[Central-Electronics] CE-100V Power

Couple wild guesses, too much drive from the sweep gen or something wrong
with a termination ??? It's been a while since I had to sweep anything and 
then it was a bit more complex than a 100V.  System sweep from 5Mhz-1Ghz
and it was no fun, think days to get 'er done. Levels were always the critical
part.
