- NF Lock-in Amplifier LI5660
Suitable for nV order micro signal measurement
Lock-in amplifiers can detect minute AC signals of nanovolts and nanoamperes, which is difficult with general-purpose measuring instruments.
Not only the basic performance for detecting minute signals, but also the dual frequency function that can measure two frequencies at the same time.
Therefore, lock-in amplifiers are used for cutting-edge research that requires minute signal detection such as semiconductor physical properties, quantum element evaluation, and terahertz wave measurement.
