Scopes and Data Logging

Display and record data

DSP Scopes visualize your streaming/real-time data using hardware-inspired interfaces. Use measurements, cursors, triggers, and masks to visually inspect and analyze streaming data. In MATLAB®, you can visualize streaming data using scope System objects. In Simulink®, you can visualize signals using scope blocks or apps, or you can save data to MATLAB with the Time Scope or To Workspace blocks.
