Description
Overview
The Keysight N4000A is an SNS Series noise source designed for accurately measuring devices with low noise figure or devices whose gain is sensitive to small changes in source impedance. Operating from 10 MHz to 18 GHz with nominal 6 dB Excess Noise Ratio (ENR), it maintains constant impedance whether on or off, reducing measurement errors that can mask as device noise.
Key Features
- Frequency range: 10 MHz to 18 GHz
- Nominal Excess Noise Ratio (ENR): 6 dB
- Electronic storage of ENR calibration data
- Automatic ENR data download to NFA analyzers
- Temperature compensation for improved measurement accuracy
- APC 3.5 mm connector standard (Type-N optional)
- Maintains constant impedance on and off
Applications
- Measuring devices with noise figures up to 20 dB
- Testing GaAs FETs and other mismatch-sensitive devices
- RF and microwave noise figure analysis
- Compatible with NFA, ESA-E, and X-Series analyzers
