Generates a staircase program in which the amplitude of a readout pulse is varied.
Schedule sequence
.. centered:: Reset -- RO_pulse[i] -- Acq[i]
Parameters
----------
readout_pulse_amps
amplitudes of the square readout pulse in Volts.
readout_pulse_duration
duration of the spectroscopy pulse in seconds.
readout_frequency
readout_frequency of the spectroscopy pulse and of the data acquisition in
Hertz.
acquisition_delay
start of the data acquisition with respect to the start of the spectroscopy
pulse in seconds.
integration_time
integration time of the data acquisition in seconds.
port
location on the device where the pulse should be applied.
clock
reference clock used to track the readout frequency.
batched
schedule to be run in batched mode in the hardware backend.
init_duration :
The relaxation time or dead time.
acq_channel
The acquisition channel to use for the acquisitions.
repetitions
The amount of times the Schedule will be repeated.
Notes
-----
This schedule can be used to verify the binning and averaging functionality of
weighted acquisition for readout modules such as a Qblox QRM or a ZI UHFQA.
Because of the overlap between the readout pulse and the integration window, the
change in readout pulse amplitude should show up immediately in the acquired signal.

Notes
-----
The control pulse is configured to be applied at the same frequency as the

weighted acquisition in combination with the synchronization between the readout
module (e.g., Qblox QRM or ZI UHFQA) and the pulse generating module
