LVDT driver
D1201253 Test Circuit of Voice Coil Driver
D1201251 Presentation for MIF meeting
D1201255 LVDT-Actuator Driver Electronics
JGW-D1201467: LVDT and Voice Coil Drivers Electric Circuits (1/5/2013
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
- 基板の箱詰めを考える
- 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
