3.1.2. Test Generator Options
A variety of audio and video test generators are available.
+SDI-TG and +10G-TG Options:
• Serial Digital Interface Test Generators (SDI TGs). There are four independent test generators.
The SDI-TG option provides the capability to generate Standard Definition formats. The HDTG
option adds the ability to generate High Definition formats. The 3GTG option adds the ability to
generate 3G formats as well as dual-link formats. The 3GTG option also includes 3D test
patterns in various formats. All test generators have an audio embedder and can generate audio
tones in up to four groups of audio. They also feature a 2-line configurable on-screen message
display and timecode burn-in window at the bottom of the image.
+AUX Option:
• Analog Audio test generators. Two channels, Left & Right. Supplied as balanced outputs on the
AUDIO terminal block. Can be configured to output continuous, or timed audio tones.
• Digital Audio test generators. Two AES outputs with configurable audio tones and a silent DARS
output. Provided as unbalanced outputs on HD-BNC connectors and also as balanced, isolated
outputs on the AUDIO terminal block.
3.1.3. Global Pedestal Control
There is a single control to enable or disable applying 7.5IRE setup to all sync outputs. This control
only affects the NTSC-M output format. This control is located in the OUTPUT root menu.
3.1.4. Global Phase Controls
The Global Phase feature of the 5700MSC-IP provides a single point of control from which all video
outputs can be phased simultaneously. There are separate controls for each of the frequency lock
modes (GNSS+, Video, 10MHz, and Internal) to allow different phase offsets to be applied depending
on the lock source. This global phase allows for phase correction to be applied when locking to a
10MHz reference.
The “10MHz” and “Internal” global phase settings are reset to zero at startup. This is
done because no phasing information is supplied in these reference modes and the
phase of the outputs will be random when the unit is restarted.
Once enabled, the global phase offset can be specified in milliseconds, microseconds, and
nanoseconds. The global phase offset is applied before the individual phase controls for each output.
Refer to Table 3-1 for a list of all the outputs affected and the minimum phasing resolution for each.
The outputs unaffected by global phase will remain locked to the reference. The Global Phasing menu
in the OUTPUT root menu is used to configure global phase.
