Well that is interesting.
I wonder why they did such a major redesign on the 34972A if they weren't updating the DMM?
- Removing the GPIB interface
- Add LAN
- Add USB
- Add LXI
And probably solving lots of problems with the older design like with the battery and FRAM.
But I am surprised as well, of how much effort was put in to the re-design.
I've always preferred the 34401A over the later 6 1/2 digit DMMs because it doesn't have a fan, but there does seem to be a real performance gain
Yes, I agree.
And even with some 34410A and 34461A meters around, I like to gram the 34401A for most of my daily measurements.
May be just habit.
The fan noise of the 34410A can be reduced with a lower fan speed / different fan.
Back to the 34972A
It seems the screen update rate is also higher on the new model, compared to the old one.
