libsigrok now supports the LeCroy X-Stream series of oscilloscopes (and possibly others).
This includes models from the WaveAce, WaveJet, WaveSurfer, and WaveRunner series in theory; some models may also be manufactured/rebranded by Atten, Iwatsu, or Siglent.
All these devices seem to use a common SCPI protocol and LeCroy's common waveform template format, so they should all work in theory.
Testing and/or patches fixing implementation details to support more models are highly welcome!
The code was contributed by Sven Schnelle, thanks a lot!
