I am using a Basler Sprint line camera: spL2048-70km and PCIe-1429 framegrabber. I want to acquire images at 50 fps and would like to trigger each line. Accordingly I am providing pulses at 50 KHz as the trigger and am using a modified version of the LL Triggered Ring with the IMAQ configure trigger3 VI set to 'trigger each line (linescan)'. My problem is that the image starts at a different location each time I start the acquisition. Also, the image keeps moving up and down. Can anyone tell me how to solve this problem? I am attaching the VI and a snapshot of the image.
