Barco’s RSC1520DV is a high-performance Commercial-Off-TheShelf PCI Radar Scan Converter. The board receives radar video,
trigger and azimuth signals from a radar unit and processes
these signals to generate a high-resolution display in real-time.
Dedicated digital signal processing circuits provide extremely
high quality output without loading the host CPU or PCI bus.
The embedded radar/graphics mixer enables highperformance graphics overlay and underlay capability. A DVI
1.0 compliant graphics input interface provides compatibility
with a growing number of low-cost graphics adapters, which
allows for the configuration of cost-effective, high-performance
PCI-based radar display systems.
The RSC1520DV is supplied with a Windows® NT/2000 device
driver, offering full control of all radar scan converter functions
through the user application.
