Control logic analyzer Nets through the Lager CLI for digital signal capture, protocol decoding, and trigger configuration.
Coming Soon: The Logic Analyzer feature for Rigol MSO5000 series is currently under development.
The API is documented for preview purposes, but the underlying device methods (is_la_enabled, enable_la, etc.)
are not yet implemented. 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
