Hello everyone .
I have received an old HUNG CHANG 5502 20 Mhz , its working but it got some issues .
For example if i want to display a 6.5 volts sinusoidal waveform , the scope should display 6.5v * 1.42 , so if i choose 2v/div , i get 4.6 div , but in my case i get about 7 div witch is equivalent to an ac input of (7div*2v)/1.42 =9.85 v AC .
The scope's v/div regulator is ranging from 5v/div to 5mv/div , and on the same regulator there is another small regulator for each voltage/div , i tried to adjust it but no change .
The other issue on this one is that the wave form is displayed but with a lot of flickering .
