REF LOOP (loop)
This pair of BNCs allow the input of a remote reference signal. This signal may be
one of several different formats, ranging from PAL or NTSC Black-Burst, or any
format of Tri-Level Sync.
With the reference signal applied to one BNC, the other BNC must be terminated (or
connected to another unit which is ultimately terminated).
If the CY460 Sync Pulse and Test Pattern Generator is to be used as a Master
reference (i.e. not genlocked), you do not have to supply a signal, and you may leave
these BNCs unconnected. However, it is always wise to add a termination onto one
BNC of an unused looping pair, in order to avoid having a “floating” input.
COMPOSITE (output)
This pair of BNCs provides two outputs of the selected Analogue Composite Video
Pattern. The output format can be PAL, NTSC-M or NTSC-J.
BLACK 1 (output)
This pair of BNCs provides two outputs of Analogue Composite Video Black-Burst.
The output format is always the same as that selected on the COMPOSITE output.
TRI / BLACK 2, 3 & 4 (outputs)
These three pairs of BNCs provide two outputs each of either Analogue Composite
Video Black-Burst in PAL, NTSC-M or NTSC-J, or any one of the supported (and
option enabled) Tri-Level Sync formats. These three pairs of outputs are completely
independent from each other. Additionally, they are able to output a selection of
fixed frequency signals, namely PAL or NTSC Subcarrier, 10MHz, etc.
SDI 1 & SDI 1 BLACK (outputs) & SDI 3 & SDI 3 BLACK
These two pairs of BNCs provide two outputs each of the selected pattern and black
in Standard Definition, and when the relevant options are enabled, High Definition
and 3G Video, in any of the supported formats. The signal format of the black output
follows that of the Pattern output.
SDI 2 & SDI 2 BLACK (outputs) & SDI 4 & SDI 4 BLACK
These two pairs of BNCs provide two outputs each of the selected pattern and black
in Standard Definition, and when the relevant options are enabled, High Definition
and 3G Video, in any of the supported formats. The signal format of the black output
follows that of the Pattern output.
100-Base T (input / output)
This rear-panel connector is a standard RG45 Ethernet connector. This is used
initially at the factory to upload the SPG software. After installation, it may be used
to upload software updates. Additionally, other remote connections are achieved
through this interface, i.e., to the remote control desktop program DashBoard, and
when the CY460 Sync Pulse and Test Pattern Generator is configured as an NTP
Server, etc.
