  * Identify missing parts
  * Improvement for bKAGRA
  * Other suspensions		   * We went through the cables for PR3.
   * Overview diagram was drawn on a white board (picture)
    * Blue double circles indicates cables to be replaced from the test hanging (because of wrong pin-out).
    * Red check marks mean we checked the corresponding cable
   * Missing parts -> nothing
   * Connection between an LVDT driver and an ADC required a gender changer. Against the general policy of KAGRA electronics, the output connector of the LVDT driver is male (output should be female in the policy). Therefore, a gender changer was necessary. We should add a gender changer at the output of the LVDT driver.
  * Future improvement
   * We need an overview schematic like the one drawn in the meeting with links to more detailed documents.
   * From the schematic, we should generate a table of necessary cables
   * We should use this table to check if we have all the necessary cables

Agenda

  • PR3 electronics diagram (Mark)
  • Discussion
    • We went through the cables for PR3.
      • Overview diagram was drawn on a white board (picture)
        • Blue double circles indicates cables to be replaced from the test hanging (because of wrong pin-out).
        • Red check marks mean we checked the corresponding cable

      • Missing parts -> nothing

      • Connection between an LVDT driver and an ADC required a gender changer. Against the general policy of KAGRA electronics, the output connector of the LVDT driver is male (output should be female in the policy). Therefore, a gender changer was necessary.

    • Future improvement
      • We need an overview schematic like the one drawn in the meeting with links to more detailed documents.
      • From the schematic, we should generate a table of necessary cables
      • We should use this table to check if we have all the necessary cables
