Stefan Ritt | transparent-mode voltage | I see your point. Actually I will soon
have the same issue since we design right
now a board with an AD9637 using the transparent |

Chenfei Yang | transparent-mode voltage | Here's the problem. My external ADC
has 2Vpp differtial input voltage range.
And the common-mode voltage of the inputs |

Stefan Ritt | transparent-mode voltage | The ROFS signal has no effect in the transparent
mode, so you have to adjust O_OFS between
sampling and transparent mode accordingly. |

For DRS4 differential inputs
ranges form 500mV to 1100mV, with ROFS set |

Stefan Ritt | DRS4 Evaluation Board Baseline/Voltage Calibration | Sure, for a V3 board you need a pre-V5
software, but I assumed Julien had a V5 board.

Daniel Stricker-Shaver | DRS4 Evaluation Board Baseline/Voltage Calibration | I also use Ubuntu 14.04 LTS and for my
V3 borad I have to use drsosc 4.x or ealier
to perform the calibration. |

Stefan Ritt | DRS4 Evaluation Board Baseline/Voltage Calibration | 1) I tried to cablirate a V5 board with
drsosc 5.0.3 and it just worked fine for
me. No idea what went wrong in your case. |

Stefan Ritt | DRSBoard::SetTriggerSource | Your first assumption is correct, e.g.
source = 00000000'00000001
= 0x0001 ==> CH1 |

Stefan Ritt | Clock settings in daisy chain DAQ | The resolution coming from the sampling
rate goes into these numbers, but just marginally.
At 5 GSPS, you get a few ps reolution, while |
