I'm having trouble with my 5000 series scope consistently triggering. I have my trigger set at 200 mV and press the Single button and wait for the buffer to fill, then do my testing. The scope is getting a ready from an amplifier so I can see the output from it reach as high 2 V and it only triggers 7 times out of 10. Any suggestion on why it doesn't trigger 10 times out of 10?
Is holdoff set to more then the minimum?
