AFAIK, there is no special firmware. Early 3458A's did not have the VHP101
reference resistor, but these were (silently) added by default in later
models. So, later models will have much improved resistance specs in some
of the ranges.
Not *all* VHP101 resistors are the same. Some of them are s

Considering to pimp-up my DVM for a while, but would like to know first if
anyone here saw actual PCB photos or have any information of what hardware
actually different in Fluke's HFL version of 3458A. Based on Fluke's manual DC
reference (A9 PCBA) and reference resist
