Hello, I'm using two DRS4 rev.5 boards for 8ch readout and triggering.
I needed to modify the trigger logic and implement some tweaks in the firmware, and noticed that

I presume you have several evaluation boards and want to run them in sync, right?
This can be either made in daisy-chain mode (see manual page 25). In this case only the master board can trigger the slave boards. If you need to trigger |

Hi Stefan,
No we only use one evaluation board. We use the evaluation board as a part of our beam test setup. It includes a telescope based on the current PSI46V2.1
CMS Pixel chip and a trigger logic board for triggering the telescope and the evaluation board. This includes a

Do the following:
Use the TRG OUT of the evaluation board as a "busy". Only if this signal goes low (meaning that the readout of the board is complete and the board has |

Actually we should take this offline not to pester other DRS users which are not interested in this topic. Please call me directly (3728) at PSI.

I'm also having trouble installing drivers and running DRSOsc program on another computer running Windows 8.
The issue with the driver is that it's not digitally signed. |

I fixed the described error. Can you try the new version from https://bitbucket.org/ritt/drs4eb/commits/80b3af753ed32eb365725f0f3244a4109347c01b

Hi,
I can't contact with Anita Van Loon about DSR4 chip's price and delivery.
Did you still sell it? Can you provide me this information? |

Just be patient. Anita is not at work this week.

Dear Sir or Madam,
Good morning，I am using drs4 chip, and the measured fDTAP == 1/350ns, that is, fDOMINO == 1 / 350ns * 2048 == 5.8GHz.
I have three questions: |
|
Mon Jan 3 17:13:41 2022, Stefan Ritt, DRS4 request assistance

1. fDOMINO is defined as fREFCLK * 2048
2. Good values can be derived from the evaluation board schematics: C1=4.7nF, C2=1nF, R=130 Ohm
3. A "1" means a logical high level. See Wikipedia: https://en.wikipedia.org/wiki/Logic_level |
