capturing full signal-urgent

[blackbear]

Dear all, urgent advise on capturing full signal.I have build a simple model to measure the phase and amplitude of 2 incoming signal.My signal are of only 0.1 seconds and have Voltage of 2 V. I am using SCB 68 board.For some reasons my labview 8.5 either capturing half the signal or 3/4 of the signal and i realise that my labview need to be synchroize with my amplifer in order to capture the full signal.Can some 1 pls advise me if theres anything wrong with my model?

Hi I have just had a quick look at your code and I am unable to see what the issue is from that. You mentioned that you need to synchronize with your amplifier, can you elaborate on this? Is the signal that you are trying to capture a continuous signal or is it just a finite signal? If it is finite and only lasts for 0.1 seconds it may be that you need to put in a start trigger so that you start acquiring data at the correct point each time. Are you missing the beginning or end of the signal? Once I have some more information about your application I should be able to help you out. Regards
