  • [摘要]:This paper presents improvements on a multi-channel time interval measurement for time standard assembly (TSA) developed within a certain project to measure the difference between the reference clock and system clock. The measurement design is based on a commercially available time to digital converter to provide a high-level resolution. The measurement has eight input channels plus a common channel and realizes common-start and common-stop operations. it can provide a maximum of 127 ps resolution per channel with the measurement range approximately 10 us. Furthermore, the measurement range can be extended to endless with a little decline of resolution per channel. The paper deals with details of measurement implementation and discusses the most important issues connected with converter application. The resolution variation of the measurements was analyzed and the architecture implementation details and the linearity plots are presented.
