My experience is that you cannot future proof your instruments. I have seen 
it so many times with PROM programmers - "this instrument is software 
upgradable to future proof against upcoming products, the only programmer 
you will ever need"  -oh yeah, within a couple of years you cannot get 
upgrades because things have gone ways they didn't expect, or new 
technologies have come out the they cannot handle ...

The same thing happens with logic analyzers and micro development systems. 
Anyone still using an HP 64000 system? They were designed to be the alpha 
and omega of development systems, but I don't know that they got past 8086 
and 68k systems.

The same seem to go with all other instruments. Even though you are spending 
$30k, it needs to be written off over about 3 years, as by then it will no 
longer be state of the art, just ordinary performance for an instrument in 
its class.

All you can do is purchase against current testing requirements
