TG700

Features & Benefits

Multiformat Analog and Digital Test Signal Generation

Ideal Channel Configuration and Performance to Support Reference Generator Needs

Modular Expandable Platform

Applications

Reference Generator and Test Signal Generator for Post-production and Broadcast Facilities

Test Signal Generator for Research and Development

Equipment Design and Maintenance

The TG700 is a multiformat, analog and

digital, precision signal generation platform.

Designed with the changing needs of the

video industry in mind, the TG700 offers

sync pulse generation and test signal gen-

eration for a wide array of analog, serial

digital, and digital high definition formats.

The TG700 Multiformat Video Generator

has a modular architecture that offers the

flexibility to meet the single format and

growing multiformat needs of the video

professional. The TG700 mainframe allows

up to four of the following modules to be

fitted in the mainframe.

The TG700 has a high stability reference.

The AGL7 Analog Genlock Module adds

the capacity to lock to a variety of signals,

which makes the TG700 an ideal solution

as the master house reference or slave ref-

erence for broadcast and production/post-

production applications. Three black outputs

are available and are selectable for HDTV

tri-level or NTSC or PAL. Additionally, the

AGL7 can lock to a variety of formats to

include NTSC/PAL black and HDTV tri-level

as well as 1, 3.58, 4.43, 5, and

10 MHz CW.

Multiformat Video Generator

TG700

The ATG7 Composite Analog Test Generator

supports PAL, NTSC, and NTSC NoSetup.

It provides one test signal output, one color

bar test signal output, and two black outputs.

The black outputs can independently gener-

ate H, V, Blackburst, and subcarrier.

The AVG7 is an Analog Video Generator for

525/625 interlace formats supporting com-

ponent (Y’P’bP’r, G,B,R, Y/C), 525 Beta, and

composite (PAL, NTSC, NTSC NoSetup). It

provides two identical component outputs,

two identical Y/C and Composite, or six

identical composite outputs.

The AWVG7 is an Analog Wideband Video

Generator that supports a variety of HD

analog component formats (Y’P’bP’r or

GBR). The module provides two identical

component outputs with a bandwidth of

30 MHz. Up to two AWVG7 Analog Wideband

Video Generators can be placed in a single

TG700 mainframe.

The AG7 provides eight channels (four

AES/EBU pairs) of audio signal generation.

It also provides two channels (1 AES/EBU

pair) of silence as well as a 48 kHz

clock output.

The BG7 is an analog black generator with

four independently selectable outputs. The

BG7 Black Generator supports NTSC and

PAL black burst as well as HDTV tri-level

sync. With Option CB, two of the outputs

can also generate various analog NTSC and

PAL color bar test signals.

DVG7 (shown with Option BK).

The DVG7 is a multiformat test signal gen-

erator. The DVG7 Digital Video Generator

supports 525 and 625 component digital

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.

HDVG7 (shown with Option BK).

The HDVG7 is a high-accuracy, multiformat,

high-definition test signal module that pro-

vides 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. Up to two HDVG7 HDTV Digital

Video Generators can be placed in a single

TG700 mainframe.

The digital modules DVG7 and HDVG7 sup-

port 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.

AGL7, Analog Genlock Module

PAL-M and PAL-N are not supported by AGL7.

Reference Input

Loopthrough Input –

Input connector: 75 Ω x2. Input signal: NTSC/PAL black burst or HDTV tri-level sync. Amplitude range: Standard ±6 dB. S/N ratio: >40 dB. SCH phase: 0 ±40º.

Return Loss – ≥30 dB 5 MHz to 30 MHz.

Burst Lock/Sync Lock Stability –

±3 dB amplitude change: <1 ns. Jitter with burst lock: <0.5º. Jitter with sync lock: <1 ns.

CW Input

Input Impedance – 75 Ω, internal term. Input signal: CW (continuous wave). Amplitude: 2 V (1 to 2.25) V Frequency: NTSC/PAL FSC, 1/5/10 MHz. Return loss: >30 dB to 30 MHz.

CW Lock Stability –

Over the amplitude range: <1 ns. Jitter: <1 ns (typ. 1º) with CW input S/N >50 dB.

Genlock Time Adjustment –

Range: Anywhere in the color frame. Resolution: <0.5º of NTSC/PAL subcarrier. 1 ns with tri-level sync input.

Color Framing – Keeps accuracy even with ±45º SCH error of input reference input.

Black Input Signal –

Black 1: NTSC/PAL black burst output. Black 2,3: NTSC/PAL black burst output or tri-level HDTV sync.

Output Format –

Combination of the following:

1. NTSC/PAL black burst x3 (1 black burst is an independent, black burst x2 are distributed outputs).

2. NTSC/PAL black burst x2, HDTV tri-level sync x1 (all black burst and HDTV tri-level sync are independent).

3. NTSC/PAL black burst x1, HDTV tri-level sync x2 (HDTV tri-level sync x2 are distributed from the same source).

p-p

Option FP allows generation of full frame

test and custom patterns for the AVG7,AWVG7,

DVG7, and HDVG7 modules. Simple full frame

patterns are available on V3.1 (or higher

than V3.1) CD-ROM.
