Programmable TV Generator
Applications:
Research and Development=
The TSG1001 Programmable TV Generator and SDP1000 Signal Development Package provide a versatile system for definition and generation of commonly used and new television signals. Newly created signals or signals from the SDP1000 libraries can be quickly downloaded to the TSG1001 and output through analog and parallel digital outputs. The signals are generated either with an internal clock, or with a user-supplied clock. Downloaded signals are saved when the generator is off.
In addition to conventional static test signals, the TSG1001 provides moving signals for testing complex image-processing electronics such as bit rate reduction and motion-compensation equipment. The SDP1000 libraries contain simple patterns for basic testing needs. The TSG1001's programmable zone-plate generator provides complex patterns for advanced testing requirements; fixed- and swept-frequency horizontal, vertical, diagonal, and temporal patterns allow true multidimensional testing.
Test Signal Generator=
The TSG1001 provides signals in GBR, YPBPR, and composite NTSC formats. Precision digital signal generation ensures the accuracy and stability of the test signals. The high sampling rates and new Tektronix digital-to-analog converters provide 10-bit signals with 30-MHz bandwidth on all three channels. This allows full bandwidth testing of HDTV systems and extended bandwidth testing for NTSC and lower-bandwidth analog component systems. Two analog outputs are available for each channel. Parallel digital outputs are also provided to allow the TSG1001 to interface directly into digital systems that are clock rate compatible. The PSC1125 may be used to provide 1.485 GBps serial component test signals.
SDP1000 Signal Development Package=
The SDP1000 is a personal computer-based software tool for development of custom test signals for the TSG1001 Programmable Generator. The SDP1000 provides facilities for the editing of existing waveforms, creation of new waveforms, and the building of files needed to download signals from the personal computer to the generator.
Zone Plate Generator=
For the more complex testing needs, a fully programmable zone-plate generator is included. All horizontal, vertical, and temporal components may be set to a single frequency or swept over a user-defined frequency range and time interval. Factory preset zone-plate patterns include horizontal, vertical, and diagonal fixed-frequency patterns and horizontal, vertical, and circular sweep patterns. A temporal component may be added to any of the patterns. User-defined patterns may be easily programmed and saved in nonvolatile storage.
The two main parts of the SDP1000 are the waveform editor and the download file generator. The waveform editor provides command line menus and online help screens to simplify operation. The editor graphics provide a display of all or individual channels of the waveform, amplitude, and timing information, and the help function keys. The download file generator uses the test-signal files created by the waveform editor to build the files needed to download a test signal or group of test signals into the generator. Download files are provided for portions of and, in some cases, the entire library for all factory-provided test-signal libraries.
An external clock signal may be used in conjunction with the SDP1000 to define and generate test signals at arbitrary line and field rates. Note that the PSC1125 is supplied with a custom signal set not supported by the SDP1000.
