General Safety
Avoiding Personal Injury
This instrument is designed for use by qualified personnel only.
No user serviceable parts are provided. Units should be returned to your local
PHABRIX agent for servicing.
The Operator should NOT remove the case from the unit.
Do not spill any liquid onto the unit or its power adaptor.
Do not look directly into the fibre optic connections of cable as this may cause
permanent damage to the eye.
Power Supply
Make sure that the unit is connected to the correct power supply voltage. A power supply
adaptor is supplied with the unit which may be connected to any AC power supply between
100 and 240VAC at 50-60Hz. Only the supplied power adaptor should be used with the

Installation Environment
Operating Temperature
The unit should only be operated between 0 and 40 °Centigrade. If the unit is
operated at a higher temperature there is a possibility of a fire hazard. If the
temperature is changed rapidly from a cold environment to a hot environment,
moisture can be created internally which can cause malfunction or damage the
unit. Allow the unit to sit for 30 minutes without power applied to reduce any
possibility of condensation. If the temperature rises above 60°Centigrade a
warning dialog will be given. If the temperature rises above 65°Centigrade the
unit will be turned OFF. Under both conditions, an event will be added to the
event log to show what happened.
Input/Output Terminals
Do not connect the input or output BNC connectors to external power as this can damage the
internal circuitry and cause the unit to work incorrectly.
The BNC connectors fitted on this unit are 75Ω type which are not compatible with 50Ω plugs.
The use of 50Ω plugs will permanently damage the connectors on the unit. The
use of 50Ω plugs is considered to be misuse of the equipment and will therefore
invalidate the unit’s warranty.
SFP Cage
When the SFP cage is fitted, either an SFP or a bung must be fitted in the SFP
cage at all times to prevent the SxTAG overheating.
When Not In Use
Disconnect the unit from the power supply and AC power source when not in use.
Maintenance
Wipe the case, and knobs gently with a soft cloth, lightly dampened with a neutral cleaning
agent. A screen cleaning cloth may be used to clean the LCD. Do not apply force to the LCD
when cleaning or it may be damaged.
Remove the power supply from the unit and turn OFF before cleaning. Do not
allow any water or other liquid to enter the unit while cleaning.

SxTAG Instrument
Overview
Configured as an entry level portable analyser, the TAG can be easily upgraded using a range of
software options to provide a sophisticated instrument for testing broadcast infrastructures.
The PHABRIX® TAG has been created to incorporate new interfaces that appeal to customers
looking for a cost effective entry into professional test and measurement.
The PHABRIX® TAG includes support for SD-SDI and HD-SDI as standard with the option to
upgrade to 3G-SDI (Level A and Level B).
Composite analysis and generation has been incorporated to support those regions making the
transition between analogue and digital television.
An SFP cage has been integrated into the design principally for optical infrastructure testing,
however, the cage will support a wider range of SFPs as they become available. Composite
locking reference generation and input reference waveform analysis have also been included.
For audio support the PHABRIX® TAG provides a D15 breakout connector providing both
balanced analogue and AES input/output. AES waveform display allows a visual check of levels
and reference lock. Advanced audio features including Dolby® E, Dolby® Digital and Dolby®
Digital Plus are supported allowing TAG to be considered as a replacement for the discontinued
Dolby® DM100.
Internal Speaker Menu Buttons Cursor/OK Buttons
Power On/Off
Turning on and off the instrument
To turn on your PHABRIX SxTAG Instrument press the red button at the top right hand corner
of the front panel.
Once the system has started, pressing the button again will turn it off. If for some reason the
instrument stops responding, pressing and holding the button for a few seconds will turn it off.
The unit is battery operated and the battery should last for between 3 and 6 hours dependent
on which video standard is being used and whether the input and outputs are active. If the
unit is turned ON and the battery is almost discharged, it will turn itself OFF. If the battery
level starts to get too low for operation a dialogue will be displayed prompting the user to turn
off the unit. The current settings will also be saved. The unit should then be connected to the
power supply unit as soon as possible to recharge the battery. The battery should be fully
charged in about 4 hours. The battery will charge faster if the unit is turned off while charging.

analyzer is connected to the input. If the analyzer is set to monitor the output, the input
standard will be shown in brown.
The output standard will be shown in red if the instrument is generating errors. The output
standard will show OFF if the generator output is Off.
Using the Menus
The Main menu is the top level menu from which all other menus are selected on the SxTAG
instrument. The main menus are:
Generator allowing the unit to be locked to an external reference and providing a
fully populated Composite, SD-SDI, HD-SDI and Fibre video test pattern
generator and audio tone generator if the Generator option is installed.
Analyser allows the selected Composite, SDI or Fibre input signal to be analysed in
the form of a Picture, Waveform monitor and Vectorscope.
Sig Info allows detailed signal information about the video and audio status for the
SDI or Fibre video input source to be displayed.
Audio gives access to the Audio Meters and Audio Status displays allowing the
levels of the embedded SDI audio, AES audio and analogue audio to be
displayed.
System allows the setup of system wide settings including memories, date/time and
software.
Logging selects the logging page to view and setup the error logging system.

Description
SxTAG Software Options
Overview
The SxTAG instrument has a range of software options that can enhance its functionality for
specific applications.
The Generator option (PHSXT-GEN) allows
the creation of video test signals for
analogue composite video, SD-SDI and HD-
SDI video as standard. 3G-SDI, 2K SDI and
Fibre video functionality can be purchased
as additional options. The Generator option
also allows the generation of both analogue
and digital audio test tones and allows the
unit to be locked to an external locking
reference.
SDI data stream analysis
The SDI analysis option (PHSXOSD)
provides the engineer with a detailed view
of the data words contained within the
SDI stream. This allows the analysis of
complex faults and is particularly useful
when determining compatibility issues
between equipment and when debugging
new product developments particularly in a
R&D environment. Detail within the active
SDI stream can be viewed with continuous
update.
The SDI Analysis option provides the following functional areas:
Grid displays the SDI data in the form of an array.
Stream allows the SDI continuous data stream to be viewed.
Component allows the video components to be displayed in separate columns.
Splt allows the video components to be display individually.
Ancillary Data allows the user to capture whole Ancillary data packets identified by their
data id (DID).
Ancillary Status allows additional ‘user defined’ selections with the appropriate DID or SDID
code.
Access to the SDI analysis functionality is via the Analyser - Signal Data menu. See the
“Analyser - Signal Data” section in chapter 2 for full details.

Description
Command scripts with print report
The Command Script option (PHSXOS)
allows a series of predefined actions to be
run through within the PHABRIX Sx using a
script stored in internal memory.
The command scripts option can be used
to automatically step through a sequence
of instrument states, controlling the
generator, analyser and logging functions.
If required the instrument will prompt the
user before going onto a subsequent state.
Applications include repeated test sequences as required by manufacturer Test Departments,
R&D Departments, Systems Integrators and Commissioning/Support Engineers.
A script requires a set of memories to configure the unit and then a script file which recalls
those memories and specifies times and actions for each step. The process of creating a
command script requires these two files to activate the sequence.
Additionally a script can be created as a simple text file on a PC and then transferred to the
unit via Ethernet and recalled at any time. A large number of named scripts and memories may
coexist within the instruments store to be recalled as required.
Access to the Command Scripts functionality is the “System” - “Command Scripts” menu. See
chapter 2 for details.
Enhanced remote control
The Enhanced remote control option
(PHSXOR) gives users full remote control
of the unit via TCP/IP Sockets to allow
any aspect of the unit to be modified or
queried.
This allows complex applications to be
created to perform test and measurement
functions such as automated testing of
routers or other broadcast equipment.
PHABRIX products act as a server and listen on a port waiting for incoming requests from
clients such as a PC. Using this method of communication the Sx range can provide a variety
of information to the control device it is connected to and be controlled in specified areas of
the product using the command details included. All visual controls on the product have an
associated command.
Messages may be sent to ‘set’ or ‘get’ data from a command ie if you ‘set’ a value the unit
will be configured accordingly and a reply returned and if you ‘get’ a value from the PHABRIX
unit it will reply with that value. All messages are acknowledged to increase the security of the
interface ie closed loop communication.
The control structure can be selected as Passive or Active. Passive control allows simple remote
control where the host PC is in control and sends commands when it wants to change data or
get information. It is this method which is the most popular use for remote control.
