# PulseQobjExperimentConfig

*class* `qiskit.qobj.PulseQobjExperimentConfig(qubit_lo_freq=None, meas_lo_freq=None, **kwargs)`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.1/qiskit/qobj/pulse_qobj.py#L473-L489)

Bases: `QobjDictField`

A config for a single Pulse experiment in the qobj.

Instantiate a PulseQobjExperimentConfig object.

**Parameters**

- **qubit\_lo\_freq** (*List\[*[*float*](https://docs.python.org/3/library/functions.html#float)*]*) – List of qubit LO frequencies in GHz.
- **meas\_lo\_freq** (*List\[*[*float*](https://docs.python.org/3/library/functions.html#float)*]*) – List of meas readout LO frequencies in GHz.
- **kwargs** – Additional free form key value fields to add to the configuration

## Methods

### from\_dict

*classmethod* `from_dict(data)`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.1/qiskit/qobj/common.py#L41-L53)

Create a new QobjHeader object from a dictionary.

**Parameters**

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

**Returns**

The QobjDictField from the input dictionary.

**Return type**

QobjDictFieldr

### to\_dict

`to_dict()`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.1/qiskit/qobj/common.py#L33-L39)

Return a dictionary format representation of the OpenQASM 2 Qobj.

**Returns**

The dictionary form of the QobjHeader.

**Return type**

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