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. |

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 |

Stefan Ritt | transparent-mode voltage | There might be a solution. How do you bias
th input of the
DRS4 chip? If you use a scheme as described |

Stefan Ritt | transparent-mode voltage | To get the good linearity, you need indeed
ROFS = 1.05V. With a O-OFS of 0.9V, a zero
input signal would give you DRS_OUT+=1.05V |

Stefan Ritt | Peculiar behavior of time values for Rev5 DRS4 EB | First of all, you should not use new boards
with old software. I try to keep the current
software compatible with old boards, but |

and want to run them in sync, right?

Stefan Ritt | DRS4 Evaluation Board Osc Application | There is a horizontal position slider in
the "Horizontal" box on the right

the distribution does not contain
any binaries, since there are too many Linux |

Stefan Ritt | Creation of Object files | Anyhow it would be nice if you just post
your Makefile here, which runs with the standard
distribution, so people can use it if needed. |

oscilloscope traces for all your inputs and
