Would it be possible to obtain the diagram of the VM205 oscilloscope card.
And does anyone know the usage of RV1.
Thank you and good day.
Hello @Hebus ,
The RV1 is for calibration => DC Adjust “gain”.
In principle, this should not be adjusted, since RV1 was adjusted from the factory during the test procedure.
Circuit diagram can be downloaded from here:
Thank you for your speed and your response.
Good day to you.
