What is the best way to detect peak to peak voltage for the following waveform ?

Question

I have two channels of waveform train ( ie W1 & W2 ), each of them is of frequency 64KHz.
Each channel of waveform train consists of sinewaves of 64KHz of fixed amplitude, say 2 V pk to pk, running for 100 cycles, and then rest for 0.15 sec continue with a sinewave of 64KHz of another fixed amplitude, say 1 V pk to pk running for 100 cycles as well, and then rest for 0.15 sec. The above cycle considered as a complete waveform cycle.
The above complete waveform cycle repeat for 10 cycles and rest for 1.3 sec and repeated itself.
From the two simulated waveforms (ie W1 & W2), I need to detect and measure the peak to peak voltage of each of the 100 cycles sinewaves.
What is th
e best way to achieve that ?

Answer 1

The waveform is free running as described above, ie sinewave running at approximate 64 KHz for about 100 cylce at fixed amplitude, say 2V ( actual number of cylce unknown, could slightly more or sightly less, depanding on the machine ) then rest for approximately 0.15sec, another sinewave running at approx. 64KHz at fixed amplitude, say 1.5V ( actual number of cylce unknown, could slightly more or sightly less, depanding on the machine ) running for approx 100 cycles continue...then rest for approx. 0.15 sec .....the above waveform repeated itself and free running .....I would like to capture or trigger each of the 100 cycles sinewave (rest time of 0.15 sec between each approx100 cycles of sinewave) to measure the peak to peak voltage and st
ore them in array for analysis purpose....what is the best way to achieve that as I do not have time reference, I only know that the waveform is running at the pattern described above.
Thanks for your help !
