Display Information
instrument uses the SMPTE RP165 standard for error checking. For HD and
3 Gb/s signals, the CRCs change on every video line.
F2 AP CRC
: For SD signals only, calculates and displays the active picture
CRC (Cyclical Redundancy Check) for
fi
eld two in hexadecimal. The
instrument uses the SMPTE RP165 standard for error checking. For HD and
3 Gb/s signals, the CRCs change on every video line.
Data Collect
: Shows the state of error gathering. The possible states are:
Running
: Indicates errors are being gathered and displayed on the status
page.
Stopped
: Indicates errors are not being gathered. The status page is not
being updated.
Resetting
: Appears brie
fl
y after the SEL button is pressed to reset the
statistics.
Runtime
: The time since the last reset occurred. Time is displayed as "DD,
HH:MM:SS", where DD is the number of days, HH is the number of hours,
MM is the number of minutes, and SS is the number of seconds.
Stuck Bits
: For SD signals only, displays which of the video bits are stuck. If
the readout is "—- —- –", then none of the bits are stuck.
Y Stuck Bits
: For HD signals only, displays which of the luminance video
bits are stuck. If the readout is "—- —- LL", then none of the bits are stuck.
LL is displayed for the two unused bits.
C Stuck Bits
: For HD signals only, displays which of the chrominance video
bits are stuck. If the readout is "—- —- LL", then none of the bits are stuck.
LL is displayed for the two unused bits.
EDH Error
: For SD signals only, indicates that there is an error in the EDH
packet (checksum or parity) of the signal.
Statistics
: This section of the display shows the status and statistical values
for certain errors. For information about the errors in this section, view the
help
fi
le in your instrument: while the Video Session is active in a tile, press
the HELP button.
Status
: Shows the status of the associated error as either OK, Invalid,
Missing, or Error.
Err Secs
: The number of seconds, since the last reset, that contained at least
one error.
Err Fields
: The number of
fi
elds, since the last reset, that contained at least
one error.
% Err Fields
: Shows a calculated number showing the percentage of all
fi
elds since the last reset that contained at least one error.
