Hi. Please help me with the problem I've tried it for a long time as long as by script or some other testing. It didnt work :((( I just use LA to record my digital signal like this: And I want to zoom in to the part that has signals, and ONLY EXPORT the data by this region. 1. How can I do by export data by just this region? Because it always export too many data up to GB size file :(( 2. By the way, is there any method to zoom the signal by select the part of signal? (using mouse wheel to zoom has less resolution :( Thanks for helping me solving my questions!!!! Thanks a lot!
