Thats not a simple modification to my PCB, but I'll give it a try. Thanks for your help

I found the problem, and it had nothing to do with the CMOS clock input. As it turns out, even though I was using the default state of the config
register, I still had to write to it after powerup. Once I did that, the PLL locked immediately.

I'm writing the drs_exam.cpp to use multi-boards(v3, firmware:4.0.0), and taking data succeeded. But I have several questions about function written
in DRS.cpp.

|
Dear all,
I'm using 3 DRS boards simultaneously and their serial numbers are 2169, 2170, 2172 respectively.
Recently however, I obtain serial number "0" by DRSBoard::GetBoardSerialNumber() for #2172 board. |

The serial number has been fixed by using drscl. Thank you！

Hello,
I 'm using four evaluation boards v.3 to construct the multi-board DAQ system. One channel for each board is used as reference clock, then
calibrate timing offline, which allow below 10ps resolution between boards. |

Dear Stefan,
I am using an DRS4 board to record the signals from an plastic scintillator detector. It was working really good, yet a few day ago the signals
became "not right". When I checked the signal using an oscilloscope it show the normal signals previously recorded. The signal amplitude |

Hello!
I have a question concerning the sampling speed of the DRS4 evaluation board.
It is written in the manual that the sampling speed of DRS4 Evaluation Board is supported above 0.7 GHz. |

Dear Stefan,
Is there any way to develop LLD and ULD discrimination in DSR-4 evaluation board?
Best regards,

Hello.
I have a simple question, can I set SetTriggerDelayNs() more than 1631 ns? |

Dear Laura
You need to disable driver signature enforcement. Then try again with path option.
It helped me. |

Hello Stefan
I tried to convert binary to a simple txt file and found next problem - strange time output.
Here is output from little modification for read_binary.cpp (Its last output line also is strange: dT = -1.#IOns +- -1.$ps) |

Okay, it works with 5.05 version very good and it is enough for me.

Hi DRS4 Experts,
I have an extremely naive question: Is there any official macro to unpack the DRS4 binary files? All I am looking to do is to plot a few of my
waveforms and manipulate them in root. I am using OSX 10.10 and ROOT 5.34. |

I should of course mention that I looked through the DRS4 website and didn't see anything obvious: https://www.psi.ch/drs/evaluation-board
