As per my knowledge of VNAs this should have been a very easy REFLECTION measurement.
According to the results I get, ...it is not.
I know: the setup itself is questionable due to the differences between Golia (the R3361B) and David (the miniVNA). But this is what I have in hands and this is an experiment done for the purpose of learning something, not to perform actual measurements.
Equipment:
ADVANTEST R3361B Spectrum Analyser;
vanilla miniVNA (no Pro, no lite, no tiny, ...nothing);
VNA-J software versione 3.4.8;
BNC adaptors from China (!);
All VNA calibrations are made for an OPEN over a 1-180MHz range with 6k points.
To make a prove of work I first calibrated the miniVNA for REFLECTION with a M2M BNC adapter followed by a F2F adapter. The calibration plan is expected to be located at the free side of that last adapter (far left end in the picture).
