Hi Rohit,
Thanks for the links, it helped to decode the D2p marking to be BCW32.
For now, I've decided to disconnect the amplifier from the ADC on the board, and implement my own amplifier on a separate board.
I had wanted to figure out how the board implemented it's gain and offset adjust, but I have a wideband FET amp circuit I'll
try to implement an offset with.
I tried connecting the board to a 'open bench logic sniffer' last night, it makes a cheap scope, and it's open source
unlike KNJN. I had to write a program to convert the saved file into a csv format that Excel could convert into a graph, so
it's still primitive, but workable.
