The SNS series N4000A noise source is designed for accurately measuring devices with low noise figure, with a frequency range of 10 MHz to 18 GHz and nominal ENR 6 dB
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.

Model | Description |
N4000A (for Low Noise Figure or Mismatch Sensitive Devices Up to 18 GHz) | The N4000A is designed to accurately measure devices with low noise figure, or devices whose gain is especially sensitive to small changes in source impedance. This includes most GaAs FET’s. The N4000A maintains the same impedance whether turned on or off. By maintaining the same impedance at the input to the device under test (DUT) gain changes are reduced. These gain changes can often masquerade as DUT noise and cause noise figure measurement errors. The ENR of this noise source is nominally 6 dB from 10 MHz to 18 GHz. DUTs with noise figures up to 20 dB can be accurately and reliably measured with this device. The N4000A noise source has a choice of connectors, with an APC 3.5 (m) as standard. |
(for General Purpose Measurements from 10 MHz to 18 GHz) | The N4001A noise source is ideal for general purpose use with a low reflection coefficient and a nominal ENR of 15 dB from 10 MHz to 18 GHz. DUT’s with noise figures up to 30 dB can be measured accurately and reliably with this device. The N4001A has a selection of connectors, with an APC 3.5 (m) as standard. |
(for Measurements Up to 26.5 GHz) | The N4002A noise source was designed to measure DUT noise figures reliably and accurately up to 30 dB from 10 MHz up to 26.5 GHz accurately and reliably. This noise source comes with an APC 3.5 connector as standard. |
