3–46 WFM 601A, WFM 601E & WFM 601M User Manual
Features of the Status Screen. The Status screen features operate as follows:
Signal Present. Indicates when a valid serial digital signal is detected. When
the serial receiver detects a no-signal condition, the status will read SIGNAL
MISSING.
525/625 Lines. Gives the number of lines in the serial digital signal.
10/8 Bits. Gives the number of data bits in the serial digital signal.
Audio. Gives the number of embedded audio channels detected in the serial
digital signal. When the serial digital signal does not contain audio informa-
tion, the AUDIO readout disappears.
Format Error. (WFM601E and WFM 601M only) Indicates a format error is
present. To see the type of format error, press the DISPLAY bezel button to
select FORMAT.
Other ANC Data. (WFM 601E and WFM601M only) Indicates the presence
of ancillary data other than EDH or Audio.
Stuck Bits. (WFM 601E and WFM601M only) Indicate if any of the 8 or 10
data bits are locked. The LSB is on the right. Active bits are indicated by a
hyphen and locked bits by an L for the low state and H for high.
FF CRC ERR SEC (full field CRC errored seconds). Provides an EDH
(SMPTE RP-165) measure of asynchronous errored seconds based on CRC
calculated for each field in the video signal.
AP CRC ERR SEC (active picture CRC errored seconds). Provides an EDH
(SMPTE RP-165) measure of asynchronous errored seconds based on CRC
calculated for the active picture part of each video field.
F1 AP CRC VALUE (active picture CRC value). Calculates the AP CRC
value for the active video part of field one.
F2 AP CRC VALUE (active picture CRC value). Calculates the AP CRC
value for the active video part of field two.
Changed Since Reset. Indicates if either the F1 or F2 AP CRC VALUE has
changed since you last reset the timer.
Elapsed Time. Gives the time since you last reset the timer.
Reset. Sets the elapsed time back to zero and clears any detected EDH errors.
Display. (WFM601E and WFM 601M only) Selects either STATUS,
FORMAT, or CABLE screens.
