# AcquireChannel

*class* `qiskit.pulse.channels.AcquireChannel(*args, **kwargs)`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.1/qiskit/pulse/channels.py#L198-L201)

Bases: [`Channel`](/docs/api/qiskit/1.1/pulse#qiskit.pulse.channels.Channel "qiskit.pulse.channels.Channel")

Acquire channels are used to collect data.

Channel class.

**Parameters**

**index** – Index of channel.

## Attributes

### index

Return the index of this channel. The index is a label for a control signal line typically mapped trivially to a qubit index. For instance, `DriveChannel(0)` labels the signal line driving the qubit labeled with index 0.

### name

Return the shorthand alias for this channel, which is based on its type and index.

### parameters

Parameters which determine the channel index.

### prefix

Type: `str | None`

Default value: `'a'`

A shorthand string prefix for characterizing the channel type.

## Methods

### is\_parameterized

`is_parameterized()`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.1/qiskit/pulse/channels.py#L135-L137)

Return True iff the channel is parameterized.

**Return type**

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