its rg400 cable with the 4191A
Any frequency settings. I just wanna see how it degrades. I have a few coax of different length I made up with RG400.
I have a BNC open (rubber gasket), closed (gold shorting pin) and 50ohm load. The idea is to perform cal at just the adapter, then test the unknown at some suspected frequency, then put on the cable, calibrate at end of cable, and attach unknown again to see.
I am wondering if different impedance parameters will display greater error with cables. I want to see the deviation from the unknown DUT tested right at the calibrated port vs the DUT tested at a supposedly calibrated end of a long cable.
the unknown DUT would just be a SMD part soldered into a coaxial connector. I wonder what DUT would show the biggest error to highlight the importance of cable quality/length.
