Widely available for research and development, manufacturing, testing, and technical assurance testing of electronic devices such as radar, communication, and navigation.

The 3986 series noise figure analyzers include the 3986A, 3986D, 3986E, 3986F, and 3986H. Features of this product include a wide frequency range, high sensitivity reception, an easy-to-use user interface, dual-channel HD display, various external interfaces, and dual noise source drives. It supports automatic measurement of noise figures for amplifiers, upconverters, downconverters, and multi-stage frequency receiving links. The guide interface is intuitive for setting measurement modes. The comprehensive loss compensation feature can compensate for losses occurring in channels before and after measurements using fixed format or Excel format. The internal noise figure measurement uncertainty calculator performs quantitative analysis of the uncertainty in noise figure measurements. The limit line function, which provides pass/fail notifications for tests, simplifies the decision-making process for pass/fail tests. User-friendly features make it easy for engineering technicians to correctly set measurement values and observe and save measurement results in various formats.

Applications/Examples of results

It can be widely used in the research and development, manufacturing, testing, and technical assurance testing of electronic devices such as radar, communication, and navigation. Basic amplifier measurements are the most common measurement mode, which is used for measuring the noise figure and gain of the measurement target without frequency conversion (including active or passive linear units or amplifiers, filters, isolators, and other systems).

Detailed information

A Chinese and English operating interface with a dual-channel HD display. It features a 10.1-inch LCD monitor that can display in three formats: diagram, Excel, and tester display. In diagram display format, it can show measurement results of two random parameters that vary according to noise figure, Y factor, gain, equivalent input noise temperature, and frequency.
[Amplifier, Upconverter, Downconverter Measurement Mode] Using the 3986 series noise figure analyzer with multiple measurement modes, you can not only test the noise figure of the DUT but also support automatic gain scanning and noise figure measurement of multi-stage frequency receiving links. The intuitive user interface allows for easy configuration of various measurements.
【Pass/Fail Test Notification Limit Line Function】 The limit line function for pass/fail test notifications simplifies the pass/fail testing related to the use of production lines. There are two types of limit lines: upper limit and lower limit. Pairs of upper and lower limit lines can be set individually for each display channel. If the measurement results exceed the limit range, the measuring device will prompt a "Limit Line Failure" notification in red.
Various external interfaces enable high reusability. Smart interfaces such as GP-IB, LAN, USB, and VGA allow for the expansion of user functions and the reconstruction of systems.
【Dual Noise Source Drive】 Standard and smart noise source live interfaces are provided. A standard noise source drive interface offers a +28V pulse drive voltage to support noise sources from multiple manufacturers. It is highly compatible. The smart noise source drive interface is also compatible with the Keysight N4000 series smart noise sources. The noise figure analyzer can identify the connection of the smart noise source and automatically load excess noise ratio data. Additionally, it can detect changes in environmental temperature for temperature compensation of noise figure, improving the speed and accuracy of measurements.
【Downconverter Mode Measurement Application】 The system's downconverter mode focuses on the spectrum spreading measurement of the amplifier under test. When the frequency range of the amplifier under test exceeds the frequency range of the noise figure analyzer, the spectrum spreading measurement of the noise figure is achieved using an external mixer. The external mixer is used as part of the test system during calibration and measurement. To reduce the uncertainty of the noise figure measurement, the frequency conversion loss and noise figure of the selected mixer must be kept as low as possible. Additionally, the intermediate frequency output interface of the mixer must be sufficiently isolated from the local oscillator signal.
