That's what I was thinking. I don't understand why we have to use microscopes and scalpels for 1.8 MHz.
It all depends on the degree of precision that you need for whatever project you happen to be working on. I work all bands between 1.8 MHz and 900 MHz, and I occasionally need test equipment for all of them.
Also, errors can add with either a positive or negative sign, as a phase angle. Impedance measurements with a vector analyzer are done with a mathematical equation that can be the difference of numbers that are nearly equal, so a small error in the raw data can cause a greater error in the measured Z.
