This allows select which dynamic variety will enable the unit to reach the conclusion on the fiber. Understand that the greater decline There is certainly while in the community, the more dynamic selection are going to be required. Be aware that a superior dynamic range specified at twenty µs does not guarantee a higher dynamic vary at short pulses—abnormal trace filtration could artificially Raise dynamic range at all pulses at the cost of a foul fault-finding resolution.
