Keysight's new 34465A (6.5 digit) and 34470A (7.5 digit) bench multimeters
HighVoltage:
If you have your 34470A ON for a few hours and the temperature will not change much, you should get a very similar bell curve.
OK, I will do the test again with one of my 34470A over night and see the results tomorrow.
HighVoltage:
These data were taken over about 24 h on one of my 34470A with a shortage block across all 4 input connectors.
splin:
The 34470A noise is double that of the 34465A which is a bit surprising - were they using the same NPLC/filtering/AZ settings? What were the settings?
How come the 34470A is only showing 6 1/2 Digits?
If they were using the same settings then I wonder if the noise difference is normal variance between instruments - I expect the 34465A and 34470A will have the same front end and ADC, the main difference being the reference (and the price!)
HighVoltage:
Both, the 34470A and the 34465A were set to ...
Aperture: 10 PLC
Auto Zero: ON
Input Z: 10 MOhm
I use the same short block on both
I will repeat the test and do both instruments at the same time and also record the room temperature
May be I will add a 34461A for comparison as well.
HKJ:
I also tried letting my 34465A/34470A warm up, do a ACAL and then histogram over 24 hours. Except for histogram settings all parameters are default on the meters.
