Hi
I have just installed DRS4, but when I try to view it from the USB it don't work. Why?

Hi
Did you copy the udev rule 41-drs.rules into /etc/udev/rules.d/ ?
Which operating system are you using? |

Is a 5 GSPS oscilloscope suitable for use with Silicon surface barier detectors?

Hello,
We are using DRS4 Rev.2.0 board.
We want to measure number of pulses generated by charge particle detector. These negative going analog pulses are very fast having rise time |

Hello All,
I am currently trying to figure out how to properly characterize the dead time of the DRS4 board. My most recent experiment to try and answer
this question involved using an external trigger that can range from 1Hz to 2MHz. I fed this trigger into the DRS4 and collected 1000 samples with no input |

XML is very slow to write, and you are probably limited by that. Switch to binary mode, which is much faster. You will see in the end a maximum rate
of ~500 Hz, and thus a dead time of 2ms, independent of the sampling speed. Note that you have only an evaluation board, which is optimized for ease of
use. If you develop your own electronics, and do optimized readout, you can bring the deadtime down to 30ns x number of samples + 2us, or 32us if you read |

That is extremely helpful! Many thanks. One more question; If I were to take inputs from 2 channels at once, would that scale the dead time to 64us
using your example?

For applications which are critical on the dead time, one typically uses one ADC per DRS4 channel, and thus the dead time stays at 32us. If you multiplex
two DRS4 channels into one ADC channel, then it goes to 32us.

Hi,
I`m trying to calibrate my DRS4 evoluation board to an input range of 0-1V but it doesn`t work.
1) First I tried to calibrate it with the drsosc (version 5.0.3) Software. The -0.5V - 0.5V calibration works, but during the 0 - 1V calibration |

1) I tried to cablirate a V5 board with drsosc 5.0.3 and it just worked fine for me. No idea what went wrong in your case.
2) The "found 4096 stuck pixels on this board" can be safely ignored. It comes from the fact that the standard evaluation board has
four cannels unconnected (the DRS4 chip has 8 channels, four are connected to in the evaluation board and four are unconnected). So the software sees |

I also use Ubuntu 14.04 LTS and for my V3 borad I have to use drsosc 4.x or ealier to perform the calibration.

Sure, for a V3 board you need a pre-V5 software, but I assumed Julien had a V5 board.
