations, a logic analyzer focuses on recording digital high/low states, making it far better for analyzing digital communication processes, timing relationships, and complex protocols in embedded systems, microcontrollers, and FPGA projects.
A digital signal analyzer can significantly improve efficiency in digital circuit debugging, firmware development, and protocol analysis, saving you time and helping you pinpoint issues quickly.
Why DSLogic ?
1. Continuous Improvement

5 years,1800 days and nights,300 improvements

2. Dual Mode Support
Main spec. of LA:
Sample duration and Sample rate
Buffer mode:Â High sample rate
Stream mode:Â Long sample duration
Why you need a high sample rate?

Sample rate is like screen resolution
The higher the better
Stream mode
Data are transferred to computer in real-time through USB
Greatly increase the sample duration

Sample duration
Buffer mode vs Stream mode

DSLogic vs DSLogic U3Pro
3. Signal Integrity
As a qualified LA, high sample rate is not enough. It is necessary to ensure that high-frequency signals can be transmitted without distortion on the entire path of signal acquisition.
DSLogic ensure the signal integrity with following designs

Metal case + shielded fly wire
