Session.connect_device(serial: str, *, interface: Optional[str] = None) → Union[BaseInstrument, HDAWG, PQSC, QHub, SHFQA, SHFSG, UHFLI, UHFQA, SHFQC]

Establish a connection to a device.

Info:

It is allowed to call this function for an already connected device. In that case the function simply returns the device object of the device.

If the interface is not specified the interface will be auto detected. Meaning one of the available interfaces will be selected, prioritizing 1GbE over USB.

Returns:

Device object

• KeyError – Device is not found.

• RuntimeError – Connection failed.
