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).
What’s Logic Analyzer ?
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.
Why DSLogic ?
1. Continuous Improvement
5 years，1800 days and nights，300 improvements
Software Open source, Hardware Patented & Certified
Windows
macOS
Linux
Multi-platform support
Driver with digital signature
2. Dual Mode Support
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
2x sample rate
Wrong waveform
pulse loss
5x sample rate
1/5T deviation
error on duty
10x sample rate
1/10T deviation
Good result
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
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
Structure of shielded fly wire
DSLogic 4 layers pcb
DSLogic U3Pro 8 layers pcb
High-speed PCB design
Dupont fly wire vs Shielded fly wire
