Stefan Ritt | Peak at 0 mV in traces | The DRS chip is read out with a 12 bit
ADC, thus the phyical resolution is roughly
1V/4096 = 0.24 mV. I say roughly since the |

following your example, we tried
to perform the same measurement, using drs_exam |

Stefan Ritt | confusion about the description in drs.cpp | The locbus_addr is indeed 32 bits wide,
since the firmware was originally derived
from some firmware running in a VME crate, |

When you change the input range, you have
to redo the voltage calibration. Best is |

Stefan Ritt | Voltage and Timing Calibration in drs_exam.cpp | Have you set the sampling frequency

before the calibration? |

Stefan Ritt | Peak at 0 mV in traces | I note that your peak at zero is exactly
twice as high as the bins left and right,
so this looks to me like a binning problem |

Stefan Ritt | DRS4 using drs_exam.cpp to save as binary files | You have to write the C/C++ code yourself
to write data in binary or any other format.
All information is present after the waveform |

the waveforms in your user code, but can
rely on the DRS.cpp library to do that. Just |

Stefan Ritt | ROI | The DRS4 has an internal storage of 1024
capacitors. They work as a ring buffer, so
at 5GSPS you can store 200ns wide signals. |

in ns. So for 5 GSPS, the time scale goes
from zero to 200. Concerning your other issues |
