Subject: PDFR: List of DC transimpedances 

The following values are going to be entered in the param_[PDname].yml file for each PD. I am elogging them for future reference.

I got the values from combing schematics and old Elog entries. Please let me know if you believe the values are different.

  • AS55: 66.2 ohms
  • REFL11 : 66.2 ohms 
  • REFL33 : 50.2 ohms
  • REFL55: 50 ohms (Elog 4605)
  • REFL165: 50.2 ohms
  • POY11: 66.2 ohms
  • POX11: 50.2 ohms
  • REF (NF1611): 700 ohms
  • POP22: ?? (This is currently a Thorlab BBPD )
