Installation Environment
Operating Temperature
The unit should only be operated between 0 and 40 °Celsius. 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 internal
temperature rises above 65°Celsius the unit will turn OFF automatically.
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.
When Not In Use
Disconnect the unit from the power supply and AC power source when not in use.

Overview
Start up
Installation
The rear of the unit shown above describes the connections and interfaces of the Qx.
Before turning on the Qx, make sure the following connections are in place:
The XLR power cable is inserted.
For instrument display connect a suitable 1920 x 1080 capable monitor to either the HDMI instrument
output or the SDI instrument output. The monitor output can be configured for 1080p60, 1080p59.94
or 1080p50 frame rates using ‘Display Options’ submenu of the ‘Instrument Launch Menu’.
For mouse and keyboard control, the two USB ports at the rear of the unit should be used.
Note: The following interfaces are temporarily unavailable in this release of software:
• SFP A and SFP B
• LTC In
• GPI I/O
• AES I/O
Analyser SDI connections
Analyser
The Physical Layer connection for eye and jitter outlined in red is the furthest right BNC with a red nut.
This provides the multi rate eye and jitter connection from HD-SDI to 12G-SDI.
There are four 12G-SDI capable input BNC’s for the analyser SDI IN A, B, C, D.
Up to four SDI inputs may be connected at any one time however the system will automatically
determine the signal set to analyse be it single link, dual link or quad link based on the SMPTE ST 352
packets present. The algorithm looks to ‘SDI IN A’ first and then determines the overall standard.
If the SMPTE ST 352 packets are known to be incorrect then the user has the option to select ‘Ignore
payload identifier packets (ST 352)’ in the ‘Analyser Configuration’ window.

Generator SDI connections
The generator provides up to four SDI output signals which must form part of the same video signal set
e.g. 12G payload using four 3G-SDI outputs or 12G payload using two 6G-SDI signals.
‘SDI OUT A’ is always present and carries the first signal in the group. ‘SDI OUT B’ is active for dual link
standards and ‘SDI OUT C’ and ‘SDI OUT D’ are active for quad link standards.
Powering up the Qx
When the ‘Power Button’ on the Qx is first pressed, the unit fans will cycle for 20-30 seconds at high
speed as the system boots then settle to their normal operating speed.

As each instrument is selected, an icon will be placed on the ‘Instrument Bar’. The instrument and icon
will be assigned a colour. Each icon will glow in the assigned colour to indicate if it is part of a ‘group’ of
instruments related to analyser, generator, or system.
Instruments automatically group by colour. If one instrument is placed next to another then the border
will outline all instruments of a common group in contact with each other to aid group recognition.
Each instrument also has a sub menu. The sub menu is activated by right clicking the mouse in the
window enabling a drop down configuration menu. Click and drag on the grey bar at the top of the
sub menu to move it. In addition to window specific commands, the option to ‘Close’ the instrument is
provided in its sub menu.
Double clicking within a window will cycle through a set of standard instrument sizes. In many cases the
size of a window can be further adjusted to suit requirements. Click and drag on an instrument’s surface
to reposition the instrument.

Instrument Description
The guide that follows is intended as an introduction to the menu selection and the tool-set. The Qx has
the advantage of being a generator and an analyser so this tour of the product will be using both tool-
sets simultaneously.
For this guide we will assume that you have connected the unit to itself as shown in the following
diagram.

PHABRIX Qx Operation Manual

Generation
Generator - Configuration
The ‘Generator Configuration’ window is used to select the generator video standard and test pattern.
Once selected the new test signal is loaded by pressing the ‘Generate’ pane.
Note: In this software revision the generator takes approximately 8 seconds to load after which the eye
and jitter toolset will be enabled. During this period all other analyser functions are disabled.
Right clicking anywhere within the generator window brings up a configuration menu.
To simplify selection the generator standards list may be filtered using the following settings:
• Filter video standard list > Frame Rate > [No filter, 23.98, 24, 25, 29.97, 30, 47.95, 48, 50,
59.94, 60]
• Filter video standard list > Colour Format > [No filter, YCbCr:422, YCbCrA:4444, RGBA:4444,
YCbCr:444, RGB:444, YCbCrA:4224
• Filter video standard list > Bit depth > [No filter, 10, 12]
• Filter video standard list > Active Lines > [No filter, 720, 1080, 2160]
• Filter video standard list > Sub Image Format > [No filter, Single Image, square division, 2
Sampl...erleave]
• Filter video standard list > Level > [No filter, A, B]
• Filter video standard list > Combined SDI rate > [No filter, 1.5G, 3G, 6G, 12G]
• Filter video standard list > Source image width > [No filter, 1280, 1920, 2048, 3840, 4096]
• Filter video standard list > Interlace > [No filter, progressive, interlaced, segmented]
• Filter video standard list > Link Count > [No filter, 1, 2, 4]
• Filter video standard list > Transfer Curve > [No filter, SDR-TV, PQ]
Filters are removed by selecting in menu:
• Filter video standard list > Clear filters
Generator toolset border colour selection is provided for clear identification:
• Generator tools colour select, [colour]

PHABRIX Qx Operation Manual

Colour selection is via the HSV tool shown above using two cursors. The left hand colour rectangle
allows selection of hue (horizontal) and saturation (vertical). The right hand vertical bar selects
luminance.
Pathological signal insertion
Pathological Signal Insertion is a powerful feature.
In addition to selecting a background test pattern a pathological pattern may be added as an overlay.
• Pathological insertion, [Enabled, Disabled]
Three types of pattern are supported:
• Pathological insertion, Pattern to overlay, [EQ, PLL, CheckField]
The amount of pathological pattern may be configured to enable the user to verify how sensitive the SDI
link is to pathological conditions on the interface:
• Pathological insertion, Pairs to insert, [0 to 16384]
This control limits at the selected formats line length.
Note: Pathological signals are approved by SMPTE for use with HD and 3G level A standards only. For
3G level B, 6G and 12G-SDI interface formats pathological signals can still be used but are not approved
by SMPTE (as of February 2017). It is believed that inserting a full line of pathological signal in these
non-approved standards is too stressful a test for the SDI interface. No physical damage will occur but
the interface may exhibit reduced operating performance in the form of bit errors.
Output offset adjustment
A signal can be generated with a fixed offset relative to the system reference.
Offsets can be entered in temporal or spatial terms:
• Output offset adjustment > Offset Type > [Time, Lines And Pixels]
Selecting ‘Time’ reveals a drop down field where the timing offset can be set in microseconds:
• Output offset adjustment > Offset Type > Time > Output Time Offset > [0.00, +/- 0.01, etc...]
Selecting ‘Lines And Pixels’ reveals drop down fields where the offset can be set in these terms:
• Output offset adjustment > Offset Type > Lines And Pixels > Output Line Offset > [0 to +/-
(Total no. of Lines for current standard -1)]
• Output offset adjustment > Offset Type > Lines And Pixels > Output Pixel Offset >[0 to +/-
(Total no. of Pixels per Line for current standard -1)]
Generator offset is removed by selecting in menu:
• Output offset adjustment > Clear offsets

Generation
Generator - Status
The ‘Generator - Status’ menu shows the generator pattern selected and confirms the SDI OUT A, B,
C or D presence and Sub Image mapping information. This window is status only, there are no user
configurations.

PHABRIX Qx Operation Manual

System
System IO (SDI)
Due to the complexity of the UHDTV standards, PHABRIX has introduced innovative ways of displaying
status. This however does involve the information being displayed across several instruments. The
‘System IO (SDI)’ window has been designed as a quick view of the signal inputs and outputs attached to
the Qx.
Active SDI inputs and outputs are indicated by the coloured connectors. Greyed out connectors indicate
signals not present. The colour of the connectors corresponds to the colour of the instrument borders
and instrument icons to aid recognition.
The presence of external reference and its standard is also displayed graphically with a coloured
connector. If the system is set to lock to the external reference and a stable lock has been achieved, then
the inner ring of the EXT REF BNC pictured will be highlighted in Grey.
• BNC image: [Grey (reference connected), Red (error with reference), Black (no reference
connected]
Note: The EXT REF BNC shows the status of external reference only; which is not neccessarily the system
reference. System reference is selectable in the ‘Timing and System Reference’ instrument.
Below the graphical connector display is a table showing SDI input and output status, and external
reference standard and status. The external reference field displays the following states:
• EXT REF: [No Signal, Unstable, 525/59.94, 625/50, etc...]
If external reference is not currently being used as system reference, its field text will display in yellow.
When external reference is the system reference,this table field text will be white.

Analysis
Analyser - Configuration
The ‘Analyser - Configuration’ window controls the video standard being analysed. It lists the payloads
on the SDI input signals and highlights the ones used by the video standard being analysed.
The Payloads are identified primarily by ST-352 packets, if these are missing the signal stats will be
analysed and a best guess payload identifier will be listed.
Incorrect ST 352 packets are indicated in red within the ‘Analyser - Configuration’ window.
• Ignore Payload Identifier Packets (ST 352) > Checkbox [tick = ignore]
ST-352 packets can be ignored such that a best guess payload identifier is always used. Select the
“Ignore Payload Identifier Packets (ST-352)” option from the window’s menu.
• Analyser tools colour select > [colour]
Colour selection is via a HSV tool providing two cursors. The left hand colour rectangle allows
selection of hue (horizontal) and saturation (vertical). The right hand vertical bar selects luminance.

Analysis
Stats - SDI In A, B, C, D
‘Stats - SDI In A’, B, C and D provide information to verify the format of the signals being analysed. A
video signal may be comprised of up to four separate SDI signals hence four separate windows.
Example 1 shows the display of data from a single 12G input on input A
Example 2 shows the display of data from a quad 3G input hence 4 separate video status windows

Analysis
Analyser - Picture
The picture view shows the generator pattern currently being analysed by the Qx. The picture window
may default to full screen - simply right click to change the picture to SMALL or MEDIUM. Right click the
mouse to select MOVE to reposition the picture anywhere on the display.
The instrument’s right click submenu provides various setting, including the ability to confidence monitor
multi-sub-image video signals:
• Per Sub-Image Decimation > [Disabled, Enabled]
With this setting enabled, sub-images are decimated individually and recombined, allowing detection of
significant errors in individual sub-images (2SI only).
Note: The above setting will be available soon in a future software release.
Blanking Area
By right clicking with the mouse the operator can also enable ‘Show Blanking’. This will offset the picture
to the right revealing the blanking area.
• Show Blanking > [Disabled, Enabled]
Note: ‘Show Blanking’ is not available for multiple sub-image video standards as the active picture is
separated from the blanking regions during active picture reconstruction.

PHABRIX Qx Operation Manual
Page 13
HDR Heat-map (False Colour Overlay)
A false colour overlay can be applied to the picture view, to highlight areas of the image that are of
particular luminance.
The picture can be displayed in greyscale. If enabled at the same time as ‘False colour highlighting’,
all image elements outside of the enabled false colour overlay luminance range(s) will be displayed in
greyscale mode; leaving the false colour highlight elements to stand out more:
• Greyscale mode > [Enabled, Disabled]
A scale with numeric and graphic display of the luminance range(s) of the overlay in use, is available:
• False Colour Overlay Scale > [Enabled, Disabled]
The required luminance units for the scale can be selected:
• Luminance Measurement > [Decimal Level, PQ Nits]
Different types of false colour overlay may be applied to clearly visualise different image details, and a
custom mode is provided to allow the creation of a modified or bespoke overlay:
• False colour ranges > False Colour Highlighting > [Disabled, PQ HDR, SDR All Bands, SDR
Shadow, SDR Skin Tones, SDR Highlights, Out of Range, Custom]
The range(s) and colours of a selected false colour overlay can be modified by adjusting the 7 overlay
bands. Up to 7 distinct ranges can be simultaneously enabled in a single overlay. If adjusted, the new or
modified overlay will be designated as the ‘Custom’ overlay type.
