Keysight N8975B, NF7-class Noise Figure Analyzer, 10 MHz, 26.5 GHz, multi-touch

When you design or test RF and microwave circuits, the biggest headache is getting reliable noise figure data. Inaccurate numbers can hide problems, cause costly redesigns, and delay product launch. You need an instrument that can measure from low MHz up to tens of GHz with tight uncertainty, and that is easy to use on the bench. The Keysight N8975B delivers exactly that, giving you fast, precise noise figure and gain data in a single, intuitive package.

Keysight N8975B, NF7-class Noise Figure Analyzer, 10 MHz, 26.5 GHz, multi-touch with Keysight

The Keysight N8975B is a NF7-class Noise Figure Analyzer that covers 10 MHz to 26.5 GHz. It combines a multi-touch screen, built-in calibration, and simultaneous noise figure and gain measurement. Engineers who struggle with separate spectrum analyzers and noise sources will find this all-in-one solution saves space and time. With 0.02 dB uncertainty and a 1 Hz to 8 MHz measurement bandwidth, you can trust every reading for critical designs.
