[009] DSLogic Logic Analyzer Review and Teardown
Why people recommend it
OpenTechLab's in-depth DSLogic teardown and review is suggested to anyone comparing logic analysers, though one commenter questioned part of its input circuit explanation.
Watch for: Some debate over its analysis of the input stage
In their words
The DS logic input is simply a 7kΩ resistor in series before the FPGA input (there is also a few zeners for input protection).
