This paper deals with a preliminary design of an electro-optic system for accurately measuring the phase of sinewave signals output by generators up to 100MHz. In particular, a short description of the measurement method and an envisioned application, namely the characterization of waveform recorders, is provided. In the paper, an initial selection of the commercially-available instruments, which are suitable for implementing the proposed electro-optic system and the chosen specifications, are shown. To estimate the repeatability of the phase measurements according to the main characteristics of the chosen equipment, a simulator was implemented and its description is available in the paper. According to the simulation, a maximum standard deviation of 0.028◦ can be achieved at 100 MHz.

Abstract
This paper deals with a preliminary design of an electro-optic system for accurately measuring the phase of sinewave signals output by generators up to 100MHz. In particular, a short description of the measurement method and an envisioned application, namely the characterization of waveform recorders, is provided. In the paper, an initial selection of the commercially-available instruments, which are suitable for implementing the proposed electro-optic system and the chosen specifications, are shown. To estimate the repeatability of the phase measurements according to the main characteristics of the chosen equipment, a simulator was implemented and its description is available in the paper. According to the simulation, a maximum standard deviation of 0.028◦ can be achieved at 100 MHz.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
