附加功能：
HP 4291A射频阻抗/材料分析仪为高精度，简便地测量表面安装组件和介电/磁性材料提供了完整的解决方案。HP 4291A使用直流电压测量技术，与反射测量技术相对，可在较宽的阻抗范围内进行更精确的阻抗测量。基本阻抗精度为±0.8％。高Q精度可实现低损耗成分分析。内部合成器以1 MHz的分辨率将频率从1 MHz扫描到1.8 GHz。1.8m无错误电缆将分析仪连接到测试站，因此您可以将测试点扩展到远离分析仪的位置，而不会降低精度。先进的校准和误差补偿功能消除了夹具中的测量误差因素，并确保了DUT / MUT的高精度和可重复性。
HP 4291A还通过使用IBASIC编程功能提供了自动的电平控制和测试信号监视功能；可以在恒定电压或恒定电流下测量设备。使用可选的直流偏置（最高40 V和100 mA）测量与偏置相关的阻抗特性。只需按一下按钮，内置的等效电路分析功能就会自动计算五个电路模型的电路常数值（类似于HP 419A的等效电路分析功能）。
HP 4291A具有两个测量通道。每个通道都可以设置为测量单个（例如2个）或双重（例如Z-theta）阻抗参数。带分屏显示的彩色CRT可以显示活动迹线和内存迹线（存储在RAM中）。内置软盘驱动器以LIF或MS-DOS格式存储程序和测试数据。
使用可选的IBASIC（选件1C2），您可以直接从HP 4291A控制外部测试设备，例如温度室或晶圆探测器。您不需要单独的仪器控制器。选件1C2为您提供了键盘和HP IBASIC编程语言，用于测试自动化和集成。
材料评估
HP 4291A可以轻松，复杂地进行材料评估，并提高材料评估的质量和效率。HP 4291A提供了宽频率范围（1 MHz至1.8 GHz）中的整体介电/磁性材料测量解决方案。
测试装置
从四种类型的组件测试装置中进行选择：HP 16191A，HP 16192A，HP 16193A和HP 16194A。这些测试夹具直接连接到测试站的APC-7连接器。每个夹具设计用于0.5毫米至20毫米的不同组件尺寸范围，并且可以处理不同类型的端接。这些可调夹具简化了设备连接。对于温度系数测试，HP 16194A高温组件测试夹具可在-55°至+ 200°C的温度烤箱中使用。
这些夹具与HP 4291A的内置补偿软件一起，可确保阻抗精度和测量重复性。HP 16453A介电材料测试夹具和HP 16454A磁性材料测试夹具提高了介电常数或磁导率测量的准确性和易用性。这些材料固定装置具有-55°至+ 200°C的宽工作温度。
Additional Features:
The HP 4291A RF impedance/material analyzer provides a total solution for high-accuracy and easy measurement of surface-mount components and dielectric/magnetic materials. The HP 4291A uses a direct current voltage measurement technique, opposing the reflection measurement technique, for more accurate impedance measurement over wide impedance range. Basic impedance accuracy is ±0.8%. High Q accuracy enables low-loss component analysis. An internal synthesizer sweeps frequency from 1 MHz to 1.8 GHz with 1 MHz resolution. A 1.8m error-less cable connects the analyzer to a test station so you can extend your test point away from the analyzer without losing accuracy. Advanced calibration and error compensation function eliminate measurement error factors in fixtures and assure high accuracy and repeatability at DUT/MUT.
The HP 4291A also provides automatic level control and monitor of test signals by using IBASIC programming function; devices can be measured under a constant voltage or current. Measure bias-dependent impedance characteristics with optional dc bias (up to 40 V and 100 mA). At the push of a button, the built-in Equivalent Circuit Analysis Function automatically calculates the circuit constant values of five circuit models (similar to HP 419A's Equivalent Circuit Analysis Function).
The HP 4291A has two measurement channels; each channel can be set to measure a single (e.g. 2) or dual (e.g. Z-theta) impedance parameter. The color CRT with split-display can show both active traces and memory traces (stored in RAM). A built-in floppy disk drive stores programs and test data in either LIF or MS-DOS format.
With optional IBASIC (Option 1C2), you can control external test equipment such as a temperature chamber or wafer prober directly from the HP 4291A. You do not need a separate instrument controller. Option 1C2 gives you a keyboard and the HP IBASIC programming language for test automation and integration.
Material Evaluation
The HP 4291A enables easy and sophisticated material evaluation and improves material evaluation quality and efficiency. The HP 4291A provides the total dielectric/magnetic material measurement solutions in wide frequency range (1 MHz to 1.8 GHz).
Test Fixtures
Select from four types of component test fixtures: HP 16191A, HP 16192A, HP 16193A, and HP 16194A. These test fixtures directly connect to the test station's APC-7 connector. Each fixture is designed for a different component size range, from 0.5 mm to 20 mm, and can handle different types of termination. These adjustable fixtures simplify device connection. For temperature coefficient testing, the HP 16194A high-temperature component test fixture can be used in a temperature oven from -55° to +200° C.
Together with the HP 4291A's built-in compensation software, the fixtures ensure impedance accuracy and measurement repeatability. The HP 16453A dielectric material test fixture and HP 16454A magnetic material test fixture improve the accuracy and ease of use for permittivity or permeability measurements. These material fixtures have wide operating temperature of-55° to +200° C.
