Genlockable Sync Pulse Generator - EZEEFAZE  SPG

Broadcast Video Genlockable Sync Pulse Generator.

Features

• EZEEFAZE is a genlockable sync pulse generator for broadcast studio use. As it is primarily designed to be locked to a master reference, considerable savings have been achieved, making it particularly cost effective.

    Applications

• It may be used in a studio environment to genlock equipment such as PAL coders, mixers and some chroma key units that normally require a full set of pulses.
• There are a number of computer graphic systems, VT clocks and character generators in use which lock to colour black but only provide colour subcarrier phasing adjustment. On these devices the output syncs emerge with a fixed delay relative to the input. Although the studio can be timed to this source, the situation becomes more complex when there is more than one such piece of equipment. In this instance an EZEEFAZE may be inserted between the station SPG and the device. The timing may then be adjusted on the EZEEFAZE.
• Another use for EZEEFAZE is to enable a source to be remotely phased. For example, if a telecine machine is to be shared between a number of studios via a switching matrix, care must be taken to ensure the source is correctly timed at its destination. By installing an EZEEFAZE at this point and feeding a locking signal back to the telecine, the source timing may then be conveniently adjusted.
• Although it was envisaged that EZEEFAZE would always be used as a slave to a station SPG, it is ideal for 'blacking' video cassettes.
• As an option for ENG applications 12V DC operation is available.
• Horizontal and subcarrier phase may be adjusted at the front panel or externally with DC controls. A preset store is available allowing instant recall of up to eight timings.

Outputs

EZEEFAZE provides outputs of mixed sync, mixed blanking, burst gate, PAL square wave, subcarrier, horizontal and vertical drives and three of colour black. The horizontal timings may be adjusted by ±4µS with respect to the input signal, and the subcarrier may be adjusted by at least 360°.

SCH Relationship

There is a school of thought that suggests that equipment should not have separate H and SC phase adjustments. This may well be valid. However, as the majority of studio equipment encountered does have separate adjustment, EZEEFAZE also has both, thus enabling corrections to be made to 'incorrectly' SCH adjusted equipment. If the EZEEFAZE is to be used as a free-standing source with 1" VT machines, an internal adjustment of SCH is available to order.

Ordering Information

The EZEEFAZE is available in the following versions: Type 2001 has pulse outputs only, and Type 2002 has pulse outputs and colour black. Each version is available in PAL or NTSC, rack mount or portable.
