DSLogic is a series of USB-based logic analyzer, with max sample rate up to 1GHz, and max sample depth up to 16G.

DSLogic is protected by a CNC metal case to enhance noise immunity. Combined with shielded fly wires, DSLogic can be used to capture up to 250MHz digital signals (under 1G sample rate).

Have trouble on debugging digital circuits with oscilloscope?
For example: small depth, hard to trig, rough protocol decoders …

Logic analyzer is a dedicate debug tool for digital signals, which support long-time acquisition, no dead time, complex trig conditions and rich protocol decoders.

Oscilloscope is wonderful for analyzing periodic voltage and noise changes; Logic analyzer only record low/high status, and is much better at analyzing process of digital communications and complex protocols.

Software Open source, Hardware Patented & Certified

Multi-platform support
Driver with digital signature

Main spec. of LA:

Sample duration and Sample rate

Buffer mode: High sample rate
Stream mode: Long sample duration

Why you need a high sample rate?

Sample rate is like screen resolution
The higher the better

Under test signal

Results at different sample rates

The higher sample rate the better restored waveform
We recommend the sample rate should be 10x – 100x than frequency of under test signal

Stream mode
Data are transferred to computer in real-time through USB
Greatly increase the sample duration

Sample duration
Buffer mode vs Stream mode

Stream mode problem:
Real-time transmission is limited by USB bandwidth
Only 3 channels support under 100M sample rate

DSLogic U3Pro support super stream mode
Use USB 3.0, bandwidth up to 5Gbps
10 times than normal stream mode

DSLogic vs DSLogic U3Pro

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

Structure of shielded fly wire

High-speed PCB design

Dupont fly wire vs Shielded fly wire
