# qiskit.ignis.characterization.drag\_schedules
<Function id="qiskit.ignis.characterization.drag_schedules" isDedicatedPage={true} github="https://github.com/qiskit-community/qiskit-ignis/tree/stable/0.6/qiskit/ignis/characterization/calibrations/pulse_schedules.py" signature="drag_schedules(beta_list, qubits, pulse_amp, pulse_width, pulse_sigma=None, width_sigma_ratio=4, drives=None, inst_map=None, meas_map=None)">
Generates schedules for a drag experiment doing a pulse then the - pulse
**Parameters**
* **beta\_list** (*list of floats*) List of relative amplitudes
* **the derivative pulse** (*for*)
* **qubits** (*list of integers*) indices of the qubits to perform a rabi
* **pulse\_amp** (*list*) amp of the gaussian (list of length qubits)
* **pulse\_width** (*float*) width of gaussian (in dt units)
* **pulse\_sigma** (*float*) sigma of gaussian
* **width\_sigma\_ratio** (*int*) set sigma to a certain ratio of the width (use if pulse\_sigma is None)
* **drives** (*list*) list of [`DriveChannel`](qiskit.pulse.DriveChannel "qiskit.pulse.DriveChannel") objects
* **inst\_map** ([*InstructionScheduleMap*](qiskit.pulse.InstructionScheduleMap "qiskit.pulse.InstructionScheduleMap")) InstructionScheduleMap object to use
* **meas\_map** (*list*) meas\_map to use
**Returns**
A list of QuantumSchedules xdata: a list of amps
**Raises**
**QiskitError** when necessary variables are not supplied.
