1 get_gates_by_type(gate_type: str | stanza.models.GateType) -> list[str]

Get the gate electrodes of a given type.

1 get_contacts_by_type(contact_type: str | stanza.models.ContactType) -> list[str]

Get the contact electrodes of a given type.

1 is_configured() -> bool

Check if both instruments are configured.

1 _jump(
2     voltage: float,
3     pad: str,
4     wait_for_settling: bool = False
5 ) -> None

Set the voltage of a single gate

1 jump(
2     pad_voltages: dict[str, float], wait_for_settling: bool = False
3 ) -> None

Set the voltages of the device.

Parameters:

pad_voltages

dict[str, float]

A dictionary of pads and their voltages.

wait_for_settling

boolDefaults to False

Whether to wait for the device to settle after setting the voltages.

Raises:

DeviceError: If the control instrument is not configured.

1 _measure(pad: str) -> float

1 measure(pad: str | list[str]) -> float | list[float]

Measure the current of the device.

1 _check(pad: str) -> float

Check the current voltage of a single gate electrode.

1 check(pad: str | list[str]) -> float | list[float]

Check the current voltage of the device.
