500 kHz / 5 MHz Lock-in amplifier MFLI
The MFLI digital lock-in amplifier from the Swiss manufacturer Zurich Instruments can demodulate the input signal in the frequency range from DC to 500 kHz (optionally up to 5 MHz).
The data is controlled and evaluated via the built-in data and web servers, which can be accessed from any mobile device with a web browser. The LabOne® user interface provides a clear presentation of all data.
This powerful yet intuitive user interface offers a wide range of functions for analysis in the time and frequency domains. LabOne® also supports the setup of control loops, the performance of noise measurements, and the interpretation of measurement data.
Appropriate interfaces are also provided for the most common programming languages.
