Blown E4407B... bad RYTHM?

I am repairing an E4407B at work (blown attenuator) but I think there is another issue. Look at this screen upon power up:

The high noise floor should NOT be there. Drops at almost exactly 3 GHz. Suspect the RYTHM module was also damaged.


Any thoughts on that? PLEASE!
