Control logic analyzer Nets through the Lager CLI for digital signal capture, protocol decoding, and trigger configuration.
Not Yet Available: The Logic Analyzer feature for Rigol MSO5000 series is currently under development. The commands below are documented for preview purposes only. The underlying device methods are not yet implemented and the CLI command is disabled. Attempting to use these commands will result in an error. Check back in a future release for full functionality.

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
