Thank you for your help Stefan. I will try to get the TC part isolated.

Than you can try to isolate the code. Note that different SCAs might work differently. Like the DRS4 has a channel-to-channel jitter which others might not. But you will see.

Hi Stefan,

Thank you for your reply. I have read the paper already. I looked through the code and I understand that the LTC and GTC are performed by the AnalyzeSlope and AnalyzePeriod functions, respectively, correct? It seems to me to be a complicated business to re-write that part from scratch, at least for an inexperienced programmer like me. It made more sense to try to isolate that part from the original DRS.cpp. Ideally, I would like to have a stand-alone program that would work on any SCA without references to the drs hardware specifics.

Hard to say. Timing calibration is quite delicate. If you start from scratch, better read this paper: https://arxiv.org/abs/1405.4975

If you try to extract the code from DRS.cpp, better read the paper, too. Probably it will not be possible to develop or extract the code without knowing how it works. 

Best,
Stefan

Hello everybody,

I was trying to create a stand-alone program that would perform a time calibration on the board. My goal would be the following.

- acquire  about 10k sinus waveforms

- write them to disk (also for later reanalysis)

- run the time calibration on the recorded data

- store the clibration results in a file / database

Being not an expert, my question here is the following. Would it be easier to try to isolate the time calibration part from the DRS.cpp source code or re-write entirely the code from scratch?

Thanks.
