Loto OSC482 / SainSmart DS482
Sainsmart DDS120
Rocktech BM102

Models Supported

For Loto OSC482, all the submodels are supported, including the M one which is provided with its own Android app:

OSC482, OSC482D, OSC482F, OSC482H, OSC482L, OSC482M, OSC482S, OSC482X

Submodels are just supported in the main Oscilloscope features and not in the specific additional feature (for example signal generator).

First Time Configuration

Also the old SainSmart DDS120 and Rocktech BM102 at the first connection are recognized as LOTO OSC482 (new model). When they are connected to the phone then it need to be configured in the app Settings->Oscilloscope->Hardware (Model) as DDS120. Disconnect and reconnect the oscilloscope.


HScope supports the following models which are recognized at the first connection as LOTO OSC482:

  • Loto OSC482/SainSmart DS482 (it uses license Loto OSC482)
  • SainSmart DDS120 (it uses license SainSmart DDS120)
  • Rocktech BM102 (it uses license SainSmart DDS120)


SainSmart DDS120 / Rocktech BM102 devices are also supported by Sigrok.
