CODE ERR — A bi-phase coding violation (ERRor) has occurred in
the digital data stream. All affected data samples are unreliable, and
are therefore ignored. The instrument treats affected samples as “zero
samples” for use by the meter bars and phase display. When Session
is running, the instrument counts code violations and displays the
total on the Session view.

PARITY — The incoming subframe does not have even parity as
specified by the applicable digital audio standards. The data sample
is unreliable and is ignored. The meter bars and phase pattern treat
the sample as a zero sample. When Session is running, the
instrument counts parity errors and displays the total on the Session
view.
LOW CONF — (Low Confidence.) This warning message indicates a
marginal signal on the serial digital interface. Problems that can
trigger this message — such as significant jitter or low signal
amplitude — will usually result in a poor “eye” pattern when the
serial digital signal is displayed on appropriate equipment.
