well, that was the tone I got from that message anyways...
I just looked up the TDS3000 manual, and it seems to me that they are using the pulser for tuning the channels' deskew
(hope i am using the term correctly) . They dont mention it in the manual but the setup shows why they needed the pulser
So the rise time is really not that critical as long as it is fast enough so the instrument can measure the delays between the channels
and adjust them. The more important and more expensive equipment in that setup in my view is having the 4 coaxial cables
with exact same electrical length and I believe they probably should be very phase stable
