Keysight's new 34465A (6.5 digit) and 34470A (7.5 digit) bench multimeters

I realize this isn't a Keithley thread, but if anyone would like to see similar screenshots from the k7510 for comparison I'd be happy to post them.

That would be great.. I would appreciate seeing examples from your instrument, here.
The 7510 can do scripts, which may overcome some of the formatting problems, probably.
For sure, it can do something like this, expressing the whole statistics in ppm.. gives much bigger resolution for the StD value..
That's 10V from the 5442A, reading is 1.9ppm high, but about 0.097ppm StD, which really is worth 7 1/2 digits.. 34470A and 34465A are identical in hardware, aside from the reference.
I've simply chosen M = 100,000, B = 1,000,000, and ppm as unit.

By using the Math Scale function, you might either substract the average value (B = 2.500 000V), with a resolution of 1µV, and the window is now controllable in Center and Span to fractions of µV. Note also, that the instrument displays down to the resolution of the A/D, about 8 digits, or 100nV.

Ooh, that's nice. Why didn't I think of this! :-+

mx+b is a built in math function, but outside of the program area/scripts, I can't change the unit. :'(

Is anybody here, who has a good contact to Keysight/Agilent/HP, who could ask for solving this bug?

Howdy. I'll pass this thread along, although I'm pretty sure this team monitors the forum.
