OPERATION
TURNING THE UNIT ON OR OFF
To turn on your PHA RIX Sx press the red button at the top right hand side of the unit.
Once the system has started, pressing the button for a few seconds 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 2 and 4 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, AES input status, genlock status, battery status and
current time. 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.
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 AES input status will be shown in red if there is no input
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 default 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.

ANAL SER
EYE
In the standard SxE this screen provides a 3-eye display along with continuous automatic measurements for:
•Amplitude
•Rise time
•Fall time
•Rise/fall difference
•Rising edge overshoot
•Falling edge overshoot
•Cable length
Any measurements which exceed the specification of the SDI signal are indicated in RED whilst valid parameters are displayed in WHITE.
The rise and fall time measurements are specified as the time between the 20% and 80% points on the eye waveform.
The cable length display is only an approximate value with 10m resolution thus a 5m cable will be shown as 0m long. The cable type
affects the length displayed which has been calibrated for elden 1694A cables.
The eye display is only accurate when connected via a 1m cable, if a longer cable is used the eye will begin to ‘close up’ and
measurements will become harder to perform. Note that the eye display is of the signal pre-equaliser, the equalizer in a system being
used to compensate for long cable lengths. There is no method for the SxE to view the signal post-equaliser.
Jitter-1: Selects either Timing or Alignment Jitter filters. Jitter filter selection affects both the jitter thermometer and eye pattern
displays. Timing and Alignment jitter filters are defined in the relevant SMPTE publication. The thermometer automatically calibrates to
the specification of the video standard and chosen filter. When reading is in specification the thermometer bar is GREEN, when close to
specification it is YELLOW, and when out of specification it’s RED.

ADVANCED ANALYSIS FEATURES (OPTIONAL EXTRA)
The Advanced Analysis option provides the user with additional tools on the Eye display to help determine the nature of jitter present
in SDI signals.
Histogram: Amp/Timing/ oth. Histograms enable the operator to observe the distribution of samples in both amplitude (Amp)
and time (Time). The amplitude histogram shows the distribution of samples over the complete visible eye picture.
The time histogram shows the distribution of samples at the zero point of the eye waveform for two thirds of the
visible time period.
Note: The time histogram overlays some of the automatic measurement display. The measurements may still be read
by Remote Control if purchased.
Jitter-1: Timing/Align/10Hz/100 Hz/1KHz/10KHz/100KHz. This filter operates on both the left hand jitter thermometer and the
eye waveform. The different filters enable the operator to understand more fully the nature of any jitter present.
When in Timing or Alignment modes, the meter range is set to show appropriate ranges for the SMPTE specification at
the current video input standard. When in other filter modes, the meter ranges are expanded so that larger ranges
may be viewed.
Jitter-2: This is a second jitter measurement thermometer and may be set to Timing/Align/10Hz/100Hz/1KHz/10KHz/100KHz.
This filter operates on just the right hand jitter thermometer. When in Timing or Alignment modes, the meter range is
set to show appropriate ranges for the SMPTE specification at the current video input standard. When in other filter
modes, the meter ranges are expanded so that larger ranges may be viewed.
Update: This allows selection of the update rate to allow longer display persistence. This may be set to 40ms (normal use) or
infinite. When set to infinite, the Run and Clear buttons are enabled.
Run: This check box stops the display from updating so that a waveform may be investigated in more detail. It is only
enabled when the update mode is set to infinite update mode.
Clear: This button clears the eye display. It is only enabled when the update mode is set to infinite update mode.

# Eyes: 1/2/3/4/5/10/20/H/2H/V/2V. This parameter adjusts the number of eyes visible on the eye display. The 10 and 20
modes are useful for observing serial-parallel conversion jitter, the H, 2H, V, and 2V are useful for observing the
effects of power supply born video synchronous noise in SDI signals. (H/2H/V/2V not yet implemented)
JITTER (OPTIONAL EXTRA)
The Advanced Analysis package provides a jitter display. This screen shows a trace of jitter amplitude versus time along with two jitter
thermometers and has the following controls:
Jitter-1: Timing/Align/10Hz/100Hz/1KHz/10KHz/100KHz. This filter operates on both the left hand jitter thermometer and the
jitter trace.
Jitter-2: Timing/Align/10Hz/100Hz/1KHz/10KHz/100KHz. This filter operates on just the right hand jitter thermometer.
Horiz: H/2H/V/Frame – horizontal sweep control for jitter trace.
UI/div: 0.1/0.2/0.5/1.0 – vertical gain control for the sweep trace.
Update: This allows selection of the update rate to allow longer display persistence. This may be set to 40ms (normal use) or
infinite. When set to infinite, the Run and Clear buttons are enabled.
Run: This check box stops the display from updating so that a waveform may be investigated in more detail. It is only
enabled when the update mode is set to infinite update mode.
Clear: This button clears the eye display. It is only enabled when the update mode is set to infinite update mode.

S STEM WIDE SETTINGS
MEMORIES
On the SxE, an additional check-box ‘Eye Jitter’ is available for the analyser section. This allows memories with just Eye Jitter settings to
be stored.
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 PHA RIX 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 .
LOG EYE JITTER

PHA RIX Sx Manual August 21, 2009 Page 10
The events to be logged are set up on this page by checking the appropriate ‘Log’ checkboxes.
JITTER THRESHOLDS
The jitter level at which an event is added may be set independently for each meter. (Only one meter provided as standard) This allows
you to set the maximum allowed jitter level and then test for invalid values over a period of time.
EYE TIMINGS
If checked, these controls will enable logging of invalid timing values. An event will be logged if the value exceeds the valid SMPTE range
and an event will be logged when the signal becomes valid again.
EYE AMPLITUDE
If checked, these controls will enable logging of invalid amplitude or over-shoot/undershoot values. An event will be logged if the value
exceeds the valid SMPTE range and an event will be logged when the signal becomes valid again.
