WVR610A & WVR611A Waveform Rasterizers Service Manual
The WVR610A & WVR611A display warning messages above the level meter
bars. The warning messages that can appear above the bars are shown below.
CLIP.
The number of consecutive samples is at or exceeds the # Samples for Clip
setting.
OVER.
The signal has been at or above the specified Over Level for a time
exceeding the Duration for Over setting.
The WVR610A & WVR611A display warning messages within the level meter
bars. The warning messages that can appear are shown below in order of priority.
UNLOCKED.
The instrument is not locked to an incoming signal on the indicated
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 is at or exceed the # Samples
for Mute setting.
SILENCE.
The signal has been at or below the specified Silence Level for a time
exceeding the Duration for Silence setting.
DISABLED.
Disabled can appear for three reasons:
H
Analog audio is selected as the bar source, this causes bars 7 and 8 to say
DISABLED since there are only 6 analog inputs.
H
Embedded audio is selected as the bar source when Composite video is
selected as the video input. Since there is no embedded audio in composite,
all of the bars will say DISABLED.
H
If the currently selected audio source’s Bar to Input Map does not have all of
the bars mapped to inputs, any bars that are unmapped will say DISABLED.
