in my separate noise "adventure" with long boring posts (related to this DMM noise logging), i was trying to tinker with my K2015 to lower/find noise problems with my pre-loved korean set. i think i have hit a place where i would need some input from anyone with some relevant data.
i have summarised some of my noise "findings" of my slightly modified K2015 (see pic, atm still collecting 1NPLC data). but i am unsure as to where i stand in terms of pk-pk noise of the DMM (it is influenced by my environment AC noise, as i have yet to get any AC isolation done).
the calculations i used in my sheet are using opencalc, the opencalc SYNTAX for this peak-peak is [MAX(data-range) minus MIN(data-range)] to get the value. it does not exclude outliers
i hope this is not too off topic. if anybody can put out some numbers of your peak-peak noise for comparison, it would be greatly appreciated TYVM
(esp 1v/10v range 10NPLC, and also if any solartron 7081 n any 7.5digits owners
, i am particularly curious at solartron for it is older than 3458a in technology). i recall forumner Robrenz mentioned in a thead he has his tek4050 log 152hrs with only 1uV pk-pk noise, and that was amazing.
then again, should pk-pk data become a part of the main noise data here? (it did help identify popcorn noise in my DMM, thanks to kleinstein)
*edit : there is an error in the PPM range column, 0.1v range PPM should be x10 more
