Information

TSG-271 PAL Television Generator The TSG-271 generates PAL test and sync pulse signals at unmatched price for performance. Featuring a unique digital architecture and innovative technology, the TSG-271 offers: • Precise 12-bit digitally derived test signals. • SCH phase accuracy, guaranteed by use of a single DAC. • Stable internal reference, ideal for master sync operation. • Reliable slave operation through use of digital genlock. • Separate front panel genlock and sync timing controls. Test Signals The TSG-271 uses digital signal generation and a precision 12-bit DAC to ensure test signal accuracy and long-term stability. Digital generation of the composite PAL signal, without analogue modulators, allows use of a single DAC to inherently match chrominance and luminance timing. This ensures accurate SCH phasing. With the TSG-271’s simple front panel controls you can select the following test signals: • Colour Bars • Pluge • Convergence • Pulse & Bar with Window • Field Square Wave • Multiburst • Multipulse • Staircase • Modulated Staircase • Ramp • Modulated Ramp • Full Field ITS • Flat Fields • SinX/X • Line Sweep • APL and Bounce Colour bars can be set to either 75% or 100% amplitude. Narrow blanking on colour bars helps verify proper blanking throughout your system. Composite video outputs, both test signal and black burst, include a white pulse inserted on line 7 of field 1 for colour-frame identification Sync Generator with Digital Genlock The TSG-271 Sync Generator’s stable colour standard and unique digital genlock make it ideal for either master Generator or slave operation. All outputs are correctly SCH phased, even if the TSG-271 is locked to an improperly SCH phased reference input. The digital genlock calculates sync timing and subcarrier phase to properly identify colour framing of the reference signal. The TSG-271 automatically senses composite video reference input and, in the absence of a reference input signal, automatically switches to its own internal reference. With its constant temperature oven, this high stability crystal Oscillator ensures long-term frequency stability. Flexible Timing Controls Front panel controls allow phasing of all outputs relative to the genlock source. In addition, a separate set of timing controls move the pulse outputs relative to the black burst and test signal outputs. This simplifies system timing and eliminates delay lines. All timing settings are stored in non-volatile memory to prevent loss in the event of a power failure. A front panel lockout feature prevents inadvertent changes to the front panel timing controls.
