Stefan Ritt | Dtap stops toggling after 40msec |
I want to see the trace on the scope for the DTAP, the REFCLK, the DENABLE and the DWRITE.
Probably (but it's just a guess), you have a problem with the soldering of the DRS chip, maybe to the PLL loop filter. Or you chose the wrong capacitor/resistor combination for the loop filter. There are ~10 other groupsl who did the same and it works for all of them, so there must be a problem on your side.

my refclk is 1.25Mhz
what are the inputs and voltage you need to see?
Avdd and Dvdd are 2.5v
Denable is "1" Dwrite "0"
currently i am doing an external reset cycle, after that i am doing the configuration cycle.
should i relay on the internal reset?
the Dtap is toggling for 33.8msec and then just stops.
Thanks, Mony

Hi
the drs4 start to generate Dtap signal after reset and standard configuration.
while in reset Denable and Dwrite are low
after reset we put Denable in high
the Dtap starts to toggle, and the plllck stabilizes on about 1V.
After 40Msec the Dtap stops to toggle and the plllck go to 2.5V
Why do the Domino stop working?
Thanks, Mony

On a hunch, I tried downloading V 5.0.3 instead. This works, and I now have the oscilloscope mode displaying signals! (just to make sure, I re-tire version 5.0.4 and still get the same error. So, in summary V 5.0.3 seems to install successfully and work with Windows 10, but the newer V5.0.4 does not install... I assmume that I am missing something though, as the newer version is 10 Mbytes bigger!

I tried restarting Windows 10 in a way the allowed me to use "advanced startup options" Option 7 suggested it was to restart without mandatory driver signing. However, the error persists. Has anyone tested this latest version 5.0.4 on Windows 10? My hardware arrived today, and I am anxious to test it.!!!!

Perhaps I have the wrong version, or, as suggested, the file I downloaded from your site is incomplete?

Robert Adams | Saving histogram data |
I would really love to be able to save histogram data, though I have not been able to do this. I could take a screenshot and extract the data from an image, but would prefer to avoid this if there is a simpler way... possibly I have overlooked something obvious? Thanks very much for any advice or tips. |

Hi DRS4 Experts,
I have an extremely naive question: Is there any official macro to unpack the DRS4 binary files? All I am looking to do is to plot a few of my waveforms and manipulate them in root. I am using OSX 10.10 and ROOT 5.34.
Thanks in advance,

There is software for DRS4 board and positron lifetime measurement availiable. Still in beta but works. Its usable for measuring time between pulses in two or three channels and histogramming that time. (May be time of flight measurement should be tested too) Project code is here: http://sourceforge.net/projects/qtpals/. More about it is here http://iopscience.iop.org/1742-6596/505/1/012044/. Still tested only with v3 and v4 evaluation board, but should work with new callibration in v5 board too. |

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

I do not know exactly what you do, so it's hard to give an advice. All I can say that the DRS4 Evaluation Board from PSI allows time measurements between two channels in the order of a few pico seconds. You can download the software for this board from the DRS4 web site and
have a look how things are done.
The trigger position is not a good time reference, since the trigger position jitters by a few samples. So if you want to measure the time of a signal versus a trigger, you have to put this trigger in a free channel of the DRS4 and use that as a time reference.
Best regards,
Stefan |

Hi,
I have a question using a data acquisition card base on DRS4 chip. How can I measure the time between several samples of one channel,with the accuracy of like nanoseconds , for I am using the internal trigger. Is there any complete work about this problem?
One conceivable way is using an global counter in FPGA, but I'm wondering how to synch the counter with the DRS4 sampling.
Thanks.
