hello everyone,
the interface of my oscilloscope(agilent dso 7012B) is blocked, when i change the input channel amplitude from high voltage to low voltag (from 1 v to 30mv ) without changing the vertical range to 0.019 v .(so i'am obliged to set the vertical range to 0.019 to run correctly the interface ).
notify that when my interface is blocked the icon of "trigd?" flashes in the screen of the scope .
i'am tried to change the level of trigger edge to low value (0.1,0.001,0) but he problem is the same .
but when i change the input channel amplitude from low voltage to high voltage the program run correctly and he didn't block .
thank you :) :)
