by Oscilloscope,one question is that i set 200V&&it said that is 206Vmeasured ，but on the screen is 6V ,as shouter said that 20:1,it is not enough,and one thing more,how can i pulse a programable pattern wave when i use the outside trigger?i tried set the pattern wave but it only worked with the “p” command
can i control the timing when i use the
outside trigger?
