WaveformConstructor

This package helps on constructing the waveforms for the AWG.

Documentation: https://waveformconstructor.pages.dev/

Installation

One can install the package via setuptools:

python setup.py install

To install the package in develop mode instead, use:

python setup.py develop

Usage

Initialize default values

It is recommended to change the default values to the parameters you used in the experiment before constructing any waveform. The default values are stored in the dataclass WaveformConstructor.default.DefaultValues.

Example:

import WaveformConstructor
from scipy.constants import *

# Change the carrier frequency in the wavefrom construction to 200 MHz
WaveformConstructor.DefaultValues.carrier_freq = 200 * mega

One can also modify the default values before installation.

Examples

Ramsey Spectroscopy

import WaveformConstructor
from scipy.constants import *
import matplotlib.pyplot as plt


half_pi_time = 2.5 * micro # half pi time of the flopping.
amplitude = 1.0
frequency = WaveformConstructor.DefaultValues.carrier_freq + 1 * kilo # frequency of
phase = 0
ramsey_duration = 1 * 10 * micro # wait time of the Ramsey spectroscopy

waveform_series = WaveformConstructor.WaveformSeries(
    [half_pi_time, ramsey_duration, half_pi_time],
    [
        WaveformConstructor.CarrierFlopping(amplitude, phase, frequency),
        WaveformConstructor.Zero(),
        WaveformConstructor.CarrierFlopping(amplitude, phase, frequency)
    ]
)

print("total time of the waveform:", waveform_series.total_time)

# Evaluate the waveform
t, v = waveform_series.waveform(sampling_rate=int(625 * mega))


# Visualize the waveform
plt.plot(t, v)
plt.xlabel("time")
plt.ylabel("voltage")
plt.show()
