years, I finally understand where the "symmetric
spikes" come from and how to fix them. |

Alec Shackleford | WIndows Connection problem with drs507 SOLVED | Thank you for this fantastic solution.
I had almost reinstalled windows 7 to see
if that would solve the issue! |

Stefan Ritt | Peak at 0 mV in traces | The DRS chip is read out with a 12 bit
ADC, thus the phyical resolution is roughly
1V/4096 = 0.24 mV. I say roughly since the |

following your example, we tried
to perform the same measurement, using drs_exam |

Stefan Ritt | Peak at 0 mV in traces | I note that your peak at zero is exactly
twice as high as the bins left and right,
so this looks to me like a binning problem |
