3986 Series Noise Figure Analysers include 3986A (10 MHz～4 GHz), 3986D (10 MHz～18 GHz), 3986E (10 MHz～26.5 GHz), 3986F (10 MHz～40 GHz) and 3986H (10 MHz～50 GHz). Features of the product include wide-range frequency coverage, high-sensitivity reception, friendly user interface, dual channel HD display, various external interfaces, and dual noise source drive etc. It can measure the noise figure and gain of amplifiers, up converters and down converters, as well as to support automatic measuring of noise figure of multistage frequency reception links.

Guide interfaces are intuitive for setting measurement modes. Comprehensive loss compensation function can compensate loss induced in channels before and after measurement by means of fixed or excel forms. Internal noise figure measurement uncertainty calculator does quantitative analysis of the uncertainty of measuring noise figure. Limit line function that provides test passed/failed notification simplifies the determination of passed/failed test. User friendly features make it easy for engineering technicians to set measurements correctly, to observe and save measurement results in different forms. They can be broadly used in R&D, manufacturing, testing and technical assurance tests of electronic equipment for radar, communication, navigation etc.

High-sensitivity reception and high-precision test performance

The optimum reception sensitivity reaches up to -170 dBm/Hz, and full band reception sensitivity precedes-162 dBm/Hz. The breakthrough in automatic modulation and precise calibration technology of large scale channel gains in the whole instrument. Linearity within the range of noise power measurement precedes ±0.1 dB.reaches up to,

Chinese and English operation interface with dual-channel HD display

Chinese and English operation interface with 10.1-inch LCD monitor that can be displayed in three forms, i.e. diagrams, excels and tester display. In the form of diagram display, it can display the measurement results combination of two random parameters, such as noise figure, Y factor, gain, equivalent input noise temperature, changing with the frequency.
