Hey. Yes, the program is running as administrator. By the way, this is win10. Your drs_exam works fine. My drs_exam compiled wrote no board found. Maybe
this is a problem like in the post https://elog.psi.ch/elogs/DRS4+Forum/698. Maybe there were solutions to the problems?
Thank You |

Could be. Have you tried that elog:657

Hello. When compiling drs_exam, do you need to use a "static "version of usblib or a "dynamic" version?"The problem
with "no board found" is not solved. Thanks for your help. |

"dynamic" or "static" does not matter, as long as you don't use your program on another computer. I have no more idea about the
"no board found" problem. It works ok on all computers I tried at our lab.

I have a very similar problem, the command line doesn't work but the oscilloscope program does! Tried to fix it using Zadig driver update. Using
Windows 7....

Dear Mr. S. Ritt
i am Ms. student , am working with your DRS4 board to calculate the time of flight of the cosmic particle which passes
trough the hodoscope . i see the signals at scope , which is negative (i don't want to take positive side of the signal). |

Hello Mr. Stifan.Ritt
In the DSR4 datasheet, it is mentioned
that there is an additional buffer at each analog output, this buffer shifts the the differential range of -0.5V~0.5V to 0.8V~1.8V. Does it mean that this
buffer shifts a voltage of about 1.3V for the primary differential range?
Again for the differential |

Hi! Stefan:
when I change a new computer(win7,64bit),I meet a problem that the drscl app cannot found the board! It shows"USB successfully scanned,but
no boards found",but the drsosc runs well . when I connect to other win7*64bits computer,only one of them runs property! Is there any driver else |

This problem has been reported by several people, like elog:551
So far I could not solve it. On the computers at our lab it works find so I cannot reproduce and fix the problem. One suspicion I have is that
the underlying libusb library needs to be updated. You can try to install the newest version from their website at http://libusb.info/, but I haven't |

I have tried about 4 computers,only one worked fine.I truly want to know how others get this fixed,can you get in touch with them?

Hi
I want to use DRS4 to digitize 16 channels of signals. The width of signal is about 20 ns, with frequency of 50Hz. The time differences
between these 16 signals are not constant, arranging from 3us to 0. I am confused about this in some aspects. |

1. Simultaneous writing and reading is not possible with the DRS4 chip. The manual says differently on p. 14, but due to a bug in the chip waveforms
get clipped at the end if one does that. We hopt to fix this problem in a future version of the chip.
2. You can cascade 2,4 or 8 channels. If you cascade 8 channels and run at 1 GSPS, you digitize a window of 8 us. If you have 16 signals, you |

Hello Stefan,
some colleages told me a story, I was neither able to confirm nor find anything in the datsheet about. According to them:
For some internal reason of the DRS4, if the “stop capacitor” of the DRS4 is >= 767, the true stop channel is one |

I cannot confirm the story with the "stop capacitor > 767". It can be seen from your plots that the distribution of stop cells are even,
no holes or bins with double height.
There is an issue with cell 767, but this is when one tries to do simultaneous reading/writing to the chip. This does not really work as writen |

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. |
