QuSinus develops high-precision signal generators for use in laboratories at universities and non-university research institutes (e.g. in the field of quantum computing) and in industry (e.g. for the development of the next generation of telecommunications equipment). Precise signals play an important role in various applications, from measurement systems to radar and telecommunications. In telecommunications in particular, ever larger amounts of data have to be transmitted in ever shorter times. If the data transmission signals are not highly precise, communication errors will occur time and again. QuSinus signal generators are based on a new technology that achieves unprecedented precision, particularly in terms of phase noise, and thus enables progress in various applications.
