========== 135 9027==0072
HP/Agilent 346A Noise Source, 10 MHz to 18 GHz, nominal ENR 6 dB
Description
The HP/Agilent 346A noise source is the ideal companion to Agilent's noise figure solutions. Since it is broadband (10 MHz to 18 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source reduces a major source of measurement uncertainty; reflections of test signals. The very small change in reflection coefficient (<0.01) from ON to OFF is designed especially for accurate characterization of input-impedance-sensitive devices (like GaAsFETs and many UHF amplifiers).

Agilent 346系列噪声源是与Agilent噪声系数测试仪和系统联用的理想噪声信号源。因为它们都具有宽频带(10MHz至18GHz或26.5GHz)特性,故不再需要若干个不同频带的信号源。每个噪声源各自具有特定频率下的校准ENR值,为便于对8970B加载,校准值打印在它的商标上。每个噪声源的低驻波比(SWR)使测量中的主要不确定性因素-测试信号的反身地以减小。此外,备有的各种连接器也减少了对可能导致精度降低的接头适配器的需求。
Agilent346系列噪声是为广泛的测量应用而设计的。346C的频率覆盖范围最宽,为10MHz到26.5GHz,346B具有高的ENR,低的SWR和各种型式的接头,使之成为一种通用的噪声源。346A是专为精确表征输入阻抗灵敏器件(如GaAs FET和许多UHF放大器)而设计的。该仪器从接通至切断期间反射系数的变化极小器)而设计的。该仪器从接通至切断期间反射系数的变化级小(<.01),因而在测量噪声系数和增益的随输入阻抗变化的关系时可使误差最小。
