We report on the calibration of quantum-based radio frequency waveforms generated by a Josephson arbitrary waveform synthesizer system. We measure these waveforms using a vector network analyzer and calibrate them at 4 K using a custom-designed cryogenic on-wafer multi-line thru-reflect-line calibration kit and a two-tier calibration procedure. The signals tested in this work can be used as reference signals to calibrate measurement instruments with potential benefits in terms of accuracy and flexibility compared to the conventional methods.
