Make noise figure measurements with precision and speed

Keysight NF7-class noise figure analyzers include the N8679B-N8973B noise figure analyzers. They are designed to make fast, accurate, and repeatable noise figure measurements. When combined with our signal noise source (SNS) and the included USB preamplifier, the noise figure analyzer automatically downloads excess noise ratio (ENR) data, streamlining the measurement process. Our noise figure analyzers are easy to use with a multi-touch interface that enables stretch, pinch, and drag gestures. Choose one of our popular configurations or configure one specific to your application. Need help selecting?

Low instrument uncertainty

Designed to minimize internal circuitry errors, the low instrument uncertainty of ±0.02 dB ensures accurate, repeatable noise figure measurements.

Automated calibration

Streamlines Y-factor measurements by enabling automated calibration of up to 12 device-under-test (DUT) setups in a single step, significantly reducing test time.

Multimode signal analysis

Provides additional modes such as spectrum analyzer and IQ analyzer, enabling diverse signal analysis tasks within a single instrument.

Built-in uncertainty calculator

Computes noise figure uncertainty by auto-populating data from the SNS, USB preamplifier, and key instrument parameters like analyzer noise figure and match.

Maximum frequency 3.6 GHz to 40 GHz

Highlights

The N8973B 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 N8973B. The N8973B 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 prepopulate 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.
