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.
