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.
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.
Amplifier, up converter and down converter measuring mode
With multiple measurements modes, 3986 series Noise Figure Analyzers can be used to test noise figure and gain measuring of DUT as well as support the measurement of automatic gain scanning and noise figure of multistage frequency reception links reception link. Intuitive user interface makes easy setting of various measurements.
Single sideband and double sideband measuring function
It has the capacity of setting, controlling and data processing for the measurement of single sideband (including upper sideband and lower sideband) and double sideband. During noise figure measurement, the setting of the sideband must be the same as that is actually applied by the measured subject.
Comprehensive loss compensation functions
Loss in the channel can be compensated by means of fixed or excel form before and after the measurement, which would greatly benefit precise measurement of noise figure of automatic test system or microwave chips.
Flexible document and excel processing functions
The types of documents and excels that can be processed by 3986 Series Noise Figure Analyzers include limit lines, excess noise ratio table, track lines, instrument status, frequency list, loss compensation table and screen images. For user data process purposes, documents and excels can be edited, saved, pulled and deleted.
Passed/failed test notification limit line function
Limit line function of test passed/failed notification simplifies passed/failed test for the use of production line. Types of limit lines include upper limits and lower limits. A pair of upper and lower limit lines could be set individually for each display channel. When measurement results exceed limit range, the instrument would prompt “Limit Line Failed” notification in red.
Various external interfaces
Various external interfaces enable high re-usability. Smart interfaces like GP-IB, LAN, USB and VGA can enable user function extension and reconstruction of the system.
Dual noise source drive
Standard and smart noise source drive interfaces provided. Standard noise source drive interface that provides +28 V pulse drive voltage to support noise sources from multiple manufacturers. It’s highly compatible. Smart noise source drive interface is also compatible with Keysight N4000 series smart noise sources. Noise figure analyzer can identify the connection of smart noise source and load excess noise ratio data automatically. It can also detect changes of environment temperature for temperature correction of noise figure to improve speed and accuracy of measurement.
TYPICAL APPLICATIONS
Basic amplifier measurement application
Basic amplifier measurement is the most common measurement mode. It’s used for noise figure and gain measurement of measured subjects without frequency conversion (including active or passive linear units or systems like amplifiers, filters, and isolators).
Down converter mode measurement application
Down converter mode of the system is focused on spread spectrum measurement of amplifier measured subjects. When the frequency range of an amplifier measured subject exceeds that of the noise figure analyzer, spread spectrum measurement of the noise figure is realized by external mixer. External mixer is used during calibration and measurement as a part of the test system. To reduce the uncertainty of noise figure measurement, frequency conversion loss and noise figure of the chosen mixer should be as small as possible. Besides, the intermediate frequency output interface of the mixer should be well isolated to local oscillation signals.
Up and down converter measurement application
The measured subject is an up and down converter installation, up converter and transmitter or down converter and receiver for instance, then the output intermediate frequency would be in the working frequency range of the noise figure analyzer. During up and down converter measurement, 3986 series Noise Analyzer provides two modes of settings, fixed intermediate frequency, variable local oscillation and fixed local oscillation, variable intermediate frequency, which are used for RF response characters and intermediate frequency response characters, respectively.
