Above-Bar Warning
Messages
This instrumen
t displays warning messages above the level meter bars. The
warning messages that can appear above the bars as follows:
Clip. The numb
er of consecutive samples equals or exceeds the # Samples
for Clip setting.
Over.Thesi
gnal is at or above the specified Over Level for a time exceeding
the Duration for Over setting.
In-Bar Warning Mess ages
This instrument displays warning messages within the level meter bars. The
warning me
ssages that can appear are shown below in order of priority.
UNLOCKED. The instrument is not locked to an incoming signal on the
indicate
d input channel. Data cannot be decoded and all data and other errors
are ignored. This means that if an AES input is selected, nothing recognizable
is present on the input, or if embedded audio is selected, the VIDEO input is
unrecognizable.
AES PARITY. The incoming subframe does not have even parity as specified
by the digital audio standards. The data sample is unreliable and is ignored.
The level meters and Lissajous display treat the sample as a zero sample.
AES CRC ERROR. The CRC code in the AES channel status packet is
incorrect. Sometimes the CRC code is set to zero, indicating that the signal is
missing; when this is the case, this message is not displayed.
MUTE. The number of consecutive all-zero samples equals or exceeds the
# Samples for Mute setting.
SILENCE. Thesignalisatorbelowthespecified Silence Level for a time
exceeding the Duration for Silence setting.
DISABLED. Indicates that an audio bar is n ot active. This message is mainly
seen with a Dolby Digital source when a listening mode is selected with a
r
educed number of channels.
AES V BIT. Indicates that the Validity bit is set high for one or more data
samples. In the AES/EBU standard, a set validity bit indicates that the sample
is not suitable for conversion to audio. By default, the level meter bars and
Lissajous display treat the a ffected samples as zero samples.
NO AUDIO. Indicates that an AES or embedded input has the Non audio
bit set.
NOT PRESENT. Indicates that an audio bar is not present in the current
audio input. This can be present if a Dolby Digital input has a coding mode
indicating a reduced number of c hannels.
DOLBY D+. Indicates an AES or embedded input is DOLBY Digital Plus.
DOLBY E . Indicates an AES or embedded input is DOLBY E.
