The most important contribution of the recent research in measurement was that the measuring equipment is involved in the information processing and that instruments are actually specialized computer systems. Design of the instruments is seemingly a straight- forward task, however, complex measurement problems are ill-conditioned and knowledge- intensive. Considerable portion of the measurement related knowledge is in such problems heuristic and non-analytic in character. To evaluate it and to inject it into the measuring system design require symbolic approaches developed in artificial intelligence field. In con- sequence complex 'intelligent' measuring systems are coupled numerical-symbolic hybrid systems, with the knowledge intensive (expert) component cooperating with extensive nu- merical libraries. Such systems can even be embedded in other architectures designed for more abstract goals.

In this paper, the influence of clock jitter (for example phase noise) in synchronized measurement systems (signal generator+data acquisition) on the quality of the measurements is studied. Explicit expressions for the measurement errors are derived for sinusoidal phase noise. These expressions can be used to specify the required clock stability of data acquisition systems
