The Link Electronics IEC-721 Master BB & CB Generator with Genlock automatically toggles between NTSC or PAL in the Genlock mode depending on the reference input, whereas it defaults to the selected standard in the free run mode. Using FPGA (Field-programmable Gate Array) technology, the generator offers optimum performance for color bar and black burst as well as flash pattern.
Equipped with 10-bit processing, the IEC-721 generator may be set up for flashing a small box on and off on the video output to confirm frame synchronizer freeze for a remote satellite setup. The IEC-721 generator comes with 2 pairs of independently selectable outputs and the timing range for each output (vertical and horizontal) is infinite.
The front panel, 8-character LED display shows the function under adjustment, whereas the 2 push-button switches are for the Escape and Enter functions. Adjustments can be easily made to the color bar / black burst generator using the front panel control buttons and the rotary encoder.
For timing purposes, the IEC-721 generator receives a reference black burst in the Genlock mode. The generator can also operate as a stand-alone unit with an inactive looping reference in the free run mode. Infinite Genlock vertical and horizontal timing range is suitable for timing the signal into the studio facility as the 2 outputs can be easily adjusted over the horizontal and vertical timing range. VCXO (Voltage-controlled Crystal Oscillator) offers high stability and provides the accuracy necessary for meeting demanding requirements.
Specifically designed for use in RS-189-A (formally 170A) analog applications in both 525/60 and 625/50 systems, the IEC-721 generator is compatible with the EIA RS-189A and the SMPTE encoded color bar standard.
