Product Overview

The 3986 series Noise Figure Analyzers include models 3986A (10MHz to 4GHz), 3986D (10MHz to 18GHz), 3986E (10MHz to 26.5GHz), 3986F (10MHz to 40GHz), and 3986H (10MHz to 50GHz), offering wide frequency coverage, flexible band selection, high receiver sensitivity, user-friendly interface, large-screen dual-channel HD display, rich peripheral interfaces, and dual noise source drivers. They can measure the noise figure and gain of amplifiers, upconverters, and downconverters, and support the automatic measurement of noise figure in multi-stage frequency conversion receiver chains. They feature an intuitive measurement mode setup guide interface, multiple input interaction methods, and simplified mode settings. They also have comprehensive loss compensation capabilities, allowing for fixed or tabular compensation of losses introduced by the measurement channels before and after the test item. An integrated noise figure uncertainty calculator enables quantitative analysis of noise figure measurement uncertainty. The test pass/fail notification limit line function simplifies the determination of pass/fail tests. Their user-friendly features make it easy for engineers to correctly set up measurements, view and save results in different formats. The products are widely used in scientific research, production, testing, and technical support for communication, navigation, and other electronic equipment.
