The 4191A RF Impedance Analyzer measure 14 parameters with a maximum resolution of 4.5 digits. The internal synthesizer provides variable frequencies from 1 MHz through 1000 MHz covering the UHF, VHF, and video bands with automatic sweep capability. An internal dc bias supply with auto sweep function covers the voltage range of ± 40 V in 10 mV steps.该4191A射频阻抗分析仪测量14个参数，以zui高分辨率为4.5位。内部合成器提供可变频率从1兆赫到1000兆赫覆盖超高频，甚高频和视频带自动扫描功能。内部直流偏置电源，自动扫描功能包括电压范围为± 40 V的10 mV的步长。

The HP 4191A permits reliable measurements over a wide measuring range. Its outstanding repeatability, frequency response, and accuracy are made possible by a unique error-correction capability and specially designed test fixtures. These features allow the HP 4191A to be used in evaluating electronic materials, components, and circuitry.惠普4191A许可证了可靠的测量测量范围宽。它杰出的重复性，频率响应，和准确性都成为可能的一个独特的纠错能力，以及专门设计的试验装置。这些功能使惠普4191A ，用于评估电子材料，组件和电路。

The internal synthesizer provides a maximum resolution of 100 Hz (option 002) with an accuracy of 3 ppm, allowing small changes in the resonant frequency of the device under test to be easily detected. The swept frequency capability aids in the analysis of frequency characteristics of the device.内部合成器提供了zui高分辨率为100赫兹（选项002 ） ，度为3含量，使小变化，共振频率的被测设备可以方便地检测。席卷频率的能力，艾滋病在分析频率特性该设备。

Two complete front-panel settings (parameter selection and the sweep control) can be stored in a non-volatile memory and recalled at any time with a single key operation. This, together with the standard HP-IB interface, makes the HP 4191A extremely efficient as either a standalone or a systems instrument.两个完整的前面板设置（参数选择和扫描控制）可以储存在非挥发性记忆体，并回顾在任何时候用一个关键作业。加上标准HP - IB接口界面，使惠普4191A其效率作为一个的或系统的工具。

These unique features permit very wide applications in : (1) semi-conductor testing such as surface state evaluation at high frequencies (CV/GV and conductance (G/ww) characteristics), and the input/output impedance evaluation of diodes and transistors, (2) resonator, filter, and magnetic and dielectric materials testing, (3) evaluation of LCR components such as high-frequency chip and leaded components, and (4) testing of communications-related components such as cables, connectors, etc.这些独特的功能允许非常广泛的应用： （ 1 ）半导体测试，如表面状态评估在高频率（简历/货车和电导（克/湿重）的特点） ，以及输入/输出阻抗评价二管和晶体管， （ 2 ）谐振器，过滤器，磁性和电介质材料的测试， （ 3 ）评价比率部件，如高频率芯片和含铅成分，和（ 4 ）测试的通信有关的部件，如电缆，连接器，等
