My big Tek analyzer has 128K per channel, 96 channels per board, and I think that is actually two bits/sample for the glitch memory. It takes maybe six seconds to format up the region you are viewing, and every couple pages you scroll in time, it takes another six seconds to do it over for the new region. Kind of a pain to find what you are looking for. On the other hand, it can capture several servo periods at something like 20 ns per sample.
