No excuse for crappy measurements!

Witness the new Keithley/Tektronix DMM6500.
6.5 digits.
min range DC 100nV, 10pA; AC 100nV, 100pA
R: down to 1uOhms, C down to 0.1pF.
Etc, etc.

I remember that such high performance, scientific instruments cost north of $ 10k.
This one is ... drum roll ... $ 1600.
I know, it's serious money, but still. No bench should be without it.

I have a multimeter with a very elaborate circuitry spread over two PCBs. It is not an expensive model like this one and it is plagued by dry joints. I only hope that expensive models use a soldering method which does not result in many dry joints. Modern solder unfortunately, is too brittle, and can easily develop dry joints.

An HP 3456A is a couple hundred on ebay. Its doesn't have USB or logging, unless you want to mess with HPIB, but I'll never part with mine. Still one of the most accurate meters I've used in 40 years.
I would like to have a logging type meter but I never get around to buying one.

Now that is a boat anchor!

I like the idea of it, but it's likely that very few if any home hobbyists will do anything needing that kind of measurement capability. It's a lot for the money, though.
