hi,

                 I am trying to export a trigger and clock signal along with signal generation  using nifgen.. I tried to generate trigger signal and clock signal using nifgen export signal. But I no trigger or clock is coming out.  I need to use these signals for synchronizing acquisition of some signals using scope.. I attached my vi.. can u suggest correction for my vi

Hi,

                   I tried to use 5122 daq using ni scope for acquiring signal continuously. I attached the VI for this. But the is not fetching continuously.. To fetch continuously what are the modifications required?? Can anyone suggest?


                                                                            Thanking you,

Hi hoovahh,

               Sorry for my bad vi, that I posted. I graphed signals. signals are acquiring, but there is tilt in timing. Here I am using 6368 card for acquiring and generating signals. is this the problem of phase variation? I am using internal trigger also.

Hi,

            I am trying to find phase difference between two acquired signals. In this project I varies frequency of input voltage continuously using for loop and measure two output voltages corresponds to each frequency from my circuit. I need to find the phase difference between two voltages accurately. Here I used "frequency amplitude" vi.. but each time when I execute the program with same circuit for particular frequency, phase difference changes... Is there any other method suitable for this project to calculate phase difference... I attached my vi along with this post.

                                             Thanking you,

                                                    Manu

Hi Jordan, crossrulz, stagg

                   Thank you for your great reply.. Your help saved my time... I tried array subset method.. This is working fine in my case... Thank you all

Hi,

           I  am trying to acquire voltages from circuit. I got a waveform that I attached to this post. I just want signals from time .002 to .007 in that graph. For selecting particular sample, what will I do? I don't have enough knowledge in labvie... So please help me.

                   Thanking you,
