Circuit designers are looking at Mu primarily, Rp next and we hardly care about Gm at all. Why then do most vendors measure Gm and Gm alone? Because most testers only measure Gm! No commercial tester ever measured Mu either (until the AMPLITREX AT1000 was introduced.) And even the Hickock, treasured for measuring Gm, doesn’t measure it meaningfully (due to current dependency), accurately (due to calibration difficulties) or consistently (due to internal circuit drift).'"...
