Published by National Institute of Standards and Technology | National Institute of Standards and Technology | Metadata Last Checked: August 02, 2025 | Last Modified: 2022-04-26 00:00:00
Data for all measurements published in the manuscript "Bipolar Waveform Synthesis with an Optically Driven Josephson Arbitrary Waveform Synthesizer," which will be published in the journal "IEEE Transactions on Applied Superconductivity".https://doi.org/10.1109/tasc.2022.3167660All files saved as Python pickle files. General pickle file comments: 1) Pickle file dictionary keys provide detail about the measurement information saved in the file.2) Load pickle files in python using the following commands: import pickle as pkl dat=pkl.load(open('005JAWSspectrum.pkl','rb'))005JAWSspectrum.pkl Pickle file containing the data used to produce Figure 3b and "1 kHz sine" in Figure 3a. The 'Voltage' key contains the recorded output voltage of the synthesized waveform that was used in the spectral plot. The 'scope_samples_per_sec' key contains the information for determining the frequency bins in the case of 3a, or the time steps in 3b.RFoff008JAWSspectrum.pkl Pickle file containing the data used to produce "RF bias off" in Figure 3a. The 'Voltage' key contains the recorded output voltage of the synthesized waveform that was used in the spectral plot. The 'scope_samples_per_sec' key contains the information for determining the frequency bins.000JAWSmargins.pkl Pickle file containing the data used to produce the quantum locking range plots with respect to dc bias shown in Figure 4. The 'Voltage' key contains the recorded output voltage of the synthesized waveform that was used in the spectral plot. The bias offset in mA is given by dat['settings']['AWG_sweep_amp_mA']. The sweep frequency for the triangular waveform is given by dat['settings']['AWG_sweep_freq_Hz']fundTo6thHarm_m8195ampSweep_47mAlaser_695mAamp_1001pt_Nave2.pkl Pickle file containing the data used to produce the quantum locking range plot with respect to RF modulation amplitude / RF-AWG output amplitude shown in Figure 5a. The harmonics of the acquisition were saved in the 'harmonics' key in units of dBm.
