Hello BUMers,

A few months ago we replaced our AM300 console with a new DPX console. For the
samples we pass on this instrument (polymers : PP, PE, ...), we are mainly
interested in the high-field part (60-0 ppm). So taking advantage of the
digitla filter, we limit our Sweep to this range, dropping out the aromatic
solvent signals.

For some time everything was allright. Then appeared artifacts : out of phase
peaks at regular intervals (~800 Hz) to both sides of the main signals. Using
an extended Waltz, the artifacts seemed (?) to have disappeared for sometime,
but now they're back "splendid as ever" :-( ...

Did anybody of you encounter similar problems ? Help would be greatly
appreciated,

Reiner Dieden
