1-4. BROAD SCAN INFORMATION
Broad Scan by Analog Way is a Broadcast and Professional Computer to Video Scan Converter. Fitted with Digital
DVI and Analog RGB input, it converts Workstation, PC or Mac graphic images up to1600x1200 @ 60Hz (1920x1200
RB) into NTSC or PAL video. Each computer input has its own monitor loop through output for the connection of a
control display.
Broad Scan features a powerful broadcast Genlock through a NTSC or PAL Black Burst. Genlock input is fitted with a
loop through output allowing to daisy chain devices. The user can adjust phase and subcarrier delay according to a
specific installation requirements. All Genlock timings meet broadcast ITU/SMPTE standards.
Broad Scan output formats are:
• NTSC – 525i @ 60 & 59.94 Hz – 15.735 kHz - ITU / RS170-A
• PAL– 625i @ 50 Hz – 15.625 kHz – CCIR
Broad Scan outputs different signals at the same time in one selected output format NTSC or PAL: one YUV or RGB,
one S.Video and one Composite Video signals are available simultaneously.
Broad Scan also outputs Luma Key signal. The Luma key signal comes in the same format as the output and perfectly
timed. In addition, a Frame Lock output allows synchronizing an external device frame rate such as a graphic card.
Broad Scan features real time conversion with high performance Image Processing. User adjustments offer an Anti-
Flicker filter to significantly reduce flickering of the interlaced TV outputs, as well as 2D Sharpness, RGB level and
Black level. It converts single wire computer type signal into black and white video image just by setting a menu. The
state of the art high speed hardware FPGA allows aspect ratio control and a wide linear or non linear zoom capability up
to1000%. In addition, a new highlighted “zoom finder” is provided to preview the actual part of the picture to be
zoomed (H, V and H&V simultaneously).
Broad Scan is designed to be User Friendly thanks to many direct access functions such as Freeze, Black, Under/Over
scan, Aspect Ratio, Zoom position and size. It also has easy to use and efficient menus on a clear bright blue LCD
screen. LCD continuously displays Input and Output status during operation.
Broad Scan includes Computer input format memory: Up to 16 user presets are stored in the device corresponding to 16
different input for-mats. The exact adjustments of the frequently used formats are instantly recalled which makes the
Broad Scan ideal and very useful for multi-computer applications or rental.

1-6. INSTALLATION
IMPORTANT: Please read all the safety instructions (pages 2 to 4) before starting.
• Table Top Mounting The devices can be used directly on a table: they are equipped with 4 plastic feet.
• Rack Mounting:
The devices are compatibles with a 19" enclosure. To install the device into a 19” rack: Attach
the device to the rack by using 4 screws in the front panel holes (screws are not included).
Connect all of the cables to the devices and attach them to the rack with some tie wraps.
IMPORTANT:
• The openings in the rear and side panels are for cooling. Do not cover these openings.
• Be sure that no weight is added onto the device in excess of 2 kg (4.4 lbs.).
• The maximum ambient operating temperature must not exceed 40°C (104°F).
• The rack and all mounted equipment in it must be reliably grounded to national and
local electrical codes.
