frequency_offset(frequency, *channels, compensate_phase=False)¶
Shift the frequency of inputs channels on entry into context and undo on exit.
from qiskit import pulse d0 = pulse.DriveChannel(0) with pulse.build(backend) as pulse_prog: # shift frequency by 1GHz with pulse.frequency_offset(1e9, d0): pulse.play(pulse.Constant(10, 1.0), d0) assert len(pulse_prog.instructions) == 3 with pulse.build(backend) as pulse_prog: # Shift frequency by 1GHz. # Undo accumulated phase in the shifted frequency frame # when exiting the context. with pulse.frequency_offset(1e9, d0, compensate_phase=True): pulse.play(pulse.Constant(10, 1.0), d0) assert len(pulse_prog.instructions) == 4
float) – Amount of frequency offset in Hz.
PulseChannel) – Channels to offset frequency of.
bool) – Compensate for accumulated phase accumulated with respect to the channels” frame at its initial frequency.
