Avo HF134 signal generator

Rob, I would hazard a guess that you have not set your scope up sufficiently for it to trigger when it's sweeping. Try some adjustments, have you got it set to auto trigger. If you have not done the 2hour TEK course over on the other forum I fully recommend that you do, it is excellent and the TEK engineer is so easy to understand. At the end of it you will be a basic scope pilot
