Measure your processing delay: put in a delta function and see how many
samples it takes to come out. You should be able to estimate the
processing delay if you know how many clock cycles there are between
samples in and samples out, but measurement is easier.
Once you know the processing delay, subtract that from the output channel.
Then when you plot the in vs out graph, the timing will be reasonably well
lined up.
A real delta function is just a single sample wide pulse, but you can go
up to two samples wide to make sure you don't miss it (assuming the source
signal is not tied to the sampling clock).
