Link Electronics 812-OP/G Analog Test Signal Generator

While the SPG-812 Analog Test Signal Generator, also known as 812AT or OP/G, is a crucial component of the GenFlex product lineup, it stands out for its advanced features and reliable performance. This high-quality test set module from Link Electronics offers the flexibility to choose from sixteen different video test patterns. These selections can be made either directly from the front panel switch or remotely via the SPG-812TRC control unit.

The SPG-812 Analog Test Signal Generator is capable of producing patterns in four distinct formats: Composite video plus a Y/C pair, SMPTE Component video: Y-Pr-Pb, Red, Green and Blue (RGB), and Green + Sync, Blue and Red. All patterns are created at a 10-bit resolution, utilizing high-performance hybrid post-filters with integrated output amplifiers. The device supports both NTSC and PAL video standards, making it a versatile tool for a wide range of electronic testing needs.

When genlocking to incoming video, the SPG-812 chassis can accommodate either an analog (812AG or OP/C) or a digital genlock module (812DG or OP/D) in the bottom slot adjacent to the power supply. The Genlock module provides the necessary timing pulses on the motherboard buss, enabling each subsequent module to lock to a single reference.

The SPG-812 Analog Test Signal Generator offers sophisticated "infinite window" timing of horizontal and vertical, as well as 360-degree subcarrier phasing. All timing information is securely stored in battery backup RAM within the unit's onboard microcontroller. This durable test set module can be installed in any slot within the SPG-812 chassis, except for the slot reserved for the audio module.

The 812-OP/G plug-in module provides 16 analog test signals, including 100% color bars, SMPTE color bars, 5-Step modulated stair step, and more. It uses a single 2-bit mechanical encoder to control all module functions, including system timing and pattern selection. An eight-character alpha-numeric display offers a user-friendly menu of options for each module parameter.

In conclusion, the SPG-812 Analog Test Signal Generator is a reliable, advanced, and user-friendly solution for generating test signals in the electronics industry. Its high-quality construction and sophisticated features make it a standout choice for professionals seeking a dependable test pattern generator.
