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 accurately measuring devices with low noise figure, or devices whose gain is especially sensitive to small changes in source impedance. DUT&＃39;s with noise figure up to 20 dB can be accurately and reliably measured with this device. The N4000A noise sources has a choice of connectors, with an APC 3.5(mm) connector as standard.
