Supported Hardware

Manufacturer	Model Series	Features
Rigol	MSO5000	Mixed-signal, protocol decode

Notes

Logic nets capture digital signals (high/low states)
Protocol triggers (I2C, UART, SPI) require proper level configuration
Use lager nets to see available logic nets
Analog and Logic nets can be combined for mixed-signal analysis
