Today I spent some time unplugging and rebooting a = DSO because I couldn't get the input to change from DC coupled to AC. Afetr= determining that the scope was faulty and fetching another I started going= through all the set up process again, when I got to the trigger menu I rea= lised that I had been switching the trigger from AC to DC and not the input= signal! Fortunately I didn't get as far as sending the original back for r= epair. regards James =20 --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
