First look at GlueX Preamp response with FDC

[Simon Taylor <staylor@jlab.org>]

Hello, everyone.

Fernando and I looked at real signals from the FDC prototype using the
GlueX preamp boards this afternoon.  The pulses were generally quite large
to the point of possibly saturating the output of the shaper board I am
using to look at the signals.  The noise level was low.
I have put some photographs of scope traces on the web in the FDC logbook
