Is there any way to compensate for EIA (7/8", 1.5" high power) adapters when trying to calibrate high power directional couplers? The adapters are N to EIA but I sure don't have an EIA cal kit for my ENA. I can compensate for thru loss with display math (data/mem) but the SWR of the adapter the problem. The coupler has a max SWR of 1.25 but the adapters alone are about 1.2; my usual results for the combination (adapter/coupler) is about 1.4. Any math I can do manually or with the ENA to "remove" the adapter SWR? Thanks.
