Keysight Agilent N8976B 40GHz Noise Figure Analyzer w/ Options

Keysight Agilent N8976B 10MHz to 40GHz Noise Figure Analyzer, Multi-touch

The N8976B high performance noise figure analyzer is designed to make fast, accurate and repeatable noise figure measurements. When paired with an SNS Series noise source and U7227 Series USB preamplifier the ENR data from the SNS and USB preamplifier data automatically downloads into the N8976B.

The N8976B has a multi-touch interface that allows stretch, pinch, and drag gestures. Most menus can be accessed with the tap of a finger without changing screens.

Noise source calibrations for Y-Factor measurements have been streamlined by allowing combined calibrations for up to 12 DUT setups in a single step. Saving valuable test time can be achieved for many types of DUT’s by using the internal calibration feature, which does not require a user calibration to be performed.

A built-in noise figure uncertainty calculator can pre-populate data from the SNS noise source, USB preamplifier, as well as all the required instrument parameters such as analyzer noise figure, gain and noise figure uncertainty, and match. Default noise figure settings offer simultaneous noise figure and gain measurements. By using Table view several measurements including Noise Figure, Noise Factor, Y-Factor, Gain, Phot, Pcold, and Teffective can be viewed simultaneously in tabular form.

The N8976B has additional flexibility with spectrum analyzer and IQ Analyzer (Basic) modes that allows customers to move beyond noise figure to further analyze DUT characteristics if needed.

A 44 GHz internal Preamplifier (Option P44), 25 MHz analysis bandwidth (Option B25), precision frequency reference (Option PFR), fine step attenuator (Option FSA), and noise floor extensions (Option NFE) are included as standard options.

An external simulated LO to the input of a frequency translating device can be achieved by connecting to a Keysight signal generator over LAN, USB, or GPIB. LO control is adjusted from the N8973B.

Note: The NFA X-Series noise figure analyzer is more than a dedicated noise figure analyzer. Each model has full featured spectrum analyzer and IQ analyzer (basic) modes. The analyzer is specified to 44 GHz when in SA or IQ analyzer mode

High performance Noise Figure Measurement

The noise figure analyzer represents a dedicated version of noise figure measurement solutions. A noise figure analyzer in its most basic form consists of a receiver with an accurate power detector and a circuit to power the noise source. The high performance Keysight NFA X-Series noise figure analyzers have variable bandwidths to facilitate measurement of narrow-band devices, as do spectrum analyzer-based measurement systems.

Optimize for noise figure using the NFA Series of high performance noise figure analyzers, which are designed to make fast, accurate, repeatable measurements. Key features include the simple user interface, graphical display, data storage, selectable bandwidths and on screen limit lines for pass/fail testing. With the NFA Series reliable measurements up to 40 GHz are now available in a single instrument.

Easy Noise Figure Measurement Setup

The NFA series of Noise Figure Analyzers now takes the pain out of complex measurement setups, with their simple but instructive menus. The built-in help button gives key function and remote programming commands, that should eliminate the need to carry manuals when setting up measurements.

Low Noise Figure Measuring Instrumentation Uncertainty

When making noise figure measurements, a key parameter to be aware of is measurement uncertainty. The NFA has a low instrumentation uncertainty to aid in accurate and repeatable measurement of manufacturers’ components.

Increase Measurement Throughput

In manufacturing environments, fast measurement speed and repeatability are critical. The NFA series of Noise Figure Analyzers now include many features that can reduce your measurement time and increase throughput. The frequency list function allows you to select specific points within a complete measurement span to make your measurement. The Sweep averaging function allows a real-time update to the screen during a measurement, as you adjust the performance of the DUT during a sweep.
