2013/2/15 meeting (高橋、宮川、上泉)

  • 何ch必要か -> 100ch -> 基板24枚

    • 8ch単位で一箱 -> 計12箱

  • 基板はニケフから購入することを考える
    • 基板の箱詰めを考える
      • 安定化電源内臓のため、外部から18Vを直結
      • インターフェース -> 要検討

        • 位相ねじにフロントパネルからアクセス(穴をあける)
        • テストピンが必要かどうか確認
  • 変調信号出力を箱の中に内臓
    • 変調周波数は固定(TAMAの回路図参考)
    • 外部から変調周波数を入れるのも作っておく
  • 箱詰めした回路の完成8月完成を目処
