Product Overview

KEYSIGHT N4000A

The Keysight N4000A is a 10 MHz to 18 GHz noise source with nominal ENR 6 dB. The Keysight N4000A noise source was 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.

Features and specificiatons of the Keysight N4000A Noise Source include:

• ENR is nominally 6 dB from 10 MHz to 18 GHz
• DUTs with noise figures up to 20 dB can be accurately and reliably measured
• 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
• 3.5mm connector ships standard, optional Type-N connector is available as Option 001
