CRC STATUS tab display
Use the CRC STATUS tab display to view the status of CRC and Checksum errors
in the video signal. (See
Figure 124
.)

NOTE.
The instrument uses the SMPTE RP165 standard for error checking. For
HD and 3 Gb/s signals, the CRCs change on every video line.
•
Y Chan CRC Error
: Displays the status of the Y channel embedded
CRC (Cyclical Redundancy Check) that was calculated for the video
signal. Using a known test signal, the CRC status can be used to verify
integrity through a system. An error means that the Y Channel embedded
CRC value does not match the calculated CRC value, which indicates that
a transmission error has occurred.
•
C Chan CRC Error
: Displays the status of the C channel embedded
CRC (Cyclical Redundancy Check) that was calculated for the video
signal. Using a known test signal, the CRC status can be used to verify
integrity through a system. An error means that the C Channel embedded
CRC value does not match the calculated CRC value, which indicates that
a transmission error has occurred.
