To ensure the traceability of Internet of Things (IoT) sensors and other electronic devices, there is a growing demand for the development of quantum voltage sources and the establishment of calibration techniques for small-voltage ranges. In this study, we conducted a precision evaluation of small-amplitude quantum AC voltage waveforms generated by frequency-modulated microwaves. The root mean square (RMS) values of the generated waveforms were measured using a thermal converter (TVC) and compared with theoretical waveforms reconstructed from pulse counts of the modulation frequency. This presentation discusses the influence of TVC measurement wait times and pulse count calculation methods on measurement accuracy, and reports on the optimization conditions and results of waveform accuracy verification.
