DN-AM1000
The DN-AM1000 Series high precision, as the sensitivity dynamic signal amplifier independence of majority (Multi-channel) it will put in to the 19" rack case and it will be able to use and it is planned. The voltage signal which is output comes to become rate (GAIN) until 1~11000 boats, answer back frequency the maximum 100㎑, the Low Pass Filter is becoming at 10㎐~10㎑.
