Internals
Note that the TDS754C&D and TDS784C&D series are nearly identical, with the differences being in front-panel cosmetics and the presence (754) or absence (784) of a few capacitors on the acquisition board. The only other difference is the position of instrument ID jumpers, also on the acquisition board. In fact, it is entirely possible to convert a 754 to a 784 (see abVe Links and the TDS784 page for more information).
Important notice for TDS700D Series: Checking of acquisition board variant is very important — the CPU Board with Firmware 7.xx cannot be used together with the acquisition board, and the CPU board with old Firmware 6.xx doesn't run with the new acquisition board. In this case is both boards's part number "671-4349-00". It tells: It is not safetly indicator for difference firmware.
