Javier Caravaca | Trigger multiple boards independently | Thank you Stefan. Actually I noticed that the
source code of drs_exam was available after
I started this thread, and that was the solution |

Stefan Ritt | Trigger multiple boards independently | I'm not sure if the rate would go up
to 2 kHz (not 2 GHz!). Depends how the USB
hub is designed. What you can do however |

recently. It goes high on a new trigger,
but then STAYS high until the board has been |

Matias Henriquez | Trigger OUT pulse width variable from 100 us up to 100 ms | Given this new scenario, what is the maximum
rate of events that can be processed then
(a rough estimation would be great, 1/2ms?)? |

Stefan Ritt | Trace Impedance | The requiremnet is the same as for any
high speed analog board, there is othing
special with the DRS4. If you want to terminate |

Ismael Garcia | Trace Impedance | When you're refering to laying a 50
Ohm trace, you're referring to the SMA
input and not the interface between the output |

Stefan Ritt | Trace Impedance | The DRS4 input is high impedance. So if
you like you can terminate it with 100 Ohm
differentially and route it with 100 Ohm. |

Stefan Ritt | Timing diagram of SROUT/SRIN signal to write/read a write shift register | Dear Seiya,
1) That's correct. SRIN is
ampled at the falling edge. Pleae make sure |

Stefan Ritt | Timing diagram of SROUT/SRIN signal to write/read a write shift register | This is a static shift register, so you
can make the clock as slow as you want. Actually
I don't use a "clock", I just |

Stefan Ritt | Timing Issue | That's not a bug, but a feature of the DRS4
chip. The time bins have different values
by the properties of the chip. They are generated |
