Scope of this Operation Manual
This is the operation manual for the System HD Distribution Amplifier module. It covers the modules ordered
under the following codes :
SHDSDA2S-S1 – Standard dual channel distribution amplifier with 4 outputs per channel
SHDSDA2E-S1 – Dual channel distribution amplifier with 4 outputs per channel and enhanced
reporting capabilities
SHDSDA2S and SHDSDA2E Dual Channel Distribution Amplifiers, Rear Panel View
Module Description
The Dual Channel HD-SDI Distribution Amplifier
provides up to four electrical HD-SDI outputs from
each of two independent HD-SDI bitstream inputs.
Each electrical high definition serial digital (HD-
SDI) bitstream is input into the distribution amplifier
main board via a 75ΩBNC connector on a rear
panel interface card. Each HD-SDI input signal is
then equalised and re-clocked before being split to
provide four electrical HD-SDI outputs via 75Ω
BNC connectors on the same interface card.
Two levels of monitoring sophistication are
available to the user. A standard operational level
is available on all boards, covering parameters
ranging from voltage supply status to the presence
of input signals. The optional enhanced monitoring
level provides a comprehensive analysis of the
incoming HD-SDI signals such as CRC error
detection, line standard and frame rate
identification.
Detailed performance information can be obtained
via the RollCall interface.
WARNING…
THE FRONT PANEL OF THE UNIT MUST NOT
BE OPENED BY THE OPERATOR. ACCESS IS
ONLY PERMITTED TO FULLY QUALIFIED
INSTALLATION ENGINEERS.
It is recommended you write the System HD Order
Code of the board this manual accompanied in the
table on the following page. This will allow easy
identification of the monitoring level of the main
board when referring to this manual at a later date.

Notes…
1. The dual channel HD-SDI distribution
amplifier (DA) is available with two levels of
monitoring sophistication. A standard
option which provides board level
information such as supply faults and
minimum incoming signal analysis. The
enhanced monitoring option adds a
comprehensive incoming signal analysis
capability, including the detection of CRC
errors and identification of the line
standard/frame rate of the signals being
distributed. Refer to the monitor option code
on page 2 to identify what monitoring level
is fitted to the DA board.
2. The interface card for the dual channel DA
contains ten BNC connectors of which all
ten are actually required for full operation
(two lots of one IN and four OUT). A single
channel eight output version of the DA card
is also available (order number SHD_SDA1-
SX) which provides eight outputs from a
signal input signal. A single channel DA
also has a 10 BNC rear interface card but
only nine BNC connectors are required
(one IN, eight OUT). The only difference
between the rear interface cards for the two
types of DA is in the backpanel labelling.
Mechanically these two different types of
rear interface card are completely
compatible with each other and can be
interchanged between the different types of
DA board. Refer to the interface card option
code on page 2 to identify what interface
card has been supplied with the dual
channel output DA main board.
CAUTION…
Confusion could arise if single/double channel
rear interface cards are assigned to the ‘wrong’
type of DA board. Though full functionality will
be maintained for both types of DA, the
difference in labelling could be misleading if all
such occurrences are not fully documented at
a system level.

nBias/EQ – The value in this field is a guide to
the strength of equalisation that is being
applied to the input signal for longer cable
runs. The lower the value, the less equalisation
is being employed. It is intended as a guide for
troubleshooting the system. It should be noted
that when an equalisation of 100% is shown, it
doesn’t necessarily mean that the maximum
input cable length has been reached. As soon
as CRC errors are being reported then the
input cable length should be decreased until an
error free signal can be received.
