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

A class representing a single instruction in an PulseQobj Experiment.

Instantiate a new PulseQobjInstruction object.

**Parameters**

- **name** ([*str*](https://docs.python.org/3/library/stdtypes.html#str)) – The name of the instruction
- **t0** ([*int*](https://docs.python.org/3/library/functions.html#int)) – Pulse start time in integer **dt** units.
- **ch** ([*str*](https://docs.python.org/3/library/stdtypes.html#str)) – The channel to apply the pulse instruction.
- **conditional** ([*int*](https://docs.python.org/3/library/functions.html#int)) – The register to use for a conditional for this instruction
- **val** ([*complex*](https://docs.python.org/3/library/functions.html#complex)) – Complex value to apply, bounded by an absolute value of 1.
- **phase** ([*float*](https://docs.python.org/3/library/functions.html#float)) – if a `fc` instruction, the frame change phase in radians.
- **frequency** ([*float*](https://docs.python.org/3/library/functions.html#float)) – if a `sf` instruction, the frequency in Hz.
- **duration** ([*int*](https://docs.python.org/3/library/functions.html#int)) – The duration of the pulse in **dt** units.
- **qubits** ([*list*](https://docs.python.org/3/library/stdtypes.html#list)) – A list of `int` representing the qubits the instruction operates on
- **memory\_slot** ([*list*](https://docs.python.org/3/library/stdtypes.html#list)) – If a `measure` instruction this is a list of `int` containing the list of memory slots to store the measurement results in (must be the same length as qubits). If a `bfunc` instruction this is a single `int` of the memory slot to store the boolean function result in.
- **register\_slot** ([*list*](https://docs.python.org/3/library/stdtypes.html#list)) – If a `measure` instruction this is a list of `int` containing the list of register slots in which to store the measurement results (must be the same length as qubits). If a `bfunc` instruction this is a single `int` of the register slot in which to store the result.
- **kernels** ([*list*](https://docs.python.org/3/library/stdtypes.html#list)) – List of [`QobjMeasurementOption`](/docs/api/qiskit/0.46/qiskit.qobj.QobjMeasurementOption "qiskit.qobj.QobjMeasurementOption") objects defining the measurement kernels and set of parameters if the measurement level is 1 or 2. Only used for `acquire` instructions.
- **discriminators** ([*list*](https://docs.python.org/3/library/stdtypes.html#list)) – A list of [`QobjMeasurementOption`](/docs/api/qiskit/0.46/qiskit.qobj.QobjMeasurementOption "qiskit.qobj.QobjMeasurementOption") used to set the discriminators to be used if the measurement level is 2. Only used for `acquire` instructions.
- **label** ([*str*](https://docs.python.org/3/library/stdtypes.html#str)) – Label of instruction
- **type** ([*str*](https://docs.python.org/3/library/stdtypes.html#str)) – Type of instruction
- **pulse\_shape** ([*str*](https://docs.python.org/3/library/stdtypes.html#str)) – The shape of the parametric pulse
- **parameters** ([*dict*](https://docs.python.org/3/library/stdtypes.html#dict)) – The parameters for a parametric pulse
