SMA-8018 Serial Monitoring Amplifier
1-2
Introduction
The SMA-8018 Component Monitoring Amplifier provides a convenient and cost effective solution to
signal distribution and picture monitoring requirements in serial component (4:2:2) systems. The
complete unit occupies only a single card slot in a standard Ross digital rack frame. Ten modules may be
mounted in the 2-RU frame.
This equipment includes a 6 or 7 output serial distribution amplifier with re-clocking, as well as an
exceptionally good cable equalizer for the serial input to give error-free performance with up to 1000 ft
(305 meters) of 8281 cable. A component digital to analog composite converter provides 1 or 2 composite
analog monitoring outputs. NTSC or PAL monitoring may be selected.
The analog monitoring outputs can be set to monochrome if desired. In the absence of an input signal, a
color black monitoring output is produced. Moving a jumper to the TEST position can produce a 75%
color bar pattern. Vertical interval blanking width is jumper selectable for either normal width or narrow
width to allow the passage of all vertical interval signals.
Of special interest is the inclusion of an adjustable analog cable equalizer for the monitoring signal. This
can be set to equalize 8281 type of output cables of up to 300 ft (90 meters) in length thus ensuring that
the monitoring signal is delivered to the destination without chroma loss.
Indicators are provided to confirm adequate serial input signal strength and monitoring errors.
