Hi satefan,
I did some debug on the DRSOsc program and saw that everywhere you used the function "IsBusy()", you used it with "SoftTrigger()", |

I have connected 3 signals to the DRS4 Evaluation Board V5 which look like this in the drsosc app:
Note that here I am sampling at 5 GS/s. Using this app everything works perfect. |

Unfortunately I have not idea what the problem could be. In principle the trigger should be independent of the sampling speed, since the trigger is only
made with a discriminator and a flip-flop. The hardware must be ok since you see the trigger with the oscillocope app. All you can do is to go through
the sorce code of the oscilloscope app, especially drsosc/Osic.cpp::ScanBoards(), SetTriggerLevel(), SetTriggerPolariy() etc. to make sure you do the same |

|
I have seen in the app that the trigger source buttons do something different than the "or" and "transparent trigger" buttons:
If I enable the setup from the right, i.e. OR in CH4 and "Enable Transparent Trigger" the app stops triggering. This is the configuration |

Sorry for the spam. Just want to let you know that I was able to solve the problem, it was all due to a `float` being casted as `int` in the Python binding.
Now it works like a charm.

Hello All,
Are there any design resources available for the WaveDREAM PCBA's?
Thanks In Advance, |

|
No. This is a proprietary design.
Best,
Stefan |

Stefan,
Oh, didn't realize that.
Thanks! |

I don't know if this question is already documented elsewhere.
I am developing a DAQ code for the DRS evaluation board, v4 for a test beam experiment. I link parts of the existing DRS code as a library.
To understand the effect of various flags used in calls to the functions DRSBoard::GetTime() and DRSBoard::GetWave(), I performed several tests |
