Functional Description
UCD-422 units consist of a multimedia signal input stage, an internal pattern generator, a
control stage with on-board frame buffer and a PC interface stage. In the Input Stage the
signal is conditioned and converted to desired format. The Interface and Control stages are
either passing the captured data directly to the USB interface or storing it to the frame
buffer. The internal pattern generator is able to source a signal for testing sink and branch
units. The Interface & Control stages are receiving instructions from the host PC to
configure and control the functionality of the unit.
