Keysight Technologies Inc. Noise figure measurements
The Keysight N9933C-356 is a software option for the FieldFox N9933C Handheld Microwave Spectrum Analyzer, enabling noise figure and gain measurements. This option allows users to make accurate noise figure and gain measurements of amplifiers, mixers, and other devices directly in the field. The N9933C-356 supports Y-factor noise figure measurements using a noise source, and provides graphical displays of noise figure and gain versus frequency. It is designed to help engineers and technicians characterize low-noise devices and troubleshoot system performance with confidence, leveraging the rugged portability of the FieldFox platform.
