# UchannelLO

*class* `qiskit.providers.models.UchannelLO(q, scale)`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.3/qiskit/providers/models/backendconfiguration.py#L146-L210)

Bases: [`object`](https://docs.python.org/3/library/functions.html#object)

Class representing a U Channel LO

### q

Qubit that scale corresponds too.

### scale

Scale factor for qubit frequency.

Initialize a UchannelLOSchema object

> **Deprecated since version 1.2**
>
> The class `qiskit.providers.models.backendconfiguration.UchannelLO` is deprecated as of qiskit 1.2. It will be removed in the 2.0 release. The models in `qiskit.providers.models` are part of the deprecated BackendV1 workflow and no longer necessary for BackendV2. If a user workflow requires these representations it likely relies on deprecated functionality and should be updated to use BackendV2.

**Parameters**

- **q** ([*int*](https://docs.python.org/3/library/functions.html#int)) – Qubit that scale corresponds too. Must be >= 0.
- **scale** ([*complex*](https://docs.python.org/3/library/functions.html#complex)) – Scale factor for qubit frequency.

**Raises**

[**QiskitError**](/docs/api/qiskit/1.3/exceptions#qiskit.exceptions.QiskitError "qiskit.exceptions.QiskitError") – If q is \< 0

## Methods

### from\_dict

*classmethod* `from_dict(data)`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.3/qiskit/providers/models/backendconfiguration.py#L177-L189)

Create a new UchannelLO object from a dictionary.

**Parameters**

**data** ([*dict*](https://docs.python.org/3/library/stdtypes.html#dict)) – A dictionary representing the UChannelLO to create. It will be in the same format as output by [`to_dict()`](#qiskit.providers.models.UchannelLO.to_dict "qiskit.providers.models.UchannelLO.to_dict").

**Returns**

The UchannelLO from the input dictionary.

**Return type**

[UchannelLO](#qiskit.providers.models.UchannelLO "qiskit.providers.models.UchannelLO")

### to\_dict

`to_dict()`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.3/qiskit/providers/models/backendconfiguration.py#L191-L201)

Return a dictionary format representation of the UChannelLO.

**Returns**

The dictionary form of the UChannelLO.

**Return type**

[dict](https://docs.python.org/3/library/stdtypes.html#dict)
