Stefan Ritt | Compiling DRS-exam | I guess you are compiling under MS Windows
??? You probably don't link correctly
to the USB lib. Try to compile the examples |

Stefan Ritt | baseline shift | The baseline shift comes from some instable
power supply inside the evaluation board
which cannot be controlled to the mV level. |

Stefan Ritt | two DRS4 boards configuration with 2048 samples each | The multi-board mode has never been tested with
2048 samples, so is very likely not to work.
I don't know yet how much work this will |

Stefan Ritt | | Yes this is correct. But it is a sample-and-hold
circuit. So the sampling cell follows the
input for 3.2 ns, then samples and holds |

Stefan Ritt | Trigger on the And of a positive and negative signal | No. You have to use an inverter for one
of your signals.

Stefan Ritt | DRS Oscilloscope freezing after a long run | I tried this night to run the board at
