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.
FEATURES
-
Single and dual phase
-
Rugged aluminum housing
-
BNC connectors for input and output signals
-
Working frequency 5 Hz up to 120 kHz
-
Phase shifter 0° ... +360°
-
Current and voltage input
-
Optional reference oscillator module SOM-1 available
LOCK-IN-AMPLIFIER AS A STANDARD
PROGRAMMING THE LOCK-IN MANUALLY OR BY COMPUTER
The Femto 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.
