The N4000A is a used 18 GHz Noise Generator from Agilent. A noise signal generator is a type of electronic test equipment that produces a noise, or random signal, to test an electronic product’s frequency response, noise figure, and other important parameters.
- Electronic storage of Excess Noise Ratio (ENR) calibration data decreases the opportunity for user error
- Automatic download of ENR data to the NFA speeds overall set-up time
- Temperature compensation improves measurement accuracy leading to tighter specification of device performance
The Agilent N4000A is a 10 MHz to 18 GHz noise source with nominal ENR 6 dB. The Agilent 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 Agilent N4000A noise sources has a choice of connectors, with an APC 3.5(mm) connector as standard.
