Key Features
50–200 MHz USB 3.0 Oscilloscope Family
Choose 2-channel or 4-channel models across 50, 70, 100 and 200 MHz bandwidth classes, with portable USB 3.0 connectivity for laptop-based laboratory and field use.
Deep Memory Up to 512 MS
The larger models capture long serial-bus sessions, intermittent events and extended timing windows without forcing an immediate reduction in sample rate.
MSO Models Add 16 Digital Channels
MSO variants combine analog channels with a 16-channel logic analyzer, enabling time-correlated analog and digital debugging on embedded boards.
Serial Decode and Mask Testing
PicoScope workflows support protocol decode, event tables, mask tests, actions, math channels and FFT spectrum views for debug and validation tasks.
Built-in Function / Arbitrary Generator
All 3000D units include a function generator and 12-bit AWG for stimulus, sweep testing, filter response checks and triggered waveform output.
SDK and Automation Friendly
PicoSDK support enables custom test automation and data capture workflows using common programming environments and test-system integration.

Applications
Analog + Digital Protocol Debug
Use MSO models to view power, clock, analog sensor and 16-channel logic activity with serial protocol decode in one time-correlated capture.
University PC Oscilloscope Labs
Portable USB 3.0 instruments support electronics, embedded systems and signal-analysis labs without large bench-scope infrastructure.
Laptop-based Diagnosis
Small size, USB connectivity and deep memory make the 3000 Series practical for site troubleshooting, service and repair work.
SDK-driven Functional Test
Use PicoSDK to automate capture, measurement, data export and pass/fail checks in compact production or incoming-inspection stations.
Control-loop and Filter Testing
Combine AWG sweep workflows with FFT and measurements for amplifier, filter, power-supply ripple and control-loop checks.
Long-record Data Capture
512 MS memory, segmented capture and export workflows help capture rare events and long-duration experimental signals.
