Hello,
I'm using DRS4 evaluation board version4 in Linux (Scientific Linux 5).
Version4 software (drs-4.0.0) was installed without any troubles. |

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: |

Hi,
is there any (obvious) reason why it is not possible (or not indended) to repeat the time calibration of a DRS4 eval board several times. I get |

Hi,
the latest software drs-5.0.0.tar.gz fails to compile on my freshly installed SuSE 13.1 whereas the previous 4.0.1 is compiling out-of-the-box.

Hi,
we want to run two instances of our little DRS DAQ program but obviously the first instance started always claims all DRS boards for itself and
the other one exits with an error. The 2 boards used in the example below have the serial number # 2413 and #2414 and are v5 boards. |

Hi,
I would like to save the waveform in a .dat binary file using drs_exam.cpp.
I know the distributed software allows us to save as binary files with the save button, but I currently need to save multiple runs using |

|
Hi!
I'm using the DRSOsc program, and I have a question that I need a bit clarified;
When triggering using AND between two channels, am I then triggering on rising/falling edge of both channels, or on the actual values? |

Hi all,
i'm an electronics engineering student at UCM (Madrid) working on my master's thesis within the CTA collaboration. I'm designing the readout electronics
for the telescope's camera, and i'm focusing in using GAPDs instead of PMTs and using the domino chip for the sampling of the signal. I was wondering if |

Hi,
According to DRS4's datasheet, the random noise is 0.35mVrms. Is this the input equivalent noise voltage? It is computed over the 0-950MHz frequency
band? |

When you're refering to laying a 50 Ohm trace, you're referring to the SMA input and not the interface between the output of the Op-AMP(THS4508)
buffer
and the inputs of the DRS4(IN0-IN8). Is there a recommended diffential impedance for IN0-IN8? |
