研究目的
Investigating the application of the AC Quantum Voltmeter for impedance ratio measurements at voltages up to 5 V and frequencies up to 1 kHz.
研究成果
The results show that for Fluke 5720A, standard deviation is limited due to the phase-lock principle applied. The output voltage of Aivon DualDAC2 is more stable with lower noise, but only with no change in connection, load or frequency.

1：Experimental Design and Method Selection:
The AC Quantum Voltmeter measures the RMS voltages on each resistor in a time sequence.
2：Sample Selection and Data Sources:
Two self-developed resistors of nominal values of 10 kΩ are used.
3：List of Experimental Equipment and Materials:
A calibrator Fluke 5720A and an Aivon DualDAC2 source are used as the AC voltage source.
4：Experimental Procedures and Operational Workflow:
The impedances are measured in a potentiometric way.
5：Data Analysis Methods:
The ratio R1/R2 is calculated as deviation in ppm from nominal value of 1.
