Reference

• 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

回路図JGWDocにアップロード済み

何ch必要か->100ch -> 24枚
8ch単位で一箱　12箱

回路はニケフ購入
箱詰めを考える->電源(18V)直結、インターフェース(要検討)、変調信号を中に入れる、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
テストピンが必要かどうか確認
