“…In several test procedures, sine-wave signal generators are adopted as sources of excitation for assessing the performance of waveform recorders [1], [2], [3], [4]. Those generators are often used to determine the magnitude and phase of the frequency response of waveform recorders (e.g., oscilloscopes) [5]. In this way, it is possible to compensate for the effect of the front-end on signal acquisition and to guarantee measurement traceability.…”

“…The synchronization between the pulse train signal and the sine-wave under test is obtained through a 10 MHz reference clock. The obtained standard deviations are in the order of 0.01 • at 5 • C for frequencies ranging from 100 Hz to 10 MHz, [5]. In the experimental setups used in [10], the standard deviation was assessed on 40 phase measurements by using a universal digital counter as a monitor to provide a coarse estimation of the phase.…”

This paper deals with the experimental characterization of an accurate phase measurement system using transmission lines as phase reference. In particular, the used prototype implementing the accurate phase measurement system is also described. The prototype characterization aims of assessing the repeatability of the phase measurement and identifying the systematic effects affecting them. Several transmission lines, priory characterized by means of a Vector Network Analyzer, have been used as phase references. The obtained results demonstrated the standard deviation increases with the sine-wave frequency, while systematic effects are clearly visible at 10 kHz and 100 kHz. The maximum obtained standard deviation at 10 MHz is 0.30 • .

To enhance the accuracy of phase measurement and to prevent tracking errors, it is crucial to effectively read the multi-frequency signal in space gravitational wave detection. In this paper, a novel signal acquisition method called the multi-frequency acquisition algorithm is proposed and implemented. Different from the traditional single-frequency acquisition, the signal characteristics of amplitude and frequency are both considered to better distinguish different frequency components. A phasemeter integrated with the acquisition method and narrow-bandwidth digital phase-locked loop is constructed for the method test and verification. The results show that the multi-frequency acquisition unit can capture all the frequencies of an input signal in several milliseconds. The precision is better than ±200 Hz under a low SNR (signal-to-noise ratio) of 0 dB. The phase noise can reach 2 µrad/Hz1/2 in the frequency range of 0.1–1 Hz and satisfy the requirement of the space gravitational wave detection in all frequency ranges.
