Uh, yeah! If someone has a definitive guide on how to upgrade the 53131 to the 53132 with all the necessary parts, I would definitely buy two from you.

No, the higher resolution is due to a different HW (more precise ADC) with the same gate time.

I realize with the same gate time you would need the additional hardware.  BUT, if you don't/can't get the additional hardware, I think increasing gate time will provide those extra digits.  (Through averaging)

If you don't have a 53131A and can't provide evidence that 53131A still yields 10 digits with gate time of 10 seconds.... then go away.

Shoot, thwarted by obsolete silicon  :(

Well a minimum order of 9 ADCs is not a huge deal if they are actually genuine, given what a 53132A costs I would bet there are easily enough people here who would go in for a couple even at $9 each if we could determine with some certainty what is needed. This is the sort of project that would be well suited to try on a scrapper motherboard that has something else wrong with it. I haven't looked at the datasheet for that ADC yet, is there something special about it or might there be an electrically compatible part in a different package that could be adapted?

If I could get the other digits with a longer gate time that would be reasonable and at least it wouldn't bug me having those digits sitting there unused. I only got the counter recently and fixed it up, I've been using it for basic measurements but have not really delved into what all it can do yet. It's certainly a lot nicer to use than my old Protek counter, I was not even aware until recently that reciprocal counters were a thing. Had I know how much nicer these are I would have bought one years ago.

Being stranded at home (I live in Italy) I was not able to reach my two 53131A units and my notes regarding the differences between the two models, so I made a quick "blink comparison" on the schematic pages.
Attached you'll find the "blink" PDF (Red=53131A/Green=53132A) and an XLSX with the list of the different components.
Hope it can be useful to someone of you....

the spreadsheet has been replaced with an updated one (added C203), due to a suggestion by ytsejam: the older one has been removed

Thanks eliocor! The overlapped schem comparison is amazing!

I've successfully converted a 53131A to 53132A.
