Hi guys,


I read carefully all your debates about the voltage references and internal
constructions of the famous 3458A or 34401A, but I wonder why nobody ever
speaks about the 34420A. According to the datasheet, it seems to outperform
the 3458A with small signal measurements. Does anybody have some experience
with this meter or know what's inside ? Is it a tuned 34401A or something
different ?
