The LEI-523 by Link Electronics™ is a series of broadcast High Definition and Standard Definition sync generator with HD component test patterns, providing the user with high quality, low cost system to produce sync and HD Test Patterns. The LEI-523 can be use to gen-lock to other syncs or as a stand alone unit (Master Sync Generator).

This unit is a multi-format generator that can be used where various HD signals are required. Tri-level sync is on all analog component outputs, RGB or YUV. Sync output can be selected as Bi-level (black burst) or Tri-level. All outputs are in time with each other even as a SD and HD sync generator.

There are a total of thirty test signals available, including SMPTE, EIA and Full Field Bars. There are twenty three different HD formats available plus NTSC or PAL black burst. It also has a unit identification that can be enabled to uniquely identify up to 100 different units. It also has the ability to alternate (flip) the pattern to black making the video active so that one can see if the video has been frozen when going thru other equipment.

The LEI-523 gen-lock’s with a pair of looping BNC connectors on the rear panel the reference input can be either Tri-level (HD) or Bi-level (SD) sync. The gen-lock provides adjustments of infinite horizontal and vertical Timing and gen-lock indication.

The Link Electronics product design, performance and reliability are reflected in the New-Generation of Link Electronics products. A pair of lighted push buttons and an optical rotary encoder changes and selects between various menus. User friendly operation is a key concept of this instrument.
