Keysight Technologies - N8976B
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.

Keysight Technologies N8976B Spec Sheet
Content is AI-generated. Verify critical details with manufacturer-provided resources.
What frequency range does the Keysight N8976B noise figure analyzer cover?
The N8976B NFA X-Series noise figure analyzer covers 10 MHz to 40.0 GHz. It is a multi-touch analyzer that combines noise figure measurement capabilities with full-featured spectrum analyzer and IQ analyzer (basic) modes. When operating in spectrum analyzer or IQ analyzer mode, the instrument is specified to 44 GHz, providing additional measurement flexibility beyond dedicated noise figure analysis.
What is the displayed average noise level (DANL) of the N8976B?
The N8976B achieves excellent DANL performance ranging from -164 dBm (specification) at 10 MHz to 1.2 GHz, to -153 dBm at 39.9 GHz to 40.0 GHz, measured with preamp on, input terminated, and 10 Hz IF bandwidth. Typical DANL is even better, reaching -165 dBm at low frequencies. This low noise floor enables sensitive measurements of low-noise amplifiers and other high-performance RF components.
What noise sources are compatible with the N8976B?
The N8976B works with Keysight N400xA Series smart noise sources and 346 Series noise sources. It supports noise source ENR ranges from 4 to 6.5 dB (0 to 20 dB measurement range), 12 to 17 dB (0 to 30 dB measurement range), and 20 to 22 dB (0 to 35 dB measurement range). The instrument ships with a 346CK40 noise source, which provides superior match performance above 26 GHz for improved measurement uncertainty.
Does the N8976B include an internal preamplifier?
Yes, the N8976B includes an internal preamplifier that improves measurement sensitivity. The nominal internal preamp noise figure is 8 dB + (0.001112 × frequency in MHz) from 100 kHz to 3.6 GHz, 9 dB nominal from 3.6 to 8.4 GHz, and 10 dB nominal from 8.4 to 13.6 GHz. For even better performance, the instrument supports optional external U7227 Series USB preamplifiers that provide enhanced low-noise performance and additional gain.
What DUT profiles does the N8976B support?
The N8976B supports multiple DUT profiles including amplifiers and any non-frequency-converting devices such as attenuators and filters. It also supports downconverting DUTs with fixed or variable IF, upconverting DUTs with fixed or variable IF, and system downconverters that use external mixers as part of the measurement system. The instrument can control external local oscillators via GPIB, LAN, or USB for mixer and converter measurements.
What is the measurement bandwidth range of the N8976B?
The N8976B offers measurement bandwidth from 1 Hz to 3 MHz in E24 series increments (1 Hz, 1.2 Hz, 1.5 Hz, etc.), plus additional fixed bandwidths of 4 MHz, 5 MHz, 6 MHz, and 8 MHz. When operating in IQ analyzer (basic) mode, the analysis bandwidth extends up to 25 MHz. This wide range of measurement bandwidths allows optimization for different noise figure measurement scenarios and trade-offs between speed and accuracy.
What connector type does the N8976B use?
The N8976B uses a 2.4 mm male connector for the RF input, providing operation to 40 GHz and beyond (44 GHz in spectrum analyzer mode). The 2.4 mm connector offers excellent performance and durability for millimeter-wave measurements. Input VSWR is nominally 1.2:1 from 10 MHz to 3.6 GHz, 1.5:1 from 3.6 to 26.5 GHz, and less than 1.8:1 from 26.5 to 44.0 GHz.
What display and output formats are available on the N8976B?
The N8976B features a 10.6-inch diagonal multi-touch display with 1280 × 768 WXGA resolution and supports two measurement channels simultaneously. Results can be displayed in graphical format, table of values, or meter mode. It provides four markers per channel and supports upper and lower limit lines for each channel. Measurement results include noise figure (F in dB or as ratio), gain (G in dB), Y-factor, effective noise temperature in Kelvin, and relative power density (P hot and P cold) in dB.
