I'm not sure about Aaron's adaptation board, but here are a couple shots 
from my Easel...

At a slow pulse (probably 10hz):

At high frequency (not sure how high, but well into the audible range):

It flattens out at the bottom a bit but not at the top. Also there's a 
bit slower attack slope.

Hope that's helpful.
