The Keysight E4727A Advanced Low-Frequency Noise Analyzer is a modular PXIe-based system for precise characterization of low-frequency noise in semiconductor devices, components, and integrated circuits. It measures 1/f (flicker) noise, random telegraph noise (RTN), and burst noise across frequencies from 0.03 Hz to 10 MHz or 40 MHz with noise sensitivity to −183 dBV²/Hz. The system supports on-wafer and discrete device measurements of BJTs, FETs, diodes, resistors, and multi-terminal circuits, with options for 3-, 4-, 5-, or 6-terminal device configurations. It integrates with Keysight WaferPro Express software for automated test sequencing, wafer mapping, and data analysis.
