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'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.
