LIA-MV-150-S Single-Phase X-Channel Low-Frequency 45kHz Lock-in Amplifier Module
The LIA-MV-150-S is a low-frequency single-phase lock-in amplifier module manufactured by the German brand FEMTO. It features BNC connectors for input and output, operates on ±15V power supply, and can be configured with the PS-15-25-L power adapter.
LIA-MV-150 Lock-in Amplifier Module
Operating frequency up to 45kHz
Current and voltage inputs
Adjustable sensitivity, time constant, and phase
Local and remote gain control
Compact modular design
Amplifier settings, such as phase, gain, and time constant, can be controlled directly on the amplifier module or externally using a standard digital I/O computer board switch. The variable operating frequency is determined by an external reference signal, such as the synchronization signal of a chopper or the modulation signal of a laser. The current input is well-suited for amplifying signals from high-impedance sources, such as diodes and PMTs, while the voltage output can be used to measure low-impedance sources like pyros or coils.
The miniaturized lock-in amplifier LIA-MV-150-S operates reliably and powerfully, even in extremely noisy environments.
