DIGITAL DEBUG / LOGIC ANALYZERS
Logic Analyzer Procurement Guide
Select logic analyzers by channel count, timing resolution, memory, voltage thresholds, protocol decode, triggering and automation needs so the instrument matches the digital system under test.
Define digital capture needs
- Record the number of signals, logic levels, fastest transitions and maximum event duration that must be captured.
- Separate timing analysis from state or protocol analysis because sampling and memory requirements can differ materially.
- List required protocol decoders and triggering conditions before comparing bundled software features.
Include probes and fixtures
- Treat probe loading, ground strategy and connection density as part of the measurement system.
- Choose adapters and breakout fixtures that allow repeatable access without compromising the circuit or creating fragile temporary wiring.
- Include spare probe accessories and replacement leads in the lab acquisition scope.
Automation and lifecycle
- Check data export, scripting or remote-control functions if the analyzer will be used in regression or production test.
- Store instrument configuration with the test procedure when captures support formal troubleshooting or validation.
- Verify firmware support and host-software compatibility before standardizing the lab fleet.
