A
EXTRON’s PA 250 is a long line peaking amplifier and sync condi-
tioner which is capable of driving RGB Video Signals up to 1000 feet.
As an inexpensive alternative to fiber optics with an RGB Video
Bandwidth of 250 MHz (-3dB), the PA 250 is designed for systems
requiring long cable runs where signal quality is a premium concern. By
simply connecting the PA 250 at the origin of the signal, a clean, strong
signal can be maintained throughout the cable run with performance
enhancing features to fit any application. Including features such as
Sync Stripping, Sync Combining and Image Sharpness Control, the PA
250 can replace what could take up to four other products to accomplish.

n 250 MHz RGB Video Bandwidth
n Peaking - This is similar to the sharpness control on a T.V. It is
used to manipulate the video signal to provide a cleaner, sharper
image. The peaking adjustment is actually compensating for mid
and high frequency RGB Video Bandwidth response in data
monitors and projectors, and for signal loss due to cable capacitance.
n Boost Control - Selects the percentage of maximum signal boosting
capability. The Boost control allows for signal “driving” of up to
1000 feet depending on input signal frequency. Standard 15.75 kHz
Video (RGB) signals can be driven up to 1000 feet with VGA/MAC
and other mid frequency signals capable of going up to 600 feet.
The PA 1 250 can even drive SGI 60-100 kHz signals up to 350 feet
with good quality cable.
n Level Control - Increases signal to a maximum level of 1.4 Volts.
n Sync Combining - Combines horizontal and vertical sync signals
into a composite sync channel.
n Sync Seperation - Seperates composite sync into seperate horizontal
and vertical sync.

n Auto Sync Stripping - Strips sync from the red,green and blue
channels. The sync can be added back onto the green channel if
desired via a rear panel dip switch.
n 15-150 kHz horizontal frequency range
n BNC connectors - For ease of system integration.
n Rack Mountable - 1U, 1/2 rack width.
