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.

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

 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

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

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

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

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 V- male 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.

Timebase

Timebase Dialog

You can access Timebase settings by:

 Using the front panel Horizontal controls,  Choosing Timebase → Horizontal Setup... from the menu bar  Touching the Timebase trace descriptor label.

The main Timebase dialog contains sections for choosing Sampling Mode, Timebase Mode, and Real Time Memory.

A section specifically used for Combining Channels (below) is located at the far right of the main Timebase dialog. This section varies based on your oscilloscope model.

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.

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

LabMaster 10 Zi Oscilloscopes

922561-00 Rev A

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

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

 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)

 Overlay

 Perspective

NOTE: some display modes have limitations on the number of segments that can

be shown at one time.

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.

Getting Started Manual

922561-00 Rev A

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.

ZOOMING SEGMENTS IN SEQUENCE MODE

You can zoom individual segments easily using the Zoom front panel button. When you zoom, the zoom traces default to Segment 1. Channel descriptors indicate the total number of segments acquired. Zoom descriptors indicate [Seg #] and #Segments in the Zoom. You can scroll through the segments usingZoom front panel position knob.

Sample Zoom of Segments in Sequence Mode

1. Touch the front panel Zoom button.

2. Turn the ZOOM front panel position knob to scroll through the

segments.

3. To vary the degree of zoom, touch the newly created Zx trace label.

The setup dialog for the zoom (Z1 to Z4) opens. It shows the current horizontal and vertical zoom factors.

922561-00 Rev A

4. If you want to increase or decrease your horizontal or vertical zoom

in small increments, touch the Var. checkbox to enable variable zooming. Now with each touch of the zoom control buttons, the degree of magnification changes by small increments.

To zoom in or out in large standard increments with each touch of the zoom control buttons, leave the Var. checkbox unchecked.

T set exact horizontal or vertical zoom factors, touch inside the Horizontal Scale/div data entry control and enter a time-per-div value, using the pop-up numeric keypad. Then touch inside the Vertical Scale/div control and enter a voltage value.

DISPLAYING AN INDIVIDUAL SEGMENT

1. Touch Math → Math Setup... on the menu bar.

2. Touch a function tab Fx showing its corresponding dialog.

3. On the dialog, touch inside the Operator1 control and select the

Segment button from the pop-up menu.

4. In the dialog on the right, touch the Select tab.

5. Touch inside the First Selected data entry control and select the first

segment you want to display. Use the same method to provide a value in the Number of Selected data entry control.

NOTE: In Persistence mode, the segments are automatically overlaid one on top of

the other in the display. In non-Persistence mode, they appear separately on the grid.

922561-00 Rev A

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

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

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

922561-00 Rev A

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 Channel Setup

You can adjust the sensitivity and the positioning of the waveforms and set the color of the trace for up to 80 channels on the Channel Setup dialog. The example shown below illustrates Channel Setup with a 20 channel LabMaster.

1. Choose Vertical → Channel Setup... from the menu bar to open the

Channel Setup dialog.

2. Touch inside the checkbox next to a channel to display the trace.

3. To adjust sensitivity and position, turn the VERTICAL GAIN front panel

knob for the selected channel. OR Touch inside the Volts/Div field next to the channel and enter a value. Click the keypad button to enter a value using the pop-up keypad, or use the up/down arrows.

NOTE: The set voltage is shown on the trace descriptor label and in the Volts/Div field in the dialog.

4. To set the offset, turn the VERTICAL OFFSET adjust front panel knob

directly above the channel button whose waveform you want to move vertically. Or, you can touch inside the Offset field next to the channel and type in a value on the pop-up keypad. To set the vertical offset to zero, touch the Zero Offset button directly below the Offset field.

5. To change the color assigned to a channel, click on the color box and

choose a color.

NOTE: Front panel knobs can be used to adjust VERTICAL OFFSET and GAIN

for channels 5-80, provided the trace descriptor label is active for the corresponding channel.

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

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.

1. From the menu bar, choose Vertical > Channel <#> Setup. Touch the

ChannelSync Cal tab to the right of the C<#> tab.

2. Touch the SystemSkew Cal button. The System Channel/Trigger Skew

Calibration Wizard opens.

3. Connect the Fast Edge output on the front of the Master Control

Module to Channel 1, then on the Wizard touch Next. The Fast Edge output will be displayed on Channel 1 during the operation.

922561-00 Rev A

4. When the previous operation is complete, you will be prompted to

use the same cable as used to connect to Channel 1 to connect the 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).

LabMaster 10 Zi Oscilloscopes

922561-00 Rev A

 If you perform ChannelSync Cal on multiple gain settings, perform it

first on the 100 mV/div setting, then perform it on other gain

settings (with “Reference Correction” values entered as appropriate

for those other gain settings.)

 For the highest possible accuracy across the full input range of the

oscilloscope, a ChannelSync Cal should be performed on at least one gain setting in each of the following gain ranges:

2.92mm up-to-36 GHz Inputs

1.85mm up-to-65 GHz Inputs

≤10 mV/div

10.1 to 11.8 mV/div

11.9 to 17.0 mV/div

11.9 to 14.2 mV/div

17.1 to 20.5 mV/div

14.3 to 17.0 mV/div

20.6 to 30.0 mV/div

17.1 to 20.5 mV/div

30.1 to 39.5 mV/div

20.6 to 25.0 mV/div

39.6 to 50.0 mV/div

25.1 to 30.0 mV/div

50.1 to 75.0 mV/div

30.1 to 39.5 mV/div

75.1 to 90.0 mV/div

39.6 to 50.0 mV/div

90.1 to 100.0 mV/div

50.1 to 63.0 mV/div

205.1 to 250.0 mV/div

250.1 to 315.0 mV/div

315.1 to 500 mV/div

 If you add cables or probes to your setup subsequent to running the

ChannelSync Cal, you must manually deskew these items in the Channel dialog to account for their propagation delays. The values you provide on the Channel dialog (in the deskew section) are additional to values shown on the ChannelSync Calibration dialog.

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

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

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

Used primarily in single-shot applications, and usually with a pre-trigger delay, Dropout trigger can detect lost signals. The trigger is generated at the end of the timeout period following

the last trigger source transition.

RUNT

The Runt trigger occurs when a pulse crosses a first threshold

line, but fails to cross a second threshold line before re-crossing

the first. Other defining conditions for this trigger are the edge (triggers on the slope opposite to that selected) and runt width.

SLEW RATE

SlewRate trigger activates a trigger when the rising or falling

edge of a pulse crosses two threshold levels: an upper level and

a lower level. The pulse edge must cross the thresholds faster or slower than a selected period of time.

LabMaster 10 Zi Oscilloscopes

922561-00 Rev A

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.

Getting Started Manual

922561-00 Rev A

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

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.

LabMaster 10 Zi Oscilloscopes

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.

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.
