Extracting time from dynamic data

Good morning,

 

I am acquiring a voltage from a myDAQ system. Basically it consists of a sinusoidal 6000Hz pulse during 50ms repeating approximately every 5 seconds.

My objective is to get the exact time position of these pulses, in other words the time corresponding to each pulse.

 

I am using a Tone measurement of the dynamic data and, in case it finds a 6000Hz signal, get the time from the dynamic data and store it somewhere.

 

This works, but I can´t get the corresponding time. I am using the "Get Waveform Time Array" vi but it outputs always the same array, apparently the whole Time array.

I don´t want to use the ms timer as I am hoping to get a higher resolution of time (5 microseconds) from the 200KHz sampling.

 

I believe I am confused about waveforms andtime management. Do you have any idea?

 

Thank you,
