Analog Generator

TSG170A

The new matrix is composed of FCC color bars, 50% flat field, NTC 7 combination and composite, (Sin x)x, red field, and chroma frequency response.

Master Sync Generator with Digital Genlock

The TSG170A sync generator's stable color standard and unique digital genlock make it ideal for either master generator or slave operation. All outputs are correctly SCH phased, even if the TSG170A is locked to an improperly SCH-phased reference input. The digital genlock calculates sync timing and subcarrier phase to properly identify color framing of the input reference signal. The TSG170A automatically senses composite video or 3.58-MHz subcarrier reference inputs and, in the absence of a reference input signal, automatically switches to its own internal reference. This high-stability crystal oscillator, with its constant temperature oven, ensures long-term frequency stability.

System Timing Control

Front-panel controls are provided for phasing of all outputs relative to the genlock source. In addition, a separate set of timing controls is provided to move the pulse and subcarrier outputs relative to the black-burst and test-signal outputs. This simplifies system timing and eliminates delay lines. Up to eight genlock and sync timing settings may be stored in nonvolatile memory to prevent loss in the event of a power failure. The timing presets may be recalled through the remote control port. A front-panel lockout feature prevents inadvertent changes to the front-panel timing controls.

Flexible Pulse Output

The TSG170A has eight sync generator outputs; four fixed and fournmental
