5.4.1. Configuring the Sync Outputs
5.4.1.1. Selecting the Standard of the Sync Outputs
This menu item sets the format of the sync output. All sync 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.
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. 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
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 IRIG
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.
Wordclock is a 48kHz sampling rate clock that can be phased separately
to the AES/DARS outputs.
The continuous wave formats output a sine wave at different frequencies.
If the unit is locked to a black burst frequency reference the subcarrier
outputs will be lined up with the reference.
NTSC-M subcarrier
= NTSC CW subcarrier frequency at 3.58MHz
nominal.
PAL-B subcarrier = PAL-B CW subcarrier frequency at 4.43MHz nominal.
5 MHz = Continuous sine wave at 5MHz.
10 MHz = Continuous sine wave at 10MHz.
