MFLI Lock-in Amplifier
The Zurich Instruments MFLI is a digital lock-in amplifier that sets the new standard for measurements in the medium and low frequency range. The MFLI is available in two versions covering the frequency range DC to 500 kHz and DC to 5 MHz (an upgrade from 500 kHz to 5 MHz is possible later). With the carefully developed analog and digital front ends in combination with the merits of fast digital processing provided by the on board FPGA, the MFLI combines superior performance with the outstanding LabOne® toolset. The embedded data and web servers allow straightforward connection to any device running a web browser.

MFLI Available Options
MFLI 5 MHz Lock-in Amplifier
The 5 MHz version of the instrument is offered as a bundle containing the MFLI 500 kHz plus the MF-F5M Frequency Extension with a more attractive price than buying the items separately. Please note that the special pricing is offered only when the two items are purchased with a single purchase order referring to a single quotation.
MF-F5M Frequency Extension
This option extends the frequency of 500 kHz MFLI lock-in amplifiers and 500 kHz MFIA impedance analyzers to the frequency range of DC to 5 MHz. The upgrade is enabled on the instrument by a software key and does not require any hardware changes or return of the instrument. Also, the installation can be carried out at any later point in time. The upgrade is independent of the option set installed and does not affect any of the other instrument specifications, only the available frequency range for the oscillators.
MF-IA Impedance Analyzer Option
The Zurich Instruments MF-IA is an upgrade option for the MFLI lock-in amplifier. It provides the full digital impedance analyzer and precision LCR meter functionality that sets the new standard for impedance measurements in the frequency range from DC to 500 kHz / 5 MHz. With the MF-IA option installed impedance can be measured with 0.05% basic accuracy and a measurement range spanning from 1 mΩ to 1 TΩ. The instrument has a high measurement repeatability and a small temperature drift.
MF-PID Quad PID/PLL Controller
The MF-PID option consists of 4 configurable PID (proportional - integral - derivative) controllers. These controllers take a variety of different measurement data as the input quantity and they can provide fast feedback to a number of instrument parameters or analog output channels. Seamlessly integrated with the lock-in amplifier, the programmable PIDs enable operation in a wide range of applications such as the setup of phase-locked loops (PLLs) for the phase synchronization of two lasers, CEO stabilization and advanced AFM modes.
MF-MD Multi-demodulator
The multi-demodulator option extends the capabilities of your MFLI or MFIA by
extending the number of demodulators to a total of 4
extending the number of oscillators to a total of 4
1 additional external reference PLL, making a total of 2
Simultaneous DC offset and AC signal measurement
MF-MOD AM/FM Modulation
The AM/FM modulation option allows generation of phase-coherent linear combinations of up to 3 oscillator frequencies. The direct measurement of (higher-order) sidebands in a variety of different modulation schemes, including amplitude modulation (AM) and frequency modulation (FM), can be conveniently set up in the LabOne® user interface. Unlike conventional double demodulation schemes, e.g.
MF-DIG Digitizer
The combination of the MFLI Lock-in Amplifier or MFIA Impedance Analyzer and having a Digitizer in a single box offers a wide range of measurement opportunities utilizing continuous streaming, cross-domain triggering and a segmented memory. The 2 Scope channels can display signals from the differential voltage input and the current input concurrently.
