764 Digital Audio Monitor User Manual

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.
