Hi Stefan,
That is exactly what I'm looking for. Thanks again!

Wed Mar 14 00:38:15 2018, Will Flanagan, sub-ms precision timestamps?
|
Dear DRS4 community,
Is there a way to extract timestamps with sub-ms precision? The milliseconds of an event is clearly given when unpacking the header. I would
like to determine how far apart events are when they are within the same millisecond. |

Hi all,
When connecting the board and running the Zadig program, some Windows PCs may return "driver installation failed." I coudn't
find the solution from their download website. So I started the drscl first. Apparently it shows: Successfully scanned, but |

|
I am using a DRS4 Evaluation Board v5 and running the drsosc.exe version 5.06 on a Window 7 machine. I have performed the voltage and timing calibration.
With test pulses on channel 1 and 2, I collected binary data file with all 4 channels active sampling at 5GSPS.
Attached is a distribution of the bin_width vs. cell # for all the 4 channels. Note that there are few cells with bin_width < 10 ps. |

|
Using a test pulse split into two channels of the DRS4 Evaluation Board v5, I looked at the time resolution using a leading edge threshold.
The voltage and timing calibration was performed. One method (1) is to linearly interpolate between two points of the raw waveform that
is above and below the threshold (this is exactly the algorithm given in read_binary.c in the drs4 source distribution); and another (2) is to |

Just a follow-up update.
It turns out that I was using a cubic spline interpolation with smoothing. If I required the cubic spline to go through the sampled points, then
I obtained similar time resolution as the simple linear interpolation. |

|
Hi,
I'm running a LIDAR application that requires that every outgoing pulse be captured. My current setup firess sets of 20-50 pulses at
1 ms intervals, about 10 times a second, but only 10-20 pulses a second are captured. |

Hi,
I'm trying to do the same thing (get 1 channel with 8192 bins), but I'm having some trouble with it. When I call SetChannelConfig(0,
8, 1) as suggeted, I get output that looks like noise on all readouts. Could you please explain what is supposed to happen in this case? |

Hi,
The board is modified (and checks out with the DRSScope program). Could you please point me to the drs_exam_2048.cpp file? I can't seem to
fine the most up-to-date git repository.... |

Hi
I can't download the software for windows on this website 'www.psi.ch/drs/software-download', there is some mistake when i
click on download. |

Quick question - what type of connectors are used for the trigger and clock in/out on the v4 eval board? |

Mon Jul 14 19:03:05 2014, Yves Bianga, change cascading from 1024 to 2048 bins for each input channel
|
Hello,
I want to ask whether it is possible to modify a Evaluation Board 5.0 from 1024 to 2048 cells for each of the 4 input channels.
On
the rev50 manual at page 31 I found an option to connect the 4 unused channels by setting 8 solder bridges.

Hi,
I found an old thread regarding a fix for DOScreen.cpp for DRS-3.1.0, that fixes an "ambiguous overload problem." Currently when I attempt
to build the drs-4.0.0, I get this similar error: |

Hi,
Our group had previously heard that a "DRS-5.0" might be on the horizon and that it may have ethernet capabilities as well as 16-input
channels (we heard this when ordering the DRS-4). Is this still in the works and accurate information? If so, is there a rough estimate to the "release |

I want to measure the signal from PMT . But it is a current signal, should i just put a series resistance, or use a amplifier to convert it to voltage
signal before drs4?
Can you give me some advice ? |
