B&K precision 2190B Schematics Manual??
Does anyone have the calibration and schematics manual for the BK Precision 2190B? While the number is quite similar, the scope actually appears to be rather different than the 2190. -

Re: B&K precision 2190 3 Channel Oscilloscope
B&K Precision 2190B 100MHz analog scope - From that ko4bb schematic, the B+K scopes 2120B, 2125A, 2160A, 1541D are the same chassis but 30MHz. They might match, but 100MHz league uses higher voltage on a second anode.
You will find they are usually a Korean build like many other analog scopes- that look the same on the front panel. So sometimes you can cross ref to another brand's model number and use that service manual. Protek (Hung Chang) might be the manufacturer.
B&K Precision 2190D 100MHz DSO replaced by B&K 2190E. It looks just like Siglent SDS1000CNL series.Last edited by redwire; 08-04-2020, 11:24 PM.Comment

Anyone run memory speed tests with an old X58-based triple channel 1st gen or any other >2 channel board? The one I have is a Gigabyte I think.
Anyway I had four 4GB DDR3-1333 modules in the 6 memory slots and got around 11GB/sec memory speeds assuming that it went dual channel since it didn't have enough modules for triple channel. Now I stuck in two more 4GB modules, but they are DDR3-1600. I'm still getting 11GB/sec speeds according to memtest86...
Just wondering, anyone do memory speed analysis on these triple (and higher) channel memory boards? Are there any... -
