Hello!
We're developing electronics based on the DRS4 to read out a breast PET scanner and our event rate will be quite high so we're concerned about
dead-time. with that in mind, I have a question regarding the mode of simultaneous writing and reading that is described in the DRS4 data sheet. |

We see quite some spikes in our DRS4 sampled data in FACT. We see different types of spikes:
single cell spikes, usually showing a large amplitude of 200mV
double cell spikes, usually only in the order of 20mV.
Even triple and quadro cell spikes are rarely seen.
The double cell spikes often occur as symmetrical double cell spikes mirrored |

Please find attached a simple ROOT based program (http://root.cern.ch) to decode binary data from the DRSOsc program. It assumes that all four channels
were recorded. If this is not the case, the program can be adjusted accordingly.
To use it, simply type (assuming that you have written a data file "test.dat" with DRSOsc): |
