Any idea what frequency the ripple was?

We weren't able to get a good measurement on the ripple due to difficulty getting the oscilloscope to trigger, but it was approximately 2KHz by our reckoning.
The 5v I mentioned isn't the 5v output on the PDB itself, it's the output of the DC-DC converter after the +12V radio output on the PDB. We don't use an Axis camera on our robot, and so the dedicated 5v on the PDB is disconnected (Sorry for the confusion, I'd completely forgotten that there was a 5v output on the PDB).
