4.4.2.1. Selecting the Standard of the Sync Outputs
OUTPUT
This menu item sets the format of the sync output. All sync outputs including
the 10MHz and Wordclock outputs are fully configurable.
The PAL-B and NTSC-M selections are black burst outputs compliant with
SMPTE ST 318. When either of these standards is selected, Vertical
Interval Time Code can be inserted onto two lines of the VBI. A ten-field
reference can also be inserted onto line 15 of the NTSC-M color black
output. See section 4.4.2.2 for more information.
There are numerous HD tri-level standards that can be output compliant
with SMPTE ST 274, SMPTE ST 296, and SMPTE ST 292-1.
For 1080p/25sF use the 1080i/50 format
For 1080p/29.97sF or 1035i/59.94 use the 1080i/59.94 format
For 1080p/30sF or 1035i/60 use the 1080i/60 format
The 625i/48 and 625i/47.95 selections are “slow PAL” signals, which are
sync only bi-level formats synchronous to 24Hz and 23.98Hz rates.
The pulse formats consist of various timing signals that can be used to line
up signals with different timing. See the pulse diagrams of Figure 2-4 and
Figure 2-5 for more detail. The
PAL color frame
pulse occurs during field 1
of the PAL-B 8-field color sequence. The
1Hz
pulse occurs once per second
at the beginning of the second and indicates the point where the vertical
syncs of 60Hz and 50Hz HD sync formats are coincident. The
1/1.001 Hz
pulse occurs nominally once per second at the beginning of the second and
indicates the point where the vertical syncs of 59.94Hz and 23.98Hz HD
sync formats are coincident and is also aligned with NTSC color field 1. The
6
/1.001 Hz
pulse occurs nominally six times per second and indicates the
point where the vertical syncs of 59.94Hz and 23.98Hz HD sync formats are
coincident. The
IRIG1 datum
pulse will be aligned with the IRIG outputs and
the rising edge indicates the start of the IRIG reference bit. The pulse type is
controlled by the
Pulse type
menu item (see section 4.4.2.2.12).
Wordclock is a 48kHz sampling rate clock that can be phased separately to
the AES/DARS outputs. The amplitude is controlled by the
Wordclock levl
menu item (see section 4.4.2.2.14).
The continuous wave formats output a sine wave at different frequencies.
The amplitude of these outputs is controlled by the
Sine wave level
menu
item (see section 4.4.2.2.13). If the unit is locked to a black burst frequency
reference the subcarrier outputs will be lined up with the reference.
NTSC-M subcarr. = NTSC CW subcarrier frequency at 3.58MHz nominal.
PAL-B Subcarr. = PAL-B CW subcarrier frequency at 4.43MHz nominal.
5 MHz = Continuous sine wave at 5MHz.
10 MHz = Continuous sine wave at 10MHz.
