摘要：

In this paper, the required measurement time to measure a transfer function with a specified accuracy is analyzed, The waiting time that is needed to balance the transient induced errors against the noise errors Is calculated. This allows one to decide under what conditions broad-band measurements are faster than stepped sine measurements.
