Operating Basics
detected. The output will remain off as long as the error occurs. Use this
function to trigger a downstream ECO to switch to backup.
BLACK 3 / 10 MHz: Outputs the selected black burst or HDTV trilevel sync
signal. You can also con fi gure this connector to output a 10 MHz sine wave.
(This connector is labeled 10 MHz / BLACK 3 on earlier GPS7 modules.)
NOTE.
You can use the menus to independently set the format and timing of the
three black outputs and to enable VITC to be applied to the output signal.
HD3G7 Module Connectors
The HD3G7 3 Gb/s SDI Video Generator module provides four BNC connectors
as described below. (See Figure 2-13.)
Figure 2-13: HD3G7 module connectors
SIGNAL 1: Outputs the selected HD-SDI serial digital video test signal or an
upconverted version of the input signal on the SDI IN connector.
SIGNAL 2: The Signal 2 output can be con fi gured to output a test pattern,
where it produces the same output as the Signal 1 output, or to output a
Black signal in the same format as the Signal 1 output. (See page 3-183,
SECONDARY OUTPUT Submenu .)
SDI IN: Input connector for an HD-SDI (4:2:2) video signal that you want to
be upconverted.
TRIGGER: Outputs a selected signal. The available choices for output are:
system clock (148.5 MHz), frame/ fi eld pulse (once per video frame or fi eld),
or a line pulse (once per video line).
When an interlaced format is selected, the frame/ fi eld pulse selection produces
a frame-rate square wave trigger output which is low during fi eld one and
high during fi eld two. The frame pulse selection produces the once per fi eld
pulse for all other formats.
NOTE. When the SECONDARY OUTPUT selection is set to Test Pattern the
SIGNAL 1 and SIGNAL 2 connectors output the same test signal.
