3986 Series Noise Figure Analyzers

Wide frequency coverage

The coaxial integrated frequency of 3986 series Noise Figure Analyzers covers the range of 10 MHz~ 50 GHz, where 5 frequency range configurations are selectable for different user’s test demand of different band. With external MMW extended frequency modules, the noise figure measurement frequency range can be extended to 110GHz.

High-sensitivity reception and high-precision measurement performance

The optimum reception sensitivity precedes -170 dBm/Hz, and the full-band reception sensitivity precedes -162 dBm/Hz. It adopts automatic adjustment and precise calibration technologies, which improve the channel gain. And the linearity within the range of noise power measurement precedes ±0.1 dB.

Chinese and English operation interface with big screen dual-channel HD display

Chinese and English operation interface with 10.1 inch big screen LCD monitor that can display in three formats, i.e. graphs, tables and meter display. In the form of graph display, it can display in combination the measurement results of two arbitrary parameters which change along with frequency, such as noise figure, Y factor, gain, and equivalent input noise temperature.

Amplifier, up converter and down converter measurement mode

Basic amplifier measurement mode is used for noise figure and gain measurement of the device under test, which falls in the amplifier category within the frequency range of the Noise Figure Analyzers. The extended frequency range measurement in the down converter mode is used for noise figure and gain measurement of amplifier, of which the frequency exceeds the frequency range of the Noise Figure Analyzers.

They have noise figure and gain measurement functions of up converters and down converters, as well as to support automatic scanning measurement of noise figure of multi-stage converters.

Interface setting in measurement mode is intuitive. All measurement settings corresponding to measurement mode can be done in the same test interface.

Single sideband and double sideband measurement 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 sideband setting must be the same as that is actually applied of the device under test.

Comprehensive loss compensation functions

Loss in the measurement channel can be compensated by means of fixed or table form before and/or after the measurement, which would greatly benefit precise measurement of noise figure of automatic test system or microwave chips.

Flexible file and table processing functions

The types of files and tables that can be processed by 3986 Series Noise Figure Analyzers include limit lines, excess noise ratio table, trace file, state file, frequency list, loss compensation table and screen images. For user data process purposes, files and tables can be edited, saved, loaded, 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 test 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. Noise Figure Analyzers 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

Basic amplifier measurement is the most common measurement mode. It’s used for noise figure and gain measurement of the device under tests without frequency conversion (including active or passive linear units or systems like amplifiers, filters, and isolators) .

Measurement Setup

System down converter measurement mode

The down converter mode focuses on extended frequency range measurement of amplifier. When the frequency range of an amplifier exceeds that of the Noise Figure Analyzers, extended frequency range measurement of the noise figure is realized by an 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 port of the mixer should be well isolated to local oscillation signals.

Measurement Setup

Up/down converter measurement

The device under test is an up/down converter installation, up converter and transmitter or down converter and receiver for instance, then the output intermediate frequency would be in the frequency range of the Noise Figure Analyzers. During up/down converter measurement, 3986 series Noise Figure Analyzers provide two modes of settings, fixed intermediate frequency, variable local oscillation and fixed local oscillation, variable intermediate frequency, which are used for measuring the RF response characters and intermediate frequency response characters of the device under test, respectively.
