Hi,
I have an old v2.0 board that I just upgraded firmware on using v4.0.0 download package which has a drs4_eval1.bit for v2.0 boards containing firmware
15158. So I would like to use the latest DRS Oscilloscope program, due to the faster acquisition speeds and advanced calibration techniques, however I |

I'm also having trouble installing drivers and running DRSOsc program on another computer running Windows 8.
The issue with the driver is that it's not digitally signed. |

Hi,
although I don't have a chance to test your code, it looks very similar to what I am using.

Dear Stefan,
I am working with others at UCLA on a custom made board built around the DRS4. We are in the process of writing firmware so I am adapting the
readout state machine from the evaluation board firmware. |

Dear Stefan,
Thanks so much for clarifying this. We made wait_vdd a parameter controlled by software and will try to experiment with it to find some compromise
between deadtime and the offset added by the droop in VDD. |

Hello, everybody!
I installed DRSosc and DRScl. Command line works normally (at least, it can "see" the board). But when I start the oscilloscope, I
have an error: "PLLs did not lock on USB board #0, serial number #...". In Info section I can see the board type = 9 (and in the error message |

The serial number is 2586. This board is about two years old, and it might be in use (but I do not know exactly).

Are there plans to add the drs software to github? (asking because I have users @ethz.ch that want to use it on debian,
thus I'm creating official debian packages of it, if license allows so, but talking to upstream (the developers) would be
much easier on github (or irc) than on this "DRS4 Discussion Forum".

Hi,
we were trying to implement an automatic way to calibrate our DRS4 both in voltage and in time (we have the V5 Evaluation Board). We started
from drs_exam.cpp and tried with the following lines: |

Hi,
we modified drs_exam.cpp to read all 4 channels from the DRS4 and apply directly the spike removal (taken from Osci.cpp) during the acquisition
phase. For test purposes, we don't save the data showing spikes and we focus on the data not having spikes (even if at the end we end up having triple |

Hi,
thank you for the quick reply. All the bins in the previous histograms have the same width. We also tried to plot the noise histogram for channel
2 with more bins (i.e. 1000, so that we can see almost discrete values), and the peak is still there. |

Hi Stefan,
following your example, we tried to perform the same measurement, using drs_exam and taking 1000 events. The results we obtained are in the plots
attached (both in log and linear scale). We tried two different binnings: |
