Yokogawa UART + I2C + SPI trigger and analysis
The Yokogawa 709821-F01 is an optional software feature for the DL9000, DLM2000, and DLM4000 series digital oscilloscopes. This option enables advanced trigger and analysis capabilities for UART (RS232/422/485), I2C, and SPI serial buses. With this option installed, users can trigger on specific protocol-level events, decode serial data in real time, and display protocol information directly on the oscilloscope screen. The feature supports a wide range of baud rates and protocol configurations, providing engineers with powerful tools for debugging and validating embedded systems that use these common serial interfaces. The option is activated via a software license key.
