Re: DSO150 signal line problem

very sure UB is on Pin 8 /U5
but Output is a low positiv Voltage.
@jye1 from witch manufacturer is the ICL
I bought ICL7660SCBA Super Voltage Converter Intersil SO-8 1pcs

Re: DSO150 signal line problem

All settings have no effect.
Normally with the V Pos setting the signal line have to be in the middle.
I think now that is a hardware damage
Once It got 11 Volt for few seconds .
What can die first with an overvoltage?!

DSO150 signal line problem

Hello,
first the device works, but since few days the signal linie is at the top of the display.
I do not calibrate c3 or c5.
VPOS reset and trigger have no effect.
