| Abstract: | In order to improve the precision of timing/frequency-calibrating for users, we improved the method of measuring the timing-delay of the long wave timing receiver system using the phase-shifting technique, high-precision digital storage oscilloscope and high-precision counter, so as to obtain a measurement with better precision than before. |
