DVG7 SD-SDI Digital Generator (shown with Option BK).

HDVG7 HD-SDI Digital Generator (shown with Option BK).

The DVG7 is a multiformat SD-SDI test signal generator. The DVG7
Digital Video Generator supports 525 line and 625 line serial digital
video at 270 Mb/s and NTSC composite digital at 143.181818 Mb/s. The
DVG7 Digital Video Generator has two identical test signal outputs. With
Option BK, two additional identical serial digital black signal outputs are
available.
The HDVG7 is a high-accuracy, multiformat, high-definition test signal
module that provides up to two identical 1.485 Gb/s serial digital video test
signal outputs in a broad variety of formats. With Option BK, two additional
identical serial black signal outputs are available. Ancillary Time Code
(ATC) generation is available when the GPS7 is installed in the TG700
mainframe. Up to two HDVG7 modules can be placed in a single TG700
mainframe.
The digital modules DVG7 and HDVG7 support AV timing mode and up to
16 channels of 20- or 24-bit audio sampled at 48 kHz embedded on the
test signal outputs. The user can independently set frequency and level
for each channel.
Full frame test and custom patterns can be generated for the AVG7,
AWVG7, DVG7, and HDVG7 modules. Simple full frame patterns are
available on V3.1 (or higher than V3.1) CD-ROM.
The HDLG7 is a test signal generator that provides two identical dual-link
high-definition serial digital interface (HD SDI) outputs. The module

HDLG7 Dual Link HD-SDI Generator.

HD3G7 HD/3G-SDI Test Signal Generator

supports video formats that require the use of a dual-link interface, such as
4:4:4 R'G'B' at rates up to 1080i/60 Hz or 1080p/30 Hz, or 4:2:2: Y'C'bC'r
at rates up to 1080p/60 Hz. The HDLG7 supports several standard test
signals, and also has the unique ability to up-convert an arbitrary single-link
HD-SDI input signal to a dual-link format for the outputs. The HDLG7 also
supports digital cinema 2K formats and test patterns.
The HD3G7 is a test signal generator that provides two outputs of a
HD/3G-SDI video test signal. 720-line formats and 1080-line formats
described in SMPTE standards are supported for both Level A and Level B
mapping structures, including 4:4:4 and/or 12-bit sampling, Y'C'bC'r, R'G'B',
or XYZ color space, and 2K digital cinema formats. The 2×SMPTE 292M
HD-SDI format used by some 3D TV applications is also supported.
The HD3G7 can generate up to 32 channels of 24-bit 48 kHz embedded
audio, with independently set frequency and amplitude for each channel.
The HD3G7 also has the ability to generate other types of ancillary data,
such as video payload identifier, ancillary time code, and user-defined
packets.
The HD3G7 includes a wide variety of standard test signals, including
SMPTE color bars, pathological test patterns, and a programmable
moving zone plate pattern, and it also has the ability to up-convert an
input 1.485 Gb/s HD-SDI signal to a 3G output. The HD3G7 has a
clock/frame trigger output that can be used to synchronize the output with
an oscilloscope, for example.
