|
I would like to be able to trigger in this fashon: channel 0 > 0.1 and. channel 1< -0.1, because I have a positive and a negative signal.
Can DRS4 (5) Eval board do this kind of trigger?
Thanks! |

Ok, thanks! do you know an easy in-line inverter like mini-circuit or digikey? Can also redesign the detector I gues to produce
positive signals, just it might be easier if there was a simple inverter if you are aware of? thanks Abaz

Thanks, that looks just fine.

Hi Chris,
I am looking at Sensl SiPMs as well, can you send the part number from Coilcraft?
Thanks! |

Thanks again, this is very useful, just another question did you put any other passive elements in the circuit for inverting the signal
or just simply swaped the transformer connections?

Wed Apr 27 20:04:12 2016, Abaz Kryemadhi, Best settings for time measurements
|
I am studing some pulses that are about 200-300 ns wide and a rise time of few ns, which settings would be best for coincidence time
measurements?
In some preliminary work I found for 700 MegaS the time measurement is better without time calibration (in -0.05 to 1V) rather than with time |

Hello,
Is there a root macro for decoding binary data acquired with the newest software for single board or multi-boards daisy chained?
Cheers, |

The older root macro did not work for me for data acquired with the newest software.
so for the newest software and multiple boards, I modified the read_binary.cpp into read_binary.C for those who like to use the root macro, see
the attachment. |

Hi,
I have been collecting some date using the DRS4 board at a trigger rate of 10-20 Hz, I only need the timestamp and the amplitude,
is there anyway to select only these two live as the data comes in to be stored. |

Hello,
I recently modified the binary to ROOT convertor written by Stefan (https://midas.psi.ch/elogs/DRS4+Forum/361) so it can decode data taken
with any channel or set of channels on the DRS4. In the process of testing this modifed version for data taken on all 4 channels, I encountered problems |

|
Hello,
I am wondering why the code should be changed to i < sizeof(eh), since doesn't fread(&eh,sizeof(eh),1,f) return 1 in this scenario?
I've confirmed with a cout statement that this is the case, so this break condition will therefore always trigger as sizeof(eh) is 32 bytes. |

Hello,
I was running through a particular binary file containing data taken on all 4 channels of the DRS4 and printing out the value of the first time
sample for each channel (per event). While doing so, I noticed that some of these times were negative. For this dataset, channel 1 was chosen |

Thank you for the excellent explanation and diagram. This part of the code is now much clearer to me.
My other questions pertain to the "trigger cell". Firstly, what precisely does this mean? Moreover, how does the "trigger |

Hello,
I had forgotten to disable the turn off the power to the USB drive on Windows and DRS4 stopped triggering. Now, we are all on quarantine and
I am unable to reset the board to normal function. Are there any commands to reset the board remotely. I tried all of the default Windows based solutions |
