check time between 2 signals

[eeyc]

I need to check time(millisecond)  between 2 signals
The first one is look like sinus wave but after while it stabilize on zero(this is point of know specific state)
And the second wave is look like digital wave 10V and 0V and it synchronize according to the first wave.
Now I wont to check time between the first wave to second wave point zero to point zero(like Attachment example)
There is away do check it.
I use DQA to get those signals.

Tank’s for any help.

sorry forgot to Attach example

Hi Eyal,

So, I think you'll want to use one or more VIs from the Signal Processing Palette. THis can be found on your Block Diagram»Functions Palette. You should be able to use one of those VIs or set up a testing situation to determine when the signal is zero and at what point the signal is zero. You could then compare the times. You might want to take a look at the Pulse and Transition Measurements example. In LabVIEW go to Help»Find Examples...»Browse Tab»Analyzing and Processing Signals»Pulse and Transition Measurements»Pulse and Transition Measurements VI.

Yes, My requirements also bit similar. I want to measure the time taken between two points (Please refer the image), I'm doing the data acquisition through USB 6009

Could you please help me to measure the time taken between mentioned points. I need it in millimeter accuracy
