Title: Help finding schematic diagrams or service manuals for DSO2D15 HANTEK
Post by: crysti on March 31, 2022, 06:34:18 pm

After few hours of Power On wave generator stop to working.
Now have only DC component with 3,8V DC, whether the generator is on or off.
I tested, I have no signal on pins 21 and 22 from DAC902.
Who can help me with schematic for AWG part?

The schematics were done using reverse engeneering by pcprogrammer. A big work!
