5.2 Pencetusan

The trigger system stabilizes repetitive waveforms and captures single-shot events. Use the Trigger Level knob to set the trigger point. Various trigger modes (Edge, Pulse, Video, Slope, etc.) are available via the 'Trigger' menu.

5.3 Penyahkodan Bas Bersiri

The DS1202Z-E supports decoding of common serial protocols. Access the 'Decode' menu to select the protocol (RS232/UART, I2C, SPI) and configure parameters. The decoded data will be displayed on the screen, simplifying debugging of serial communications.
