The SA-400F3 is a preamplifier for submicro-signal detection, which has been developed to assure noise reduction never before accomplished. The SA-400F3 is used to foster versatility as a sensor head amplifier or preamplifier for sensitivity improvement and noise reduction in analyzers and measurement instruments.

**Applications:**

-    Superconducting device in quantum computers
-    MCT (Mercury Cadmium Tellurium) sensor for infrared detection
-    Squid sensor for micro-magnet detection
-    High-temperature superconducting Josephson device for microwave detection
-    Electromagnetic sensor for MRI systems
-    Photodetector such as a photo-multiplier and photo-transistor
-    Improving sensitivity of lock-in amplifiers
