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.

•Six or seven serial digital outputs
•One or two NTSC or PAL analog monitoring outputs
•Excellent chroma modulation accuracy
•Cable equalization for monitor outputs

Installation
1) Cables
Connect the input and output cables. The input is internally terminated in 75 ohms. The BNC
connectors on the rear of the frame are marked for distribution amplifiers having eight outputs.
However, in the case of the SMA-8018, there are six or seven outputs of serial digital and one or
two analog composite video outputs. It is not necessary to terminate unused outputs.
Refer to the following.
2) Set Jumpers
Set the jumper plugs to determine the nature of the analog output signal.
SYSTEM (JP2) PAL For 625 line systems
NTSC For 525 line systems
CHROMA (JP2) ON The normal position
OFF Used to output luminance only for the best picture on
a monochrome monitor.

V BLANK (JP2) NORMAL Deletes all vertical interval information signals
(20-line blanking).
SHORT Passes all vertical interval signals occurring after the
post equalizing pulses. If setup is ON, the signal will
be non-standard because setup will be applied to the
vertical interval.
SETUP (JP2) ON For NTSC in North America
OFF For all other systems
MODE (JP2) NORMAL Normal operation
TEST Produces an analog color bar output. This may be
useful for monitor alignment.
OUT 7 (JP3) D Output 7 will have a serial digital output.
AOutput 7 will have a composite analog output.
FAULT REPORT (JP1)
DISABLE SMPTE 269M Fault Report is disabled.
ENABLE SMPTE 269M Fault Report is enabled.
3) Final User Setup
Set the analog output EQUALIZATION (RV2) adjustment for the cable length used between the
amplifier and destination. Plug the board into the frame and apply power.
The equalization control is calibrated for 8281 cable. For other types of cable, put the board on
the extender, apply a D1 color bar signal and using a scope, set the EQUALIZATION adjustment
for correct chroma level at the destination.
4) Check that the green INPUT STATUS LED is on and the MONITOR ERROR LED is off,
indicating a suitable input signal. The amplifier should be functioning properly.

Operation
The only customer-operated controls are GAIN (RV4) and EQ (RV2) for the analog video output.
The GAIN control has been factory-adjusted for correct output level and should not need adjustment in
the field. The front edge of the module has several LED indicators, which show the current status of the
amplifier. The meaning of the LED indicators when lit is as follows:
INPUT STATUS
Green When lit means that the input signal is suitable for achieving error-free performance.
That is, it is within the capability of the cable equalizer and re-clocking circuit to
restore the signal.
Red This indicates that the input signal is too low or absent. In some circumstances the
signal may still be restored correctly but the circuits will be working close to the limit
of their capability and reliability cannot be assured.
MONITOR ERROR
This indicator identifies if there is a problem with the input signal or in the analog conversion
section of the card. There are three states for this indication.
STEADY RED The signal is present, but not the proper format (e.g. Composite
Digital). (During this condition, the SMA 8018 provides an
internally generated black burst signal to the analog outputs.)
FLASHING RED There is no input signal.
50% duty cycle (During this condition the SMA 8018 provides an internally
generated black burst signal to the analog outputs.)
FLASHING RED The monitoring amp is in the "TEST" mode.
10% duty cycle (In this mode the SMA 8018 provides an internally generated
color bar signal to the analog outputs.)

Fault Reporting Capability
Fault reporting in the SMPTE 269M standard is available on this card. This is a simple system, which can
indicate that one, or more of the modules in the rack frame has encountered a fault or abnormal condition.
Each rack frame has a "telco" connector, which can be connected to an external "contact closure" type of
alarm system. A customer-devised system of lights can be used to trace a fault to a rack cabinet, rack
frame, then a particular card. For more information on designing such a system, refer to SMPTE
document ANSI/SMPTE 269M - 1994.
If the FAULT REPORT jumper (JP1) is enabled, the output will be a steady low signal if there is no
power in the module. The output will pulse at a field rate if the input signal is very low or absent. In all
other situations, the output is open (high impedance).
All frame modules having fault reporting capability are connected in parallel to the "telco" connector.
Maintenance and Repair
Routine maintenance is not required. If the module does not appear to be working properly, return it to
Ross Video Ltd. for repair. All Ross digital distribution products are covered by a generous 5-year
warranty and will be repaired without charge for materials or labor in this period. See "Ross Gear
Terminal Equipment - Warranty and Repair Policy" in this manual.
