Getting Started
General Connections
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. Both display outputs carry the selected audio monitoring channel/pair. The
monitor output can be configured for 1080p60, 1080p59.94 or 1080p50 frame rates using the ‘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 interface is unavailable in this release of software:
l LTC In
SDI Connections
Introduced in this software release, a choice of two SDI connector types – BNC and SFP – is available for the
flow of SDI signals in and out of the Qx unit.
SDI Connection Configuration [SDI Modes]
Select the SDI connector configuration you require in the ‘System IO’ instrument submenu (‘SDI Input Source’
and ‘SDI Out’). A choice of two SDI connector types – BNC and SFP – is available.
The following combinations are available:
l BNC in / BNC out
l SFP in / SFP out
l BNC in / SFP out
l SFP in / BNC out
Note: The Qx default SDI connector state is BNC in / BNC out.
PHABRIX Qx User Manual Page 1
Note: Use SDI SFP's approved by PHABRIX. An error message window will appear on the Qx screen if an
incompatible SFP is inserted.
Page 2 PHABRIX Qx User Manual
SDI Input and Output Diagrams
INPUTS
BNC's: Lead with Input A
SFP's: Use any input
Note: It will take marginally longer for the Qx to lock to SDI Input signals received via SFP than those received
via BNC.
OUTPUTS
BNC's: ‘Output Copy’ optional
SFP's: Output copy functionality always on
Note: The Qx 'Loop' feature is available with SDI connector configuration BNC in / BNC out only.
PHABRIX Qx User Manual Page 3
SDI Inputs (BNC)
The Physical Layer input connection for eye and jitter is the rightmost BNC (when viewed from the rear) with a
red nut. This provides the multirate eye and jitter connection from 1.5G HD-SDI to 12G-SDI. There are four 12GSDI capable input BNCs for the analyzer: 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 analyze - 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 ‘Analyzer - Video Standard’ window.
This software release introduces SDIBNC In -to- SDI BNCOut signal passthrough via the 'Loop' feature in
'System IO', making the input SDIsignal(s) available on the SDI BNCoutput connection.
SDI Outputs (BNC)
The generator provides up to four SDI output signals which must form part of the same video signal set.
When 'SDI BNC Out - Generator Output Copy' mode' is enabled it will provide either:
l x4 single link
l x2 dual link
l x1 quad link
‘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.
If ‘Output Copy’ mode is not enabled, a single instance of a link standard will be generated:
l x1 single link
l x1 dual link
l x1 quad link
When the ‘Loop’ feature is enabled, the Qx generator wil be disabled, and instead, the SDI BNC Outputs will
be provided as output signals the SDI BNC Input signals the Qx is receiving. The 'SDI BNC Out - Loop SDI BNC
In' internal passthrough signal routing works as follows:
l ‘SDI BNC In A’ -> ‘SDI BNC Out A’
l ‘SDI BNC In B’ -> ‘SDI BNC Out B’
l ‘SDI BNC In C’ -> ‘SDI BNC Out C’
l ‘SDI BNC In D’ -> ‘SDI BNC Out D’
Note: The 'Output Copy' feature cannot be used at the same time as the 'Loop' feature. Enabling the 'Loop'
feature disables the generator activity on the SDI BNC outputs, and overrides 'Output Copy'.
Note: The 'Loop' feature is available when both the 'SDIInput Source' and 'SDI Out' are set to 'BNC' only.
('System IO' SDI connector configuration: BNC in / BNC out.)
SDI SFP Connections Overview
The Qx has two available SFP slots that can be used for SDI SFPs. These slot are labelled SFP+A and SFP+B.
Each slot can house an SFP that itself has one or two signal lanes.
The signal lane can either be an Rx (receiver/input) or Tx (transmitter/output).
Page 4 PHABRIX Qx User Manual
With two SDI SFPs inserted, between 2 to 4 SDI IOs via SFP are available. The number of these that are
inputs or outputs will depend on the SFP types that have been inserted. The Qx can take the following SFP
types in both SFP+A and B slots:
l RxRx (Dual Receiver – x2 Inputs)
l TxTx (Dual Transmitter – x2 Outputs)
l RxTx (Transceiver – x1 Input, x1 Output)
l Rx (Single Receiver - x1 Input)
l Tx (Single Transmitter - x1 Output)
An RxRx RxRx combination would provide x 4 inputs, TxTx TxTx provides x 4 outputs, Tx RxTx provides x 2
outputs and x 1 input, …and so on.
Installed SDI SFP signal lane positions are mapped to Qx system internal SDI paths as outlined below.
Whether a lane is an input or output is dependent on the SFP type installed:
SFP+ Slot Lane Position Qx Mapping 'System IO' Rear Image
SFP+A Left SDI IO A
(Input or Output depends on SFP
type. E.g. For an RxTx SFP in slot
SFP+A, this would be SDI In A.)
SFP+A Right SDI IO B
SFP+B Left SDI IO C
SFP+B Right SDI IO D
Note: Use SDI SFP's approved by PHABRIX. An error message window will appear on screen if an
incompatible SFP is inserted.
Note: See ‘Supported SFP List’ section of this manual for list of SFP’s approved by PHABRIX.
SDI Inputs (SFP)
Both SFP+A and SFP+B can be used as receive connections for SDI. Dependent on the SDI SFP types used,
up to x4 SDI input connections from 1.5G HD-SDI to 12G-SDI are available. The analyzer provides up to four
12G-SDI capable input: 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 analyze - be it single link, dual link, or quad link - based on the SMPTE ST 352 packets
present. The algorithm looks to the first available ‘SDI IN’ (in alphabetical order) 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 ‘Analyzer - Video Standard’ window.
PHABRIX Qx User Manual Page 5
Note:Use of SDISFP's for Eye and Jitter analysis and the 'Loop' signal passthrough feature is not supported.
SDI Outputs (SFP)
Both SFP+A and SFP+B can be used as transmit connections for SDI. Dependent on the SDI SFP types used,
up to x4 SDI output connections from 1.5G HD-SDI to 12G-SDI are available.
By default, internally, within the Qx, the generator provides four SDI output signals which must form part of the
same video signal set. Even when a single link standard is generated by a user, 'Generator Output Copy'
behaviour is implemented for SDISFP's automatically. The generator will provide either:
l x4 single link
l x2 dual link
l x1 quad link
On the internal SDI output signal paths of the Qx:
l a single link standard will always be carried on ‘SDI OUT A’, and then repeated on ‘SDI OUT B’, ‘SDI
OUT C’, and ‘SDI OUT D'
l a dual link standard... on ‘SDI OUT A’ and ‘SDI OUT B’, and then repeated on ‘SDI OUT C' and ‘SDI
OUT D'
l and a quad link standard will be delivered using all four outputs: ‘SDI OUT A’, ‘SDI OUT B’, ‘SDI OUT
C', and ‘SDI OUT D'
Which of these internal SDI output signal paths are utilized as externally available SDI outputs will depend on
the SFP types installed. See ‘SDI SFP Connections Overview' section of this manual for more details.
IP Connections
ST 2022-6 Input Optical SFP connection [Analyser - IP Mode]
The receive connection for IP video is SFP+A. This is the right hand most SFP when viewed from the rear.
This provides the multirate 2022-6 IP video analyzer connection from 1.5G HD-SDI to 3G-SDI over IP.
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 ‘Analyzer - Video Standard’ window.
ST 2022-6 Output Optical SFP connection [Generator - IP Mode]
The transmit connection for IP video is SFP+B. This is the left hand most SFP when viewed from the rear.This
provides the multirate 2022-6 IP video packet generation from 1.5G HD-SDI to 3G-SDI over IP.
Note: For both SFP+A and SFP+B, use optical SFP's approved by PHABRIX. Use of incompatible SFP's will
lead to an error message window appearing on the Qx screen when powered up.
LC to LC optical multi-mode duplex fiber cables should be used. Cables of the following specifications are
approved by PHABRIX: OM1 (62.5/125), OM2 (50/125), OM3 (50/125), and OM4 (50/125).

Instrument Description
The guide that follows is intended as an introduction to the menu selection and the toolset. The Qx has the
advantage of being a generator and an analyzer, so this tour of the product will be using both toolsets
simultaneously.
For this guide we will assume that you have connected the unit to itself as shown in the following diagram
for SDI (BNC or SFP) or IP optical SFP use. For dual link SDI standards also connect 'SDI OUT B' to 'SDI IN B',
and for quad link SDI standards, connect all four outputs SDI OUT A, B, C, D to SDI IN A, B, C, D respectively.

Generator - Configuration
The revamped 'Generator - Configuration' instrument has two tabs: one to select the generator video
standard and test pattern, and one for audio generation. in SDI Stress Toolset Mode, the ' Generate - Video'
submenu includes advanced generation tools which form part of the Advanced SDI Stress Toolset [PHQXOSDI-STRESS].
Generate - Video
[Qx 12G / PHQXO-GEN (QxIP)+PHQXO-UHD
(for 12G/6G-SDI on Qx IP)]
With a test pattern selected, click on your chosen video standard to generate it. A traffic light indicator will
turn yellow to show that generation is in progress. The light will turn green once the video standard has been
successfully generated.
Note: In this software revision the pattern may take up to 8 seconds to be generated.
The Qx provides video standard generation for a wide range of SDI rates, resolutions, frame rates, image
mappings, color gamuts, and transfer curves.
To simplify selection, the generator standards list may be filtered via drop down menus using the following
parameters:
l Type > [All, 12G 2-SI, QL 3G A 2-SI, QL 3G A SqDv, QL 3G B 2-SI, QL 3G B SqDv, DL 6G 2-SI, 6G 2-SI,

l Gamut > [All, 709, 2020, HLG 2020, PQ 2020, S-Log3 2020]
‘Recent history list…’ provides a list of the most recently generated video standard and test pattern
combinations. These can be quickly selected and regenerated from this drop down menu.
The ‘Status’ bar provides information on video generation progress.
Right-clicking anywhere within the 'Generate - Video' window brings up a configuration submenu.

User Test Patterns and Images
Users can add test images to the Qx. These user test files must be in the Tagged Image File Format (TIFF)
and of the exact pixel resolution of the video standard of intended use. The specifications for Qx user test
files are detailed below:
Format Type Extension Pixel Resolutions Bit Depth Pixel Order
TIFF Native
(Files converted to TIFF from
other formats are not supported)
.tif 1280x720,
1920x1080,
2048x1080,
3840x2160,
4096x2160
16 Interleaved
User test files can be added to the Qx via SFTP. See ‘Remote Connection’ section of this manual for details
on how to connect via SFTP to the Qx.
Via SFTP, user test files should added to the 'transfer/userTestPatterns' directory of the Qx. After adding
these files, restart the Qx. User test images will then be available in the 'Generate - Video' tab of 'Generator Configuration' alongside all other test patterns.
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.
l Pathological insertion > Insertion > [Enabled, Disabled]
Three types of pattern are supported:
l 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:
l Pathological insertion > Pairs to insert > [0 to 16384]
This control limits at the selected format’s 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 nonapproved 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 [SDI Modes]
A signal can be generated with a fixed offset, relative to the system reference.
Offsets can be entered in temporal or spatial terms:
l 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:
l 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 coordinate terms:
l Output offset adjustment > Offset Type > Lines And Pixels > Output Line Offset > [0 to +/- (Total no.
of Lines for current standard -1)]
l Output offset adjustment > Offset Type > Lines And Pixels > Pixel Offset > [0 to +/- (Total no. of Pixels
per Line for current standard -1)]
Page 16 PHABRIX Qx User Manual
Generator offset is removed by selecting in menu:
l Output offset adjustment > Clear offsets
Generate - Audio
[Qx 12G / PHQXO-GEN (Qx IP)]
32 channel audio generation is available in the 'Audio' tab of ‘Generator - Configuration’. In the instrument
submenu Audio Macros are provided for quick configuration, along with the ability to enable and disable
audio in individual sub images.
Depending on the generated video standard, up to 8 audio groups (32 channels) are available.
In the ‘Audio’ tab, audio Groups can be switched on and off as required, via checkboxes. Selecting the
arrow to the left hand side of a group reveals all the channels in that group. Clicking on the arrow again hides
these audio pairs.
Each channel can be configured by frequency and amplitude. Frequency can be set by music pitch or exact
tone frequency (Hz):

F 6, F♯/G♭ 6, G 6, G♯/A♭ 6, A 6, A♯/B♭ 6, B 6, C 7]
Amplitude levels can be adjusted in decibels relative to full scale (dBFS):
l Amplitude > [-144 dBFS to 0 dBFS]
For fast configuration, the submenu provides ‘Audio Macros’. The ‘Macro list’ contains pre-configured audio
channel setups which can be used or adapted for use:
l Audio Macros > Macro list > [Select…, Fixed Tone Ramp Levels, Fixed Tone fixed Level, Musical
Pitch Ramp Levels, Musical Pitch Fixed Levels]
When tone is fixed (i.e. ‘Fixed Tone Ramp Level’, ‘Fixed Tone Fixed Level’), or when ‘Select…’ is chosen,
to adjust frequency select:
l Audio Macros > Fixed frequency > [C 3, C♯/D♭ 3, D 3, D♯/E♭ 3, E 3, F 3, F♯/G♭ 3, G 3,

Advanced Generation Tools [SDI Stress Mode]
[SDI Stress Toolset Mode; PHQXO-SDI-STRESS+PHQX01E /
PHQX01E-IP / PHQXM-01E + PHQXO-GEN (Qx IP)]
As part of the Advanced SDI Stress Toolset [PHQXO-SDI-STRESS], advanced generation tools are now
available via the instrument submenu, in SDI Stress Toolset Mode. The toolset provides: control over SDI
scrambler switch-off, sync bit insertion, a PRBS (pseudo-random binary sequence) mode for end-to-end
bit error rate testing (BERT), advanced jitter generation controls –facilitating the generation and bespoke
adjustment of jitter measurement parameters, SDI output amplitude control, SDI output muting, and driver
pre-emphasis. These tools support a wide range of advanced testing and troubleshooting.
SDI Scrambler
The selected video standard data stream can be made to bypass the SMPTE scrambler, just prior to the
output stage. To bypass the scrambler, disabled it:
l Advanced Generation Tools (BNC) > SDI Scrambler > [Enabled, Disabled]
Note: For the generation of conventional video, the default state for the SDI Scrambler is ‘Enabled’.
Sync Bit Insertion (12G / 6G)
Sync bit insertion prevents the occurrence of a pathological condition that results in the removal of sync bits,
otherwise known as 'potholing'. Before the output, a sync bit is applied to the Timing Reference Signal (TRS)
and Ancillary Data Flag (ADF) words of the generated video standard. Sync Bit Insertion can be enabled and
disabled in the submenu:
l Advanced Generation Tools (BNC) > Sync Bit Insertion > [Enabled, Disabled]
Note: This feature applies only to 6G-SDI and 12G-SDI video standards.
Note: The insertion of the sync bit is observable in the video signal TRS and ADF words seen in AnalyserDataview when ‘Sync Bit Removal’ is disabled.
PRBS Mode
In addition to SDI test signal generation, for the stress testing of SDI infrastructure the Qx offers end-to-end
BERT capability, with the addition of PRBS generation and analysis tools.
A variety of PRBS signals can be generated:
l Advanced Generation Tools (BNC) > PRBS Mode > [Disabled, PRBS-7, PRBS-9, PRBS-15, PRBS-23,
PRBS-31]
Once selected, a PRBS signal can be inverted. Errors can also be inserted into the stream:
l Advanced Generation Tools (BNC) > PRBS Mode > PRBS Signal Inversion > [Enabled, Disabled]
l Advanced Generation Tools (BNC) > PRBS Mode > PRBS Error Insertion > [Enabled, Disabled]
Page 18 PHABRIX Qx User Manual
Note: Both the 'Generator - Video Standard' pane and the ‘Generator – Status’ instrument indicate
when a PRBS signal is being generated.
Note: PRBS signal analysis is available in the ‘PRBS – Analysis’ instrument window.
Jitter Insertion
Jitter can be inserted into any generated SDI signal in order to stress the interface and ensure that
receivers are compliant to SMPTE recommended practice. Sinusoidal jitter can be inserted with a
frequency ranging from 10Hz to 10MHz. Peak-to-peak jitter amplitude can be adjusted.
Enable jitter insertion:
l Advanced Generation Tools (BNC) > Jitter Insertion Mode > [Disabled, Sine]
Enabling jitter insertion reveals a setting for specifying the frequency of the jitter wave:
l Advanced Generation Tools (BNC) > Jitter Insertion Mode > Frequency > [1.0Hz to 10.0MHz]
Note: For precision setting adjustment and frequencies below 10Hz use the up/down arrow buttons or input
values via a USB keyboard.
Peak-to-peak jitter amplitude can be adjusted, with jitter amplitude measured in terms of signal Eye
Unit interval (UI):
l Advanced Generation Tools (BNC) > Jitter Insertion Mode > Amplitude P-P > [slider, 0.01 to 110.00 UI,
dependent on frequency]
WARNING: In this software release, SDI outputs B, C and D may be corrupted when jitter is inserted.
Note: Jitter can be observed in the ‘Eye – SDI In A’ and ‘Jitter – SDI In A’ instrument windows. For analysis,
apply filters and other settings in the Eye and Jitter instruments as required. (See ‘Eye – SDI In A’ and ‘Jitter –
SDI In A’ sections of this manual for information on analysis.)
Driver & Output Control
The signal amplitude of ‘SDI Out A’ can be increased or decreased by up to 10%:
l Advanced Generation Tools (BNC) > Driver A Amplitude Offset > [+/- 0, 2, 4, 6, 8, 10%]
Note: Qx units released prior to software release 2.3 will first require Driver A calibration. For instructions on
driver calibration, see 'Driver Calibration' section of this manual.
The ability to mute any of the SDI outputs is also provided:
l Advanced Generation Tools (BNC) > Mute SDI Output A > [Enabled, Disabled]
l Advanced Generation Tools (BNC) > Mute SDI Output B > [Enabled, Disabled]
l Advanced Generation Tools (BNC) > Mute SDI Output C > [Enabled, Disabled]
l Advanced Generation Tools (BNC) > Mute SDI Output D > [Enabled, Disabled]
For SDI Out A, driver pre-emphasis can be adjusted to boost the signal at the beginning of the rising edge of
the eye pattern to optimize signal integrity. (See 'Eye - SDI In A' instrument for eye pattern display.)
l Advanced Generation Tools (BNC) > Driver Pre-Emphasis > [Disabled, 0.5 dB, 1.0 dB, 1.5 dB]
With Driver Pre-Emphasis enabled, the pre-emphasis time constant can be left as default, or changed divided by 2, 4, or 8 - to adjust how long the signal is boosted for:
l Advanced Generation Tools (BNC) > Driver Pre-Emphasis > Time-Constant > [Default, Div 2, Div 4, Div
8]

Generation
Generator - Status
[Qx 12G / PHQXO-GEN (Qx IP)]
The ‘Generator - Status’ window confirms the generated Video Standard and Test Pattern details. The
window shows the generator pattern selected, or PRBS signal selected (available in SDI Stress Toolset
Mode), and confirms the BNC output (SDIModes only) or SFP output presence, and Sub Image/Full Image
mapping information. Audio Presence & Sub Image information is also displayed, along with Video
Reference, Output offset adjustment, and Jitter insertion (SDI Stress Toolset Mode) details. This window
provides status information only; there are no user settings to configure.
When pathological overlay is generated in ‘Generator – Configuration’, the Qx detects this for all SDI
outputs, and ‘Pathological PLL/s’ and ‘Pathological Eq/s’ will display the number of pathological events that
have been generated per second. As one pathological event is created per line this also indicates the
number of lines per second on which pathological conditions occur on the interface. The detection of a
pathological condition is available as a GPI output of the Qx, for use in triggering an external analyzer device.
Note: Pathological Rate/s counters are not displayed in PRBS Mode.

IP Transmit (SFP B) [IP Mode]
[PHQXO-IP-NGT+PHQXO-IP-ENC+PHQXO-GEN (Qx IP)]
The ‘IP Transmit (SFP B)’ window is used to transmit the currently generated video standard signal as IP
video packets.
The tool can be used to simulate IP video network packet jitter introduced under a variety of network
conditions by providing the ability to adjust the transmission distribution profile.
The histogram shows the interval timing distribution of the packets being generated (each second) - that is:
the number of packets being generated each second, against the deviation of each packet interval from
the expected interval time. Transmission status information and prompts are also displayed at the bottom
of the window, and hovering over this status information reveals a tooltip detailing the ‘Current Transmit
Parameters’. (See Network Settings below for more information.)
Right-clicking in the window reveals a submenu.
Packet transmission can be switched on and off:
l Transmit > [On, Off]
The type of distribution profile can be selected, and the range of transmission packet intervals can be
adjusted. The adjustments are displayed in real-time, in the transmission histogram.
l Distribution Range > [slider +/- 0...492 clks]
l Distribution > [Uniform, Gaussian]
The submenu also provides the option to plot the number of transmitted packets on the vertical axis, in
either linear or logarithmic scale:
l Y-Axis Scale > [Linear, Log10]
Network Settings
IP, UDP, MAC, and SSRC network settings for packet transmission are set in the submenu, and can be
entered by keyboard or via the on-screen keypad when ‘Transmit’ is ‘Off’.
Transmission can be either multicast or unicast. The multicast group destination IP address, or the IP address
of the receive device (in the case of unicast) should be set as the destination IP address; as required:
l Dst IP Addr > [set IP address]
Page 22 PHABRIX Qx User Manual
The destination MAC address should be set as required, to ‘Automatic’ for multicast, or ‘SFP A’ for unicast
transmission to the same Qx unit. For unicast transmission to another device, set to ‘Manual’, and then enter
below, the MAC address of the receive device (in the case of a direct connection) or the first switching
device in the path of the transmitting Qx (in the case of an indirect connection to the receive device).
l Dst MAC Addr > [Automatic, Manual, SFP A]
UDP parameters:
l Src UDP Port > [set UDP port number as required]
l Dst UDP Port > [set UDP port number as required]
A Synchronization source identifier (SSRC) can be set for Real-time Transport Protocol (RTP) stream
subscription if required:
l SSRC > [set ID if required]
Once required network settings have been entered, switch ‘On’ ‘Transmit’ to commence transmission.
Note: Ensure also, that you are generating a test signal for transmission in ‘Generator - Video Standard’.

System
System IO
Due to the complexity of the UHDTV standards, PHABRIX has introduced innovative ways of displaying
status. The ‘System IO’ window has been designed as a quick view of the signal inputs and outputs attached
to the Qx.
'System IO' shows the status of signal inputs and outputs, external reference, cable length, and connector
details. In SDImodes, this status and configuration window provides input and output mechanism selection be it BNC or SFP. Additionally for SDI BNC outputs, 'System IO' offers a 'Generator Output Copy' option
(output copy is automatically applied for SDI SFPs), and the ability via the 'Loop' feature to passthrough the
SDIBNC input signal(s) - making it available on the SDI BNC output connection.
SDI Modes
In the top half of the instrument window is a graphical view of the Qx rear panel, displaying from left to right:
SDI BNC outputs, SDI BNC inputs, external reference, and SFP+B and SFP+A positions (and the I/O's of any
installed SFP's.)
All active SDI inputs and outputs are indicated by colored connectors; their colors dictated by the
Analyser/Generator color scheme set in 'Display Options'. (See 'Instrument Launch Menu' section of this
manual for more details.) An entirely grayed out connector indicates that a signal is not present, and the
previously colored ring will be black. The color of the connectors correspond to the color of their related
instrument borders and instrument icons, to aid recognition.
If an SDI SFP is unseated or not present, this is displayed graphically with a black void - indicating a missing
SFP. (IP SFP's will also be displayed if installed, but will only become active in IP boot up mode.)
The Qx SDIsignal input and output mechanism can be configured in the instrument submenu - with a choice
of two SDI connector types for both input and output.
Select the SDI connector configuration you require:
l SDI Input Source > [BNC, SFP]
l SDI Out > [BNC, SFP]
Note: The Qx default SDI connector state is BNC in / BNC out.
Example 1 shows a BNC output and BNC input in use
Page 24 PHABRIX Qx User Manual
Example 2 shows SFP outputs and SFP inputs in use
Note: BNC in / SFP out and SFP in / BNCout combinations are also supported
Note: For further details on SDI SFP input and output positioning, see 'SDI SFP Connections Overview'
section of this manual.
Additional SDIBNC output control is provided in the instrument submenu.
To duplicate output of the generated single link or dual link video standard on all unused SDI Out BNCs,
enable 'Output Copy':
l SDI BNC Out - Generator Output Copy > [Enabled, Disabled]
Note: This feature is not applicable to quad link standards
Note: Output copy functionality is automatically applied when using SDI SFP outputs
Signals presented to the SDI BNC Inputs of the Qx can be repeated out on the SDI BNC outputs of the unit,
by enabling the 'Loop' feature:
l SDI BNC Out - Loop SDI BNC In > [Enabled, Disabled]
When this 'Loop' feature is activated, there is a one-to-one mapping between the A, B, C, and D, inputs and
outputs respectively.
When enabled, the 'Loop' feature disables the generator activity on the SDI BNC outputs, and overrides
'Output Copy'.
Note: the 'Loop' feature is available in a BNC in / BNC out configuration only
The presence of external reference and its standard, is also displayed graphically with a colored 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 gray. The following ‘EXT REF’ BNC colors relate to
various external reference status:
l Gray (reference connected)
l Red (error with reference)
l Black (no reference connected)
Note: The EXT REF BNC shows the status of external reference only; which is not necessarily the system
reference. Overall system reference is selectable in the ‘Timing and System Reference’ instrument window.
Below the graphical connector display, are tables showing input and output status, cable length, external
reference standard and status, and SFP type and presence information. Hovering over the external reference
and SFP status information reveals tooltips containing additional status details.
The external reference table displays the following states:
l EXT REF: [No Signal, Unstable, 525/59.94, 625/50, etc...]
PHABRIX Qx User Manual Page 25
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.
Cable length measurements are displayed for each SDI BNC input. To measure the length of a connected
cable, be sure to first select the correct cable type from the instrument submenu:
l Cable Type > [Belden 8281, Belden 1505, Belden 1694A, Belden 1855A, Canare L5CFB, Image 1000]
The selected cable type is shown below the 'SDI In' BNC connector view.
Note: Cable measurements accurate to approximately +/- 10 meters.
IP Mode
Active IP SFP receive inputs and transmit outputs are indicated by colored connectors. The color of the
connectors corresponds to the color of their related instrument borders and instrument icons, to aid
recognition.
An entirely grayed out connector indicates that a signal is not present. If an SFP is unseated or not present,
this is displayed graphically with a black void - indicating a missing SFP.
SFP type and presence information is shown in tables, as are external reference standard and status
details; as per the SDI version of this UI.

AES IO Config
The Qx provides powerful and highly flexible functionality in the treatment of AES input and output signals
when present on pins 1-4 of the rear panel 26-way D-type connector.
(See ‘Specifications’ section of this manual for more details. A D-type to BNC converter can be employed to
provide user access to the AES I/O's.)
The ‘AES IO Config’ window provides an interface where a user can configure the AES I/Os as required:
l Up to 4 AES signals (a combination of inputs and/or outputs) can be handled at the same time
l SDI Input to AES Output audio conversion is available for both PCM and Dolby encoded audio (using
‘Transmit - Analyzer’)
l AES Input signals can be routed to other AES outputs providing a single loop output or up to 3 copy
outputs (using ‘Transmit - Passthrough’)
The window provides a graphical display of the 26-way D-type rear panel connector of the Qx, and labels the
AES pins (pins 1-4). The 'AES Panel' graphic shows the AES I/O BNCs in any AES breakout board connected
to the Qx rear panel D-type connector.
In both graphics, when an AES I/O is active it will glow in the Analyzer color when it is an AES Input (in
'Receive' mode) or the Generator color when it is an AES Output (in 'Transmit' mode).
In the lower half of the window, a table shows the status of each AES I/O. For AES Outputs the table also
shows the transmit mode source. Audio transmit source issues are highlighted in the table text:
l Red (configuration error), Yellow (audio source not present)
Hovering over the text reveals a tooltip outlining how to fix the issue.
Configuration of the AES I/O's is carried out in the instrument submenu.
Each AES I/O can be set as an input (receive), or output (transmit):
l Off: AES I/O is switched off
l Receive: I/O is set to AES Input
l Transmit - Generator: I/O is set to AES Output
PHABRIX Qx User Manual Page 27
The output audio signal source is the Qx audio generator (See ‘Audio’ tab of ‘Generator –
Configuration’ instrument.)
l Transmit - Analyzer: I/O is set to AES Output
The output audio signal comes from Image/Sub-image 1 of the Qx analyzer input (SDIor IP
2022-6)
l Transmit - Passthrough: I/O is set to AES Output
The output audio signal is routed from the chosen AES input ‘Passthrough Source’

The ‘Analyzer - Video Standard’ window displays the payloads of the video standard being analyzed. It
lists the payloads on SDI (SDI Modes) / 2022-6 SFP (IP Mode) input signals. The lower pane provides a
summary of the standard and of any analyzer overrides set.
The Payloads are identified primarily by ST-352 packets - if these are missing the signal stats will be
analyzed and a best guess payload identifier will be listed.
Unstable payloads, or those with damaged or missing ST 352 packets are indicated within the ‘Analyzer Video Standard’ window. Payload identifier errors are shown in red, warnings are indicated in yellow.
Ignore Payload Identifier Packets (ST 352)
ST-352 packets can be ignored such that a best guess payload identifier is used.
Page 28 PHABRIX Qx User Manual
In situations where the accuracy of incoming ST-352 packets cannot be relied upon, the instrument can
be forced to ignore the ST-352 packets, and image parameter overrides can be set by the user. To
ignore incoming ST-352 packets enable ‘Ignore Payload Identifier Packets (ST-352)’ in the submenu.
l Ignore Payload Identifier Packets (ST 352) > [Enabled, Disabled]
Payloads with ignored ST 352 packets are indicated within the ‘Analyzer - Video Standard’ window.
Transfer Curve and Colorimetry Overrides
HDR content may still contain the SMPTE payload ID for SDR and Rec.709 color space (as ‘standard’).
Therefore, when analyzing HDR and WCG (Wide Color Gamut) content, overrides can be enabled for the
appropriate HDR transfer curve and color space:
l Enable Transfer Curve Override > [Enabled, Disabled]
l Transfer Curve Override > [SDR-TV, HLG, PQ, S-Log3]
l Enable Colorimetry Override > [Enabled, Disabled]
l Colorimetry Override > [Rec.709, Rec.2020]
Sub Image Pixel Mapping Format Override
Where sub image format signals are delivered without ST-352 packet payload IDs or with mislabeled sub
image mapping information, e.g. if 2 sample interleave (2-SI) signal content is delivered incorrectly as square
division (SQ), it is necessary to be able to override the erroneous mapping in order to display the content
correctly.
l Enable Sub Image Pixel Mapping Format Override > [Enabled, Disabled]
l Sub Image Pixel Mapping Format Override > [2 Sampl...erleave, Square Division]
Note: The resulting effects of enabled overrides will be reflected in other image analyzer instruments within
the Qx Analyzer instrument toolset.

IP Receive Interpacket Timing (SFP A) [IP Mode]
[PHQXO-IP-NAT+PHQXO-IP-DEC (Qx 12G)]
The instrument provides analysis of IP media packet reception, and gives a real-time indication as to the
health of the received signal.
The histogram displays the distribution of all packet arrival intervals within a given second - the mean,
minimum, and maximum packet intervals for this period are also displayed. Outlier times significantly longer
than the expected mean, indicate significant delays in packet propagation. A high occurrence of such long
intervals characterizes high jitter in a network.

Eye - SDI in A [SDI Modes]
PHQX01E / PHQX01E-IP / PHQXM-01E]
One of the unique features of the Qx is the PHYSICAL layer analysis toolset. The Qx contains fundamental
technology developed and patented by PHABRIX which makes it unique where physical layer compliance
measurements are required up to 12 Gbps.
The Qx employs an analog front end providing in excess of 30 GHz bandwidth (5th harmonic of the 6GHz
fundamental for 12G-SDI). Featuring PHABRIX RealTime Eye RTE™, the Qx provides broadcast engineers
with a reliable, instantaneous physical layer display with automatic measurements to SMPTE standards.
The Qx enables measurement of both overshoot and undershoot along with amplitude, rise time, fall time
and delta - compulsory when testing against SMPTE standards. Accurate measurements are obtained within
seconds of connecting an SDI signal, making for a very fast system testing solution. Out of specification
measurements are indicated in red.
Example 1: 12G-SDI Eye pattern display with 100 kHz jitter filter
Example 2: 3G-SDI Eye pattern display with 100 kHz jitter filter
Note: ‘SDI In A’ has a red nut to indicate it is the SDI BNC that has the eye and jitter circuitry behind it
Note: The use of SFPinputs with the ‘Eye - SDI In A’ toolset is not supported

Analyzer - Dataview
This instrument displays the raw data present in the signal, be it - 1.5G HD-SDI, 3G-SDI, 6G-SDI, 12G-SDI or
2022-6. The data can be observed in hexadecimal, decimal, or binary formats, and each data word has a
sample & line co-ordinate. The instrument displays the entire video frame complete with active video, TRS
words, and blanking information. Changing the window size changes the amount of data displayed. For
6G-SDI and 12G-SDI video standards, pre-imposed sync bit correction is provided.
Data is presented with a color coding for both text and background:
l Foreground color indicates video sample type: Y (white), Cb (blue), Cr (red)
l Background color indicates data type: TRS words (blue), Blanking (black), Active picture (green)
The user can quickly navigate the dataview window using
sample and line selection in the 'Cursor' tool or using the
'Navigate' keypad.
Both tools are dynamically linked to an enabled 'Picture Cursor'
in the Waveform and Picture instruments.
The Cursor tool provides transport line and sample sliders to
move around the dataview, at the same time as giving the
corresponding Active Picture line and pixel values.
The 'Navigate' keypad (shown, right) allows the user to enter
the co-ordinates they want, and has buttons for quick
navigation to key locations: first and last samples or lines, end
of active video (EAV) and start of active video (SAV) TRS
words, active picture (AP) furthest - left, right, top, and bottom
positions.
The following right-click submenu options are presented:
l Cursor > Source > Line > [1 to Total no. of Lines for current standard]
l Cursor > Source > Sample > [1 to Total no. of Lines for current standard]

SDI A vs System Reference / Decapsulated vs System Reference
This section of the instrument displays the timing difference between the SDI A input signal (or Decapsulated
input - IP Mode) and the system reference the Qx is locked to. Both graphic and numeric (spatial and
temporal) values are presented by the instrument for this measurement. A relative timing bar tool dynamically
measures the timing of the input (white triangle) against the system reference (centrally fixed black vertical
crosshair).
The tool can be adjusted to display readings at frame scale, or zoom in all the way to a fraction of a line:
l Reference Timing Meter Range > [+/- 0.1 line, +/- 0.5 line, +/- 0.5 frame]
Input Measurement Offset
In addition to measurement of the input against absolute system reference, a system reference offset can
also be applied in the tool to measure against. The offset position is indicated on the relative timing bar tool
with a black triangle.
Offsets can be entered in temporal or spatial terms:
l Input Measurement Offset Type > [Time, Lines And Pixels]
Selecting ‘Time’ reveals a drop-down field where the timing offset can be set in microseconds:
l Input Measurement Offset Type > Time > Input Measurement Time Offset > [0.00, +/- 0.01, etc...]
Selecting ‘Lines And Pixels’ reveals drop-down fields where the offset can be set in these terms:
l Input Measurement Offset Type > Lines And Pixels > Input Measurement Line Offset > [0 to +/- (Total
no. of Lines for current standard -1)]
l Input Measurement Offset Type > Lines And Pixels >Input Measurement Pixel Offset > [0 to +/- (Total
no. of Pixels per Line for current standard -1)]
The input measurement offset can be set to the same position as the current ‘SDI In A’ (or ‘Decapsulated’ - IP
Mode) signal:
l Set Input Measurement Offset to current
The input measurement offset is removed by selecting in menu:
l Clear Input Measurement Offset
SDI Co-Timing [SDI Mode]
Many of the standards associated with UHDTV are a combination of signals to form the image plane.
Relative timing tools indicate that the quad or dual elements creating the single picture are correctly aligned

Color coded signal conditions - present, lost, and error are all available. Additional data is displayed as the
instrument is resized.
In addition to the option of a combined view, this software revision introduces tabs for separate 'Grid' and
'List' views of the ancillary data.
One view, Grid, gives a high level overview of packets present.
In the other 'List View' tab headings can be expanded, allowing for a granular drill down of discovered
ancillary packets – providing info on presence, checksum, Parity, and DBN. Packets can also be selected
here for ‘Analyzer – Ancillary Inspector’ analysis.
Colour coding provides further health info at a glance:
l White - Indicates ANC packets present and correct
l Red - Indicates ANC packets present but in error
l Yellow - indicates ANC packets present and correct but there has been a previous error
From the submenu – accessible in all views - ancillary status analysis can be reset:

results display area, and the trigger state will lapse to ‘None’.
If the trigger had been set to ‘Continuous’, it will remain in this state after successful detection, and will
continuously cause the display to refresh with the results of the next successful detection.
In addition to the ‘Identifier’, other inspection parameters pertaining to data search location can be set
including: Sub Image, Lines, HANC/VANC, and luma or chroma stream (Y-Pos/C-Pos):
l Sub Image > [Any, Sub Image 1, Sub Image 2, Sub Image 3, Sub Image 4, Sub Ima… Link B, Sub Ima…
Link B, Sub Ima… Link B, Sub Ima… Link B]
l Lines > [Any, Inside Range, Outside Range]
l HANC/VANC > [Both, HANC, VANC]
l Y-Pos/C-Pos > [Both, Y-Pos, C-Pos]
Additional parameters can be set to trigger only if errors are present, and the specific error types for the
trigger can be set to include: Checksum, DBN, Parity, and ANC Gap errors:
l Triggers only on Errors > [Enabled, Disabled]
l Triggers only on Errors > Enabled > Checksum Errors > [Enabled, Disabled]
l Triggers only on Errors > Enabled > DBN Errors > [Enabled, Disabled]
l Triggers only on Errors > Enabled > Parity Errors > [Enabled, Disabled]
l Triggers only on Errors > Enabled > Anc Gap Errors > [Enabled, Disabled]
When setting any parameters in ANC Inspector, AND logic applies; so note that ALL active search
parameters will have to be met before ANC Inspector can successfully display results of that search. If
Ancillary packet data in the analysed SDI data does not meet even one of the search conditions set, it will
not be displayed.
In searching for specific data events it is advisable to keep the search parameters as wide as possible to
first establish that you are actually seeing data for the selected ANC packet. Only when the ANC Inspector is
displaying streaming data, should you introduce more specific search parameters.
ANC Inspector can also be used to search more generally for errors with ‘Trigger only on Errors’ enabled
(and ‘Identifier’ set to ‘Any’). Where an error is present in a packet, individual data word text will become red
in the display indicating the exact position of an error within a packet.

A REST API remote connection can be established by enabling ‘REST API’ in the submenu:
l REST API > [Disabled, Enabled]
Page 56 PHABRIX Qx User Manual
The ‘Qx Network & Automation’ window contains all the information on the Qx that is needed in order to
send it a REST request. ‘IP Address’ (or ‘mDNS Hostname’ if your client’s host supports it) should be used as
the recipient of the request, and ‘REST API Port’ is the port that requests will need to be directed towards.
Note: The mDNS Hostname is composed of qx-<serial number>.local e.g. qx-123456.local and is case
insensitive.
The REST API supports four HTTP methods: GET, PUT, DELETE, and POST.
GET requests can be used to retrieve Qx information and navigate the submenus. PUT requests can be
used to modify and control Qx behavior and actions.
A web browser can be used to retrieve Information from the Qx with GET requests.
Any HTTP/1.1 compliant application can be used to control the Qx with both GET and PUT requests.
PUT, GET, DELETE, and POST requests can be scripted for automated testing.

Driver Calibration
[PHQX01E / PHQX01E-IP / PHQXM-01E]
Note: All PHABRIX units are calibrated and verified prior to dispatch. Over time however, the SDI generator
outputs of the Qx may require recalibration.
On units with PHABRIX RTE™ (RealTime Eye) capability, the SDI generator outputs of the Qx can each be
calibrated using the SDI A Input of the Qx.
Note: Recalibration relies upon the calibration status of the Eye/Jitter analyzer. If in doubt consider returning
the unit to PHABRIX for calibration.
Warning: Before attempting Qx calibration, be sure to that you are using a 12G cable of the specification
described below. If in doubt, do not attempt to perform calibration on your unit.
SDI Output Calibration Steps
Calibration can be performed by first, connecting a 1 meter long cable between SDI A Input and the SDI
Output to be calibrated. A 12G-SDI grade or compatible cable with 12G-SDI BNCs must be used. Suitable
cable types include: Canare L-5.5CUHD, and Belden 1694A.
Note: If the Qx is in ‘SDI Stress Toolset’ mode, first disable ‘Jitter Insertion Mode’ before beginning driver
calibration. See ‘Advanced Generation Tools’ section of this manual for further details.
Next, from the ‘Instrument Launch Menu’, selecting ‘System Settings > Driver Calibration > Driver Calibration’
opens a calibration window.
A drop-down menu allows the selection of the output to be calibrated. For SDI Output A, select Driver A, etc.
Select ‘Start’ to begin calibration. The calibration of an output should take 2-5 minutes.
Once SDI Output A is calibrated, connect the output side of the cable to SDI Output B and repeat the process
outlined above, until all Qx SDI Outputs have been calibrated.
It may take approximately 20 minutes to calibrate all four outputs.
