Agilent 346A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小。
选件
Agilent 346B选件H01高ENR噪声源
Agilent 346B选件H01有高的ENR（典型值为21dB ）适于测量噪声系数很大的器件。
Agilent 346B选件H42 DBS噪声源
346B选件H42是专门研制用来测试直播卫星（DBS），中所用的低噪声单元变换器（LNB）。WR75波导输出，5dB ENR，
低的ENR校准不确定度和小驻波比改善了DBS LNB的噪声系测量精度。
Agilent 346C选件K01宽带噪声源
这类同轴噪声源利用2.4mm同轴接头覆盖1~50GHz频率范围。超噪比（ENR）额定在1GHz上为20dB，在50GHz上为7dB.
Certificate number
The Agilent 346A series noise source is an ideal noise signal source used in conjunction
with the Agilent noise coefficient tester and the system. Because they all have broadband.
(10MHz to 18GHz
or 26.5GHz) characteristics, it is no longer required for several different frequency bands.
Each noise source has its own specific frequency.
Calibrate the ENR value. For easy loading of 8970B, the
calibration value is printed on its trademark. The low stationed Bobbi (SWR) of each noise source makes the
main measurement.
Uncertainty factors - the reflexivity of test signals is reduced.
In addition, various connectors have also reduced the adaption of joints that may lead to reduced accuracy.
Device requirements.
The Agilent346 series noise is designed for a wide range of measurement applications.
The frequency coverage of 346C is wide, from 10MHz to 26.5GHz, 346B is high.
ENR, low SWR and various types
of joints make it a universal noise source. 346A is specially designed for characterizing input impedance
sensitive devices (such as GaAs).
FET and many UHF amplifiers. The instrument is designed from the smallest
device that changes the reflection coefficient during the cut-off period. The instrument is connected.
The variation order of the reflection coefficient is small (<.01) during the cut-off period, so the error is
small when measuring the relationship between the noise coefficient and the gain with the variation of the input
impedance.
Selection
Agilent 346B option H01 high ENR noise source
The Agilent 346B option H01 has a high ENR
(typical value of 21dB), which is suitable for measuring devices with large noise figure.
Agilent 346B option H42 DBS noise source
346B Option H42 is specially developed for testing low noise unit converter
(LNB) used in DBS. WR75 waveguide output, 5dB ENR,
Low ENR calibration uncertainty and small standing Bobbi improved
the accuracy of noise measurement of DBS LNB.
Agilent 346C option K01 broadband noise source
The coaxial noise source
uses the 2.4mm coaxial connector to cover the 1~50GHz frequency range. The ENR is rated at 20dB on 1GHz and 7dB. on 50GHz.
