Diagnostics
Embedded Audio Identifies the presence of up to 16 channels of
AES/EBU digital audio.
Ancillary Data Identifies the presence of ancillary data (other than
audio and EDH) and indicates if a checksum error
has occurred.
Bit Activity Indicates if any of the 10 data bits are always high
or low during the active picture for an entire field.
Line Rate Indicates whether the signal is 525 or 625 line.
Format Errors Warns that a serial signal format error has occurred
for the following error types:
H SAV placed incorrectly relative to EAV.
H Line length error.
H Field length error.
H Reserved values used improperly.
H ANC data checksum error.
H ANC data parity error.
Signal Lost Reports absence of the serial video signal.
Digital Data Value Cursor and Listing
(WFM 601M Only)
Digital Waveform Non-interpolated waveform display. Cursor
identifies selected sample value (hexidecimal,
decimal, binary). Cross-hair cursor inserted on
picture monitor output shows selected line and
sample. Vertical and horizontal shift of picture
monitor output when selecting blanking interval line
and sample values.
Data Mode Displays interleaved data stream sequentially with
31 samples per screen width. Cursor identifies
selected sample value.
Video Mode Displays Y, Cb, Cr data streams separately.
Channels are selected with VIDEO IN buttons.
Cursor identifies the selected sample value.
Digital List Sequential list of sample values in table format.
Cursor identifies selected sample. VIDEO mode
identifies samples as Y, Cb, Cr.
