  "description": "This is a collection of data sets acquired for measurements of noise figure and receive system noise of wireless/radio frequency receivers and transceivers. These data include tabular data that list\n\n1) Inputs: calibrated input signal and excess noise levels, and\n\n2) Outputs: summary statistics for each type of user data collected for each DUT.\n\nThe experiments that produced these data were meant to be used to assess noise measurands, but the data are generic and could be applied to other problems if desired.\n\nThe structure of each zip archive dataset is as follows:\n\n| Root\n\n|-- (Anonymized DUT name 1)\n\n|---- Data file 1\n\n|---- Data file 2\n\n|---- ...Data file N\n\n|---- DUT-README.txt\n\n|-- (Anonymized DUT name 2)\n\n|---- Data file 1\n\n|---- Data file 2\n\n|---- ...Data file N\n\n|---- DUT-README.txt\n\n| (etc.)\n\nData tables in each archive are provided as comma-separated values (.csv), and the descriptive text files are ASCII (.txt). Detailed discussion of the test conditions and data formatting is given by the DUT-README.txt for each DUT.",

It includes input conditions calibrated at the DUT input, as well as verification tests performed in cascade with a calibrated reference LNA. \n\nTabular data are given as .csv files. These are documented in accompanying DUT-README.txt files, which also detail relevant experimental parameters.",

The DUTs were 1 access point (AP) and 1 client, operating at 5.3 GHz. The measurements were performed for each DUT at both 1) its input and 2) in cascade with a calibrated reference LNA to verify the test method. Tabular data are given as .csv files.
