I decided to compare VF measurements using 4 different pieces of equipment on the same coax cable. Equipment used: RigExpert AA-170, Picoscope 3206D with homemade TDR, Bside component tester, and a Klein Tools MM400 DVM.

The cable was an OPEK RG-58/U (radio shack variety) previously cut as a 1/2 wavelength 11m cable for measuring antenna feed point impedance's. To my surprise, the Bside component tester managed to yield a number almost identical to the TDR measurement.

I shared the PDF of all the pictures i took along the way on google drive. its 14 something MB
