A Phase Measurement Method to Guarantee the Traceability of the Calibration Systems

An electro-optic system implementing an accurate phase measurement method for sinewave signals

“…The calibration of waveform recorders (e.g., oscilloscopes) requires the utilization of well characterized (i.e., reference) signals at their input in order to obtain an accurate estimation of their frequency response [1]. According to the chosen type of reference signal, the utilized techniques, which are available in the literature, can be classified as [2]: (i) pulse-based and (ii) swept-frequency based.…”

“…An electroshock weapon characterization system consists of a long-epoch (e.g., 12s) and 200 MHz analog bandwidth for the waveform recorder to acquire both high voltage and current waveforms, simultaneously [4]. Preliminary hardware implementations of the phase measurement method [4] were described in [1] and [5]. In particular, a proof of concept was proposed in [1] with an arbitrary waveform generator, an oscilloscope and an universal digital counter.…”

“…Preliminary hardware implementations of the phase measurement method [4] were described in [1] and [5]. In particular, a proof of concept was proposed in [1] with an arbitrary waveform generator, an oscilloscope and an universal digital counter. An experimental assessment of the phase measurement repeatability in terms of standard deviation for sinewave frequencies ranging from 100 Hz to 10 MHz was published in [1].…”

“…In particular, a proof of concept was proposed in [1] with an arbitrary waveform generator, an oscilloscope and an universal digital counter. An experimental assessment of the phase measurement repeatability in terms of standard deviation for sinewave frequencies ranging from 100 Hz to 10 MHz was published in [1]. The reported results exhibit maximum standard deviations of 0.009 • for both 100 Hz and 10 MHz, [1].…”

“…An experimental assessment of the phase measurement repeatability in terms of standard deviation for sinewave frequencies ranging from 100 Hz to 10 MHz was published in [1]. The reported results exhibit maximum standard deviations of 0.009 • for both 100 Hz and 10 MHz, [1]. However, this implementation is limited to characterize only arbitrary waveform generators with two output channels synchronized to each other and to a maximum sinewave frequency of 10 MHz.…”
