scopes and data logging -凯发k8网页登录

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.
