該系統具有高性能的頻域介電 ( 介電質 )、電導、電化學、阻抗和增益相位測量功能。它是Novocontrol最新、最強大、最靈活的系統，推薦用於新儀器設計。

本系統採用模組化設計，以 Alpha-A 主機為基礎，通常與一個或多個針對特殊功能進行最佳化的測試介面結合。所有用於阻抗測量的測試介面都具有很高的通用性能，如最高的精度和超寬的阻抗和頻率範圍。

這使得Alpha-A 系統成為一款獨特且易於使用的儀器，其卓越的綜合性能可滿足許多特殊要求，例如4 電極高阻抗、高電壓、大電流測量以及用於電化學阻抗譜（Electrochemical Impedance Spectroscopy,簡稱EIS）的恒電位 / 恒電流功能。

Alpha-A 系列涵蓋 18 個數量級的阻抗範圍（每個阻抗測試介面 16 個數量級）、12.5 個數量級的頻率範圍和 2m° 的基本相位精度。

這種組合使 Alpha-A 系統成為一個強大的工具，為電頻域分析儀器開創了先河。因此，幾乎所有材料或元件（包括特殊功能）的介電常數、電導率和阻抗都可以在寬頻和寬溫度範圍內進行測量，而無需改變樣品幾何形狀或樣品治具。

作為 Alpha-A 系列的前身，Alpha 和 Beta 單機分析儀也具有 Alpha-A 系統的子系統功能，目前仍可作為經濟實惠的替代產品。有關三個分析儀系列的詳細比較，請點擊此處。

This system features high performance dielectric, conductivity, electrochemical, impedance and gain phase measurements in the frequency domain. It is our latest, most powerful and flexible system and recommend for new instrument designs.

The system is modular and based on an Alpha-A mainframe unit which usually is combined with one or more test interfaces optimized for special functionality. All test interfaces for impedance measurement offer in addition high general purpose performance like highest accuracy and ultra wide impedance and frequency range.

This makes the Alpha-A system an unique and easy to use instrument with exceptional overall performance which suits in addition many special requirements like e.g. 4 electrode high impedance, high voltage, high current measurements and potentiostat, galvanostat functions for electrochemical impedance spectroscopy EIS.

The Alpha-A family covers 18 orders of magnitude impedance range (16 orders for each impedance test interface), 12.5 orders of magnitude frequency range and 2m° basic phase accuracy.

This combination makes the Alpha-A system a powerful tool which sets the pace for electric frequency domain analysis instrumentation. As a result, permittivity, conductivity and impedance of nearly all materials or components including special functions can be measured broadband and over a wide temperature range without changing sample geometry or sample cells.

A sub range of the Alpha-A system functionality is also available by the Alpha and Beta single unit analyzers which are predecessors of the Alpha-A series and are still available as an economical alternative. A more detailed comparison of the three Analyzer series can be found here.
