  • Page 23 Theory of Operation The WVR8200 and WVR8300 are modular waveform rasterizers. They can be configured, with options, to accept Analog Composite inputs. Audio options can add inputs for digital only or analog audio capability. All models use an external DVI-I monitor for the display. All models also have outputs to drive serial digital and analog picture monitors.
