An Instrument for Accurate Measurement of Pulse Periods
Abstract
For some time there has been an operational need for a device to measure with an extremely high degree of accuracy the time interval between two pulses in a pulse train.Such a device should be capable of performing this operation over the pulse-period range from 50 sec to 50,000 sec, a range that includes low-repetition-rate loran pulses as well as high-repetition-rate radar pulses. Presently available multisweep pulse analyzers, such as the AN/ SLA-2, are potentially capable of indicating such pulse periods to within one percent of full scale at best. For certain purposes it is operationally desirable to measure pulse periods to within 1 sec regardless of the length of the pulse period. This specification dictates an accuracy of measurement to within 0.002 of the maximum period for the measuring equipment if it is to cover the specified range.
