Model LI5600
Lock-in Amplifiers that measure extremely small alternating signals hidden deep within noise, are used in a wide range of advanced research fields, including scanning probe microscopes, terahertz spectroscopy and spintronics.
NF's newest lock-in amplifier LI5600 series is 2-phase, 2-frequency digital lock-in amplifier that delivers a high level of stability with post-phase detection digital signal processing. The series covers all areas of key functionality required for increasing reliability when measuring very small signals, such as an outstanding dynamic reserve up to 100 dB, update rates up to approximately 1.5 M samples/s (LI5660/LI5655), and smooth, high-speed 16-bit amplitude resolution output response.
