Sideband problems on an Omega

Members,

We have recently started getting very low intensity
sidebands on carbon spectra taken on our Omega 600. These
occur at about 655 Hz, 1315 Hz and 2209 Hz on both sides
of carbon signals. The intensity is low ( 2/10,000 ).
The sidebands are coherent and seem to be approximately
the same phase as the rest of the spectrum.

1. Has anyone seen sidebands at these freq. on an Omega?
2. Does anyone know where these freq. could be used in
or generated by the console?

Thanks,
David Redwine
