The following graphs provide measurement uncertainty accuracy at 23°±C after vector error correction for the standard
N connector types. The errors are worst-case contributions of residual directivity, source match, frequency response,
network analyzer dynamic range, and connector repeatability. In preparing these graphs, Fixed CW is ON. Calibration
components 22N50 and 28N50-2 are used.
