Product Overview

The Keysight N8973A (Agilent) Noise Figure Analyzer is a high performance noise figure analyzer designed to make fast, accurate and repeatable noise figure measurement. With the N8973A ease of use features, you can set up complex measurements simply and easily giving you repeatable and reliable results you can trust. The Keysight N8973A offers simultaneous noise figure and gain measurements with the ability to view, print and save the data / display in multiple formats. The N8973A also has the ability to characterize amplifiers and frequency translating devices, including LO control over dedicated 2nd GPIB. The N8973A offers increased measurement accuracy and faster measurement speed over previous Agilent noise figure meters, as well as six user selectable measurement bandwidths.
