Ensemble Designs 5400 Dual Sync Generator and Test Signal Generator with HD Tri-Level Sync - Manual (Page 10)

Making Reference Choices
Each generator can be independently set to operate either as a Master Sync Generator
(using an internal precision frequency reference), or genlocked to an external reference
source of either composite video or a 10 MHz sine or square wave. In addition, the
secondary generator can be set to lock to the primary generator in tracking mode. These
choices are made using the Pri and Sec Source controls in the Primary and Secondary
menus. Refer to the block diagram below.
When a generator is set to be genlocked (by selecting Config Ref in the Pri or Sec
Source menu), a further selection must be made to configure the module to use either its
external genlock BNC (labeled Genlock/10 Mhz In on the module backplane) or the
Master Frame Reference which is distributed through the Avenue frame backplane. This
choice is made in the Config menu and provides the configured reference for both genera-
tors. The module will accept analog composite NTSC (525) or PAL (625), or a 10 MHz sine
or square wave as an external genlock signal.
In order to provide the ultimate in flexibility, the television line standard output for each
generator can then be set to either 525/60 Hz or 625/50 Hz. These output choices are
possible even when the generators are locked to a genlock input in a different standard.
