主要特點
簡介
瑞士蘇黎世儀器公司的SHFLI將鎖相放大器這類產品的功能與優勢(雜訊抑制、相位靈敏度、頻率追蹤等)延伸到工作頻率高達8.5 GHz的應用。
SHFLI 包含兩個可獨立使用的鎖相放大器物理通道。 每個通道均配備 4 個支援並行多頻率分析的雙相解數據器,以及一個用於生成驅動和參考信號的 6 GSa/s 信號產生器。 解調器中低通濾波器參數可自由調整,可以在雜訊抑制和測量速度之間達到最優平衡。 USB 和千兆乙太網數位介面能夠以高達 4 MSa/s 的速度將數據連續傳輸到電腦,而 4 個高速輔助輸出埠和 4 個高精度輔助輸出埠可將測量結果轉換為類比信號輸出,並添加自定義的縮放和偏置,方便與其他儀器集成使用。
SHFLI 包括 LabOne® 控制軟體,藉助其圖形使用者介面,可以輕鬆方便地進行設置。 通過該軟體,使用者可以對包括鎖相放大器、具備快速傅里葉轉換 (FFT) 的雙通道示波器、參數掃描器和頻譜分析儀等在內的整個測量工具集進行全方位控制。 此外,所有功能和數據擷取都可以通過常用程式設計語言來進行二次開發,支援 LabVIEWTM、MATLAB®、C、. NET 和 Python。
SHFLI 具備低輸入雜訊、寬分析頻寬和超短時間常數等特點,是一款理想的測量工具,適用於要求最嚴苛的微波應用。

Introduction
The Zurich Instruments SHFLI Lock-in Amplifier brings the advantages of lock-in amplifiers – noise rejection, phase sensitivity, frequency tracking and more – to applications that operate at frequencies up to 8.5 GHz.
The SHFLI contains two physical channels that operate as independent lock-in amplifiers. Each one is equipped with 4 dual-phase demodulators that enable parallel multi-frequency analysis and with a 6 GSa/s signal generator for drive and reference signals. The demodulator filters can be tuned to give the best tradeoff between noise rejection and measurement speed. The USB and gigabit ethernet digital interfaces enable continuous data transfer to the computer at up to 4 MSa/s while the 4 high-speed and 4 high-precision auxiliary outputs can convert the measurement results, with custom scaling and offset, into analog signals for integration with other instruments.
Trailblazers. The GHFLI and SHFLI Microwave Lock-in Amplifiers.
The SHFLI includes the LabOne® control software that makes setting it up easy and convenient thanks to its graphical user interface. It also provides firm control over the entire measurement toolset that comprises the lock-ins, a dual-channel oscilloscope with FFT, a parametric sweeper, a spectrum analyzer and much more. Additionally, all the functionality and data acquisition can be accessed through the major programming languages for ease of integration: LabVIEWTM, MATLAB®, C, .NET and Python are supported.
The SHFLI’s low input noise, its wide measurement window and its very fast time constant make it the ideal measurement tool even for the most demanding microwave applications.
Applications
The SHFLI can serve even the most demanding applications that require measurement and tracking of periodic signals, and device characterization and control up to 8.5 GHz.
