Dear Stefan Ritt,
Yes I use Windows 7, If the DRS Oscilloscope program stays on for a couple of hours without saving the
data, the problem will occur. It seems it happens more often when there is data writing and when the rate of events is slow, about 100 events per second, |

At hight rates I worked with files of up to 20 GB so I don't think this is the problem.
I will try to run it under Ubuntu and see if i can recreate the problem.
Thank you very much for the quick responses and help. |

 Wed May 13 00:52:51 2015, Cosmin Deaconu, Getting Trigger Source
|
I'd like to be able to know which channel (0,1,2,3 or external) was responsible for the trigger. DRSBoard::GetTriggerSource() seems to always
return 1. Is there a way to get this information? Using the DRS4 evaluation board and software version 5.0.3.
Thanks, |

|
I am trying to use 4 evaluation boards with a powered USB hub (since eventually, I will have to do this on a laptop). It seems like destroying
the DRS object is insufficent to properly close the boards when on the hub (i.e. I get usb read errors next time I run my program). When all the boards
are plugged into the computer, all is fine. This is on Linux using libusb1. My guess is something about resetting the port doesn't work properly |

Hello everybody,
I am completely new to this, so please bear with me.
I am trying to install the applications on my laptop. I downloaded and untar-ed the drivers and applications for Linux as described in the evaluation |

Thank you Stefan, that was just what I needed.
Also, I have another question, if I am allowed to ask on this forum. I am trying to study how the time calibration of the DRS is done. Can you
point me to the script in which this is done? |

Hi Stefan,
I have already read the paper. I was just unsure where the calibration code was located. Thank you so much for all your help.

Hello everybody,
I was trying to create a stand-alone program that would perform a time calibration on the board. My goal would be the following.

Hi Stefan,
Thank you for your reply. I have read the paper already. I looked through the code and I understand that the LTC and GTC are performed by the
AnalyzeSlope and AnalyzePeriod functions, respectively, correct? It seems to me to be a complicated business to re-write that part from scratch, at least |

Thank you for your help Stefan. I will try to get the TC part isolated.

Hi,
I would like to use the DRS4 board with LabView for fast readout.
Do you know anyone who has written a VI for that? |

Hi,
Is there a straightforward way to convert the xml file format into the binary format? I have some runs taken mistakenly with
xml. |

I am new to this forum. I have ordered a DRS4 evaluation board for doing experiments with very fast PET detectors. It has not arrived yet. The version
of the manual I downloaded today shows software installation instructions for Windows 7 and earlier versions. I intend to use it on a 64bit PC running
Windows 8.1. Will the Windows 7 driver work, or is there an updated version for Windows 8 or 10? |

I tried this suggestion of changing the startup settings to ingore driver license signing (as suggested in the post # 434), but when I tried to install
the software I got a error message which I captured from the screen and I have attached. Perhaps I have the wrong version, or, as suggested, the file I
downloaded from your site is incomplete? |

I tried restarting Windows 10 in a way the allowed me to use "advanced startup options" Option 7 suggested it was to restart without mandatory
driver signing. However, the error persists. Has anyone tested this latest version 5.0.4 on Windows 10? My hardware arrived today, and I am anxious to
test it.!!!! |

On a hunch, I tried downloading V 5.0.3 instead. This works, and I now have the oscilloscope mode displaying signals! (just to make sure, I re-tire version
5.0.4 and still get the same error. So, in summary V 5.0.3 seems to install successfully and work with Windows 10, but the newer V5.0.4 does not install...
I assmume that I am missing something though, as the newer version is 10 Mbytes bigger! |

Thu Jan 14 21:49:37 2016, Chris Thompson, Triggering of DRS4 in the fastest sampling mode
|
I am attempting to use the DRS4 to measure the timing resolution of a pair of SensL silicon photomultipliers (SiPM). In order to do this I need to trigger
the DRS4 only when there is a coincidence between the two input signals, and hopefully make histograms of the relative detection times of each detector.
There are two completely separate issues. (1) I think this may just be a labelling error. In the first image (OR_mode_selected) one can clearly |

|
I needed a fast pulse inverter in order to feed signals from the recent SensL SiPMs into a conventional CFD which only accepted negative signals. I got
a very small ferite torridal transformer from Coilcraft and wired up to invert signals then inserted into in 50 ohm coax cable and it works fine. These
things cost only a few cents each! |

The coilcraft part number is: JA4220-ALB. Iordered two of them and they were sent as free samples. You might want to buy some slightly bigger
ones. I found them so small it was very hard to solder the coax cable to the connectors. Since I got them, I managed to damage one as they are quite fragile!
In the confirmation email I got there was some contact info which may be useful for you: "For help, contact Victoria Berner |
