PeRT3 Eagle User Manual Version 1.6
Chapter 1: Overview
The LeCroy PeRT3 Eagle Test System is a new tool for testing of transceivers and other
serial data communication devices and systems. Verifying device performance to current
serial data standards normally requires multiple tools and multiple test setups, in order to
test the devices over the entire range of requirements, from signal quality and BER
testing through to protocol level error rate verification. With the LeCroy PeRT
entire process can be accomplished quickly and easily, using a single tool and a single
experimental setup, on multiple lanes of a serial communication link.
The PeRT
3
Eagle System is the first “protocol enabled” transceiver tester, allowing the
system to run not only electrical testing and error ratio testing, but also to control the
device under test during test operation. This allows further testing under live traffic
conditions since the PeRT
3
Eagle can communicate directly with the device, generating
actual traffic to exercise the device, which then can be used to measure protocol-level
error ratios.
3
PeRT
stands for Protocol enabled Receiver and Transmitter Tolerance Tester.
The PeRT
3
Eagle combines the electrical test properties of jitter testers, the bit error ratio
testing of BERTs, and the high level protocol packet error ratio testing of protocol
exercisers. All of this is accomplished with a single system and single setup.
The PeRT
3
Eagle System has an
integrated design, combining
digital electronics and signal
processing with an analog front
end. The PeRT
3
Eagle digital
subsystem provides
programmability, protocol
awareness, and digital test pattern
generation. The analog front end
provides advanced high quality
signal generation with precise
timing control, and the ability to produce a controlled signal waveform with
user-controlled jitter levels, amplitude modulation and other electrical stress generation.
The analog front end superimposes these signal impairments on the outgoing signal to
exercise and test the receiver channel of the device under test.
The PeRT
3
Eagle System provides the ability to control and modulate the outgoing test
signal. Test capabilities include modulation of clock noise and jitter, signal shaping (such
as amplitude control, rise/fall generation), pre- and de-emphasis, and also the ability to
monitor the signal quality of the traffic returned from the test device.
The “protocol-enabled” capabilities of the PeRT
3
Eagle also allow the system to manage
protocol-specific issues that confuse less sophisticated test systems. An example is the
resynchronization of clocks in SATA systems through the use of the ALIGN primitives.
The PeRT
3
Eagle can monitor and record protocol-level errors such as CRC errors, and
protocol-specific errors such as R_ERR in SATA.

The PeRT3 Eagle is able to: (1) generate patterns which produce standardized tests such
as PRBS; (2) generate protocol-level commands, which can be used both to control the
device under test (e.g., to put the device into a loop-back self-test mode, or request
information from the device on errors detected by the device); and (3) provide testing
under live traffic conditions while the PeRT

Note: PeRT
The PeRT3 Eagle provides coaxial SMA connectors to maintain signal integrity between
the device under test (DUT) and the test system. A separate SMA connector is provided
for each conductor in the differential pair (i.e., two connectors per line, four connectors
per bi-directional channel). The nature of the connection to the DUT will vary depending
on the specifics of the DUT, but close attention must be paid to maintaining signal integrity
in design and implementation of the connections.

Eagle systems require calibration on an annual basis to
maintain performance within factory specifications. The LeCroy
maintenance agreements normally include annual calibration of the
system.

Connecting to the PeRT
Overview of Connection
The PeRT3 Eagle System allows the user to be directly connected to the PeRT3 system
in use, or connected remotely via a network. This latter method is very useful when the
system is located in a lab or other remote location, and the user wishes to conduct testing
from their office (or home).
To support this flexibility, the software application includes both a client, which contains
the user interface displayed to the user, and a server, which communicates directly with
the PeRT
hardware, the client may exist on any PC that has a network connection to the server.
By default, the PeRT

results) is that while running (but not recording results) the system
allows the user to change any of the signal or jitter settings while a
test is running. This is useful during initial test development to
quickly determine how the device under test behaves under different
conditions. If results are being recorded, the user may not change
test settings without first stopping the test.
Once the test is selected, the test can be started by clicking the Start (record results)
button in the Master Controls panel.
Once the test is running, the Pause and Stop buttons will become active, and can be
used to pause or stop the test respectively. The indicators to the immediate right of these
buttons (marked "1", "2", "3", and "4") refer to the four channels which can be tested
simultaneously. If a channel is active, the indicator corresponding to that channel will be
lit. In addition, a summary of error results is provided for each channel in the status
screen in the center of the Master Controls panel.

Chapter 3: Basic Principles of Operation
The PeRT3 Eagle generates a serial bit stream for testing of receivers through a
two-stage process. In the first stage, the bit stream is developed in accordance with the
protocol being used (if selected) and the test patterns selected. This bit stream is
originally generated to be as clean and precise as possible.
In the second step, the clean bit stream generated in the first step is passed through a
series of stages which introduce controlled distortions into the signal. There are many
choices for type of distortion, each type has many possible levels, and multiple types of
distortion can be overlapped to produce complex, but controllable, irregularities in the
signal generated. The system is designed to allow the user to test signal distortions along
many different axes (types and combinations of signal degradation), and allows the user
to establish either a simple PASS/FAIL test at a given level of distortion, or to explore the
performance envelope of a receiver by multiple tests, each of which introduces
increasing levels of distortion along different axes until predefined bit error levels are
exceeded.
In the process of testing a receiver, the device containing the receiver is first connected
to the system, then the device may go through an initialization phase, after which the
device is placed into a test mode (e.g., a simple loopback mode) which returns the signal
to the PeRT

Introduction of Stress into Waveform
The analog front end introduces stress (or distortion) into the waveform as desired by the
user. The stressed waveform can be used to explore the performance envelope of the
device under test, to determine the types and amounts of stress the device or design can
tolerate before desired bit error rates are exceeded.
Examples of the eye diagrams that result from introduction of certain types of stress are
shown below.

Main Application Window
The main application window has two major sections, organized horizontally from top to
bottom as follows:
• The System Control Ribbon, located at the top of the window.
• The Test Development section, located in the bottom of the window .
There are two windows that by default occupy space within the Test Development
section. These are the Main Library window and the Output window. By default these
windows are "docked" to the left and bottom of the main application window, and any Test
Scripts, Test Patterns or Test Results windows displayed in the Test Development
portion will be sized to fit the remaining space.
Information on re-positioning these windows can be found in “Customizing the Main
Library and Output Windows” on page 66.
The positions and relative sizes for these sections as shown above are the default sizes
and locations. The user has significant control over the locations and sizes of the various
windows. Windows can be turned on and off to suit the user’s needs. See Chapter 10:
Control of Screen Appearance.

Main Library Window
The Main Library window provides information on
the status of a test script through the box located just
left of the script name. An open box indicates that
the script is stored on the server. A solid green
square indicates that a copy of this script has been
retrieved from the server and is currently on the client
PC as well. A solid green square with an asterisk
indicates that the script has been modified but not yet
saved on the server. A solid green square with an
arrow indicates a test script which is currently

Chapter 5: Manual Testing
The PeRT3 Eagle supports the ability to conduct quick manual tests in addition to running
preprogrammed test scripts supplied with the system or developed by the user.
Manual testing is controlled by the System Control Ribbon located at the top of the PeRT
main application window. Manual testing is a good introduction to how to develop test
scripts, since the steps followed are largely the same.
To set up a test, work from left to right across the panels in the Main tab, starting with the
3
PeRT
panel to select the system to be used, then the Configuration panel to select the
protocol and data rate, followed by the DUT Initialization panel to specify the DUT setup
and initialization sequences, and finally to the DUT Status panel to connect to the DUT.
System Control Ribbon - Main Tab
If the Main tab along the top of the System Control Ribbon is clicked, the ribbon will show
a series of five panels, as follows:
Master Controls
The Master Controls panel allows the user to
specify the test to be run. If a manual test is
desired, select Manual Test in the drop-down
menu (this is the first item on the list). This
allows the user to Start (don’t record), Start
(record results), Pause or Suspend the test,
to Connect or Disconnect from the DUT, and
indicates which channels are being tested
through the "1", "2", "3" and "4" which function
as on-screen LEDs to show which channels are
active. Also, the panel shows the status of bit
errors encountered on each of the channels while the test is running and allows the user
to deliberately inject a bit error (into all active channels) by clicking the button on the lower
right.
3
Note: The difference between Start (don’t record) and Start (record
results) is that while running (but not recording results) the system
allows the user to change any of the signal or jitter settings while a
test is running. This is useful during initial test development to
quickly determine how the device under test behaves under different
conditions. If results are being recorded, the user may not change
test settings without first stopping the test.
LeCroy Corporation 23
Version 1.6 PeRT3 Eagle User Manual
PeRT3 Selection
The PeRT3 Selection panel allows the user to
specify which PeRT
this application by selecting either the local PC or a
remote PC. When the host PC is selected from the
drop-down menu, information about the Eagle R6
and Eagle FE6 associated with that system is shown
in the fields below the system name. In addition, this
allows the user to specify the number of channels to
be tested (up to the maximum number supported by
the hardware configuration).
3
system is to be controlled by
Configuration
The Configuration panel allows the user to specify the
the protocol to be used during testing, the data rate to
be used for the test, whether spread spectrum clocking
(SSC) is to be used, and the signal to be applied to the
"Clock Out" port located on the front panel.
Allowed values for these fields are:
Protocol: SATA, SAS, PCI Express, USB 3.0,
Custom or Generator Only. Choose
SATA, SAS, PCI Express or USB 3.0 to
test devices which use those protocols. Custom may be used for custom
protocols that include such things as user-defined DUT initialization
sequences and user-defined patterns specific to the user’s protocol, or for
cables, backplanes and other passive components. The Generator Only
option is provided to support situations where the user wishes to use the
3
PeRT
system as a signal generator but is not returning any signal to the
system. In this case, the system will generate a test signal without
"connecting" to any device and will not monitor the return channel.
Note: Changing the protocol selection may require loading new
firmware. If so, this may take a few minutes.
Speed: The PeRT
3
Eagle supports multiple data rates (1.5, 2.5, 3, 5 and 6 Gb/sec)
and the selections displayed will depend on the protocol selected (for
example, for SAS and SATA, 1.5, 3 and 6 Gb/sec options are displayed; for
PCI Express, 2.5 and 5 Gb/sec options are displayed).
SSC: Controls whether spread spectrum clocking (SSC) is used for clocking the
outgoing serial stream.
Clock Out: This controls the Clock Out connection on the front panel of the PeRT
3
Eagle.
The user can select At Rate, 100 MHz, 125 MHz, 10 MHz or Other. At Rate
will use the data rate of the system. Other allows the user to specify an
arbitrary clock out rate. If a rate is selected which is not an integral division
of the base rate, the rate will be adjusted to the nearest rate than can be
achieved using the clock divider hardware. The Clock Out signal can be
controlled further (to introduce delay or jitter) through the Clock Out under the
Options tab.
24 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
Changing any of these parameters does not change the system configuration until the
Apply button is clicked. The two buttons (Apply and Cancel) allow the user to set a
complete configuration before applying it to the system.
DUT Initialization
The DUT Initialization panel allows the user to define
how the test device is to be initialized to place the device
in a loopback mode. Direction has three options, and
defines whether the Device under Test (DUT) is logically
a device/target (DUT is Device), a host (DUT is Host) or
is Undefined. If "Undefined" is selected, the system will
be unable to automatically initialize the device under test
and the device will need to be initialized by the user prior
to running tests.
The Initialize menu provides the ability to select a standard, protocol-specific
initialization sequence (such as a pre-defined command to place the DUT into a loopback
mode), or to use a custom sequence that has been define by the user. If a custom
sequence is used, the Sequence menu allows the user to select a specific sequence
from the list of pre-defined test patterns. For example, if the device manufacturer
supports a vendor-specific pattern to initiate a loopback test mode, the user can define
that Vendor Specific Pattern (using the Pattern Editor — see later section) and select that
pattern from the drop-down menu provided.
The Count menu allows the user to choose between counting errors at the bit level (such
as is done for standard BER testing), or to count errors at the frame level (so that multiple
bit errors occurring within the same frame are counted as a single error).
DUT Status
The DUT Status panel show the status of the DUT, including
whether the loopback mode is currently active. The user can issue
manual commands to Connect, Reset or Disconnect from the
device by clicking the appropriate button on this panel.
System Control Ribbon -- Channel Tabs
The System Control Ribbon has up to four tabs which correspond to single channels in a
four-channel system, labeled Channel 1, Channel 2, Channel 3 and Channel 4. The
numbers of channel tabs that appear will correspond to the number of channels that were
licensed at purchase. If more than one channel was licensed, there will also be a
Channel Master tab. Changes to settings made in the Channel Master tab are applied
to all available channels, whereas changes made in any individual channel tab are
applied only to that specific channel. This allows the user to adjust the test conditions for
each channel independently.
LeCroy Corporation 25
Version 1.6 PeRT3 Eagle User Manual
If the Channel Master tab or any specific channel tab along the top of the System Control
Ribbon is clicked, the appropriate Channel controls will appear. The Channel tab
contains up to 10 panels, which are used primarily to control the different types of signal
degradation which can be introduced into the test signal, and to define (if desired) the
ending conditions for the test. The Channel tab appears as follows (for the examples to
follow, we will use the Channel Master tab, and the individual Channel tabs are identical
in operation):
Once the device has been configured, the user is likely to to use the Channel tab(s) in
the Manual Test mode to control and modify the test conditions while developing an
appropriate test for the device. These tabs allow immediate access to all forms of signal
stress that can be introduced and allows the user to quickly experiment with different
forms and levels of stress to roughly determine the performance envelope for the device.
Panels that can be accessed from the Channel tabs include the following:
Signal Generation and Introduction of Distortion
Master Controls
The Master Controls panel is a duplicate of the
panel which also appears in the Main control
strip (see section above), and allows the user
to Start (don’t record), Start (record results),
Pause and Suspend the test, while providing
information on bit errors encountered and
channels that are active.
The PeRT3 Eagle System initially generates a high-quality, low-jitter signal for testing.
This signal can be modified by introducing increasing levels of different types of distortion
to determine the performance of a transceiver system under stressed conditions. For
more discussion of the effects of each type of stress on the signal produced, see Chapter
3, Basic Principles of Operation.
Overview of Signal Impairment Controls
The signal impairment controls provide extensive capabilities for the user to modify the
outgoing serial data signal so as to fully explore the performance envelope of the device
under test (DUT). Each control offers sophisticated ability to control a specific variable,
and can be used alone or in combination with other variables to produce complex but
controlled test scenarios.
26 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
The signal controls appear deceptively simple but allow quick access
to complex test sequences. Each control has a slider bar that can be
used to change the nominal value, with the selected value appearing
below the bar. The "+" and "-" buttons can be used for fine tuning the
value, or the user can click on the displayed value (such as the "400"
displayed to the left in the Amplitude control) and type in a specific
value. Typically each control has a range of allowed values, and if the
value typed in is not supported, the closest available value will be
substituted.
An automatic range of values can be very easily defined by moving the
slider to the starting value of the range, and then holding down the
"Shift" key while dragging the slider to the end value for the range
(either from low to high or from high to low). This creates a sequence
of values from the starting value to the ending value, with a total of 10
(roughly) equal steps in the range. The range is displayed as shown at
the left (in this example, using 200 as the starting value and 1100 as
the ending value).
For more exact control of test ranges, to the immediate right
of each control heading is a small arrow that provides
access to automatic ranges for each control. By clicking this
arrow, the screen displayed on the left appears. This screen
allows the user to enable automated testing of a
well-defined range of values, to define the minimum and
maximum values of the range, to define whether the range
is to be executed from minimum value to maximum value or
vice versa, to define the number of steps within the range,
or to define custom (unequal or non-sequential) steps for the
range. To define a range, click the Enable Range box, set
the minimum and maximum values, set the number of steps,
and click or unclick the Low to High box (if unclicked, the
range will run high to low).
Once a range has been defined, click outside the range box and the
slider bar will now display the defined range as shown on the left. The
minimum and maximum values are indicated and the direction of
change is shown by the arrow.
LeCroy Corporation 27
Version 1.6 PeRT3 Eagle User Manual
If custom steps are desired, click the Custom Steps box and type in the
values desired, in any sequence desired, separated by commas. For
example, you can type "100, 200, 500, 1000, 2000" which produces the
display as shown on the left. You can also type in non-sequential
values, such as "100, 1000, 200, 2000, 500" and the steps will be
executed as entered.
To delete a range, click on the small arrow to the right of the heading,
and unclick the Enable Range box, or simply change the setting by
moving the slider or clicking the + or - button and the range will be
removed.
An aid to entering and changing values for signal impairment controls can be found by
turning on the On-screen Keypad. The On-screen Keypad can be turned on from the
View panel of the Options tab. When turned on, if the numeric value below the slider
bar in any control is clicked, the value will be highlighted and the On-screen Keypad will
appear as shown below.

PeRT3 Eagle User Manual Version 1.6
Signal
The Signal panel allows the user to control the amplitude and bias of the
differential signal. By default, the Signal panel is inactive (turned off)
when the system is first turned on, as shown by the circle in the lower
right corner of the panel. Before any testing can take place, the user
must turn this on (click to change to a check mark) and specify the
desired signal characteristics.
Signal amplitude (Amp) can be controlled over the range from 100 mV
to 2200 mV in increments of 5 mV. Signal amplitude is the nominal
voltage of the differential signal, and is a measure of the overall signal
power. Low signal amplitude can be used to test for the limits of receiver
sensitivity (additional losses due to connectors and cables should be taken into account).
High signal amplitudes can be used to test for receiver saturation or even damage limits
to electronics.
Signal bias can be controlled over the range -1800 mV to +1800 mV in increments of 5
mV. Signal bias is the offset (from ground) that is applied to the differential signal, or in
other words, the DC component of the signal.
Note: All signal impairment controls are turned off by default. All controls
must first be turned on by clicking the circle in the bottom right corner
of each panel. When the control is active, the circle will change to a
check mark
Pre-Emphasis
The Pre-Emphasis panel allows the user to control the amplitude and
duration of the pre-emphasis applied to the signal. By default,
Pre-Emphasis is turned off.
Pre-emphasis amplitude (Amp) can be controlled over the range 0 to
15 (nominal values). Pre-emphasis amplitude is used to adjust the
amplitude of the overshoot and undershoot on transitions, and can be
manually adjusted (while examining the signal on an oscilloscope) to
obtain a desired waveform. Pre-emphasis is not usually needed if the
SMA cables connecting to the DUT are short and trace lengths on any
test fixtures used are minimal.
Pre-emphasis duration ("Dur") can be controlled over the range from 0 to 15 (again,
nominal values). Pre-emphasis duration is used in combination with pre-emphasis
amplitude to control the overshoot on electrical transitions in the bit stream.
LeCroy Corporation 29
Version 1.6 PeRT3 Eagle User Manual
Random Jitter
The Random Jitter panel allows the user to introduce and control
random jitter into the signal.
Random jitter can be low frequency (LF), high frequency (HF) or a
combination of the two. Random jitter (either LF or HF) can be
controlled over the range from a minimum available value
(established by calibration of the system) to 12 ps in increments of
0.1 ps. The value selected is the root-mean-square (RMS) of the
jitter introduced.
When used in this context, jitter is the variation in pulse position in
the time domain. In an ideal jitter-free system, each electrical transition would occur at
precise intervals defined by the data rate of the bit stream (e.g., 6 Gb/sec). In practice,
there is always some level of jitter as subsequent pulse edges vary slightly from the ideal,
and as this variation becomes appreciable relative to the length of each pulse, the
receiver has more challenge to correctly determine the value of the bit.
Since random jitter is specified in picoseconds (ps), the degree to which the bit stream is
degraded through the introduction of random jitter will also depend on the data rate. For
a data rate of 1.5 Gb/sec, the width of each bit is 667 ps, so an RMS jitter of 6 ps would
introduce an average variation of approximately 1% of the pulse width (or unit interval).
For a data rate of 6 Gb/sec, the pulse width is 167 ps, and the same 6 ps RMS jitter is an
average variation of approximately 4% of the pulse width (or unit interval).
The random jitter is generated by a physical noise source with a roughly Gaussian
distribution, so while the RMS of the random jitter to 4% of the unit interval, a small
number of transitions will have considerably larger jitter. On average one in a trillion
12
(10
) transitions will have 14 times as much jitter (or 56% of the unit interval in the case
of 4% RMS).
The Low Frequency Random Jitter is generated by passing the random source through
a low pass filter as called for in the PCIe compliance specification. The resulting jitter is
bandwidth limited and will not necessarily be measured as "random" jitter on many
scopes or other jitter measurement tools and packages that define random jitter as jitter
with a flat frequency spectrum and use frequency analysis to separate random jitter from
deterministic jitter. The High Frequency Random Jitter source, on the other hand, is not
frequency limited and will appear as random jitter when measured by such instruments.
30 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
High Frequency Sinusoidal Jitter
The High Frequency Sinusoidal Jitter panel ("High Freq SJ") allows
the introduction of periodic jitter at controlled frequencies and
amplitudes.
High frequency SJ can be controlled over an amplitude range of 0 to
290 ps in increments of 1 ps.
High frequency SJ can be controlled over a frequency range of 1.0 to
115 MHz in increments of 0.1 MHz.
Low Frequency Sinusoidal Jitter
Low Frequency SJ is analogous to high frequency SJ, and can be
controlled over amplitudes of 400 to 10,000 ps in increments of 50 ps.
The frequency can be controlled from 250 to 2,000 KHz in increments
of 1 KHz.
High frequency SJ and low frequency SJ can be used in any
combination (and also with random jitter) to produce complex yet
reproducible jitter scenarios for testing of serial data devices.
The frequency range of Low Frequency Sinusoidal Jitter is typically
below the frequency that is tracked out by standard PLLs. This means
that typical devices can tolerate Low Frequency Sinusoidal Jitter in excess of several unit
intervals. It also means that measurement and calibration of sinusoidal jitter at low
frequencies require techniques that take into account the effects of any PLL used to
recover the data.
Pattern/Termination
The Pattern/Termination panel allows the user to
define the test pattern to be used during the test,
and to define the termination conditions for ending
the test.
The Pattern is selected from the drop-down menu,
and can be any pattern that is supplied with the
system or has been created by the user using the
Pattern Editor (see later section).
The Terminate after field allows the user to select
the conditions that will terminate the test. There are fields below the Terminate after field
which change depending on the selection made in the Terminate after field. You can
choose from the following options:
Run Forever If Run Forever is selected, the test will continue until the user stops
the test using the Suspend or Stop buttons in the Master Controls .
Max Bit Count If Max Bit Count is selected, the test will continue until the number of
Gbits of data specified in the Max GBits field has been exceeded.
Under nominal conditions, this is equilavent to a fixed time period (that
will depend on the data rate selected or negotiated by the system). In
the marginal test case where the device under test sporadically loses
and regains signal lock, it may take longer to achieve the expected bit
LeCroy Corporation 31
Version 1.6 PeRT3 Eagle User Manual
count than the equivalent time period. In the event the device totally
loses signal lock and stops transmitting, the test case will eventually
time out even if the maximum bit count is never achieved.
Elapsed Time If Elapsed Time is selected, the test will continue for the time
specified, then terminate.
PASS/FAIL If PASS/FAIL Confidence is
Confidence selected, the test will continue
until the numbers of errors
encountered combined with the
number of bits processed
exceeds a specified confidence
level that the receiver is
passing or is failing the test.
The criterion required
(maximum error ratio) is
specified in the Pass/Fail BER
(bit error ratio) field, and the desired confidence level is specified in the
%Confidence field. Note that when this selection is made, the actual
length in time of the test may vary significantly from test to test, since
the actual number of errors encountered will affect the number of bits
which need to be processed to obtain the desired confidence level that
the specification has been met (or has been failed).
Time or If Time or Max Errors is selected, the test will continue until either the
Max Errors time specified is reached or
exceeded, whichever occurs first.
Time or If Time or PASS/FAIL is selected, the test will continue until either the
PASS/FAIL time specified is reached or
specified confidence level, whichever occurs first.
the maximum numbers of errors is
the Pass/Fail BER is achieved with the
Find BER Curve If Find BER Curve is selected,
the system will performed an
automated jitter tolerance test
using a single variable (e.g., HF
SJ Amplitude). You can specify
the PASS/FAIL BER to be
used, and the parameter to be
scanned. The system will then
automatically scan through the
settings of the specified jitter
parameter to identify the
maximum setting that the DUT can tolerate without exceeding the
BER threshold specified.
Other Channel If Other Channel is selected, the test will run on the specified channel
until the tests on the other channels that are currently running
terminate. Typically you would select this option when doing
"victim/aggressor" testing and you want to send a specific pattern on
the "aggressor" channels while testing the effects of cross-talk on the
32 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
"victim" channel. At least one active channel should have a specific
termination criteria. Setting all channels to terminate on Other
Channel would be the equivalent of specifying Run Forever.
Note: The test termination conditions can be channel-specific. If
different termination conditions are selected on different
channels, the test will continue to run until all termination
conditions on all channels have been met.
Eye Preview
The Eye Preview panel provides a calculated simulation of the
expected jitter eye diagram as it would be displayed on an
oscilloscope. The eye preview is useful for quickly determining
the approximate level of signal impairment based on the current
system settings.
Note the simulated Eye Preview does not include the affects of
common mode interference or low frequency SJ because this
affect is typically cancelled out by a differential probe and a
scope PLL and does not generally show up on most scope eye
diagrams. Also, including this affect in the calculated eye
diagram is generally not useful as it often results in a completely closed eye.

Default Settings
The Default Settings panel allows the user to
establish the default values that appear whenever a
protocol, number of channels, or Host/Device setting
is required. Establishing these default values saves
the user time in not needing to change values
constantly when working on a particular development
project.
The Auto display graph option, if selected, will result
in a new graph being displayed and updated in real
time whenever you run a test that records results.
LeCroy Corporation 33
Version 1.6 PeRT3 Eagle User Manual
Pattern Checking
The PeRT3 system normally validates patterns to ensure they
conform with the specification requirements for the type of testing
taking place.
As an example, if testing Frame Error Rate of a SATA device, the
pattern must be a valid SATA Frame without any encoding errors
and with a correct CRC. If the selected pattern is not a valid SATA
frame, pattern checking will detect this and issue a warning and
substitute a default pattern that is valid for the specified test
mode.
The Pattern Checking panel allows the user to control what types of pattern checking take
place, and in rare instances, to turn off the automatic pattern checking for specific tests.
Consider a case in which the user wanted to deliberately send an invalid frame to test the
DUT's higher level protocol handling logic. Deliberately sending an invalid frame should
result in a 100% frame error rate as the DUT should reject every instance of the frame
that is sent. Similarly during SATA bit error ratio testing, the pattern must contain ALIGNs
at the proper intervals for the device to work. By default the PeRT
correct interval. But the user may want to disable this feature if the device under test was
not working with the standard ALIGN frequency. In such a case the user might still want
to test the device by creating their own custom pattern that had more (or less) frequent
ALIGNs in them. In that case the SATA align verification could be turned off, and the
3
PeRT
would send the pattern exactly as the user specifies it without inserting additional
ALIGNs in the pattern specified (the PeRT
3
would still ignore ALIGNs inserted or
removed by the DUT for purposes of BER calculation.)
If doing simple BER testing in Custom mode, no pattern validation will take place,
because there are no requirements placed on a pattern in Custom mode. There is no
need to turn off pattern validation in this case.

inserts these at the
External Options
The External Options panel allows the user to specify the use of
an external switching board and/or an external reference clock.
The External OOB Board is a connection board that provides
rapid OOB signal switching under the control of the PeRT
hardware. The OOB Board connects via the 25-pin auxillary
connector on the lower right of the PeRT
3
Eagle front panel.
For most applications and devices, the internal PeRT
is able to perform OOB signaling. However, some SATA hosts are
not compliant with the SATA specification, and for those specific
hosts the external OOB board is required in order to use the PeRT
devices. It is not required for SATA devices, or if testers have external means of putting
the SATA host into loopback mode, or if the SATA host adheres to the SATA specifications
for loopback.
The External OOB Board is automatically detected if it is present at start-up. If it is
automatically detected, the box will be checked but the control will be disabled (i.e. you
won't be able to uncheck the box). You must power down the hardware when connecting
or disconnecting the External OOB Board. After powering the hardware back up you will
need to reconnect the application to the hardware and the External board setting should
be automatically set.

If no board is detected (either because none is present or because in some older systems
the hardware doesn't support automatic detection) then the Ext OOB Board box will not
be checked, but the user will be allowed to check or uncheck it to indicate the presence
or absence of the board. If the board is connected it is vital that this box be checked,
otherwise signal amplitude and OOB signaling will not function properly.
The Ref Clk in allows the user to provide an external clock for the system and specify
the nominal frequency of this clock signal, which is supplied via the Reference Clock In
connector on the back panel of the system.
External Jitter
The External Jitter panel is used in combination with
the Jitter In connector on the front panel of the PeRT
Eagle system. This allows the user to introduce
other sources of jitter, and to control how those
additional jitter sources are applied to each channel.
The Main control acts as a master amplitude control
in applying the external jitter across all channels.
The individual channel controls allow the user to
selectively apply the external jitter to specific
channels.

Clock Out
The Clock Out panel controls the Clock Out signal which can be used to
control external equipment. These controls allow the user to introduce a
delay of 0 to 100 ps, and to introduce a jitter of 0 to 6 ps into the clock
signal.
Diagnostics
The Diagnostics panel allows the user to test the operation of system
components, including the digital electronics ("Eagle R-6"), the analog
front end ("Eagle FE-6"), and correct connectivity between the two
sections. The results of the diagnostics tests are displayed in the
Output window.

Note that if the Main Library window is too narrow to
display all available buttons, a small double arrow will
appear on the right side of the list of buttons. Clicking
this double arrow will provide a drop-down list of the
remaining buttons, as shown on the right.
By selecting the appropriate tab (Test Scripts or Tes t
Patterns) and then clicking the Create a New Item
icon, new test scripts and test patterns can be
generated as described in the following chapters.
By double-clicking on the name of a test script or test
pattern, the user can view the script or pattern details
and can modify the script or pattern. By
double-clicking on a test result, the user can display
test results in the analysis window as a graph or table (see Chapter 9: Analysis and
Reports). Test results can not be modified.
The Filter Function
The Filter button can be used to control what is displayed in the various tabs (Test
Scripts, Test Patterns, Test Results) of the Main Library window.
For Test Scripts, the user can select either No Filter or
Protocol Specific filter. Selecting Protocol Specific
limits the items displayed in the Test Scripts section to
scripts written for the current protocol. (The current
protocol is the protocol selected in the Configuration
panel of the Main tab.)
For Test Patterns, the user can select No Filter, Protocol
Specific, or Allowable Patterns. If Protocol Specific is
selected, patterns that have been written for the selected
protocol are displayed. If Allowable Patterns is selected,
patterns that are permitted under the current protocol are
displayed. This may include some generic patterns but will
exclude patterns that were written for the current protocol
but are not valid under that protocol.
For Test Results, the user can select No Filter, Today, Last
Week, or Arbitrary Date. If To day is selected, only test
results obtained in the last 24 hours are displayed. If Last
Week is selected, only test results obtained in the last seven
days are displayed. If Arbitrary Date is selected, a window
will appear to allow the user to select a range of dates.

Chapter 7: Creating a New Test Script
A new test script can be created by first clicking on the Tes t S c r ipts tab in the Main
Library window, then clicking the icon ("Create a New Item").
Clicking this icon enters a new item in the list of test scripts (named by default "New Test
Suite"), and opens a window in the Test Development portion of the PeRT
application window. This window fills the available area of the PeRT
window below the System Control Ribbon.
Note: By default, the Main Library window and the Output window are
"docked" to the side and bottom of the main application window, and
the new Test Script window fills the remaining space. If either the
Main Library or the Output windows are undocked and left floating,
the new Test Script window will expand to fill that space, and portions
of the Test Script window may be obscured by the floating
window(s).

(see the icon circled in red at the right). This will minimize the two windows (the Main
Library window will flatten to the left side of the main application window, and the Output
window will flatten to the bottom of the main application window).
The resulting main application window display will appears as shown below, allowing
more space for test script and pattern editing:
The minimized windows can be temporarily viewed by hovering the cursor over the green
button next to the window name, and the window will disappear again when the cursor is
moved off the window. To restore the window to normal size, hover the mouse over the
green button to make the window appear, and then click the pin icon again.
Starting a New Test Script
Start a new test script by hovering the mouse over the green button of the Main Library
window until it appears, make sure the Test S c ripts tab is selected, and clicking the New
icon at the top of the window.
40 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
These actions produce a main application window which looks as follows, providing more
visible space for test script development:
Test Script Data Block
The first block that appears in the new test script window is the header block, named Tes t
Script Data. This block contains the Script Data tab, which contains three panels, Basic
Data, Test Description and Device Description.
Basic Data
The Basic Data panel allows the user to name the
test script and identify the creator of the script by
entering this information into the Script Name and
Creator fields. The Script Name will be the name
listed in the Main Library window, under the Test
Scripts tab, whenever that window is displayed.
LeCroy Corporation 41
Version 1.6 PeRT3 Eagle User Manual
Test Description
The Tes t D e scription panel allows the user to
designated the Test Type (either Receiver Test or
Transmitter Test) and number of channels to be
tested (from 1 to the maximum number supported by
the system hardware). The channels tested will always
start with Channel 1 (e.g., if two channels are selected on a system that supports four
channels, the channels tested will be Channel 1 and Channel 2).
Device Description
The Device Description panel allows the user to specify
the protocol to be used (options are SATA, SAS, PCIe,
USB 3.0, Custom or None) and the direction (DUT is
Device or DUT is Host).
Building a Test Script Block-by-Block
Test scripts are built block-by-block through the
addition of new blocks. At the bottom of the test
script will appear the options to add a
Reset/Initialize block or to add a Test Case block.
The Reset/Initialize block is normally the first block added immediately after the Test
Script Data Panel, since typically a device first needs to be initialized and placed into the
loopback mode prior to any Test Case. However, the Reset/Initialize block can also be
used at later times during a test script, if the user desires to reset the device prior to the
next Test Case or to terminate the testing with a final reset to place the device into a
known condition.
The Reset/Initialize block may be omitted entirely if the device is going to be manually
placed into a loopback mode prior to running the test script.
Reset/ Initialize Block
The Reset/Initialize Block contains the Device Reset tab, which contains three panels,
Setup, Initialization and Automation.
Setup
The Setup panel allows the user to specify (or change)
the data rate, the use of SSC and the Clock Out
settings. Depending on the protocol selected, the
options will include all supported data rates.
42 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
Initialization
The Initialization panel allows the user to select an
initialization command sequence. The options displayed
here are dependent on the protocol selected, but
typically include Loopback, Frame Level, Custom or
None. Loopback will place the DUT into a loopback
mode for testing. If no standard "enter loopback test mode" command exists in that
protocol, but the device vendor supports a custom command, that command can be
entered using the Pattern Editor (see “Creating Test Patterns” on page 45) and then
selected from the drop-down menu of existing patterns in the Sequence field of this
panel. This also allows the testing to change between bit level errors and frame level
errors by selecting the desired method from the Count drop-down menu.
Automation
The Automation panel allows the user to specify reset
conditions that might be required during automated testing.
Reset on each test case will force a reset each time a new
test case begins, and Auto reset on lost lock will reset the
system and attempt to recover lock when lost.
Receiver Test Case Block
The Receiver Test block contains tabs across the top corresponding to channels
supported by the system. The Channel Master tab controls all channels (if using a single
channel system, there will be no Channel Master tab, only the Channel 1 tab will be
shown). Click on a specific channel tab to select any of the channels to be tested (limited
by the number of channels defined in the Test Script Data Panel). Selecting any of
these tabs allows the user to specify the test conditions for that specific channel.
Test conditions for channels are defined in exactly the same way as previously outlined
under Manual Testing, see “System Control Ribbon -- Channel Tabs” on page 25.
A single Receiver Test block can be used to test all channels simultaneously by
specifying the same (or different) test conditions for each channel, or each channel may
be tested in sequence by adding additional Receiver Test blocks and defining a test for
only one channel in each Receiver Test block.
When defining test conditions, the Eye Diagram panel serves as a guide to the level of
signal impairment being introduced by the conditions specified in this specific test case.
LeCroy Corporation 43
Version 1.6 PeRT3 Eagle User Manual
Adding, Inserting and Deleting Test Cases
Test Scripts are built block-by-block in this fashion
by adding new test cases to the end of the script
using the Reset/Initialize or Test C a s e buttons at
the bottom of the script.
New test cases can be inserted at any point in the test script
by using the "Insert Above" button which is located in the
top left of each block . When this button is clicked, the menu
shown on the right appears to allow you to insert either a
Reset/Initialize block or a Receiver test case block. By
default, the new test case is a copy of the existing test case.
Blocks can be deleted from the script by using the "Delete" button , also in the top right
corner of each block.

PeRT3 Eagle User Manual Version 1.6
Chapter 8: Creating Test Patterns
The PeRT3 Eagle System includes a library of predefined test patterns, that for many
users may fully satisfy their requirements.
Some users may wish to create additional test patterns or to modify the patterns supplied
with the system. A simple example of the need to create a test pattern is when the user’s
device has a vendor-specific command which is required to place the device into a test
loopback mode. In this case, the vendor-specific command can be created using the
Pattern Editor and then selected in the DUT Initialization panel of the Main tab in the
System Control Ribbon (see “DUT Initialization” on page 25).
Creating a New Test Pattern
A new test pattern can be created by clicking
on the Test Patterns tab in the Main Library
window, then clicking the Create New Item
icon in the task bar.
When a new test pattern is created, it has
certain default characteristics which are
determined by the Default Settings which
are currently set for the system. (To change
the Default Settings, click the Options tab
on the System Control Ribbon and select the
desired values in the Default Settings
panel.)
If the default settings are not desired, they
can easily be changed by, for example,
selecting a different protocol in the Decode
As field of the Display Mode panel of the
Pattern tab.
It is important to have the Decode As field
set to the correct protocol for the pattern you
are defining. Not only does this dictate how
the pattern is displayed in the pattern editor,
it also controls how it is sorted and displayed
in the pattern picker.
When the Create New Item icon is clicked,
a Pattern Editor window appears within the PeRT
System Control Ribbon. The Pattern Editor window has two sections: the upper section
displays the actual data pattern being created, and the lower section displays the current
data decoded as a protocol primitive or frame using the protocol selected in the Decode
As field.
To create a new pattern click on the Pattern tab in the System Control Ribbon. The
display, showing the Pattern Editor window and the Pattern tab controls, is shown
below:
LeCroy Corporation 45

main application window below the
Version 1.6 PeRT3 Eagle User Manual
The default name for the new pattern is "New Pattern". This name can be changed by
selecting the new pattern in the Main Library (it will be at the bottom of the list) and
clicking on the Rename the Selected Item icon in the Main Library window toolbar.
Pattern Editor Tab Controls
The Pattern tab contains seven panels, which allow the user to create new patterns and
edit existing patterns. These panels are Master, Display Mode, Standard Edit, Pattern
Edit, Import/Export, View Info and Notifications. Each of these panels is described
below.
Master
The Master panel provides controls to start and stop a test, and to connect
and disconnect to the DUT. The four numbered indicators light to show
which channel(s) are being tested.
Display Mode
The Display Mode panel allows the user to specify
the protocol to be used when decoding frames, the
width of the data display, the direction for data
display, and the format for the pattern data. There
are six different formats that can be used for
displaying the pattern data. From left to right in the
selection bar, these formats are:
46 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
• Display as a wave form
• Display the binary pattern as 1’s and 0’s
• Display the pattern in 10bit data format
• Display the pattern in K/D symbols (default selection)
• Display the pattern in scrambled data format
• Display the pattern in unscrambled data format
LeCroy Corporation 47
Version 1.6 PeRT3 Eagle User Manual
Standard Edit
The Standard Edit panel provides a set of editing tools similar
to those found in many applications for simple editing tasks.
The tools provided include:
• Undo
• Redo
• Copy
• Paste
• Cut
Pattern Edit
The Pattern Edit panel provides the key controls for creating
and editing data patterns. These controls include the following:
• Insert Frame (the frame will be structured
according to the selected protocol)
• Delete Frame
• Insert Data
• Delete Data
• Adjust RD+ (adjusts channel symbols to start
with positive dispersity)
• Adjust RD- (adjusts channel symbols to start with negative dispersity)
Import/Export
The Import/Export panel allows the user to import data that becomes
part of the pattern being edited, or to export data that is part of the pattern.
View Info
The View Info panel is a status display to help the user
navigate through a data pattern. The displays the current
location within the pattern in terms of the frame number, the
number of bytes into the stream, and the number of bytes into
the frame.
48 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
Notifications
The Notifications panel allows the user to request notification when an
invalid 10b data pattern is part of the current pattern. This is a form of
automatic error checking when the user is entering encoded data at the
10b level.
Once there is some initial data in the pattern, some of these commands can also be
accessed by right-clicking the mouse while hovering over a data cell in the data pattern.
Adding Frames to Patterns
Frames can be added to the pattern by clicking the Insert Frame icon. When this
icon is clicked, a library of available frames that are pre-defined for the selected protocol
appears:
LeCroy Corporation 49
Version 1.6 PeRT3 Eagle User Manual
By clicking on any frame and then clicking Insert Frame, the frame is entered into the
pattern:
The top section of the window shows the actual data (each symbol displayed using the
selected display format). The bottom section of the window shows the definition of the
frame format. This allows the user to modify the frame by directly entering information
into fields of the frame in the bottom section, using either pull-down menus (provided
where appropriate) or directly typing in the desired value where appropriate.
When the information in a frame is changed, the
CRC which has been calculated is no longer
correct. This condition is indicated by the background color changing to red. If desired,
the CRC can be recalculated to the correct value by right-clicking on the CRC value and
selecting the Update with the valid value command which appears. The actual data
which is changed is highlighted for a short time in the upper portion of the window.
Additional primitives and frames can be added to create a more complex series of
commands, all of which are reduced to the appropriate bit pattern which is displayed in
the upper portion of the window.
Adding Data to Patterns
Data can be added to a pattern by clicking the Insert Data icon in the Pattern Edit or
by using the Import Data command in the Import/Export panel.
50 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
Clicking the Insert Data icon brings up the following window:
This window allows the user to enter a repeated value into the data, with the choice of
entering the data either before or after any symbol shown in the data stream.
Clicking the Import Data icon brings up the following window:
By clicking on the "..." button, the user can navigate the file system to locate the data file
to be imported, and then click the Import button to import the data.
Note that if data is entered outside of a frame, the frame remains intact and the data is
simply inserted into the stream between frames. If data is entered inside a frame, the
frame structure may be corrupted. This is often indicated to the user by highlighting the
CDB (H) field in red with the message "Frame data is incomplete."
Modifying Data Within a Pattern
LeCroy Corporation 51
The data pattern can be modified directly by double-clicking on the data cell in the top
containing that value, then typing in the new value. If in Waveform, Binary (10), KD or
10bit (3FF) mode, the new value can be entered directly into the cell. If in SC or US
mode, the user can type the new K-code or D-code values directly into the cell, or use
the drop-down menu to get a list of valid values.
Again, if the data is located within a frame, modifications may render the CRC invalid or
may corrupt the frame. This will be indicated by the frame summary in the bottom half of
the window.

Chapter 9: Analysis and Reports
A wide variety of different graphs and reports are available to help the user analyze data
collected by the PeRT
under the Analysis tab in the System Control Ribbon.
Note: During the actual running of a test, the test
3
Eagle Test System. These graphs and reports are selectable
can be monitored in a variety of ways. A
useful way to monitor the results while a
test is running is to check the Auto display
graph box in the Default Settings panel
under the Options tab. This will display the
test results as they are being collected, and
allows the user to view the results in
different formats. Once the test is started,
the user can select a different display graph
format by clicking on the Analysis tab and
selecting a different display in the Graph Type panel.
System Control Ribbon -- Analysis Tab
The Analysis tab of the System Control Ribbon contains five panels to display test status
and to allow the user to examine test data in a variety of ways.
Master Controls
The Master Controls panel under the
Analysis tab contains the same indicators
and controls that are located in the Master
Controls panel under the Main tab.
Graph Type
The Graph Type panel allows the user to select from a range
of charts and reports. These are described in more detail in
the following section.
LeCroy Corporation 53
Version 1.6 PeRT3 Eagle User Manual
Data Set
The Data Set panel allows the user to select between distinct sets of data.
For example, if a JTOL test was run twice while varying the frequency and
amplitude of sinusoidal jitter, once with SSC on and a second time with
SSC off, this would form two distinct sets of data within the same Test
Report. The user would then be able to specify which of the two data sets
to graph using the drop-down menu in the Tes t Case field for the channel
they want to graph.
The user can also specify which channel data to graph by clicking on the
channel select button in the Data Set panel.
Signal Parameters
When the user selects a specific test case to graph, the Signal Parameters panel will
display the values of the signal parameters for the selected test case.
Depending on the data contained in the selected test case and how the data is being
graphed, the user may be able to further refine what is being graphed. For example, in
the case mentioned above of the two JTOL tests, if they are graphed as scatter graphs
or two-parameter graphs, selecting the test case will completely specify the graph.
However, graphing the same test case as a single parameter graph, such as sinusoidal
jitter amplitude vs. BER, specifies a whole range of graphs (one for each sinusoidal jitter
frequency) which the user can select between by selecting a specific sinusoidal jitter
frequency in the Signal Parameters panel.
Tools
The Tools panel provides a set of tools for examining graphs in detail. The
tools include Region Select, which allows the user to select a specific region
on the chart; Scroll Graph, which allows the user to scroll around a magnified
graph; Zoom In to magnify sections of graphs; and Zoom Out to reduce
magnification.
54 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
When a region of the graph is selected using
the Region Select tool, the user is given the
options of creating a new test script to test just
the region selected, to adjust a manual test
case to cover just the region selected, or to
zoom in to that specific area of the chart.
Analysis Graph Types
Within the Graph Type panel of the Analysis tab, there are multiple choices of ways to
view your data. Each of these will be demonstrated using a sample test, which in this
case is a typical jitter tolerance test for a receiver system, for PCI Express over four
channels. This test script is called "PCIe 5.0G x4 JTOL". This script determines the
performance envelope of a receiver system by testing BER with added signal
impairments of high frequency sinusoidal jitter of 1 to 100 MHz at signal amplitudes from
0 to 180 ps. This creates a matrix of individual test cases that collectively describe the
performance envelope of the receiver system.
The choices for displaying the data are as follows:
Log View This creates a text listing of each specific test case, including
the system settings for that test case and the results obtained.
In this selection, the remaining fields in the Graph Type panel
are not used.
LeCroy Corporation 55
Version 1.6 PeRT3 Eagle User Manual
Spreadsheet View
This creates a text listing, in comma-delimited format, of test
settings and results for each test case. In this selection, the
remaining fields in the Graph Type panel are not used.
The spreadsheet view can be exported as a CSV file suitable
for import into Microsoft Excel or any program which import
comma delimited files. To export the spreadsheet view, select
Export current document from the Export option under the
main file menu (accessible from the round Eagle button in the
upper left corner of the application.
Errors vs. Time
With this selection, a chronological graph shows the errors and
BER. Error and BER data is recorded and graphed at the end
of each test case, or once per minute during test cases that last
more than one minute There is a horizontal line indicating the
BER threshold; the vertical position of this line can be changed
by entering a new value into the Threshold field. Channels can
be added to or removed from the graph by clicking on the
channel number(s) in the Data Set panel. When first
displayed, the Errors vs Time graph defaults to showing all
available channels. When switching between graphs, the new
view will show just the channel(s) that were being displayed in the previous graph.
56 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
Single Parameter
This allows a graph of a single jitter or signal parameter
variable (selected from a test matrix) vs. BER. Selecting this
option allows the user to specify the parameter to be used (the
second field in the panel), and populates the Data Set boxes
to show other parameters tested, allowing the user to specify
fixed values of other parameters to select the specific data set
of interest. The BER threshold displayed can be changed by
typing a new value into the Threshold field. Additional
channels can be displayed by clicking the channel number(s)
in the Data Set panel.
LeCroy Corporation 57
Version 1.6 PeRT3 Eagle User Manual
Multi Single Parameter
Two Parameter
This graph allows the display of multiple values of any single parameter. For example, in
the graph shown above (Single Parameter) only one value (1.0 MHz) of the available
values for high frequency SJ amplitude. The Multi Single Parameter graph below shows
all available values.
The Two Paramete r graph shows a matrix of two parameters
with BER shown as a series of colors scaled to the threshold
BER value entered in the Threshold field. The user can select
which two parameters to use for the graph in the drop-down
menu in the second field, and also select nominal values for
other parameters in the Data Set panel. Only one channel at
a time may be graphed, selected by clicking on the channel
number in the Data Set panel.
58 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
Scatter Chart
The Scatter Chart provides a means of displaying the results
of two different variables using the Threshold value as a
"Go/No-Go" gauge of performance. The second field in the
Graph Type panel can be used to select which two variables
form the axes of the chart, and the Threshold value changed
to display different settings. If more than two parameters are
varied, the nominal settings for other values can be selected
from the Data Set panel. Only one channel at a time can be
graphed, by clicking the channel number in the Data Set
panel.
Test Report The Test Report option allows the user to select from a series
of pre-defined test reports to provide automated results in the
form of a formal report. Select from one of the test reports
formats displayed in the drop-down menu of the second field.

new shortcut key: and the next key (or key combination, such as Shift+Alt+E) that you
press will be entered into this field. To assign this key (or key combination) to this
command, click the Assign button. The new custom keyboard shortcut will appear in the
list under Current Keys whenever this command category is selected.
Once you have assigned your keyboard command shortcut(s), click on the Close button,
then on the OK button in the Customize window to save your changes.
The System Control Ribbon
The System Control Ribbon is fixed in location across the top of the PeRT3 main
application window, but the ribbon will change in appearance based on the currently
selected width of the main application window. The system attempts to provide as much
information on tabs (and panels and field names within panels) as space permits.
64 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
The normal appearance (when the Main tab is selected) of the System Control Ribbon is
as follows:
There are multiple panels within the System Control Ribbon. When the Main tab is
selected, these panels include Master Controls, PeRT
3
Selection, Configuration, DUT
Initialization and DUT Status. The functions of these panels (and of the other tabs) are
described in “System Control Ribbon - Main Tab” on page 23.
If the PeRT
3
main application window is not wide enough to display all five panels, the
panels will adopt a condensed appearance, starting with the panel on the far right, in
order to fit the available space. The System Control Ribbon will then appear as follows:
To access any of the condensed panels, click on the green button that shows in the
condensed and the full panel will appear:
Commands and fields available within that panel can then be accessed, and the panel
will re-condense if the green button is pressed again or if you click anywhere outside the
area of the expanded panel.

Version 1.6 PeRT3 Eagle User Manual
Customizing the Main Library and Output Windows
As noted in the overall description of the user interface, there are additional windows
which appear in the PeRT
windows. The functions of these windows are described in detail in “Main Library
Window” on page 37 and “Analysis and Reports” on page 53.
The Main Library window appears by
default "docked" to the lower left edge of the
main application window, stretching from the
bottom of the main application window to the
bottom of the System Control Ribbon. This
window can be dragged off to create a
"floating window" and can then be
repositioned anywhere on the user’s screen.
The Output window provides a log file of
events during a test, and appears as shown
below. By default, the Output window is
docked to the bottom of the main application
window, but as with the Main Library
window, the Output window can be dragged
to a new location to create a floating window.
3
application. These include the Main Library and Output
One issue to be aware of is that if the user drags either the Main Library window or the
Output window from its "docked" position, the Test Scripts, Test Patterns or Test
Results window will expand to fill the new space, and may be partially obscured if any
part of a "floating" window covers this space.
The Main Library and Output windows can be made to disappear by clicking the close
button in the top right of the window, and to appear or disappear though the use of the
Options tab in the System Control Ribbon. Clicking on the Options tab produces the
following display:
The View panel within the Options tab provides the ability to show or to hide the Main
Library or Output windows by checking the checkbox next to the name of the window.
66 LeCroy Corporation
PeRT3 Eagle User Manual Version 1.6
Selecting the Style Color Theme
Also in the View panel within the Options tab is the ability to select a color theme for the
3
PeRT
application by clicking on the "Style" drop-down menu.
Clicking on this menu reveals the color theme choices
shown on the left.
The color themes shown are purely for personal preference
and result in no change in function for any software
selections or commands. The only difference is the
appearance of the screens as displayed to the user. Shown
below is the same displayed in the four different color
themes.
