Suitable for nV order micro signal measurement
Fast response
Wide frequency range
Simultaneous 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.
