define_relay_channel()

DAQDriverBase.define_relay_channel(

physical_channel: str,

alias: str | None = None,

) → RelayChannel

Build a RelayChannel for physical_channel (e.g. "3101" = slot 3 / channel 101).

Default implementation suits the Keysight 34980A’s slot/channel addressing; override if the driver needs different parsing. Overrides must also record the resulting channel on self._relay_channels.
