PROGRAMMABLE ZONE PLATE
This option adds a range of pre-programmed zone plate
patterns along with user defined controls over several
parameters which can be saved to custom buffers.
Moving zone plates provide a very useful ‘dynamic’
pattern for testing a range of video processing equipment.
Spacial and temporal controls are particularly useful for
testing up/down converters, image scalers
and applications which compress signals. Frequency
sweep testing using the zone plate is particularly useful in
determining the usable bandwidth of the system. All
formats are supported using this option including 16:9 and
4:3 aspects, each pattern automatically scales for the
chosen format.
