Type: cac

Configuration

• name: (str) name of node.
• interval: (int) strip interval. Default is 1.
• enabled: (bool) enabled state. Default is true.
• parameters:
  • hv_channels: (list) list of high voltage channels. Default is [].
  • lv_channels: (list) list of low voltage channels. Default is [].
  • lcr_amplitude: (metric) LCR amplitude in Volt. Default is 1 V.
