The Agilent/Keysight N8975AZ is a high-performance noise figure analyzer designed for accurate and repeatable noise figure measurements. This instrument offers a frequency range of 10 MHz to 26.5 GHz in a single unit. It is engineered for ease of use, enabling users to set up complex measurements efficiently, leading to reliable and repeatable results. The N8975AZ facilitates simultaneous noise figure and gain measurements, with the capability to display, print, and save data in various formats. This analyzer is also adept at characterizing amplifiers and frequency translating devices, including local oscillator (LO) control over a dedicated GPIB interface. Advanced calibration techniques and a user-friendly interface contribute to its suitability for demanding applications. For extended frequency coverage up to 110 GHz, the N8975A platform supports K-Series block downconverters.

* Performance verification and calibration guides are available.
**Noise Sources:**
* Compatible with SNS series noise sources (e.g., N4000A, N4001A, N4002A).
* Also compatible with 346 Series noise sources.
* Smart noise sources automatically download calibration data, saving time and improving reliability.
**Interfaces:**
* APC 3.5 (m) connector as standard.
* K-Series block downconverters utilize connectors such as APC 2.4(m), WR15, and WR10 depending on the frequency band.
* LO GPIB connector for controlling external LOs.
* Optionally, N-type (f) input connector.
