SetPhase
class qiskit.pulse.instructions.SetPhase(phase, channel, name=None)
Bases: Instruction
The set phase instruction sets the phase of the proceeding pulses on that channel to phase radians.
In particular, a PulseChannel creates pulses of the form
The SetPhase instruction sets to the instruction’s phase operand.
Instantiate a set phase instruction, setting the output signal phase on channel to phase [radians].
The class qiskit.pulse.instructions.phase.SetPhase is deprecated as of Qiskit 1.3. It will be removed in Qiskit 2.0. The entire Qiskit Pulse package is being deprecated and will be moved to the Qiskit Dynamics repository: https://github.com/qiskit-community/qiskit-dynamics
