描述

SNS 系列 N4000A 是一款 10 MHz 至 18 GHz 噪声源，额定 ENR 为 6 dB。N4000A 噪声源专为测量低噪声系数器件，或增益对信号源阻抗的微小变化非常敏感的器件而设计。利用该器件可可靠地测量噪声系数高达 20 dB 的被测件。N4000A 噪声源可选用多种连接器，标准配置是 APC 3.5 毫米（阳头）连接器。





描述 
The SNS series N4000A is a 10 MHz to 18 
GHz noise source with nominal ENR 6 dB. The N4000A noise source is designed for 
ac c urately measuring devices with low noise figure, 
or devices whose gain is especially sensitive to small changes in source 
impedance. DUT‘s with noise figure up to 20 dB can be ac c urately and reliably 
measured with this device. The N4000A noise sources has a choice of connectors, with an 
APC 3.5(mm) connector as standard.
