• Display resolution up to 1280x1024

• Graphics overlay/underlay thanks to embedded mixer

• DVI 1.0 compliant graphics input interface

• Modular radar interface; adapts to any type of radar

• PPI, offset, sector, random and B-scan display modes

• Course-Up and North-Up display supported

• Proprietary “hole filling” process

• No load on host CPU or PCI bus

• RGB (analog) and DVI 1.0 compliant (digital) outputs

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.

one 8-bit input, one 7-bit and one
single-bit input, or one 6-bit and two
single-bit inputs (other configurations are

available, consult factory)

END-OF-SWEEP (EOS) PULSE

Disables processing of radar sweep until next trigger
Levels: single-ended or differential, 1-30 V peak
Input impedance: 75 ohms or Hi-Z if single-ended

100 ohms or Hi-Z if differential
Polarity: active low or high
Pulse width: 25 ns minimum

AZIMUTH INTERFACE

Interface: ACP/ARP
Type: binary (512-16384) ACP pulses/revolution
Levels: single-ended or differential, 1-30 V peak
Input Impedance: 75 ohms or Hi-Z if single-ended

100 ohms or Hi-Z if differential
Polarity: active low or high
Options: synchro, resolver, serial, and parallel

interfaces are supported; consult factory.

OPTIONAL US NAVY RADAR INTERFACES
All major interfaces, including Legacy Systems, are supported: RADDS,
AN/UYA-4, AN/UYQ-21.
