Measurement Uncertainties – SOLT/SSST
The graphs give measurement uncertainties after the above calibration. The errors are worst case contribution of residual directivity, load and
source match, frequency response and isolation, network analyzer dynamic accuracy, and connector repeatability while noise effects are added
on an RSS basis. 10 Hz IF Bandwidth is used. For transmission uncertainties, it is assumed that s11 = s22 = 0. For reflection uncertainties, it is
assumed that s21 = s12 = 0. For other conditions, please use our free Exact Uncertainty calculator software, downloadable from the Anritsu web
site
