The high prices for usual desktop lock-in amplifiers mean that they are not as common in noise limited experiments as would be desirable. For this reason FEMTO designed a complete, easy-to-use and high performance lock-in amplifier expanding the reach of lock-in amplifiers into cost-sensitive applications.
The Series LIA-MV(D)-200 Lock-In Amplifiers are designed as stand-alone units which can be programmed both manually by front-panel switches and remotely by a digital interface. By using a PC with a standard digital I/O card all main settings for sensitivity, time constant and phase shift can easily be controlled. Therefore, the Series LIA-MV(D)-200 Lock-In Amplifiers are the ideal tool for integration into complex or automated test systems as well as for use as standard lab unit in cost-sensitive applications.
