產品介紹∣500 kHz / 5 MHz 鎖相放大器

簡介
瑞士蘇黎世儀器(Zurich Instruments) 的MFLI 是一款數位鎖相放大器，為中頻和低頻範圍的測量設定了新標杆。MFLI 提供兩種版本，適用於「直流至500 kHz」（可在有需要時升級到5MHz）和「直流至5 MHz」的頻率範圍。憑藉精心開發的模擬和數位前端，結合FPGA，使得儀器具有高速數位信號處理功能。MFLI 將優越的性能與出色的LabOne軟體包融合到了一起。內建的數據服務器和網路服務器可直接連接至任何能夠運行網路瀏覽器的設備。

Introduction
The Zurich Instruments MFLI is a digital lock-in amplifier that covers the frequency range from DC to 500 kHz (and up to 5 MHz when upgraded). Thanks to its embedded data and web servers, the MFLI can be used directly with any device running a web browser without further software installations. With its carefully developed analog and digital front ends and the fast digital processing afforded by the on-board FPGA, the MFLI combines its excellent performance with the LabOne user interface.

Applications

Materials science: carrier mobility, carrier density, Hall effect
Transport measurements: conductance measurements, 2- and 4-terminal resistors
Absorption spectroscopy
Sensing and actuation (MEMS): gyroscopes, resonators, accelerometers
Quantum sensing and transport: quantum dots, qubits
Magnetic sensing: SQUIDs, NV centers, atomic magnetometry, VSM
Scanning microscopy: AFM, STM
Noise characterization: noise density, cross-correlation measurements

Multi-Device Synchronization
With multi-device synchronization (MDS) it is possible to operate multiple MFLIs as a single multi-channel device:

Operate all instruments from a single LabOne user interface and LabOne API.
Lock in phase all instrument clocks and oscillators (stable phase relationship).
Synchronize time stamps and sampling rates for automatic alignment of measurement data.
