EUROMET supplementary comparison TF.TI-K1 Comparison of time interval (cable delay) measurement
Project Description
At the EUROMET meeting held in Ljubljana on 3-4 April 2003 an idea on timeinterval comparison was discussed. As most plausible solution, a cable delay measurement was selected. Werner Mache (BEV) suggested to produce three cables with different length, equipped with BNC female connectors and enclosed in a box. BEV is therefore responsible for providing the travelling standard. BEV was selected as a pilot laboratory, which is responsible for coordinating the schedule, collecting and analysing the comparison data, and preparing the report.
The selected travelling standard is a set of three cables of approximate lengths of
Measured quantity is time delay, defined as time from the pulse entering the cable to time when the same instance of the pulse appears at the output of the cable. Optionally, time delay using CW signal of 1 GHz can be performed.
