Chapter 1: Introduction

Product Description

The VCA / VDA / VEA6800

+

is an analog video distribution amplifier

set in the new 6800+ family.
These DAs feature high video performance, low cost, and remote
control.

Typical Broadcast and Production Applications

The VCA / VDA / VEA6800

+

distribution amplifier can be used in

broadcast, cable, production, educational, and auditorium applications
where a low cost method of distributing analog video signals is
required.

Main Features

VCA6800

+

The VCA6800

+

is an analog video clamping and equalizing

distribution amplifier. Other VCA6800

+

features include the following:

•

One differential input

•

Eight outputs with dual slots back module, four outputs with single
slot back module when installed in FR6802

+

X(F) frames; eight

outputs when installed in FR6802

+

DM(F) frames

•

AC and DC input coupling selectable

•

Looping and internal terminating selectable with dual slot back
module, internal terminating with single slot back module with
FR6802

+

X(F) frames; looping or internal terminating selectable

with FR6802

+

DM(F) frames (see

Figure 2-2 on page 18

for

instructions on setting this jumper)

•

± 3 dB gain adjustable range

•

>50 MHz bandwidth

•

Continuous cable equalizing up to 984 ft (300 m) Belden 8281
cable, or equivalent

•

Back porch clamp with selectable soft, hard and non-clamp modes
Gain and EQ setting components are installed on a removable
submodule; in the event of failure on the DA module, a replacement
can be quickly inserted with the original submodule to keep the
previous setting
