LabMaster 10 Zi Overview

LabMaster 10 Zi is a unique modular oscilloscope solution that allows a
configuration of more channels at higher bandwidths than conventional
four channel oscilloscopes. It is ideally suited for test situations where there
are many lanes of serial data to be captured and analyzed simultaneously,
where crosstalk analysis is performed, or for capturing four or more
channels at the highest-possible bandwidths for optical coherent
modulation applications. Each LabMaster consists of a single Master Control
Module, additional Acquisition Modules, and a ChannelSync Mainframe Hub
in systems where more than five acquisition modules are required.
Acquisition Modules can be added at any time for easy channel upgrades.
Bandwidth upgrades are available for future scalability.

Unique ChannelSync™ architecture ensures precise synchronization
between all oscilloscope channels located in different acquisition modules.
A single 10 GHz distributed clock signal is generated in the MCM-Zi Master
Control Module, and then used in or distributed to as many as twenty 10­xxZi Acquisition Modules. The 10 GHz clock frequency - 1000 times faster
than the 10 MHz reference clocks commonly used to synchronize lab
equipment - ensures precise synchronization and high-timebase accuracy
between all acquisition modules. Additionally, a single trigger signal is used
for all acquisition modules to completely eliminate trigger jitter between
modules, such as would be found when two conventional oscilloscopes are
synchronized with 10 MHz clocks and a common trigger signal. The system
also ensures Acquisition Modules are automatically identified to the Master,
and software de-skew calibration routines allow for fast calibration and
correction for any static acquisition skew between all acquisition modules.

The 10-xxZi Acquisition Modules are available in a variety of bandwidths and
channel density configurations. The example below contains a mix of 36 GHz
and 65 GHz models. Refer to specifications on the product datasheet
maintained at www.teledynelecroy.com for more information.

Detailed steps explaining how to configure hardware are covered in
LabMaster Setup on page 16.

configurations. I/O panels are located on the back of the Master Control
Module. See Back of MCM-Zi Master Control Module (on page 10) for more
information.

NOTE: The MCM-Zi motherboard is a server-class motherboard with certain I/O
capabilities (serial port, VGA/WXGA video output) that are not utilized by the MCM­Zi, even though the physical connectors remain on the I/O panel. The 9-pin serial
port is used for communication to the server motherboard, and the 15-pin video
connector only outputs text debug messages from the motherboard. Since these
capabilities are not useful for the MCM-Zi, they are disabled in the BIOS and will not
provide any I/O should you connect to them.

Signal Inputs

Probes

Teledyne LeCroy offers a variety probes for use with your oscilloscope. The
types compatible with the LabMaster 10 Zi are listed below. Visit
teledynelecroy.com for specifications and ordering information.

 Single-Ended - A single-ended, active probe is associated with

measuring voltages at high frequencies. Measurement with an active
probe requires a test point and a ground point. The ground (also
called earth) acts as a zero reference for the test point measurement.
These probes are typically low-bandwidth and require an adapter to
connect to the 2.92 mm and 1.85 mm interfaces on the 10-xxZi
Acquisition Modules.

 Differential Probes - Differential active probes are like two probes in

one. Instead of measuring a test point in relation to a ground point
(like single-ended active probes), differential probes measure the
difference in voltage of a test point in relation to another test point.
Some models of differential probes may require an adapter to
connect to the 2.92 mm and 1.85 mm interfaces on the 10-xxZi
Acquisition Modules.

Interfaces

LabMaster 10 Zi systems are equipped with a variety of interfaces to allow
you to connect cables directly to the oscilloscope channels, reducing the
need to use costly adapters that may be easily lost or misplaced.

The inputs power the probe and completely integrate the probe with the
oscilloscope channel in a number of ways:

 Upon connection, the probe is recognized and some setup

information, such as input coupling and attenuation, is performed
automatically.

 System (probe plus oscilloscope) gain settings are automatically

calculated and displayed based on the probe attenuation.

Getting Started Manual

922561-00 Rev A

31

 Most active probes match probe to oscilloscope response

automatically using probe response data stored in an on-board
EEPROM. This ensures the best possible combined probe plus
oscilloscope channel frequency response without the need to
perform any de-embedding procedure.

Interfaces differ in bandwidth capabilities, so the interfaces contained on
your oscilloscope—and their exact location—depend on the bandwidth
rating of the oscilloscope model you purchased.

High-bandwidth interfaces ( 45 GHz and up) must be enabled by selecting
the appropriate Dual Bandwidth Interleave setting on the Timebase dialog
and the Input B setting on the Channel dialog.

ProBus Interface

LabMaster 10xxZi Acquisition Modules rated to 36 GHz use the ProBus
interface for AUX In and AUX Out connections. These connectors are
located on the front of the unit next to the channel inputs.

The ProBus interface contains a 6-pin power and communication connection

and a BNC signal connection to the probe. It offers both 50 Ω/1 MΩ input

impedance and provides probe power and control for a wide range of
probes such as high impedance passive probes, high impedance active
probes, current probes, high voltage probes, and differential probes. ProBus
also includes sense rings for detecting passive probes. The ProBus interface
may also have a BNC-terminated cable connected directly to it.

ProBus is based on a BNC connector and, depending on the exact BNC
connector used and the oscilloscope design, is rated for up to 4 GHz with 50
Ω coupling or up to 1 GHz for 1 MΩ coupling.

2.92 mm Interface

All LabMaster 10xxZi Acquisition Modules use the 2.92 mm interface to
input signals up to 36 GHz on channels 1-4, input A. This interface consists
of a precision connector and a LEMO power and communication connector.
It offers 50 Ω input impedance only.

LabMaster 10 Zi Oscilloscopes

32

922561-00 Rev A

The 2.92 mm high-bandwidth electrical paths are comprised of two
connector halves/subassemblies which have a common mating interface:

 The first connector half is mounted onto the oscilloscope connector

panel. The outer end of this connector has a combination of
grooves, external threads and a coaxial interface with a 2.92 mm
airline geometry.

 The second connector half is the connector saver. It has a similar

interface on one end, with spring-biased inner and outer contacts.

The connector saver has projections which interlock with slots on the
mounted connector and a coupling nut which secures the two halves;
resulting in a non-rotational, torque independent electrical connection. The
spring-biased inner and outer contacts eliminate the need for specifying
proof torque and no tools are required to mate or un-mate the connection.

The connector saver is easily field replaceable, should damage occur,
making it a more field reliable system. The 2.92 mm connector saver
operates mode free well beyond 36 GHz.

1.85 mm Interface

LabMaster 10xxZi Acquisition Modules rated over 36 GHz use the 1.85mm
interface for 50-65 GHz inputs (channels 2 and 3, input B). This interface
consists of a precision V-male connector with a V-female to V-female barrel
adapter and a LEMO power and communication connector. It offers 50 Ω
input impedance only. The barrel adapter is easily field replaceable, should
damage occur.

The male connector is mounted onto the oscilloscope connector panel
when delivered. The female-female barrel adapter must be manually
attached before connecting cables.

Getting Started Manual

922561-00 Rev A

33

To attach the female-female barrel adapter:

1. Remove the white cap from the V-male connector on the high

bandwidth input of the 10-xxZi acquisition module. Turn it
counterclockwise to loosen it.

2. Insert the female-female barrel adapter into the V-male connector.

LabMaster 10 Zi Oscilloscopes

34

922561-00 Rev A

3. Gently turn the V-male connector in the counterclockwise direction

until it is finger tight.

4. Insert the hand wrench over the flat portion of the barrel adapter.

This will hold the barrel adapter still while the V-male connector is
tightened around it.

Getting Started Manual

922561-00 Rev A

35

5. Tighten the V-male connector around the female-female barrel

adapter using the torque wrench in a counterclockwise motion.

CAUTION. Hold the torque wrench at the end or you may apply too
much force. When the torque wrench bends at the moment arm, it

is tightened to the right amount of force. Do not tighten further.

6. Connect a cable to the barrel adapter, and use the torque wrench to

tighten it.

To remove the female-female barrel adapter: Reverse the steps above,
turning the V-male connector clockwise to loosen it. Be sure to turn the V­male connector and not the barrel adapter. You may have to manually keep
the torque wrench from bending while loosening the connector.

Probe Dialog

Teledyne LeCroy proprietary probe interfaces provide a complete
measurement solution from probe tip to oscilloscope display. The Probe
Dialog displays probe attenuation and other information, and allows you to
make tip select and other probe settings from the oscilloscope touchscreen.

The following figure shows a typical channel dialog on a Teledyne LeCroy
oscilloscope containing both 2.92 mm (Input A) and 1.85 mm (Input B)
interfaces. The input selection is on the left-hand side of the dialog box.

Combining Channels

Digital Bandwidth Interleave (DBI) is a method for combining channels to
double or triple bandwidth, sample rate, and memory lengths - just as
oscilloscope manufacturers have for years interleaved channels to increase
sample rate and memory.

When you make DBI selections, some system values are changed. View
these changes by touching the trace descriptor label for an interleaved
channel. In particular, The Vertical Scale B Scale V/div (Timebase) value is
automatically set to 50 mV/div. If you set this to a different value after
deactivating DBI, the system resumes the last one used with DBI when DBI is
reactivated.

1. Choose TimeBase → Horizontal Setup... to access the Timebase

dialog.

2. If you have more than one Acquisition module, touch the DBI tab to

show the DBI dialog. Otherwise, use the Digital Bandwidth Interleave
area to the far right of the Timebase dialog.

3. Select the inputs to combine by touching the corresponding higher

bandwidth button beneath the pair (in the image below, 36 GHz C1
and C2 are combined into one 65 GHz C2). The active input is
highlighted. Combinations can be made in one or all modules.

4. The respective channels are combined into higher bandwidth

channels, labeled "Input B".

5. On the Channel setup dialog, select Input B.

NOTE: Use Channel 4 for high-speed serial triggering, even in cases where the

oscilloscope is operating in 50, 60, or 65 GHz modes.

Sampling Modes

Depending on your timebase, you can choose:

Real Time Sampling Mode (below) - Also known as single-shot sampling
mode, a series of digitized voltage values sampled on the input signal at a
uniform rate.

Sequence Sampling Mode (on page 59) - Many trigger events stored as
segments into the oscilloscope's memory.

Selecting a Sampling Mode

1. Touch Timebase → Horizontal Setup... from the menu bar.

2. On the Timebase dialog, select a Sample Mode.

3. If you chose Sequence Mode, touch the Sequence tab and provide

values for Number of Segments, Enable Timeout, Timeout (value),
Display Mode, and Show Sequence Trigger Times.

Single-shot Sampling Mode

A single-shot acquisition is a series of digitized voltage values sampled on
the input signal at a uniform rate. It is also a series of measured data values
associated with a single trigger event. The acquisition is typically stopped a
defined number of samples after this event occurs: a number determined by
the selected trigger delay and measured by the timebase. The waveform's
horizontal position (and waveform display in general) is determined using
the trigger event as the definition of time zero.

You can choose either a pre- or post-trigger delay. Pre-trigger delay is the
time from the left-hand edge of the display grid forward to the trigger
event, while post-trigger delay is the time back to the event. You can sample
the waveform in a range starting well before the trigger event up to the
moment the event occurs. This is 100% pre-trigger, and it allows you to see
the waveform leading up to the point at which the trigger condition was
met and the trigger occurred. (The instrument offers up to the maximum
record length of points of pre-trigger information.) Post-trigger delay, on

Getting Started Manual

922561-00 Rev A

59

the other hand, allows you to sample the waveform starting at the
equivalent of 10,000 divisions after the event occurred.

On fast timebase settings, the maximum single-shot sampling rate is used.
But for slower timebases, the sampling rate is decreased and the number of
data samples maintained.

The relationship between sample rate, memory, and time can be simply
defined as:

Capture Interval = 1/Sample Rate X Memory

and

Capture Interval/10 = Time Per Division

Sequence Sampling Mode – Working with Segments

Using Sequence Mode, thousands of trigger events can be stored as
segments into the oscilloscope's memory (the exact number depends on
oscilloscope model and memory options). This is ideal when capturing many
fast pulses in quick succession or when capturing few events separated by
long time periods. The instrument can capture complicated sequences of
events over large time intervals in fine detail, while ignoring the
uninteresting periods between the events. You can also make time
measurements between events on selected segments using the full
precision of the acquisition timebase.

Sequence mode offers a number of unique capabilities:

 You can acquire up to four channels simultaneously.
 You can minimize dead time between trigger events for consecutive

segments.

 You can view time stamps for acquisitions.
 You can zoom segments or used them as input to math functions.
 You can combine sequence mode with an advanced trigger to isolate

a rare event, capture all instances over hours or days, and
view/analyze each afterwards.

LabMaster 10 Zi Oscilloscopes

60

922561-00 Rev A

 You can use Sequence mode in remote operation to take full

advantage of the instrument's high data-transfer capability.

In Sequence mode, the complete waveform consists of a number of fixed­size segments acquired in single-shot mode (see the instrument
specifications for the limits). The oscilloscope uses the sequence timebase
setting to determine the capture duration of each segment as 10 x time/div.
With this setting, the oscilloscope uses the desired number of segments,
maximum segment length, and total available memory to determine the
actual number of samples or segments, and time or points.

SEQUENCE DISPLAY MODES

The instrument gives you a choice of five ways to display your segments:

 Adjacent

 Waterfall (cascaded)

 Mosaic (tiled)

SEQUENCE MODE SETUP

When setting up Sequence Mode, you define the number of fixed-size
segments acquired in single-shot mode (see the instrument specifications
for the limits). The oscilloscope uses the sequence timebase setting to
determine the capture duration of each segment. Along with this setting,
the oscilloscope uses the number of segments, maximum segment length,
and total available memory to determine the actual number of samples or
segments, and time or points.

Setting up Sequence Mode (Adjacent)

1. Touch Timebase → Horizontal Setup... on the menu bar.

2. Click the Sequence tab.

3. Under Acquisition Settings, touch inside the Num Segments data

entry control and provide a value using your preferred input control
method. Additional information on using the touch screen controls
can be found in the Dialog Area.

NOTE: The number of segments you choose to display can be less than the

total number of segments in the waveform. For example, in the pop-up
images above, the number of display segments is 10, but the total number
of segments entered in Num Segments on the Timebase dialog is 100.

4. Touch the Enable Timeout checkbox.

5. Touch the Timeout data entry control and provide a timeout value.

NOTE: Use the sequence mode timeout to automatically interrupt the

sequence acquisition if the timeout value is exceeded without a valid trigger.
The timeout period accounts for instances when a Num Segments
miscount occurs for some reason and the oscilloscope waits indefinitely for
an unforthcoming segment. During that time, no oscilloscope functions are
accessible. By means of a timeout value, however, the acquisition will be
completed, the waveform displayed, and control of the oscilloscope
returned to the user after the timeout has elapsed.

6. Under Display Settings, touch the Display mode control, and select a

sequence mode display from the pop-up menu.

NOTE: Once a single acquisition has started, you can interrupt the

acquisition at any time by pressing the SINGLE front panel button a second
time or by pressing the STOP front panel button. In this case, the segments
already acquired will be retained in memory.

7. Touch the SINGLE trigger front panel button.

Vertical

You can access Vertical settings using the front panel Vertical controls, by
selecting Vertical→ Channel Setup... on the menu bar, or by touching the
Channel trace descriptor label. The following screen-shot shows the C1
dialog on a LabMaster. For each open channel trace, a corresponding Cx
dialog opens with setup controls.

The Channel dialog also lets you perform certain actions on the channel
trace, such as Math and Measure, without having to leave the dialog.

NOTE: For LabMaster, the ChannelSYNC Calibration dialog provides another

vertical set up option.

Channel Dialog

The Cx tab of the dialog provides the following functions for the respective
channel:

 Selected Input - For each channel, you can set the Channel Input to

either Input A (Upper) or Input B (Lower). The Channel Row LED
Indicators display which input is set for each channel.

NOTE: Not all oscilloscope models have Upper and Lower Channel Inputs. In

those cases, no Selected Input buttons are provided. The Acquisition

Modules indicate alternative, or B channels, on named LED
indicators.

 Vertical Scale - For each channel, you can set the vertical scale or

sensitivity and choose whether to use fixed or variable gain
adjustment.

 Vertical Offset - For each channel, you can select between zero

vertical offset or to set the offset to a specific value.

 Coupling - The maximum input voltage depends on the input used.

Values are displayed on the front of the oscilloscope. Whenever the

LabMaster 10 Zi Oscilloscopes

68

922561-00 Rev A

voltage exceeds this limit, the coupling mode automatically switches
from DC 50 Ω to GROUND. You then have to manually reset the
coupling to DC 50 Ω.

CAUTION While the unit does provide this protection, damage

can still occur if extreme voltages are applied

 Bandwidth - Bandwidth filters are available at a variety of fixed

bandwidth settings. The exact settings vary by model.

 Probe - Teledyne LeCroy's 1.85 mm and 2.92 mm probe inputs

automatically senses probes and sets their attenuation for you. For
each channel, the probe attenuation can also be set manually.

Pre-Processing Controls

Pre-Processing means “before Math processing.” Pre-Processing controls
provide the following functions for your respective channel:

 Averaging - Specifically performs continuous averaging or the

repeated addition, with unequal weight, of successive source
waveforms. It is particularly useful for reducing noise on signals
drifting very slowly in time or amplitude. The most recently acquired
waveform has more weight than all the previously acquired ones: the
continuous average is dominated by the statistical fluctuations of the
most recently acquired waveform. The weight of old waveforms in

Getting Started Manual

922561-00 Rev A

69

the continuous average gradually tends to zero (following an
exponential rule) at a rate that decreases as the weight increases.

 Deskew - Adjusts the horizontal time offset by the amount entered.

The valid range is dependent on the current timebase setting. Pre­processing deskew and the Math deskew function perform the same
activity.

 Invert - Invert the waveform for the selected channel.
 Cable De-Embedding - When measuring serial data signals,

propagation delays from the test cables can reduce the accuracy of
your signal (for example, signal amplitude and risetime), as well as
introduce Inter-Symbol interference. These cable effects can
dramatically alter your serial data measurements and potentially
create mask test violations. The Cable De-Embedding option allows
you to quickly specify the characteristics of the cables (typically found
on the cable's data sheet) in your test setup and analyze your signal
with the effects of the cables removed.

NOTE: The Cable De-Embedding checkbox is only visible with this option.

 Interpolation - Linear interpolation, which inserts a straight line

between sample points, is best used to reconstruct straight-edged
signals such as square waves. (Sinx)/x interpolation is suitable for
reconstructing curved or irregular wave shapes, especially when the
sample rate is 3 to 5 times the system bandwidth.

 Noise Filter - Enhanced Resolution (ERES) filtering increases vertical

resolution, allowing you to distinguish closely spaced voltage levels.
The tradeoff is reduced bandwidth. The functioning of the
instrument's ERES is similar to smoothing the signal with a simple,
moving-average filter. Use ERES on single-shot waveforms, or where
the data record is slowly repetitive (when you cannot use averaging).
Use it to reduce noise when your signal is noticeably noisy, but you
do not need to perform noise measurements. It also may be used
when performing high-precision voltage measurements: zooming
with high vertical gain, for example.

 Optimize - See Response Optimization Modes.

LabMaster 10 Zi Oscilloscopes

Response Optimization Modes

Frequency response and group delay of the oscilloscope contributes to the
pulse response characteristics of the oscilloscope. By slightly adjusting these
characteristics using digital signal processing, the characteristic response of
the oscilloscope can be optimized for your specific application.

Frequency response is defined as the decrease in the magnitude response
with respect to frequency. A fourth-order Bessel roll-off slightly attenuates
the frequencies near the bandwidth rating of the oscilloscope while a brick­wall frequency response passes slightly higher frequency content.

Group delay is defined as the rate of change of the total phase shift with
respect to angular frequency through a device or transmission medium.
Amplifiers in analog oscilloscopes typically have some group delay at the
highest frequencies. This inherent group delay minimizes the preshoot
present on a step response and provides the traditional pulse response with
no preshoot before the step. When zero group delay is provided at all
frequencies, preshoot and overshoot is equalized.

Teledyne LeCroy provides three choices for response optimization. Each
combines a frequency and group delay response to optimize the
oscilloscope for particular applications.

Pulse Response. A group delay compensation minimizing
preshoot, this selection most resembles the response of an
analog oscilloscope by controlling group delay to be slightly
non-zero at the highest frequencies. In addition, a fourth­order Bessel frequency response is implemented.

Eye Diagram. Flat group delay compensation resulting in
equalized preshoot and overshoot. This selection improves
the symmetry of serial eye diagrams. In addition, a fourth­order Bessel frequency response is implemented.

Flatness. Flat group delay compensation with a brick-wall
frequency response. While this provides the fastest rise time,
there is also a slight penalty of more preshoot and overshoot
compared to Eye Diagram mode. This selection is most often
used in narrow-band RF measurements where it is desirable

to maintain constant magnitude response over the oscilloscope passband.

LabMaster Deskew Calibration

The ChannelSync™ architecture in LabMaster modular oscilloscope systems

utilizes a single 10 GHz distributed clock for all acquisition modules. This
provides precise timing alignment and timing accuracy between all channels
in all acquisition modules as found in a single, conventional oscilloscope
package. However, to ensure that the static skew of all connecting cables is
accounted for, a calibration is required for the most accurate results.

Deskew calibration eliminates:

 Static skew due to minor differences in length of PCIe

interconnection cables. LabMaster modular oscilloscopes may consist
of multiple acquisition modules. These multiple modules need to
deskewed with respect to each other to account for connection cable
propagation delay (static skew). This propagation delay is normally
100-200 ps and is a result of the very small differences in length
between the PCIe cables used for connections on your particular
LabMaster setup.

 Minor static skew differences between channels and gain settings in

a single acquisition module.

 The small amount of static skew remaining after the factory

hardware deskew. At the factory, channels in each Acquisition
Module are deskewed in hardware to within approximately 2 ps at 20
GHz. This can vary slightly over varying gain ranges (V/div settings) on
each channel. Depending on the timing accuracy desired for your
measurements and the bandwidth of your acquisition module, you
may need to correct for this.

 Static skew introduced by probe and cable connections. With probes

and cables connected to the acquisition module, additional static
skew will be introduced. When these devices are attached, deskew
signals must be respectively deskewed to each other is again
required to eliminate the propagation delay of the signal due to
these items being added to the signal path.

Getting Started Manual

922561-00 Rev A

73

There are two different deskew calibrations that can be performed. Both
permit quick and easy deskew of all of the channels in all LabMaster
acquisition modules by automatically deskewing all channels to a user­designated reference channel, with the common deskewed reference plane
being the input channel connectors on the acquisition module. A very high
level of accuracy is maintained by using a fast reference signal and
averaging for precision.

SystemSkew Cal

For a given LabMaster setup consisting of more than one acquisition
module, this calibration provides the fastest and easiest way to eliminate
the static skew caused by all PCIe interconnection cables and align trigger
positions on all modules. The SystemSkew Cal need only be performed once
at initial setup as long as the cables or the acquisition modules do not
change. If the LabMaster system you're using has only one acquisition
module, a SystemSkew Cal provides no value.

During SystemSkew Cal, you are instructed to connect the Fast Edge output
to one channel on each acquisition module in a prescribed manner. All static
skew adjustments are saved in a calibration folder. The values for this static
skew calibration are not displayed in the ChannelSync Cal dialog. If the
LabMaster system on startup detects a configuration change (e.g. a
different serial number acquisition module connected to a certain PCIe slot),
a pop-up dialog will appear warning the user to perform a new SystemSkew
Cal.

Fast Edge output to Channel 5. After connecting, touch Next again.

5. Continue following on-screen prompts for as many additional

modules there are.

6. When completed, touch Finish to apply and store all corrections.

ChannelSync Cal

This calibration method is most common and is used to eliminate minor
static skew (<2 ps) differences between channels or to account for the
addition of cables or probes between the signal and oscilloscope input
channel. When Channel Sync Cal is complete, jitter between all channels is
adjusted to a level comparable to a single conventional oscilloscope package
, or better than 275 fs RMS.

NOTE THE FOLLOWING about ChannelSync Cal prior to performing the
procedure:

 ChannelSync Cal can be performed on different gain settings by

using an attenuator (that you supply) to reduce the amplitude of
the Fast Edge output. Choose an attenuator value that provides for
a Fast Edge signal amplitude of ~4 to 7 divisions.

 If you perform ChannelSync Cal only on the 100 mV/div gain range,

there is no need to enter a “Reference Correction” (attenuator

propagation delay value).

Trigger

Trigger Overview

NOTE: Trigger capabilities on channel 1-4 (i.e., the first acquisition module) are

more complete than on channels 5 or higher. Full Edge trigger bandwidth is
available on all channels, but SMART triggers are not available on Channel 5 or
higher.

Triggering is the way an oscilloscope selects an exact moment in time of a
signal to then be shown on the screen. If the signal pattern happens to be
repetitive, a continuous waveform pattern is visible on the display. But
without a regular signal pattern, the oscilloscope requires controls to
determine what specific point in time (when a trigger is met) to show the
signal on the display. This is accomplished and affected in a variety of ways.

Some trigger settings allow for pre-trigger, post-trigger, and a delay
between the time of the trigger event and the time when the display is
refreshed (or sweeped) and the waveform is again shown on the screen.
The instrument uses many waveform capture techniques that trigger on
features and conditions that you define. These triggers fall into the
following major categories:

 Simple Triggers - activated by basic waveform features or conditions

such as a positive or negative slope, and hold‐off

 SMART Triggers - sophisticated triggers that enable you to use basic

or complex conditions for triggering. Use SMART Triggers for signals
with rare features, like glitches.

 Measurement Trigger - triggers that allow you to leverage parameter

measurements as waveform trigger conditions. A measurement
trigger is either the only trigger or the final trigger in a chain of
trigger events including hardware triggers.

 MultiStage Triggers - varied forms of triggers including Cascaded,

QualFirst, and Qualified allowing varied combinations of triggers and

trigger stages.

 Serial Triggers - provide serial data protocol specific triggering for a

wide variety of standards.

LabMaster 10 Zi Oscilloscopes

80

922561-00 Rev A

Trigger Types

A set of standard trigger types is available for selection. These triggers are
basic waveform features or conditions such as a positive or negative slope
and are available on all oscilloscopes, along with tools like Software
Assisted Trigger and Trigger Scan.

There are more sophisticated triggers for setting complex conditions. These
include Smart Triggers, Serial Trigger, Measurement Triggers, and
MultiStage Triggers.

Edge

A simple trigger, Edge trigger is activated by basic waveform
features or conditions such as positive or negative slope, and
holdoff.

NOTE: Up to 15 GHz bandwidth is available while Edge Triggering (provided no

holdoff is selected).

Width

Width trigger allows you to define a positive- or negative-going
pulse width bounded by a voltage level, above or below an
occurring trigger. Or you can specify a pulse width and voltage

range, within or outside an occurring trigger.

Pattern (Logic)

Logic trigger enables triggering on a logical combination
(pattern) of five inputs: CH1, CH2, CH3, CH4, and AUX

(sometimes referred to as EXT on legacy oscilloscope models).
You have a choice of four Boolean operators (AND, NAND, OR, NOR), and
you can stipulate the high or low voltage logic level for each input
independently.

Getting Started Manual

922561-00 Rev A

81

Smart

This trigger group sets conditions on signals with rare features.

WINDOW

A trigger occurs when a signal enters or exits a window defined
by adjustable thresholds.

INTERVAL

While Glitch trigger performs over the width of a pulse, Interval
trigger performs over the width of an interval: the signal

duration (the period) separating two consecutive edges of the
same polarity, positive to positive or negative to negative. Use interval
trigger to capture intervals that fall short of, or exceed, a given time limit. In
addition, you can define a width range to capture any interval that is itself
inside or outside the specified range (an Exclusion trigger by interval).

GLITCH

Glitch trigger is a simpler form of Width trigger. Use Glitch

trigger when you want to define a fixed pulse-width time or

time range only. Glitch trigger makes no provision for voltage
levels or ranges.

DROPOUT

the last trigger source transition.

RUNT

(triggers on the slope opposite to that selected) and runt width.

Measurement

This trigger type allows you to leverage parameter
measurements as waveform trigger conditions. A measurement
trigger is either the only trigger or the final trigger in a chain of

trigger events including hardware triggers.

MultiStage

This is a set of trigger types where the trigger event depends on a series of
earlier conditions being met.

CASCADED

The Cascaded trigger allows you to define successive trigger

Stages (referred to as Stage A, B, C, and D) as arm, trigger/arm,
trigger/arm, trigger criteria, respectively.

QUALFIRST

In single trigger mode, QualFirst arms the oscilloscope on the A
event, and then triggers on all subsequent B events.

NOTE: This selection is enabled when using sequence sampling mode. It is

commonly used for disk drive applications with the index pulse defined as the A
qualifier signal and the servo gate signal as the B triggering events.

QUALIFIED A-B

In single trigger mode, Qualify A-B arms the oscilloscope on the
A event, and then triggers on the B event. If the oscilloscope is
in Normal trigger mode, it automatically resets after the B

event. Arm trigger events can be set for Edge, Pattern, State, and PatState.

STATE

The State trigger is a level-qualified trigger which requires that
the qualifying signal remain above or below a specified voltage

level for a trigger to occur. For State trigger, you specify the
time or number of events after the signal has gone above or below the
voltage level when you want the trigger to occur.

Serial Trigger

A 14.1 Gb/s Serial Trigger is optionally available for LabMaster
10 Zi. This trigger is installed in a 10-xxZi acquisition module and

is permanently connected internally for use on Channel 4 only.
The 10-xxZi Acquisition Module that contains this trigger should be the first
acquisition module (i.e. Channels 1 – 4) in any multi-acquisition module
system.

This trigger option provides capability for Non-Return to Zero (NRZ) 80-bit
pattern and 8b/10b symbol triggering. Additional capabilities are planned
for the future.

NOTE: Although 50, 60, or 65 GHz inputs operate on Channels 2 and 3 only,

Channel 4 would still be the input channel for the serial trigger signal.

Complete information on the operation of this trigger can be obtained in
the Teledyne LeCroy Serial Data Debug Solutions manual posted on the
Teledyne LeCroy website.

Trigger Settings

All trigger Horizontal and Vertical adjustments are typically made using
either the Delay or Level knobs on the front panel of the instrument, or else
the corresponding software controls on the Timebase setup dialog.

Horizontal

Turn the DELAY knob in the HORIZONTAL control group to adjust the trigger's
horizontal position. Or, touch inside the Delay control and provide a value
on the Timebase dialog using your preferred input control method.
Additional information on using the touch screen controls can be found in
the Dialog Area.

The trigger location is shown by a marker under the grid.

Post-trigger delay is indicated by a left-pointing arrow at the lower­left of the grid.

LabMaster 10 Zi Oscilloscopes

922561-00 Rev A

The time value is given in the title line of the Timebase
label at the lower-right of the grid.

Vertical

Turn the LEVEL knob in the TRIGGER control group to adjust the trigger's
vertical threshold.

Turn this knob to adjust the level of the trigger source or the highlighted
trace. Level defines the source voltage at which the trigger will generate an
event: a change in the input signal that satisfies the trigger conditions.

Alternatively, in the Trigger dialog, you can touch inside the Level control
and provide a value using your preferred input control method. Additional
information on using the touch screen controls can be found in the Dialog
Area. Quickly set a level of zero volts by touching the Zero Level button.

An arrow on the right side of the grid shows the threshold position. This
arrow is only visible if the trigger source is displayed.

Trigger Setup

Based on your Trigger Type selection, sections of the main Trigger dialog
and additional dialogs altogether vary.

Most trigger types have Type, Setup, and Level selections. The following
sections explain some of the standard setup configurations for different
trigger types.

1. Make your Type selection by touching the button corresponding to

the desired trigger.

Getting Started Manual

922561-00 Rev A

85

2. Touch inside the trigger Source control for your first Setup

configuration and select a source on which to trigger.

3. Touch inside the Coupling control and select a coupling mode.

Coupling refers to the type of signal coupling at the input of the
trigger circuit. With DC coupling, all of the signal's frequency
components are coupled to the trigger circuit for high-frequency
bursts.

4. Touch inside the trigger Slope control and choose the direction of the

trigger voltage transition used for generating a particular trigger
event.

The selection is then shown to the right of the dialog as follows for a
Positive Slope selection on an Edge Trigger.

Edge trigger works on the selected edge at the chosen level. The slope
(positive or negative) is specified on the Trigger label permanently shown
to the lower-right of the grid.

5. Level defines the source voltage at which the trigger circuit generates

an event (a change in the input signal that satisfies the trigger
conditions). The selected trigger level is associated with the chosen
trigger source. Note that the trigger level is specified in volts and
normally remains unchanged when the vertical gain or offset is
modified.

922561-00 Rev A

The Amplitude and Range of the trigger level have limits as detailed
in the datasheet specifications regularly maintained at
www.teledynelecroy.com.

Touch inside the Level data entry control and provide a value using
your preferred input control method. Additional information on using
the touch screen controls can be found in the Dialog Area.

Provide a voltage level (in millivolts).

NOTE: Once specified, Trigger Level and Coupling are the only parameters

remaining unchanged as you switch from trigger mode to trigger mode for each
trigger source.

Optimize for HF

The Optimize for HF checkbox can be used on an Edge trigger to reject high
or low frequencies.

The checkbox is marked by default; meaning, the instrument is optimized
for high-frequency waveforms.

NOTE: If you are measuring a waveform that is 10 MHz or slower, be sure to

unmark the checkbox to avoid triggering on an incorrect slope.

Width Condition

Width triggers (and other triggers equipped with conditional logic) have
conditional logic settings as follows.

Your Width Condition can be specified as Less Than, Greater Than, In Range
and Out Of Range.

Getting Started Manual

922561-00 Rev A

87

In Range and Out of Range conditions can be further specified by setting:

 Limits and assigning Upper and Lower Values to the range.
 Delta and assigning Nominal width and Delta.

NOTE: Width Condition settings are summarized on the far right of the dialog.

Holdoff by Time or Events

Holdoff is an additional condition of Edge and Pattern triggers. It can be
expressed either as a period of time or an event count. Holdoff disables the
trigger circuit for a given period of time or number of events after the last
trigger occurred. Events are the number of occasions on which the trigger
condition is met. The trigger resumes when the holdoff has elapsed and its
other conditions are met.

Use holdoff to obtain a stable trigger for repetitive, composite waveforms.
For example, if the number or duration of sub-signals is known you can
disable them by choosing an appropriate holdoff value. Qualified triggers
operate using conditions similar to holdoff.

HOLD OFF BY TIME

Sometimes you can achieve a stable display of complex, repetitive
waveforms by placing a condition on the time between each successive
trigger event. This time would otherwise be limited only by the input signal,
the coupling, and the instrument's bandwidth. Select a positive or negative
slope, and a minimum time between triggers. The trigger is generated when
the condition is met after the selected holdoff time, counted from the last
trigger. The delay is initialized and started on each trigger.

Edge Trigger with Holdoff by Time. The broken upward-pointing arrows indicate
potential triggers, which would occur if other conditions are met. The bold arrows
indicate where the triggers actually occur when the holdoff time has been exceeded.

HOLD OFF BY EVENTS

Select a positive or negative slope and a number of events. An event is the
number of times the trigger condition is met after the last trigger. A trigger
is generated when the condition is met after this number, counted from the
last trigger. The count is restarted on each trigger. For example, if the event
number is two, the trigger occurs on the third event.

Edge Trigger with Holdoff by Events (in this example, two events). The bold edges on
the trigger source indicate that a positive slope has been selected. The broken,
upward-pointing arrows indicate potential triggers, while the bold ones show where
triggers actually occur after the holdoff expires.

TriggerScan

TriggerScan is a debugging tool (available for any trigger type) that helps
you quickly find rare waveform glitches and anomalies. With TriggerScan,
you can build a list of trigger setups to look for rare events and
automatically sequence through each one. TriggerScan can use any type of
trigger setup available including edge, width, and qualify as well as Smart
Triggers (such as, glitch and runt triggers). TriggerScan automates two key
processes in triggering rare events:

 Trains the system by looking at normal acquired waveforms. During

the training, the oscilloscope analyzes the waveforms to determine
what waveforms normally look like. Using this information, it
generates a list of smart trigger setups to trigger on abnormal
situations.

 Loads the smart trigger setups from the Trainer and cycles through

these. As triggers occur, they are overlaid on the screen. All
acquisition settings are preserved and you can use all the functions of
the oscilloscope to find the root cause of these anomalies.

Training TriggerScan

The TriggerScan Trainer inspects a currently acquired waveform and
automatically builds a list of common trigger setups used to find rare
events.

NOTE: Run the Trainer if you want to change the trigger types or if you change the

channel or signal. You must acquire and display at least 3 cycles of a signal before
running the Trainer.

1. Touch Trigger → Trigger Setup... from the menu bar.

2. On the Trigger dialog, click the TriggerScan tab.

3. Touch the Trainer button and select a source channel from the pop-

up. Also choose the types of triggers the Trainer should use to train
the system and then touch the Start Training button. The training
begins. When it is complete, a list of smart trigger setups is displayed
in the Trigger List.

Starting TriggerScan

After you have run the Trainer, the Trigger List displays a list of smart trigger
setups. You can add or remove trigger setups. You can also update the
selected smart trigger setup. Once you have made any changes to the
Trigger List, you are ready to start scanning.

1. Touch Trigger → Trigger Setup... from the menu bar.

2. On the Trigger dialog, click the TriggerScan tab.

3. If you want to add a new trigger setup, touch the Trigger tab and set

the new trigger as desired on the Trigger dialog. Then, back on the
TriggerScan dialog, touch the Add New button to append the new
trigger to the Trigger List.

4. If you want to replace the selected trigger setup with the current

trigger setup, highlight the setup in the Trigger List and touch the
Update Selected button.

5. If you want to show a specific trigger setup on the Trigger List,

highlight its corresponding row on the list, and then touch the Load

Selected button.

Note: If you want to delete all trigger setups in the Trigger List, touch the
Delete All button.

6. If you want to delete a trigger setup, highlight the setup in the Trigger

List and touch the Delete Selected button.

7. All trigger setups can be deleted regardless of selections on the

Trigger List with one step by touching the Delete All button.

8. Once you have made any changes to the Trigger List, touch the

Trainer button and then restart the scan by touching the Start
Training button on the Trigger Scan Trainer pop-up. The oscilloscope
automatically sequences through all the trigger setups.
