1. Introduction
1.1 quTAG MC – state of the art time-to-digital converter
The quTAG MC – Multi Channel – is a time-to-digital converter that measures electric signals
and marks them with time tags. This stream of time tags can be used in various and versatile
applications – from measurements in the picosecond range up to an hour.
The universal time tagging method allows correlation measurements (cross-correlation, auto-
correlation), lifetime measurements (start-(multi)stop) and many more possibilities within one
measurement. The saved stream of time tags contains all information needed to reconstruct
every measurement and analysis performed.
