Performance and calibration of high-end impulse analysing systems

High-end digital impulse analysing systems are becoming more and more accurate and surpass the relevant standard. Various performance data such as amplitude resolution and sampling rate are carefully checked for their influence on final accuracy or improvements in connection with sophisticated signal processing. As important as technical performance are frequent calibrations, which are also influenced by the quality standard ISO 9000. However, frequent calibrations are an expensive procedure. To minimise cost and work, a unique channel insert system has been developed. This channel insert system allows for an easy calibration procedure and a continuous device availability at 60% of the cost of conventional continuously operational systems.
