First my english is not very good........
I must make a pre-trig with an adc08b200. (data before an after an event in the buffer)
The most efficient way would be to use a digital comparator at the output of 8 bits pins. However it seems, if I read correctly the datasheet, when the buffer is used, the signals do not sort the 8 bits output pins.
Is it the case?
Otherwise the only other way to make a pre-trig would be to add an analog comparator and stop the converter after a number of cycle.
What is the right method?
Thank you
Daniel
