Measurement Uncertainties – Extended-E Band – SSLT
The graphs give measurement uncertainties after the above calibration. The errors are worse case contribution of residual directivity, load and
source match, frequency response and isolation, network analyzer dynamic accuracy, and connector repeatability. 10 Hz IF Bandwidth is used.
For transmission uncertainties, it is assumed that s

= s
22
= 0. For reflection uncertainties, it is assumed that s

= s
12
= 0. All calibrations and
measurements were performed at default port power. For other conditions, please use our free Exact Uncertainty Calculator software, available
