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。

應用

• 材料科學：載流子遷移率、載流子密度、霍爾效應
• 輸運測量：電導測量，2和4端子電阻測量
• 吸收光譜
• 感測和執行MEMS：陀螺儀、諧振器、加速度計
• 量子感測和量子輸運：量子點和量子比特
• 磁性感測：SQUIDs, NV 色心, 原子磁強計，VSM
• 掃描顯微鏡：AFM、STM
• 噪聲表徵：噪聲密度，互相關測量

多設備同步
帶多台儀器同步功能，這樣就能在一台MFLI 界面中，操作多台MFLI：

• 用一個LabOne 軟體界面和API來操作所有的MFLI。
• 鎖定所有各台MFLI的相位、時鐘和振盪器。
• 同步時間戳和取樣率，以實現測量數據的同步。

一般規格

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.
