Preface
Manual Conventions
This manual uses certain conventions that you should become familiar with.
Some sections of the manual contain procedures for you to perform. To keep those instructions clear and consistent, this manual uses the following conventions:
Names of front panel controls and menus appear in the same case (initial capitals, all uppercase, etc.) in the manual as is used on the TG700 front panel and menus.
Instruction steps are numbered unless there is only one step.
Bold text refers to specific interface elements that you are instructed to select, click, or clear.
Example: Press the ENTER button to access the PRESET submenu.
Italic text refers to document names or sections. Italics are also used in NOTES, CAUTIONS, and WARNINGS.
Example: The Diagrams section, beginning on page 9-1, includes a block diagram and an interconnect diagram.
Modules Throughout this manual, any replaceable component, assembly, or part of the TG700 is referred to generically as a module. In general, a module is an assembly (like a circuit board), rather than a component (like a resistor or an integrated circuit). Sometimes a single component is a module. For example, the chassis of the TG700 is a module.
Safety Symbols and terms related to safety appear in the Safety Summary near the beginning of this manual.
Finding Other Information
Other documentation for the TG700 includes:
The TG700 TV Signal Generator Platform User Manual (Tektronix part number 070-A799-XX) contains a tutorial to quickly describe how to operate the TG700. It also includes an in-depth discussion on how to more completely use the TG700 features.

TG700 TV Signal Generator Platform Service Manual |
Introduction
This manual contains information needed to properly service the TG700 TV Signal Generator Platform, as well as general information critical to safe and effective servicing.
To prevent personal injury or damage to the TG700, consider the following before attempting service:
The procedures in this manual should be performed only by a qualified service person.
Read the General Safety Summary and the Service Safety Summary, beginning on page v.r
Read Installation in section 2, Operating Information.
When using this manual for servicing be sure to follow all warnings, cautions, and notes.
Performance Check Interval
Generally, the performance check described in section 4, Performance Verification, should be done every 12 months. In addition, a performance check is recommended after module replacement.
If the TG700 does not meet performance criteria, repair is necessary.
Strategy for Servicing
Throughout this manual, the term ªmoduleº refers to any field-replaceable component, assembly, or part of the TG700.
This manual contains all the information needed for periodic maintenance of the TG700 (Examples of such information are procedures for checking performance).
Further, it contains all information for corrective maintenance down to the module level. To isolate a failure to a module, use the fault isolation procedures found in Troubleshooting, part of section 6, Maintenance. To remove and replace any failed module, follow the instructions in Removal and Installation Procedures, also part of section 6. After isolating a faulty module, replace it with a fully-tested module obtained from the factory. Section 10, Mechanical Parts List, contains part number and ordering information for all replaceable modules.

The TG700 TV Signal Generator Platform is a multiformat TV signal generator platform supporting both analog and digital video standards. The TG700 consists of a mainframe and up to four plug-in modules. The modules are either signal generators or they provide special functions, such as genlock capability.
Key Features The TG700 and the available modules provide the following features:
Simultaneous generation of HDTV/SDTV multi format synchronized signal and test signal
Modular architecture with up to four generators or special function modules
Analog genlock function dealing with NTSC or PAL black burst signal, HDTV trilevel sync signal, and CW signals (AGL7).
Independent setting of amplitudes, frequencies, and audio clicks of 16 channel embedded audio signal (DVG7 and HDVG7)
Circle, logo, and text overlays on test signals (DVG7 and HDVG7)
Moving picture generation function by scrolling the active area of the signal (DVG7 and HDVG7)
Reference generator performance level
Ethernet interface for remote control and downloading various files such as signal files, logo files, and preset files
A signal library and various application software are included in the attachment
CD-ROM to execute the following operations:
Upload and download files such as signal files, logo files, and preset files
Download the signals from the signal library to the TG700
Create a logo (logo file) to be inserted into the test signal
Create a frame picture file using the generation of a picture or test pattern
