Hi all,
i'm an electronics engineering student at UCM (Madrid) working on my master's thesis within the CTA collaboration. I'm designing the readout electronics
for the telescope's camera, and i'm focusing in using GAPDs instead of PMTs and using the domino chip for the sampling of the signal. I was wondering if |

Thank you for your answers,
Another question : Have you ever tried to split the differential signal at the output of the DRS4 chip ? For
example to feed both an AD9222 and a diff. amplifier (followed by discriminators) ? |

|
Hi,
I wish to interface the DRS4 with the 8-channel ADC AD9222 (or AD9637).
I'm reading from the DRS4 datasheet that "the analog output of the DRS4 chip has been designed to match directly the input of the AD9222". |

Dear Stefan,
I am trying to setup DRS inside radiation enclosure and would like to write a simple script that will automatically save certain number of events.
Could you please point to me an example that can I use for Mac OS? I saw there is drs_exam.cpp in the directory but was not able to get work |

Dear Maksat,
If your car does not run, and you call the car dealer and tell him "my car does not run", what will the car dealer ask you? Eh... ?
Right ! He will ask "what are the symptoms, what did you try, what did and what did not work". Here it's the same. "was not able to |

I am having a general problem getting read back using the ROI mode. In the transparent mode everything looks good. These are the steps that I take:
1) configure register (b"11111111",addr = "1100")
2) configure write shift register (b"11111111", addr = "1101") |

Uhh, there are 1000 things which might be wrong. A bit like "my car is not working, it makes strange noise". Without having a look under the
hood, there is just some wild guessing:
- Is your ROFS input at the right value? Your O-OFS? |

Thanks for replying Stefan.
I was more so just concerned with the steps in the firmware when I had asked. However, yes the ROFS (1.05V) and O-OFS (0.9 V was 1.3 V earlier
but, changed this becasue of ADC input requirements) are per spec, the VDD voltages are all there and input voltages are within the rails and finally the |
