Hello again. I have not got evaluation board yet, but already faced some difficulties:) I'm trying to compile drs_exam.cpp on Windows 7 using dev-c++
with imagelib-2 and WxWindows 2.4.2 DevPaks installed, but nothing works. Compile log is attached. Honestly, I'm not very familiar with c++, so any suggestions
will be helpful. Thank you. |

I am trying to compile drs-exam, but am getting an error message I do not understand:

Hello,
I have designed four DRS4 chips (36 channels) on my board running at 1GHz (REFCLK=488.28KHz) and ROI mode. All 4 chips' REFCLK, DWRITE, RSRLOAD,
and SRCLK are buffer driven by the same source. SRCLK is set to 40MHz to reduce the readout time. |

Hi everyone,
I'm still looking through the forum for an answer to this question, but thought I'd go ahead and post anyway just in case it hasn't
been answered yet. If it has I can take this post down. |

|
Hello,
I recently acquired 4 DRS4 boards and I wanted to ask if it was possible to trigger them independently from the same computer.
I know that you can daisy-chain boards and trigger them all at the same time, but in my case, each of my boards record independent events, so |

Thank you Stefan. Actually I noticed that the source code of drs_exam was available after I started this thread, and that was the solution that
occurred to me too. I'll give that a try.
A related question is: if the 4 boards are triggering at max rate (500Hz), would the total data throughtput (of the four boards together) be |

Hello,
Is it possible to have different sampling rates in multi-board configuration? I tried using the scope application but I am unable to change
the sampling rate independently. |

I have a question about how to acquire the stop channel:

Thanks for your advice. The problem has been solved by setting the srin again while reading out from srout.

All I'm trying to do is cascade one input signal, though all available channels, so that I end up with 8*1024 bins per event.
Here is the read out on my board/chip: |

I cannot find the EVAL board using drscl version 5.06 while the drsosc works fine. I tried 2 different eval boards and 2 different computers and the
same effect. I looked under device manager at the libusb and the drs4 was there, and checked the driver which was found to be up to date. |

Dear experts,
We are trying to increase the event rate of the DRS4. We looked into the ROI
but couldn’t figure out how to run in ROI mode. We are wondering if there is pre-existing firmware for this? We also tried to download and build |

Hello Mr. Stefan Ritt
In DSR4 DATASHEET Rev.0.8 Page13, I noticed you metioned the samping should occur after
38 ns after the rising edge of SRCLK when the multiplexer is used. So what is suggested value(delay time between sampling and the rising edge of SRCLK) for |

Dear Mr. Stefan Ritt.
Thank u for your timely response on "DSR4 Full Readout Mode", I received it from Professor

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 |
