fluke 123 \ 124 \ 125

[R_G_B_]

I have been reading the specification for the fluke 120 series

They all sample at 25 Ms/S.

So how can the Fluke 124 and Fluke 125 have a bandwidth of 40Mhz at 25Ms/S

The only way I can see if this is possible is if they interleaved the two ADC inputs

The circuits diagrams are the same?

Anyone got an answer?
