Hi,
while trying to create python bindings for the DRS stuff using SWIG 2.0.4, two undefined methods prevent the python interpreter from loading the
generated shared library. These methods are: |

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 |

The web page from where you downloaded the software contains a sentence "requires libusb-1.0 package". Please install it. This package brings
the "usb.h" header file.

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? |

Best is to read this paper: https://arxiv.org/abs/1405.4975
The source code for that is in DRS.cpp in the DRS software distribution in the function DRSBoard::CalibrateTiming()

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.

Mon Jul 20 09:25:38 2015, Chenfei Yang, Measure the time between different samples
|
Hi,
I have a question using a data acquisition card base on DRS4 chip. How can I measure the time between several samples of one channel，with the
accuracy of like nanoseconds , for I am using the internal trigger. Is there any complete work about this problem？

|
Dear all,
I have been wondering what the maximum analog input voltage for the DRS4 V5 evaluation board is. It came with a sticker indicating that it is
"2.5V pk Max". On the other hand, when checking the manual (https://www.psi.ch/drs/DocumentationEN/manual_rev50.pdf), it says maximum allowed |
|

In principle the numbers in the manual are correct. But they relate to pulses of a certain length, because the input protection only works for DC voltage
and for pulses which are not too long. Since we could not write this all on the label of the board, we decided to put there 100% safe value as a "warning"
to people, meaning that if pulses are above 2.5V, they should look into the manual and read the details. |

Thank you! That solves my problem.

I'm troubleshooting a board which uses the DRS4 and adopts an analog front end very similar to the evaluation board. As a result, we rely |

I updated the picture in the manual with a current picture of a Rev5.1 board, and also added a picture of the bottom side. If you need a picture without
the blue labels, have a look at https://www.psi.ch/drs/old-evaluation-boards at the bottom.
Here is the explanation of the optional components: |

I don't believe I fully understand how the timing works between multiple channels on DRS4 board, even after reading the manual, but I am hoping to
measure a time difference between two channels longer than 1024/sampling rate. So far, I have written a program in Matlab to extract timing and voltage
information from the binary file to find the time difference between two channels that are set with the AND trigger logic and appear within approximately |

You cannot measure times longer than 1024/sampling rate.

|
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
Thanks,
