Determine pulse sequence

Hello Community,


As a follow up to my previous post I am still working with analyzing the output signals from the atomic clock at WWVB, I have two (similar / not identical) 60 kHz receivers that produce 1 PPS ticks.


The beginning of each second is represented by the downward or negative-going edge of each pulse. I am able to measure the difference of the downward pulse between the two by a few milliseconds. My question is how to visually interpret which pulse occurred first? Does Ch1 pulse before Ch2 or vice versa? I'm looking for a visual cue or how to determine the pulse firing order.


Any assistance is greatly appreciated.
