I am trying to make a coincidence between two channels without using a SCA. I have a Tek DPO 7104 scope where I have two PMT's connected. PMT1 is on channel 1 and PMT2 is connected to channel 2. I have my current vi setup to trigger on channel 1. I generate a waveform that has both channels in the waveform data. My goal is to make a comparsion between channel 1 and channel 2. If channel 2 is "similiar" to channel 1, then write to file. If the two channels are not similiar then do not write and go back and wait for another trigger. I am thinking of using the "index array" to extract each channel seperately. The next part would be to make a comparison somehow. I was hoping someone might have an example that would help me to accomplish this. I have been reading the post but I have not found an example that will assist me. I would really appreaciate some help.
