IOChannel#
The IOChannel module is responsible for adding the parameters of a single digital in/output within a module.
- class qblox_instruments.qcodes_drivers.io_channel.IOChannel(parent: Instrument | InstrumentChannel, name: str, io_channel_idx: int)[source]#
Bases:
ComponentThis class represents a single IO channel. It combines all IO channel specific parameters and functions into a single QCoDes InstrumentChannel.
- __init__(parent: Instrument | InstrumentChannel, name: str, io_channel_idx: int)[source]#
Creates a IO channel class and adds all relevant parameters for the IO channel.
