WFM 601A, WFM 601E & WFM 601M User Manual
Features of the Status Screen. The Status screen features operate as follows:
H 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.
H 525/625 Lines. Gives the number of lines in the serial digital signal.
H 10/8 Bits. Gives the number of data bits in the serial digital signal.
H 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.
H Format Error. (WFM 601E 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.
H Other ANC Data. (WFM 601E and WFM 601M only) Indicates the presence
of ancillary data other than EDH or Audio.
H Stuck Bits. (WFM 601E and WFM 601M 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.
H 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.
H 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.
H F1 AP CRC VALUE (active picture CRC value). Calculates the AP CRC
value for the active video part of field one.
H F2 AP CRC VALUE (active picture CRC value). Calculates the AP CRC
value for the active video part of field two.
H Changed Since Reset. Indicates if either the F1 or F2 AP CRC VALUE has
changed since you last reset the timer.
H Elapsed Time. Gives the time since you last reset the timer.
H Reset. Sets the elapsed time back to zero and clears any detected EDH errors.
H Display. (WFM 601E and WFM 601M only) Selects either STATUS,
FORMAT, or CABLE screens.
