This paper reports on the comparison of two Josephson arbitrary waveform synthesizers for frequencies up to 500 kHz. Both independent pulse-driven Josephson arrays produce a 10 mV RMS sinusoidal voltage. They are alternately connected to an analog-to-digital converter which serves as a transfer standard. The setup is capable to of synthesizing quantum-based waveforms using two different pulse-bias techniques. We use the Zero-Compensation method and a two-pole high-pass filter structure in the pulse-bias configuration of one system (the reference) to minimize the amplitude error for signal frequencies up to 500 kHz. Consequently, we are able to directly detect the high-frequency voltage errors in the other system (the device under test). The setup is used to measure differences between both systems, and the influence of parameter variation on the results with Type A uncertainties of 0.4 µV/V ( k = 1) in measurement times of 60 s. We find that the dominant sources of deviati...

Josephson任意波形合成器中高频电压误差的测量和分析

本文报告了两种针对频率高达500 kHz的约瑟夫森任意波形合成器的比较。两种独立的脉冲驱动约瑟夫森阵列均产生10 mV RMS正弦电压。它们交替连接到用作传输标准的模数转换器。该设置能够使用两种不同的脉冲偏置技术来合成基于量子的波形。在一个系统（参考）的脉冲偏置配置中，我们使用零补偿方法和两极高通滤波器结构来最大程度地减小信号频率高达500 kHz时的幅度误差。因此，我们能够直接检测另一个系统（被测设备）中的高频电压误差。该设置用于衡量两个系统之间的差异，并且在60 s的测量时间内，参数变化对A型不确定度为0.4 µV / V（k = 1）的结果的影响。我们发现违规行为的主要来源...
