The MFLI lock-in amplifier from Zurich Instruments – precision, flexibility, and web control
A lock-in amplifier is an essential instrument when it comes to measuring very weak signals in noisy environments with high precision. Phase-sensitive detection and digital signal processing allow signal components to be extracted that would otherwise remain invisible.
The MFLI combines this proven methodology with modern features that make it particularly flexible, powerful, and user-friendly:
- Integrated data and web server: Operation is carried out directly via a web browser, without the need for local software installation.
- Combined analog and digital front end for high measurement quality with low noise.
- Optional extension from 500 kHz to 5 MHz – you choose the frequency range that meets your application requirements.
- Upgrades and options are also available, such as a multi-demodulator, modulation option, impedance measurement, and much more.
The MFLI is ideal for a wide range of applications in research and development, e.g.:
- Optical experiments with choppers or pulsed sources – ideal when signal modulation is used.
- Impedance measurements (in combination with sweeper function).
- Sensor measurements, nanotechnology, MEMS, electronics test setups.
- Time-resolved measurements with very low noise.
- Due to its flexible software tools (LabOne®), the MFLI combines several functions such as oscilloscope, spectrum analysis, sweeper, and signal generator in one platform, which saves hardware and significantly simplifies the test setup.
Another advantage: web-based control enables platform-independent use—from PCs to Macs to tablets—and facilitates remote control and automation..
