Hello, With this change you get a steady and steady voltage even if the 9V power source varies, while R26 and R27 give any voltage depending on the load and source voltage. ICL7660 produces noise on the negative line. The addition of the two regulators can only bring good and remove noise on the mea...

Hello,

The electronic card 109-15001-00C is also compatible with the latest firmware 061.

Hello, This provides a precise and stable 5 volt positive and negative voltage independent of variations in the source voltage. With a power supply from a 3.7V li-ion source with booster to get 9V, the voltages are rid of any pollution. The analogue channel is sensitive to power supply noise. Peaks ...

Hello, I also made a power supply with a Li-ion battery of 3200 mAh for GSM Galaxy J5. I will post the pictures of the modifications and the feed in this topic. --- The battery compartment is 9mm thick and is manufactured with double-sided epoxy printed circuit 15/10 welded with tin solder. It is he...

Hello,
To improve the supply voltage in the analog board of the DSO150 I replaced R26 by a regulator 78L05 TO92 and C11 by 100nf, and R27 by a regulator 79L05 TO92 and C14 by 100nf.
The GND pins of the regulators will be welded on C14 screen after having scratched the protective varnish.
