Driver & License

HScope supports the following models which are recognized at the first connection as SainSmart DDS120:

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

Loto OSC482 device at the first connection is recognized as DDS120, then it need to be configured in the app settings as OSC482 device (General -> Hardware -> Model). Restart HScope to refresh the configuration.


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