Scope of this Operation Manual

This is the operation manual for the System HD Single Channel Distribution Amplifier Module. It covers the

modules ordered under the following codes :

SHDSDA1S-S1 – Standard 8 output distribution amplifier with basic reporting.

SHDSDA1E-S1 – 8 output distribution amplifier with enhanced reporting

SHDSDA1S-S1 and SHDSDA1E-S1 Distribution Amplifier, Rear Panel View

Module Description

The Eight Output HD-SDI Distribution Amplifier

provides eight reclocked HD-SDI outputs from a

single HD-SDI input.

The 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. The HD-SDI input signal is then

equalised and re-clocked before being split to

provide eight identical coaxial HD-SDI outputs for

the user via 75ΩBNC connectors on the backpanel

of the interface card.

Detailed performance information can be obtained

via the RollCall interface.

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 an input signal. The optional enhanced

monitoring level provides a comprehensive

analysis of the incoming HD-SDI signal such as

CRC error detection, line standard and frame rate

identification.

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 that a record is made of the

System HD Order Code for the module 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 eight output 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 signal 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 single channel

eight output DA contains ten BNC

connectors (see following page for

drawing) of which only nine are actually

required for full operation (one IN, eight

OUT), the middle BNC not being used. A

dual channel version of the DA card is also

available (order number SHD_SDA2x S2)

which contains two separate four output

amplifiers. A dual channel DA also has a 10

BNC rear interface card (two lots of 1 IN,

four 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 eight 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.

The high definition serial digital electrical output is

available from eight 75ΩBNC connectors, each

providing identical outputs. These connectors are

shown below and are labelled H2, H3, H4 H5, H6,

H7,H8 and H9.

Note…

The connector at the middle of the backpanel is not

used with this main board but could be used if a

dual channel main board is inserted (see Technical

Profile, OPTIONS).

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.
