OPERATION
TURNING THE UNIT ON OR OFF
To turn on your PHABRIX Sx press the red button at the top right hand side of the unit.
Once the system has started, pressing the button again will turn it off. If for some reason the unit 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 dialog 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.
UNIT STATUS LINE
The top line of the menus shows the unit status and includes the Input Video status, Genlock status, battery status and current time. If
the unit is being powered by the AC adaptor, the battery status will not be shown. If a command script is being run, this is shown on the
top line to the left of the time as “Script”. A red “Log” is shown on the status line if there are any events in the event log.
If a 3G video standard is selected the video standard display will be shown as 3GA if it is a 3G-Level A standard, 3GB if it is a 3G-Level B
dual link standard, 3G2 if it is a 3G-level B dual stream (two patterns) standard or DL if it is a dual link output (SxD only).
The input video standard will be shown in red if the input signal has errors, but only if the analyser is connected to the input. If the
analyser is set to monitor the output, the input standard will be shown in brown.
The output standard will be shown in red if the unit is generating errors.

USING THE MENUS
The Menu keys select which instrument is in use as well as selecting the options for the unit. The bottom of the LCD display shows the
function of each Menu Key.
When in a specific function e.g. GENERATOR, ANALYSER etc, the cursor controls on the right hand of the unit select a field to edit. The
current field has a red box around it. Pressing the OK button starts or ends editing of that field. Check boxes are always in edit mode
and pressing the OK button inverts the current state. When editing some types of fields, the menu buttons at the bottom take on
different functionality to allow cancelling edit mode or setting the value for the field. When lists of options are displayed the menu
buttons allow selection of the first/last item in the list as well as paging through the available options. If the list of items is small, the
available items may be displayed on the menu buttons for instant access. The buttons along the bottom of the LCD display change the
currently displayed page when not editing a data field. The left hand button always selects the top level menu and system overview
page.
SCREEN-DUMP
The current LCD screen may be saved to the internal memory by pressing and holding the OK button. The SX will ‘beep’ when this
happens and a dialog will be displays which shows the file name that was saved. Files are always saved in the screendumps directory on
the SX and may be downloaded via FTP or using the downloads link on the web browser.
MAIN MENU
This page displays an overview for the system. It shows the video input and output standards and frame rate. The audio status for the
generator shows which audio groups are being generated whilst the audio status for the input shows which groups are present and an
overview of the channel status for each audio channel. Audio channel status is displayed as ‘P’ if PCM audio is present, ‘N’ if NON-PCM
audio is present, ‘E’ if Dolby-E packets are present or V if the validity bit is set. Dolby-E program configuration and Timing status is also
displayed if the Dolby-E analysis option has been purchased and a Dolby-E signal has been detected on the selected input. If the
generator is generating errors then the video standard is displayed in red. If the input detects errors, then the input standard will be
displayed in red if the analyser is monitoring the input. If the unit is connected to the network, the current TCP/IP address of the unit is
displayed in the Remote Control box. If the unit is NOT connected to a network and is set to DHCP mode, it will show ‘acquiring’ to
show that the connection hasn’t been made yet. The Sx model type is displayed at the bottom right corner of the screen.
The menu buttons select the page to display as follows:

SIGNAL GENERATOR
VIDEO SETTINGS
The unit supports all SD and HD SDI output standards including the 3GHz standards at 1080p/50/59/60. It will support Y,Cr,Cb formats
as well as RGB formats.
Output On:
Turns ON the output circuitry. Turn this OFF to save battery power if you are not using the video output.
Standard:
Sets the video output format. NOTE: This has had a major change in version 0.10.xxxx. Four drop-down boxes are used
to select video standard. The top-left box selects the basic mode of the unit and determines whether it is generating
normal SD/HD vide or 3G level A or level B video. Dual streams refer to the ability of the unit to generate two separate
pictures when transmitting 3G-level B in some formats. Which mode is selected determines which formats are
available.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 15
Only valid frame rates for the output standard may be selected.
Colour Format: Currently only YCbCr 4:2:2 10 bit picture formats are supported by the standard product but an Option may be
purchased to enable other colour formats. The following colour modes may be selected dependent on line standard
selected:
Pattern:
YCbCr 422 10bit
YCbCr 444 12bit
YCbCr 444 10bit
RGB 444 10bit
RGBA 4444 10bit
RGB 444 12bit
YCbCrA 4444 10bit
YCbCr 422 12bit
This selects the video pattern that is output by the generator. Many standard patterns are provided by the unit. You
may also download your own test patterns to the unit into the ‘Patterns’ directory and then select them using the
‘User File’ option in this field. See the ‘Unit File Structure - Patterns’ section for file formats supported. If a ‘User File’
has been selected, the ‘i’ button beside the file can be selected to get information on the file properties. Unsupported
file types will be displayed as a black image. If the video standard is changed while a user file is loaded and there is no
file for the new standard present, a black image will be loaded and the User File blanked.
NOTE: If Check field/Pathological is selected when a dual stream format has been selected, BOTH outputs will be
forced to check field due to internal hardware limitations. If another pattern is selected, the Check field pattern will be
de-selected. The exceptions to this are when Colour Field or Zone Plate are selected as test patterns.
The Check field/Pathological/PLL Check/EQ Check patterns will only look like the picture above when a YCbCr 422 10
bit colour mode is selected. Other colour modes will have different pictures but still create the SDI data stream
required by SMPTE.

When setting the colour using the YCbCr sliders, the RGB values will show the values for the current colour space.
Zone Plate
A basic zone plate generator is supplied with all units. The zone plate selector will only contain a single zone plate
entry. If the Zone Plate options has been purchased, then the zone plate selector will contain 3 user customisable
zone plates as well as several pre-determined zone plates. The ‘->’ button displays a dialog which allow the
parameters of the zone plate to be adjusted for the custom zone plates. Any of the preset zone plates may be copied
to the custom zone plates to act as a starting point for a new zone plate. As the zone plate settings are stored in user
memories a large number of custom zone plates are available for use. (See Zone plate dialog below for more details)
Preset Zone Plates provided with zone plate option:
Moving Zone-2H
A moving zone plate centred on the screen.
Static Zone-2H
A static zone plate centred on the screen from DC to the nyquist frequency at
left/right edges.
PHABRIX Sx Manual
Rev. 0.10.0043

Static Zone-2V
A static zone plate centred on the screen from DC to the nyquist frequency at
top/bottom edges.
Sweep-Horiz
A horizontal sweep from DC to nyquist frequency horizontally
Sweep-Vert
A vertical sweep from DC vertically
Grating-50kHz
A 50kHz frequency sine wave when using an HD output
Grating-1MHz@HD
A 1MHz frequency sine wave when using an HD output
Grating-5MHz@HD
A 5MHz frequency sine wave when using an HD output
Zone Plate Dialog
This allows editing of Custom zone plate
settings. Three custom zone plates may be set up by
the user and may be copied from one of the standard
zone plate presets using the ‘Copy To’ button.
Mode
This sets which type of Zone Plate is being produced.
It may be Zone Plate (circular pattern) Grating (Linear
horizontal or vertical grid) Sweep (Frequency sweeps
from start to end Frequency)
Start Phase
This sets the start phase of the sinewave generated
by the zone plate generator and is set in degrees
from 0-360
Phase Rate
This is used to set the rate of change of phase of the sinewave and thus changes the speed that the zone
plate moves at. It is specified in degrees per frame.
Angle
This changes the angle of the zone plate and thus can change a horizontal sweep into a vertical sweep or
rotate an elliptical zone plate pattern.
XScale/Start Freq. This sets the horizontal scale of grating patterns or the start value of the zone plate sweep frequency.
YScale/End Freq. This sets the vertical scale of grating patterns or the end value of the zone plate sweep frequency.
EDH:
If the output signal is SD (PAL-625 or NTSC-525) the insertion of EDH information may be turned on or off.
Errors:
This field enables the insertion of CRC or EDH errors into the video signal. This allows checking of third party error
detection circuitry. In SD there is one EDH ancillary packet per field. When errors are being inserted every EDH value
gets deliberately corrupted. This creates one error count per field. (Actually one AP error and one FF error). In HD
there is a CRC value calculated for each line. When errors are being inserted the CRC value on line number 1 gets
deliberately corrupted. This creates one CRC error count per frame.

Rev. 0.10.0043
Page 19
SMPTE 352
This checkbox allows the SMPTE 352 Payload ID field to be inserted into the video output stream. The state of this
checkbox is stored separately for SD, HD and HD-3G line standards. Note that for HD-3G line standards the Payload ID
should be turned ON.
Ident:
An picture or text ‘Ident’ may be set to identify an SDI source. This Ident can be turned on/off from this page but
changing the text/font/bitmap is performed by selecting the Edit button to bring up the Ident Dialog. An overview of
what the Ident is can be seen beside the Edit button. Note: If zone plate or colour field are selected, text cannot be
overlaid over them.
A smaller version of the video output signal is displayed on this page with any overlaid ident.
Ident Dialog
This dialog allows selection of either a user defined bitmap
picture which has been downloaded into the ‘Idents’ directory of
the unit or user defined text. For both types, the position of the
ident can be set to one of Top-Left, Top-Centre, Top-Right, LeftCentre, Centre-Screen, Right Centre, Bottom-Left, BottomCentre, Bottom-Right. When text ident is used, the font, font size
and colour can be specified. Several fonts are built in to the unit,
other true-type (.ttf) fonts may be downloaded as required.
GENLOCK SETTINGS
Source:
The generator may be locked to an input reference which may be either the reference input which is a Bi-Level/TriLevel sync or may be locked to the video input. Alternatively, the generator may free run.
Delay:
If the Genlock source is not set to free-run, the video output is frame locked to the reference. The delay of the video
output may be adjusted by lines and samples with the delay also shown in micro-seconds.

AUDIO SETTINGS
The unit can embed an audio signal on all 16 embedded audio outputs. If the SxA version has been purchased, the AES output source
may also be set up.
Group n:
Each of the four groups may be separately enabled. When enabled, the source and level of each channel in a pair can
be selected.
Source:
The source for each channel may be Silence, Fixed tone (a range of fixed frequencies), variable tone (where the
frequency can be set on 1Hz steps from 1Hz to 23.99kHz), white noise. The AES input may also be selected if present.

This links the left and right channels of a pair so that changing the level on the left hand channel changes the level on
the right hand channel.
MASTER
The master level sets the 0dB level for all the embedded audio channels. Thus if the Master level is set to -18dB and group 1 pair 1
output is set to -2dB, the actual level output on that pair is -20dB. This feature allows all embedded outputs to be adjusted together as
well as giving a simple method to change from -18dB to -20dB based standard levels. The Master level will not adjust the level of an AES
input signal selected for embedding on SDI output.
AES O/P
This is only available on the SxA and SxE models. The AES o/p control selects the source for the AES output of the unit. The source can
be:
•
The AES input (via the built-in sample rate converter) to allow easy conversion to 48kHz sample rate AES signals.
•
A mirrored output of the specified embedded AES stream contained within the SDI output to allow easy generation of audio
tones or white noise.
•
One of the embedded input pairs on the SDI input to allow use as a de-embedder.
PHABRIX Sx Manual
Rev. 0.10.0043

•
Off, if the output is not required.
Note that the AES output is always at a 48kHz sample rate. The AES input may be at any sample rate from 32kHz to 192kHz.
ANALYSER
The signal analyser displays the video input or output signal . On any page, if the page button is pressed again the video signal will be
displayed in full screen mode. While in full screen mode, if the video input signal is not present, a message saying ‘No Video’ will be
shown. The source for the analyser is set by the field at the bottom right of the page. The current line and sample are the same for all
pages of the analyser and therefore when selecting a sample on the Signal Data page, the cursor will show where that is on the ‘Full
Picture’ page.
PICTURE
On this page, the video picture is displayed in a window as a down-converted display. The picture will automatically view the horizontal
or vertical blanking areas if the line or sample values are in the blanking area. If the focus cursor is moved to the picture window and OK
pressed, the cursor may be used to scroll around the window. Press OK again to cancel this mode. When in zoom mode, the cursor is
always in the centre of the window and the picture scrolls behind it. If the cursor is moved to an area of interest on the picture, the
same area will be visible on the SDI data option (if purchased).
If the picture window is focussed and current tab button is pressed again to enter full-screen mode, the cursors may be
moved by pressing the OK button again. NOTE: The normal cursor menu keys may be used but are not visible. Press OK again
to cancel cursor adjustment mode.
Line:
Specify the current line for analysis.
Sample:
Specify the current sample for analysis.
Field:
(Only for interlaced formats) This control selects the field for analysis. If the current line is in Field 1, changing the field
will change to the same line in field 2. The field number will change to show the correct field for the current line
number.
Blue:
Show only the Blue aspect of the picture Blue.
Aspect Ratio:
The aspect ratio of PAL (625 lines) may be set to be either Auto, 4:3 or 16:9 as required for the source signal. NTSC
(525) signals are always 4:3 aspect ratio and HD signals are always 16:9.

Rev. 0.10.0043
Page 22
Zoom:
If not checked, the picture displayed is a down-converted picture to fill the window or the full screen as requested. If
checked, then a pixel on the units LCD display will reflect a pixel in the video signal. In zoom mode, no filtering is used.
ActPix: If checked, only active picture is displayed for picture view and waveform monitor, all other VBI data such as TRS words ANC
data and audio is blanked.
Cursor: A cursor may be turned ON over the area of the picture specified by the specified line and sample.
Source: The analyser can view either the video SDI input or the Generator output so that comparisons can be made between input and
output.
AUDIO METERS
This page shows up to 16 audio channels. The source for each block of 8 meters may be independently set to allow simultaneous
metering of 8 inputs and 8 outputs or all 16 channels in an embedded SDI stream. If AES inputs or outputs are present (SxA) then these
may also be metered. At the bottom of each meter is the current audio level for that channel in dBFs (decibels relative to 0dB fullscale).
The scale used by the meters may be set to -18dB or -20dB according to the standard operating level used.

DOLBY-E METERING (DOLBY-E ANALYSIS OPTION)
If the Dolby option has been purchased, the meters may be set to display the encoded Dolby levels for the specified audio pair or AES
input.
NOTE that Dolby audio cannot be heard on the speaker as a Dolby decoder is not present.
SIGNAL DATA (SDI DATA OPTION)
This page shows the video signal as a data stream in several formats as described below. In each mode, the data may be displayed in
hexadecimal, decimal or binary formats. The binary format is not available in grid mode. The data may also be displayed as 10bit or 8bit
format.
To simplify scrolling around the SDI signal view, use the cursor keys to move the red focus rectangle to the data display and press OK.
The focus rectangle should change to a blue colour and the cursor keys allow the display to be scrolled in any direction. The menu keys
at the bottom allow the Line/Sample to be adjusted by 10 or 100 in any direction.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 24
Note: The line number of a line of video changes at the end of active video. This gives the strange side effect that the line
number for pixels in horizontal blanking is the same as the line number for the active picture after that line.
Grid:
In this mode the data is shown in an X-Y format with lines and samples at the same time. Thus this is a representation of the
picture but in data format. If the cursor keys are used to select the grid window and ‘OK’ pressed, the cursor keys will scroll
around the window. The luma (Y) channel is shown in white whilst the Cr and Cb channels are shown in with a red or blue tint
respectively.
Strm:
This is one of 3 modes for displaying the samples on the current line only. The cursor keys may be used to scroll the sample
number when ‘OK’ has been pressed. The ‘info’ column shows the type of data being displayed.
AP
VBL
HBL
Active picture
Vertical blanking
Horizontal blanking
Comp: This is a similar to the Strm mode above but in a component mode with Cr and Cb in different columns. See Strm mode above
for the info column description.
Split:
This mode shows the 2 streams split into 4 parts to show Y, Y’, Cr and Cb in separate columns. See Strm mode above for the
info column description.
Source: The analyser can view either the video SDI input or the Generator output so that comparisons can be made between input and
output.
Note: When in Colour modes other than YCbCr 422 10 bit, the pixel RGB or YCbCr values are packed into 10 bit values across
the different streams and thus will give unfamiliar values. When the ‘UnPack’ check box is checked the values in the active
picture are unpacked to RGB or YCbCr values.
WAVEFORM MONITOR
The waveform monitor displays the analyser input in an oscilloscope like form.
The display may be restricted to a single line or all lines may be displayed at the same time. The display can be formatted as all streams
(Luma and Chroma) or just a single stream. The streams may be in YCbCr or GBR formats.
The display may also be magnified to examine a specific part of the waveform.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 25
WAVEFORM CONTROLS
The line, sample and field controls all track the related controls on other pages.
The ‘All’ checkbox forces the waveform monitor to display all lines, overlaid on each other. Otherwise the specified line is displayed.
The waveform display format is set using the ‘Setup’ button. The waveform monitor displays the selected signal in one of 5 formats as
set by the Mode control:
YCbCr
Y
Cb
Cr
GBR
Red
Green
Blue
The Y, Cr and Cb waveforms are shown as three separate waveforms in a Parade format
Only the luminance channel is shown
Only the blue chroma channel is shown
Only the red chroma channel is shown
The Green, Blue and Red waveforms are shown as three separate waveforms in a Parade format
Only the red channel is shown
Only the blue chroma channel is shown
Only the red chroma channel is shown
The next 2 controls show the vertical and horizontal magnifications. If either value is set to a value other than x1, a vertical or horizontal
offset will be shown on the bottom right edge of the waveform display. The offsets are set by moving the focus cursor to the waveform
window and pressing OK. The menu keys can then be used to scroll around the window. The offset will be the same for all
magnifications values so switching between x1 and x5 will not lose the offset used in x5 mode.
The vertical offset values are in signal level bits but displayed in the current scale units so switching between scales will keep the same
offsets.
Cursor Mode:
Cursors may be displayed over the waveform to allow measurement of time or amplitude values. The cursor may be
set to several modes:
Off:
Cursors are hidden
Pict:
The cursor is displayed at the current pixel point. If in YCbCr or RGB mode, three cursors are displayed. Otherwise a single
cursor is displayed. The cursor position tracks across the picture monitor and Signal Data tabs.
Ampl:
Two cursors are displayed to allow measurement of signal amplitudes.
Time:
Two cursors are displayed to allow measurement of signal timing.
Both:
Amplitude and time cursors are displayed.
To use the cursors, use the navigation keys to move the focus to the waveform display and press OK. You should then get a display
similar to that below. Note that the menu keys shown depend on the display mode and cursor mode.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 26
The navigation keys now move the selected cursor around the waveform display which will scroll if moved out of the visible area. The
x10 and x100 buttons magnify the action of the navigation keys if held down.
The Select Window button is only available in YCbCr or RGB modes and selects the window that the cursor is displayed in.
The Amplitude Cursor and/or the Timing Cursor buttons switch the currently active cursor. In each direction two cursors are displayed.
The currently active cursor is the one displayed as a full line (rather than the dotted cursor). The bottom of the waveform screen shows
the cursor measurements in the current format which may be Decimal, Percentage or Hexadecimal for amplitude measurements or
Pixels/uS for timing measurements. The difference between the two cursors is also displayed in absolute form.
The Cursor Mode button changes the current mode without having to leave the navigation window.
Source: The analyser can view either the video SDI input or the Generator output so that comparisons can be made between input and
output.
SETUP BUTTON/DIALOG
Active Picture: If checked, only active picture is displayed for picture view and waveform
monitor, all other VBI data such as TRS words ANC data and audio is blanked. This control
tracks the state of the ActPix control on the Picture tab.
Vertical Scale: The axes and measurements for the waveform monitor can be displayed
either in percentages or in hex or decimal values as required.
Horizontal Scale: The timing measurements may be set in either pixels or micro-seconds (us)
VECTOR SCOPE
The vector scope may be set to show either the 100% bar positions or 75% positions. The colour bar position boxes will change
according to the colour space for the current input video standard.
The ‘All’ checkbox forces the waveform monitor to display all lines, overlaid on each other. Otherwise the specified line is displayed.

SIGNAL INFORMATION
These pages give a detailed view of the status of the input (or generator output) signal. They are sub-divided into Video, Misc, Audio
and Ancillary (ANC) status.
VIDEO STATUS
EDH/CRC ERRORS
This displays the EDH or CRC status of the analyser input as appropriate for the video standard being monitored. The status of each
EDH/ CRC count is displayed as the number of seconds since an error occurred. The individual CRC fields may be reset individually or
together. The ‘running time’ field shows the time since the last error reset occurred. The error rate field shows the number of errors per
second.
When analysing a 3G-Level B signal, the CRC status is displayed for each link or stream present according to the input video
format. On an SxD with 2 video inputs, only one 3G-Level B may be analysed for CRC status at a time.
NOTE: In the current version of software, errors in ancillary packets are NOT checked. This will be added in a future version.
EDH DATA
If the signal is SD (PAL-625 or NTSC-525) the EDH values for both active picture (AP) and full-field (FF) are displayed for each field. To
enable engineers checking EDH integrity, the EDH values calculated for active picture and full-field are also displayed.
Under normal conditions, the EDH-AP values should be constant, the full-field values may change if audio or other ancillary data is
embedded in the SDI signal.
The EDH flags for active picture, full-field and ancillary data are also displayed for diagnostic purposes.
Edh: Error Detected Here:
This is set to 1 if a SDI error was detected. In the case of ancillary data, this means that one or more ANC data packets had an incorrect
checksum.
Eda: Error Detected Already:
This is set to 1 if a SDI error was detected in the signal received by the previous device.
Idh: Internal error Detected Here:
PHABRIX Sx Manual
Rev. 0.10.0043
Page 28
This is set to 1 if a hardware error was detected in the previous device.
Ida: Internal error Detected Already: This is set to 1 if an idh flag was received by the previous device.
Ues: unknown error status: This is set to 1 if the previous device received an SDI signal from a device not supporting EDH.
CABLE LENGTH
The Sx measures the cable length connected to the SDI input BNC and the measurement is only an approximate value.
The cable type maybe set to one of the following:
Belden 8282, 1694A, 1505, 1855A.
Canare L-5CFB
Image 1000
The selected cable type will affect the cable measurement.
ACTIVE PICTURE CRC
16-bit CCITT CRCs are calculated for the active picture data of the received signal. This can be used to give a known value for known
static picture content and allows the user to determine if the active picture content is as expected.
CRCs are calculated independently upon each 10-bit stream (luminance and chrominance) of the interface.
For example the Sx generated 1920x1080, 100% bars in YCC422-10 should always produce a luminance CRC of 0x0AB4 and a
chrominance CRC of 0xB88E, no matter what scanning mode (interlaced, segmented frame or progressive) or frame rate is used.
Note: when using 4:4:4, 4:4:4:4 or 12-bit video formats (in dual-link or 3Gbps) the CRCs are calculated for each of the packed 10-bit
virtual interfaces and will therefore generate different values from those for YCC422-10.
See the “Active Picture Crc Technical Information” section at the end of the manual for details of CRC calculation.

VIDEO FORMAT
This displays the currently detected line length for both active video and full line including blanking as well as the number of active lines
for the inputs present. NOTE: The video frequency displayed is only correct if the unit has been calibrated and free running or has been
connected to an accurate reference input.
If the input signal is not a known signal (i.e. the line count or pixel count is not recognised) The input status on the top line will show
“Invalid” but the values in this section will be updated every few seconds.
PAYLOAD ID – SMPTE 352
If the unit has detected a SMPTE 352 ancillary packet, it will be displayed here in hex and decoded format.
The display shows the transport media, frame rate and interlaced/progressive/segmented frame mode, as well as colour format, bit
depth, dynamic range and channel number. See the SMPTE 352 specification for further details.
When analysing a 3G-Level B signal, the SMPTE 352 status is displayed for each link or stream present according to the input
video format. On an SxD with 2 video inputs, only one 3G-Level B may be analysed for 352 status at a time.
AUDIO STATUS
The Channel Status for the selected audio channel is displayed in decoded form as well as a hexadecimal dump of the bytes. The source
may either come from the input signal or from the generator for comparison purposes.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 30
ANC INSPECTOR (SDI DATA OPTION)
The data contained in Ancillary packets may be displayed and decoded.
The data ID for the packet to be displayed should be selected using the DID field. A description of the DID is shown next to it and the
header of the packet and checksum is displayed immediately below. The data packet is displayed as a hexadecimal list at the bottom of
the page and may also be decoded into a text format.
If an error occurs in the packet, the header and checksum are displayed in red.
The display of data may be frozen by pressing the Freeze checkbox.
If the On Error checkbox is checked an error in the data packet will cause the display to be frozen and the Freeze checkbox will turn red.
Un-checking the freeze button will restore normal operation.
DOLBY-E STATUS (DOLBY-E ANALYSER OPTION)
The Dolby-E status option allows display of the Dolby-E meta data present in the selected audio stream and determines whether the
Dolby-E packet is timed correctly on the SDI video stream. This option therefore allows the Dolby-E aspect of the signal to be timed
correctly at all stages in a broadcast chain.
NOTE: In order for the Dolby-E data to be decoded correctly, the internal audio circuitry requires a reference
that is synchronized to the input signal. The Generator Reference MUST therefore NOT be set to Free-Run or
Dolby-E errors may be detected. The description field will display “Invalid Reference” if an incorrect reference is
selected.

Page 31
In the example above, the SDI signal contains embedded audio with Dolby-E present on one or more audio
pairs. The Sx needs to lock its internal audio clock to the SDI signal (Generator – Genlock – Source=Input 1)
and the Dolby Timing source should be set to SDI.
AES IN
Sx
Dolby-E AES Source
REF IN

Dolby-E using AES source (such as
Dolby DM100)
In the example above, the AES signal contains a Dolby-E stream. The Sx needs to lock its internal audio clock
to the external reference signal (Generator – Genlock – Source=1Ref) and the Dolby Timing source should be
set to Ext.Ref. The AES source MUST be locked to the same reference as the Sx.
Source selection:
The Dolby-E may be monitored from any of the SDI input embedded audio channel pairs or the AES input.
Dolby Framing Values:
It is important for the Dolby-E packet to be positioned well away from the video switching line so that Dolby-E
packets are not corrupted by downstream switchers. At all places in the signal chain where audio can be
delayed by a different value to the video, the Dolby-E packet needs to be re-timed to make sure that this
timing specification is met. The position of the Dolby-E packet in the video frame is displayed in lines and
micro-seconds (us).
Timing source:
Dolby-E timing may be measured relative to the SDI input or the External reference. If the ‘Ideal’ checkbox is
checked, the Dolby-E Frame timing is relative to the normal position that it should be, i.e. it should be as close
to 0 as possible. Each video standard has a specified ‘Ideal’ line number that the Dolby-E packet should start
on. If the Dolby-E timing line is outside the valid range of lines it will be displayed in red. If it is outside the
ideal range it will be displayed in dark green – this is still a valid Dolby-E position but not recommended by
Dolby.
If you do not have the same reference as the SDI source, you will have to set the Reference Source and Dolby
Timing Source to be the SDI input.
IMPORTANT: If Dolby-E is present on a fast frame rate signal (50p, 59p or 60p) then it should always be
referenced to a interlaced reference at the same field rate as the packet length is longer than a single frame
and must start at the beginning of an even numbered frame.

be able to listen to the Dolby-E signal.
Note that the LFE channel audio levels do not seem to be metered by current Dolby encoding modules.
See the logging section for details on which changes of Dolby-E status may be logged.
VIDEO TIMING
The timing of SDI input signals is displayed relative to the external reference. If no reference is present then an error message is
displayed. If the signal is timed to within +/- 2 samples the values are displayed in black in lines and samples (spl) If mis-timed, then they
will be displayed in red. A bar graph also displays the timing value which may either be line timing (+/- 0.1 lines or +/- 0.5 lines) or frame
timing (+/- 0.5 frame). The total timing value is also displayed in micro seconds.
The RED arrow on the bar shows the SDI input timing and the BLUE arrow shows the current target timing point. The BROWN line
shows the timing of the reference signal.
To compare timings of different signals, connect the signal to be compared to the SDI input and select the “Offset” button to make this
the current offset. All future timings will be relative to this offset value.
To clear the current offset, move the focus to the 2 offset fields, press OK to edit them and then press default.
SXD ADDITIONAL FEATURES
PHABRIX Sx Manual
Rev. 0.10.0043
Page 34
As the SxD has two inputs, the timing of each input may be displayed relative to the reference.
The timing difference between the two inputs may also be measured, even without a reference input. This allows Dual-Link signals to
be measured for timing errors due to different cable lengths/types.

memory.
Move the cursor to the ‘Clear’ button and press ‘OK’. The memory list will show the default name for that memory. A cleared memory
cannot be recalled.
EXPORT
Memories can be exported to a single file for backup purposes and re-imported into the internal format. This allows different sets of
memories to be used for different tasks, such as command scripts. Exported memories are in a text format and so may be edited on a
PC and downloaded to/from the backups directory on the unit via FTP or USB.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 36
To export memories, select the Backup... button which will open a window to select the file to create. Existing files are shown and a
new filename may be selected using the File Name edit box. Select the Save button to create the backup file. The filename created will
have a .mem file extension.
To import memories, select the Restore... button which will open a window to select the file to import. Existing files are shown and one
should be selected before the Load button is pressed. Select the Load button to import the backup file.
NOTE: When importing a backup file, all existing memories are deleted before the backup file is loaded so make sure that they are
backed up first.
DISK SPACE
The disk space section shows total size of the internal flash disk and how much is used as a percentage and how much is free.
COMMAND SCRIPTS (COST OPTION)
Command scripts allow sequences of actions to be stored and recalled thus allowing often repeated test procedures to be run. Each
step of a sequence has an associated action and time that the action is valid for. Command scripts are stored in the ‘Scripts’ directory
on the unit and may be downloaded to the unit via the USB port or via FTP transfers to the unit. See the section on Remote File access
for further details. See also the section on file formats for details of command script formats.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 37
A script requires a set of memories to set the unit up and then a script file which recalls those memories and specifies times and actions
for each step. It is worth while keeping all the memories in an ‘archive’ file created using the Memory Backup feature above. This
archive will then be recalled when selecting the script and all memories will be guaranteed to be present. When recalling memories, it is
worth using the checkboxes so that only the relevant settings are saved in the memory.
A sample script, “SystemTest” is included in the software distribution. (Note that if an action refers to a screen not available on the
hardware platform (e.g. EYE pattern on an SxA or SxD) that action will not be run.
MAKING A SCRIPT REPORT
If the ‘Make Report’ check box is checked, a web page will be created once the script has completed. The results of all actions will be
shown in this report, including any screen dumps performed. This report can be viewed via the Downloads link on the web browser and
thus printed for future reference. Each time a script is run, a new report is created with a unique name. Thus the same script may be
run on multiple SDI sources and different reports created for each source.
CUSTOMISING REPORTS
By default, script reports display the Phabrix Logo at the top left hand corner. To replace this with your own companies logo or another
image, replace the file “logo.jpg” in the /mnt/mmc/reports directory using FTP (see section at the end of the manual on how to use FTP)
The file “report_template.html” in the reports directory is used to create the web report. When creating a report the software looks for
the following template filenames in this order:
SCRIPTNAME.tpl.html
- where SCRIPTNAME is name of script file
SCRIPTNAME.tpl.htm
- where SCRIPTNAME is name of script file
reports.tpl.html
report_template.html
This allows reports to all look the same or for certain reports to be further customised.
These template files are standard HTML web pages but with the ability to replace certain “tokens” with text created by the script.
See the standard file: report_template.html for examples of the tokens.
Tokens available (they are case insensitive)
<#REPORTNAME> insert the name of the report at this point in the report. Reportname includes the unique report number.
<#DATE>
<#USER>
Insert the currently selected user (if any)
<#REPORT>
Inserts the results of the report
Token Parameters
All tokens may be extended by adding optional parameters e.g.
<#USER before=”<b>” after=”</b>”>
PHABRIX Sx Manual
Rev. 0.10.0043
Page 38
This will insert the html string <b> before the user name and </B> after the user name if user name is set.
Date Parameters
The <#DATE> token may also have a format string to define how the date will be displayed.
The format string may contain:
%a abbreviated weekday name

Move the cursor to the ‘New’ button and press ‘OK’. A new script will be created called ‘NewScriptn’ where ‘n’ is the next available
script number. See also ‘Renaming a command script’.
ADDING STEPS TO A COMMAND SCRIPT
Move the cursor to the ‘Add Step’ button and press ‘OK’. A new step will be created with the default action of Recalling Memory 1 in 1
second. Multiple steps can be created at this stage and then the actions edited later.

EDITING STEPS IN A COMMAND SCRIPT
Select the step to be edited by moving the cursor to the step list and pressing ‘OK’ and then using the cursor keys to select the step.
Press ’OK’ again to select this step and update the action and time fields for the step. Move the cursor to the field to be edited and edit
as required.
SCRIPT ACTIONS
Step Action is one of:
RECALL MEMORY,
Loads the memory specified in the Memory field. When recalling a memory you need to be aware that changing certain fields can take
a few seconds before data stabilises. For instance when changing the generator output standard in a memory can take about 3 seconds
before the input change is detected. This time will depend on the delay between output and input. During this time the input may come
and go and errors may be detected on the line. Thus if you are logging errors you will get spurious errors during this ‘switchover’ time. A
step with a PAUSE action should be inserted if this is the case.
CHECK INPUT ERRORS,
Check for any input errors for the selected input during the Time specified. If there are any errors an event is added to the event log .
CHECK EDH/CRC CHANGES
This will check if the active picture CRC value for the selected input changes and add an event to the log if one occurs during the
specified time period. If a CRC value is included, this will be checked against the value detected and an error given if it doesn’t match.
Note that the CRC value is actually a 32 bit value as shown on the Sig.Info-Video status page which can optionally have a space between
the 2 16bit fields. Thus if the CRC value is DA54 B111 then the value in the script CRC field may be “DA54B111” or “DA54 B111”. If no
value is included then only changes will be detected. This is useful for detecting errors in upstream equipment when used with fixed
test patterns.
PROMPT USER
This will put a short prompt on screen in a dialog asking the operator a question and waiting for OK to be pressed to continue.
CLEAR EVENT LOG
This will clear the event log which is useful when starting a test script so that the event log starts in a known state. If the script is
looping, the event log will only be cleared on the first loop.
DISABLE LOGGING
This disables logging globally while a major change in output/input status is about to take place so that unwanted log events are not
added to the log.
ENABLE LOGGING
This re-enables event logging after disabling it above.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 40
CLEAR ERROR COUNTS
This clears all EDH/CRC error counts and should be run before checking for errors.
PAUSE
This waits for the specified time before running the next step in the script. (Normally used after a memory is recalled that can take time
to complete or if external equipment needs settling time).
SAVE STATUS
This saves the current status of the unit as an XML file and also added to the report in text form. The file will be saved with the name
specified in a directory with the same name as the Script file in the Scripts directory. Thus if the Script is called “TestSystem” and the file
is set to “3GStatus” an xml file called /mnt/mmc/Scripts/TestSystem/3GStatus.xml will be created. Once the script has been run, all
such created files may be downloaded using FTP to create a results file. The format of the XML file is determined by the file
“/mnt/mmc/scriptxmlformat.ini” which determines which control IDs are used to create the XML file. Note that if you edit this file, you
should take a backup of it as it will be overwritten when a software update takes place.
SELECT TAB
The specified tab on the Sx will be displayed. This allows the user to check a screen, waveform display or event log etc. This action will
normally be followed by a pause or prompt action.
SCREEN DUMP
The specified Tab will be displayed and saved to the current report directory as well as being added to the report file if active. The
filename must be specified as a unique filename for this Script.
SELECT USER
This action will display a dialog with a list of users to choose between. The selected user may be displayed at the top of the report if
required. User names are separated with commas (,)
CHECK AES I/P
Check for AES input errors in the step Time. If there are any errors an event is added to the event log.
CHECK EYE
Checks that the eye amplitude and rise/fall times are within the SMPTE specifications for the time period specified.
CHECK JITTER
Checks that the jitter levels are under those set in the logging jitter threshold fields for the time period specified. See logging setup
section for further details.
CHECK METER LEVELS
PHABRIX Sx Manual
Rev. 0.10.0043
Page 41
This action checks that the level for any visible meters is at the level set by the meter scale. This level may be -18dB or -20dB. If the level
is over 1dB greater or less than that value an error will be inserted in the log and report files. If any groups are missing, these will be
ignored by the test.
DELETING STEPS IN A COMMAND SCRIPT
Select the step to be deleted by moving the cursor to the step list and pressing ‘OK’ and then using the cursor keys to select the step.
Press ’OK’ again to select this step. Move the cursor to the ‘Delete Step’ button and press ‘OK’.
DELETING A COMMAND SCRIPT:
Move the cursor to the list of command scripts on the left hand side and select the script to be deleted as the current script. Then move
the cursor to the ‘Delete’ button and press ‘OK’. The currently selected script is the one that is deleted.
RENAMING A COMMAND SCRIPT:
Move the cursor to the list of command scripts on the left hand side and select the script to be renamed as the current script. Move the
cursor to the name edit field and press ‘OK’. The menu keys at the bottom of the screen will change to show text keys similar to a
mobile phone. Pressing a key repeatedly will cycle through the characters for that key. Pressing a different key will move the cursor to
the next position and insert the first key value for that key. The cursor left and right keys can be used to move the position of the text
cursor which is where the next character will be inserted. The ‘Back Space’ key will delete the key to the left of the cursor. The ‘Cancel’
key will cancel edit mode and restore the original text. Once you have finished editing the name, press ‘OK’ to rename the script.
RUNNING A COMMAND SCRIPT:
Move the cursor to the list of command scripts on the left hand side and select the script to be run as the current script. Move the
cursor to the ‘Run’ button and press ‘OK’. The Run button will now become a ‘Stop’ button to stop the running script.
While the script is running the total number of errors detected is displayed on the scripting page as well as on the count-down timer
dialog. Once the script has completed, the total number of errors is added to the end of the event log as well as to the report if created.
LOOPING A COMMAND SCRIPT:
By default a script will run all steps and then stop running. The ‘Loop’ check box allows a script to loop until stopped. This feature allows
testing of a system forever for heat-soak testing in a manufacturing environment or to check for system reliability over a period of time.
The Loop Count field shows how many loops have been run and how many hours and minutes the script has been running for.
LOADING ARCHIVE FILE AS PART OF A SCRIPT
An archive file may be loaded when the command script is run by selecting one in the ‘Archive File to use’ field.
The archive file contains all the memories used by the script – this is optional as not all scripts use memories.
Note that if the memories are updated while debugging a script, the memories MUST be saved to the archive or the settings
will be lost. A dialog is shown confirming overwrite of memories when this happens.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 42
SCRIPT RESULTS
Once a script has completed (or a looping script has been aborted) a line will be added to the log (if enabled) and report file to show
how many errors were detected during the running of the script. The log need only be examined if errors have been detected.
EDITING COMMAND SCRIPTS ON A PC:
Download the required Script file from the Sx using FTP over the Ethernet port connection. The file is a plain text file and can be edited
using NotePad or a similar editor.
NETWORK SETUP
TCP/IP SETUP
PHABRIX Sx is fully networkable and has a complete network interface to allow control of any unit from any other unit. All units on a
network need an ‘address’ so that the other systems know how to talk to them. To setup network addresses select the “Setup” button
and edit the settings. If you have a DHCP server on your Ethernet network, check the DHCP box and a TCP/IP address will be assigned to
the unit automatically. If your network has ‘static’ (non changing) addresses, you will need to see your network administrator to get an
address assigned to your unit and to get the Subnet mask and default gateway address.
If your Sx was turned on without the network connected, you will have to select the “Re-connect” button to set networking
up correctly. This is because the Ethernet connection auto senses whether it has to swap the cable over which means that
you can use any Ethernet cable with the Sx but it also requires the Ethernet connection to be present when starting up the Sx.
REMOTE CONTROL OF UNIT (COST OPTION)
To allow remote control of a unit, you must have the TCP/IP address of the unit set and the Remote Control ‘On’ check box must be
checked.
The list box shows a list of current connections made to the unit. This includes the web browser connection (127.0.0.1) which may be
seen intermittently as the web browser connects every few seconds and then disconnects again. See the remote control
documentation available for download for more information on the protocol and method of control.

Page 43
REMOTE WEB BROWSER ACCESS
The PHABRIX Sx may be controlled via your web browser. Operation has been tested using Firefox, Opera, Safari, Chrome and Internet
Explorer but should work with any browser which allows JavaScript.
To connect to the PHABRIX Sx, find out its IP address and type it into the web browser.
You should see a screen like this:
Clicking on the buttons works exactly like the unit that you are connected to (note that auto-repeat doesn’t work due to browser speed
limitations). The LCD screen on the browser image is updated every 10 seconds but may be refreshed manually by clicking the LCD area
on the browser.
The “Log” link on the right hand side may be selected to fetch the current Event Log from the Sx.
The “Status” link on the right hand side may be selected to fetch the current unit status in XML format. It can be saved to a local PC for
further processing. The control IDs displayed in the XML file are determined by the file “/mnt/mmc/xmlformat.ini” which may be edited
by the user although note that it should be backed up as it will be over-written when software updates take place.
The “Downloads” link displays a further page allowing screen dumps and report files (Command script option) to be viewed.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 44
Screen dumps of the PHABRIX Sx can be made using the browser’s or operating systems facilities. (On Windows(tm) Alt+Print Screen
causes the web browser’s window data to be stored on the clipboard).
SETTING UP A WINDOWS™ PC FOR DIRECT CONNECTION
A PHABRIX Sx may be connected to a PC via your network or directly using an Ethernet cable between your PC
and the Sx. The PHABRIX Sx does not require a cross-over cable as it auto-senses the connection, thus any
Ethernet cable may be used. The PHABRIX Sx should be set to a fixed IP address.
The PC’s network settings should be set to give a fixed IP address in the same range as the PHABRIX Sx’s IP
address, but use a different address. To set up the PC, go to the Windows control panel and select Network
Connections and then select Local Area Connection and get its properties dialog.
Select Internet Protocol (TCP/IP) which is at the bottom of the list and click the ‘Properties’ button.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 45
A new dialog should appear. Set the IP address to a different value to that of your PHABRIX Sx but keep the first 3 numbers the same.
The Subnet mask should be the same as that on the PHABRIX Sx and should be as shown above.
The orange LED on the PHABRIX Sx Ethernet connector should light when connected and the green light should flash when network
data is detected.
The PHABRIX Sx should be set with DHCP OFF and the other settings as shown. The DNS server setting MUST be set to the address of
the PC that is directly connected for FTP and Web access to work.
The IP Address can be any value within the valid Subnet region.
MISC.
This page shows serial numbers, unit MAC address, version information and battery state. It also allows the date and time to be set and
factory default settings to be recalled. The options security code is entered on this page if options are purchased.
CHANGING THE DATE/TIME:
Check the ‘Enable Change’ checkbox under the date and time fields and then use the cursor to move around the date and time. Press
‘OK’ to edit a field and again to complete the change. When all fields have been edited, uncheck the ‘Enable Change’ check box and the
new date and time will be set.
Note that the date may not be changed while a 30 day trial option is active.
CHANGING THE DATE FORMAT:
The date format used on logging screens etc may be set using the Format selection control. Three formats are available: Date-MonthYear, Month-Date-Year and Year-Month-Date.
SETTING LCD BRIGHTNESS
Use the LCD brightness slider to set the LCD brightness, using a lower brightness will reduce the current drawn from the battery and
thus lengthen battery life.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 46
SETTING SCREEN SAVER MODE
When the unit is battery powered the screen saver will operate after a user defined time period and reduce the LCD brightness down to
its lowest level. This will lengthen battery life. Pressing any key will restore the previously set LCD brightness.
SETTING USER LANGUAGE
The language used to display the menus in may be changed to one of the supported languages. (Currently only English is supported)
CHANGING OPTIONS SECURITY CODE
When new options are purchased for the unit a new Security Code will be supplied. This is specific to this unit and cannot be used on
other units. The security code is entered using the Edit field below the System Option list and is edited by pressing OK and using the
menu function keys. If an incorrect Security code is entered a dialog will be displayed. The new Security code will only be saved if it is
valid, the old code will be used until a valid code is entered. Once a valid new code has been entered, the list of options provided by
that code will be displayed. The options code is stored independently to memories and system settings.
UTILS
This screen shows system voltages and temperature but only on the SxD and SxE and later versions of SxA.
Hardware error counts can also be viewed. Contact your local dealer if they are non-zero.

This page adds features for special use.
CLEAR MEMORIES
Check the ‘Enable’ checkbox above the ‘Clear ALL’ button. Press the ‘Clear ALL’ button and all the user memories will be deleted.
DEFAULT SETTINGS
Check the ‘Enable’ checkbox above the ‘Set Defaults’ button. Press the ‘Set Defaults’ button and the factory defaults will be recalled.
This will not affect the system Security Code or Free Run frequency.
GENERATOR FREE-RUN
Press this button to calibrate the free running frequency using the External reference or Video Input as selected by the Generator –
Genlock page. If no input is present or the Generator is free running, an error dialog will be shown. The calibration will take a few
seconds to take place and once completed, the calibration value will be shown. This calibration value is not lost when memories are
cleared or factory defaults recalled above.
SOFTWARE UPGRADE
The unit may download and install new versions of software when available. This process is a two stage process: Download the
software and then install it.
DOWNLOAD
Make sure that the network settings are correct and that the unit is connected to the internet via the Ethernet connection. Note that
the unit should be connected to the AC adaptor so that the battery state does not affect the download process.
Pressing the Download button will cause the current release of software to be downloaded from the PHABRIX Web Site. This will take a
short time dependent on the connection to the Internet. Once the download has completed, the software will be checked for errors
PHABRIX Sx Manual
Rev. 0.10.0043
Page 48
before being stored on the unit for future installation. If the latest software is already present on the Sx, no software will be
downloaded and a message will be shown.
Multiple releases of software may be stored on the system so a unit may go back to a previous release if a test script requires it.
INSTALL
Note that the unit should be connected to the AC adaptor so that the battery state does not affect the installation process. The unit
does NOT have to be connected to the Internet during installation.
Select the release of software to install using the field with releases listed. The largest number is the latest release. Select the ‘Install’
button and a confirmation dialog will be shown. Press “Yes” and the installation will start. This process takes several minutes to
decompress the software, extract the files and then reprogram the hardware and during this time the unit MUST be connected to the
AC adaptor or corruption of the unit can occur which will stop it working. If an error is given during the installation, retry the installation
and or download. Do NOT turn the unit off until an installation has completed correctly.
Once the installation has competed, if “Reboot after Install” is checked the unit will re-start with the new software installed. If not
checked then the unit should be turned off and on again manually.
NOTE: As part of the installation procedure, all memories are archived to a backup file and then deleted. They can be restored from the
System-Memories page using the Restore button and selecting the ‘_Before_Upgrade’ archive.
LOGGING
Logging allows events to be detected and recorded for future examination. The events to be logged can be specified so that unwanted
events do not appear in the event log. If a system has a problem with intermittent signals, the PHABRIX Sx can be connected to that
source and can be left for several days to log any errors. At the end of that period the log can be examined and the time and date of
each error noted.
The error log is saved when the unit is powered off and may be downloaded from the unit via FTP .
EVENTS LOG
The event log displays a list of events with a time stamp showing when they occurred. Pressing OK on the event log page allows the
event log to be scrolled through to view all events in the list. The currently selected event is shown on the event log header. The date
PHABRIX Sx Manual
Rev. 0.10.0043
Page 49
format may be changed using the Date ‘Format’ control on the System-Misc page. The event log may be cleared by pressing ‘Clear Log’
button; a dialog will be shown asking the user to confirm the action. A date stamped ‘mark’ may be inserted into the event log to allow
users to see when a test started or when a significant event happened using the ‘Add Mark in log’ button.
Note that the event log only shows changes in status, so if the input is always in error and never good, an event will not be
shown. To get the full state of the instrument will require looking at the current status as well as the event log.
EVENTS LOG SETUP
The events to be logged are set up on this page by checking the appropriate ‘Log’ checkboxes.
AUDIO THRESHOLDS
This section allows the thresholds for audio events to be set. If the audio level for a channel is higher than that specified for the Clip or
High fields for the number seconds specified then an event will be added to the event log. If the audio level for a channel is lower than
that specified for the Quiet or Muted fields, then and event will be added to the event log. VIDEO STATUS
OUTPUT STANDARD
A log event will be added whenever the generator video standard changes.
EDH/CRC
A log event will be added whenever a EDH/CRC error state changes. If the EDH/CRC state is correct, the event will show OK, else it will
show FAIL. Separate Luma and Chroma CRC events may be shown. Note that EDH/CRC events may occur when an SDI signal is
connected or removed.
INPUT STATUS
A log event will be added whenever the input video standard changes or if the input is lost or re-appears.
REFERENCE STATUS
PHABRIX Sx Manual
Rev. 0.10.0043
Page 50
A log event will be added whenever the external reference standard changes or the external reference input is lost or re-appears.
PICTURE CRC
This should only be used for static single frame test patterns (do not use for Zone Plate, dynamic broadcast signals or
CheckField/Pathalogical test patterns which are two frames long at HD). This can be used to log changes in the CRC for the active
picture (a value which is unique for each test pattern). If the CRC changes and was previously OK an error is added to the event log. If
the CRC is the same as the last frame for 5 seconds an OK event will be added to the event log. Thus, if the active picture CRC is
continuously changing there will only be one event in the log until the picture remains static when an OK event will be added.
This feature is useful for checking that equipment is not corrupting static test patterns.
AUDIO STATUS
ERRORS
A log event will be added whenever the embedded audio error status changes. This may be due to a Data Block Number error, ECC
error or phase error status change. The event entry will detail which state has changed.
DOLBY-E STATUS (REQUIRES DOLBY-E ANALYSIS OPTION)
ERRORS
This will add an event to the event log when a Dolby-E input stream is detected or lost. An event will also be added if a CRC error is
detected in the Dolby-E meta-data stream. If an error is detected in the Dolby-E stream, it may mean that the Dolby-E stream has not
been synchronised with the embedded audio clocks.
TIMING
An event will be added to the event log if the Dolby-E frame timing is outside the Dolby specified ‘Ideal’ range. A Warning event will be
given if the signal is OK but slightly outside the range and an Error event if it is on an invalid line.
COMMON METADATA
If any of the common meta-data (Program Configuration, Bit Depth, Frame Rates) changes, then the changed meta-data will be added
to the event log.
PROGRAM METADATA
If any of the program meta-data changes, then the changed meta-data will be added to the event log. This can be useful for following
changes to a program stream over a long period of transmission.
AES STATUS
ERRORS
PHABRIX Sx Manual
Rev. 0.10.0043
Page 51
A log event will be added whenever an error is detected in the AES input stream. This is only available on SxA/SxE units.
INPUT STATUS
A log event will be added whenever the AES input status changes. This is only available on SxA/SxE units.
LOGGING
This section controls ALL logging events
CLEAR
This clears all entries in the event log.
ENABLE
Logging is enabled using the Enable CheckBox. If this is not checked, no events will be added to the log. This is a simple method of
turning off ALL logging temporarily.
BEEP
If the ‘Beep’ CheckBox is checked, the Sx will emit a short tone when an Event is added to the log. Note that the beep will happen even
if the Speaker is set to Mute.
SYS ERRORS
The Sys Errors checkbox allows system errors to be displayed in the Event Log if they happen. If you are having problems with your Sx,
checking this box can add events that can help PHABRIX determine the nature of the problem.
SYSTEM INFO
The System Info checkbox allows system to report additional internal messages in the Event Log if they happen. If you are having
problems with your Sx, checking this box can add events that can help PHABRIX determine the nature of the problem.
BATTERY
The Battery checkbox allows the system to log the battery voltage. If you are having problems with your Sx, checking this box can add
events that can help PHABRIX determine the nature of the problem.
SAVE
The ‘Save’ button saves the current event log to a text file in the currently specified language. The log file created, logfile.txt may be
downloaded using a FTP connection.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 52
SPEAKER
The unit contains a single loud speaker and associated stereo headphone socket which can be connected to any of the audio input or
output channels or pairs.
The ‘Mute’ checkbox allows both signals to be muted.
A volume control is provided to adjust the level to headphones and speaker together. The balance control can be used to adjust the
Left-Right balance for the source being monitored.
The monitored source can be set to the input or output of the unit and the input and output sources can be set independently to either
a stereo pair or single audio channel.
The speaker can be muted when headphones are plugged in by checking the ‘Mute Spkr if Headphones’ control.
Note: When listening to an audio source, the SX needs the audio to be synchronous with the SX Generators’ audio. If this is
NOT the case, ‘clicks’ will be heard on the speaker. Either connect the SX reference to the same reference as the SDI input
source and set the Generator-GenLock source to Ref or set the genlock source to Input-1.
REMOTE FILE ACCESS
Files may be uploaded or downloaded from/to the PHABRIX Sx by a remote PC using either the USB connection or over Ethernet.
FTP
You will need an Ethernet cable to connect the unit to a PC.
To connect to the unit you will need to use a FTP client which may be a GUI
based one such as FileZilla or that built into windows. To log onto the system
you will need a login and password. The login for the system is ‘sxuser’ and
the password is ‘phabrixsx’.
‘FileZilla’ is available for download from
http://filezilla-project.org/download.php
PHABRIX Sx Manual
Rev. 0.10.0043
Page 53
Other FTP applications are available for other computer platforms. Once you have connected to the unit, you should be able to see the
unit file structure below. When downloading software revisions to the Sx, you must ensure that your FTP application is set to transfer
binary files without corrupting them. On FileZilla, this requires you to go to the “Edit - Settings” menu and select the Transfers – File
Types page. Make sure that the “Treat files without extension as ASCII file” check box is NOT checked or corruption will occur.
SX FILE STRUCTURE
Several directories are provided for user files these are:
PATTERNS
This directory contains several sub-directories for the related video standards. Test pattern files should be placed in the correct
directory for the video standard in use. i.e. if a 720p video standard is being used, only the test patterns in the 720yuv directory will be
available. You may have a test pattern with the same name in different pattern directories but they should have the correct size and
colour type (rgb/yuv) for the directory that they are in or they will be converted and may lose colour accuracy.
Patterns that are too large for the current standard will be clipped to fit; patterns that are too small will gain a black border and will be
centred on the output image.
Test patterns are .pat files for the standard line based pattern files or user files. Supported user file formats are:
•
Windows bitmap files (.bmp). We support 24bit uncompressed bitmap formats only.
•
10 bit video files (.dpx) We support 10bit RGB/YUV formats only in Left to Right orientation.
•
Yuv and qnt files (8/10 bit packed yuv only)
•
targa (.tg) files which are compressed or uncompressed 8bit RGB files. We support Left to Right orientation only.
Note that bitmap files which are RGB will be converted to YUV internally as appropriate to the output standard. This will mean that not
all valid YUV values can be output. If dpx YUV files are used then all valid values may be output.
PHABRIX Sx Manual
Rev. 0.10.0043
Page 54
SCRIPTS
Command scripts may be downloaded into this directory. See FileFormats-Command Scripts for more details.
SETUP
This directory contains the installer files for different releases of the software. Each release is comprised of a .tar.gz file and is self
contained. If a release of software is copied onto the unit, the list of available releases will be updated within a minute.
IDENTS
This contains bitmap idents as used by the generator. Supported user file formats are: .bmp (Windows bitmap files: 24bit only), dpx
files (10 bit video files) yuv files (8/10 bit packed yuv) and targa (.tga) files
Note that bitmap files are RGB and will be converted to YUV internally as appropriate to the output standard. This will mean that not all
valid YUV values can be output. If YUV files are used(.dpx), then all valid values may be output.
FONTS
The fonts available for use by the generator to add text idents may be enhanced by downloading new True Type fonts (.ttf) into this
directory.

FILE FORMATS
COMMAND SCRIPTS
Command scripts are text files with an file extension of .cmd. They are formatted with one step per line. The line is formatted as
StepTime, StepAction, StepParameters
StepTime is a numeric value in seconds 0....n
StepAction is one of:
ARCHIVE
This is used to specify the archive file to be loaded when the script is run. This makes sure that all the memories required for the test
have been loaded.
This archive file is loaded EVERY time the script is run so if you make changes to any memories you MUST use the
Export/Archive section on the System-Memories tab to backup the current memories.
LOADMEM,
Loads the memory specified in the StepParameters field – must be a numeric value 1...num memories.
CHECKERRS,
Check for errors in StepTime seconds. If there are any errors an event is added to the event log and the sequence pauses with a
message to continue or abort. If the SDI input signal is missing, this is treated as an error.CHECK_AP_CRC
Check for changes to the EDH active picture value in StepTime seconds. An event is added to the event log.
PROMPT
This will put a short prompt on screen in a dialog asking the operator a question and waiting for OK to be pressed to continue. The time
field is ignored and the parameter following is the text displayed.
CLEARLOG
This clears the Event Log
DISABLEEVT
This disables Event logging
ENABLEEVT
This enables Event logging
PHABRIX Sx Manual
Rev. 0.10.0043
Page 56
CLEARERRORS
This clears all error counts (EDH/CRC etc.)
LOGCOMMENT
Add the specified comment to the log file – useful to document the stage in the test process
PAUSE
Pause for the specified number of seconds to allow another process such as loading test patterns to complete.
SAVESTATUS
Save the current system status as an XML file.
SAVEIMAGE
Save the selected image as a bitmap file in the current scripts directory. Filename must be specified.
SELECTTAB
Show the selected tab to allow the user to view something.
SEL_USER
Select user – users are comma separated
CHECK_EYE
Checks that the eye amplitude and rise/fall times are within the SMPTE specifications for the time period specified.
CHECK_JITTER
Checks that the jitter levels are under those set in the logging jitter threshold fields for the time period specified. See logging setup
section for further details.
CHECK_METER_LEVEL
This action checks that the level for any visible meters is at the level set by the meter scale. This level may be -18dB or -20dB. If the level
is over 1dB greater or less than that value an error will be inserted in the log and report files. If any groups are missing, these will be
ignored by the test.
CHECK_AES_INP
This action checks that the AES input signal is present and has no errors for the specified time period.

The polynomial for the CRC is X + X + X + 1, with an initial value of all ones (0xFFFF).
The C code below shows the CRC algorithm being performed on 1920x1080 samples of YCC422-10 black. This will calculate a luminance
CRC (y_crc) of 0xB03E and a chrominance CRC (crc_c) of 0x714D.
#include <stdint.h>
#include <stdio.h>
#define IMAGE_SIZE (1920 * 1080)
static uint16_t calculate_crc_10(uint16_t crc, uint16_t d)
{
int bit;
int xor;
for (bit = 10; bit; bit--)
{
xor = (crc & 0x8000) ^ ((d & 0x200) << 6);
d <<= 1;
crc <<= 1;
if (xor)
crc ^= 0x1021;
/* the polynomial (post-shift) */
}
return (crc);
}
int main(void)
{
int i;
uint16_t crc_y = 0xFFFF;
uint16_t crc_c = 0xFFFF;
for (i = 0; i < IMAGE_SIZE; i++)
{
crc_y = calculate_crc_10(crc_y, 0x040);
crc_c = calculate_crc_10(crc_c, 0x200);
}
/* luma black value */
/* chroma black value */
printf("crc_y = 0x%04X\n", crc_y);
printf("crc_c = 0x%04X\n", crc_c);
return 0;
