First trial

Pre-digital

  • 手動スイッチをTTLの信号に置き換える
    • MC servoの改良

Length 信号の置き換え順序

  1. P-arm signal 置き換え ===
    • Vertex: whitening, anti aliasing, filterの整備
    • Per end: dewhitening, anti imaging filterの整備
  2. In-line signal to MC length 置き換え ===
    • Vertex: dewhitening, anti imaging filterの整備

long term measurement

  • power
  • temperature at vertex
  • humidity at vertex
  • dust at vertex

  • target

channel number

ADC 16kHz

  • MC REFL: (DC) = 1ch
  • MC Trans: 1ch
  • MC_F :1ch
  • LSC: (DC, RF) x2 = 4ch
    • Total 7ch

DAC

  • MC: 1 SUS x 4 coils = 4ch
  • IFO: 1 SUS x 4 coils = 4ch
    • Total 8ch
    • (Vertex 4ch, X end 0ch, Y end 4ch)
