3458 latest upgrades

[acts238willy]

The 3458, my favorite DMM, has gone far beyond my 1990 model... The HFL, for example. Questions about the upgrades....
1) Is the HFL option just a high quality reference, or are there other differences in the machine to go along with the reference?
2) Is there a Hi voltage AC option? I use probes now, which introduce errors.
3) How much SMT is included in the newest machines? I've seen it on A/D daughter boards, so far. Since production has moved offshore to Asia where lots of SMT is made, how much is now incorporated?

the 3458 was going to be discontinued but it is so good they made the changes instead.  I have used this meter for 100 years but didn't realize all the stuff it could do until I worked at Hill AFB
