Video Not H D
Indicates tha
t the selected SDI video input signal is not an HD format
Line Number Error
Indicates th
at the encoded line number differs from the counted line number
Y Chan CRC Er
ror
Indicates t
hat the encoded CRC for a line’s Y (luminance) samples differs from the
calculated CRC
C Chan CRC Error Indicates that the encoded CRC for a line’s C (chrominance) samples differs from
the calculated CRC
Y Anc Checksum Error Indicates that the encoded checksum in a Y (luminance) ancillary data packet differs
from the ca
lculated checksum
C Anc Chec
ksum Error
Indicate
s that the encoded checksum in a C (chrominance) ancillary data packet
differs from the calculated checksum
Table 51: SD SpecificAlarms
Alarm Description
AP CRC Error Indicates that encoded AP (active picture) CRC differs from the calculated CRC
FF CRC Error Indicates that encoded FF (full field) CRC differs from the calculated CRC
EDH Error
Indicates that EDH ( error detection and handling) has detected an error
Table 52: Composite SpecificAlarms(Opt. CPS)
Alarm Description
Cmpst Input Missing
Indicates that no signal is detected on the selected composite video input
Cmpst Lock
Indicates unable to lock to the selected composite video input
Table 53: Audi
oAlarms(Opts. ADandDDE)
Alarm Description
Over Indicates tha
t the signal has exceeded the level specified by the Over Level setting for
the period of time specified by the Duration for Over setting.
Silence Indicates that the signal has fallen below the level specified by the Silence Level setting
for the period of time specified by the Duration for Silence setting.
Clip Indicates that the number of consecutive, full-scale digital audio samples monitored has
exceeded th
e value specified by the Number of Samples for Clip setting.
Mute
Indicates
that the number of consecutive,“0” digital audio samples monitored has
exceeded the Number of Samples for Mute setting.
AES Unlocked Indicates unlocked condition of an AE S input.
CRC Error Indicates that the AES channel status CRC as calculated by the instrument does not
agree with the CRC embedded in the channel status bytes.
VBit
Indicates that the Validity bit is set high for one or more AES audio samples. In
the AES /
EBU standard, a set validity bit indicates that the sample is not suitable for
conversion to audio.
AES Parity Indicates incorrect parity in one or more AES audio samples.
