IC FED v1 Status M. Noy 24-07-2003
2
FEDv1 10pF capacitors in parallel with analogue
opto-rx termination resistor found and removed
from top side only (story continues.) Parameters
for optical link, and post-link, should now be
set up correctly (avoiding saturation in all
possible areas)

typical OTC output (across AOH termination)
6
Zoom of Unknown 1 Phase systematics
7
Zoom of Unknown 2 ADC pre-pulse undershoot
8
Plan Investigate the pulse shape anomalies
spectrally - ?require nonuniform dft Look
into random noise, briefly to check the level.
