CAUTION
Degradation of some product specifications can occur in the presence of
ambient electromagnetic (EM) fields and noise that are coupled to the
power line or I/O cables of the instrument. The instrument will self-recover
and operate to all specifications when the source of ambient EM field and
noise are removed or when the instrument is protected from the ambient
EM field or when the instrument cabling is shielded from the ambient EM
noise.
