Welcome

Thank you for purchasing a Teledyne LeCroy MS-500.

The MS-500 Mixed Signal Oscilloscope Option is a powerful solution for the
challenge of measuring multiple, mixed signals in a single oscilloscope. An
enhancement to the Teledyne LeCroy oscilloscopes, the MS-500 extends
their testing range by adding 18 or 36 digital channels for display or
triggering.

The MS-500 is ideally suited for embedded controller testing where there is
a proliferation of analog signals coincident with digital signals. Users can
easily debug signals using standard oscilloscope tools such as cursors,
measurement parameters, and zooming. Both oscilloscopes compatible
with the MS-500 feature large, bright color displays to facilitate signal
viewing, plus all the connectivity and documentation capabilities needed to
quickly record and distribute information.

The MS-500 and MS-500-36 are identical except the MS-500-36 standard
configuration is for 36 channels. The MS-500-36 can be operated in 36 or
18 channel mode for higher performance. The MS-500 is configured as an
18 channel instrument and can be upgraded with an additional lead set to
support 36 channels. Both are referred to as MS-500 in this manual.

This MS-500 manual assumes that you have a basic understanding of
discrete electronics, logic analyzers, and Teledyne LeCroy oscilloscopes,
specifically the model you will use with the MS-500. When necessary,
details on specific oscilloscope features are included in this manual.

Contact your nearest Teledyne LeCroy customer service center or national
distributor if anything is missing or damaged. We can only be responsible
for replacement if you contact us immediately.

Sincerely,

David C. Graef

Teledyne LeCroy Corporation

Description of Operation

The various components of the MS-500 Mixed Signal Oscilloscope Option
acquire and store digital data, trigger on digital patterns, interface the
external module to the oscilloscope, and provide a user-friendly interface
for control and interpretation of data.

The MS-500 is an external device that digitally samples waveform data at
up to 2 GS/s (for 500 MHz digital signals). Unlike a logic analyzer, it
operates only in a Timing Analysis mode, so it requires 4x oversampling to
determine the correct digital edge position, and does not require the user
to input a clock.

While in SINGLE, NORMAL, or AUTO trigger mode, the MS-500 repeatedly
samples each digital channel’s voltage level. If the voltage is greater than
the threshold voltage, the MS-500 stores a 1 in internal memory.
Otherwise, a 0 is stored.

1

Threshold level

1 1 1 1 1 0 0 0 0 1 1 1 1 1 0 0 0 0 0

The minimum high voltage level is user definable by the hysteresis control
up to 1.4 V above the threshold. The maximum low voltage level is user
definable by the hysteresis control up to 1.4 V below the threshold. The

minimum signal swing is 100 mV. The indeterminate range of 50 mV

around the threshold voltage level is the level below which the MS-500 will

not operate. However, the MS-500 can support a signal as low as 100 mV

only if the input signal’s quality is adequate.

The MS-500 keeps sampling its inputs until the oscilloscope is put into STOP
trigger mode. Data is stored in a 50 Mpt internal memory that is
periodically transferred to the oscilloscope via the USB2.0 cable. If the
oscilloscope is triggering in SINGLE or NORMAL trigger mode, data is

Operator’s Manual

922245-00 Rev A 11

acquired and transferred only when the trigger condition is satisfied. The
captured data is then displayed on the oscilloscope grid in a time-aligned
fashion.

In any trigger mode (AUTO, NORMAL, SINGLE), pressing STOP trigger
cancels the acquisition, which leaves the previously acquired data
unchanged.

The MS-500 both samples incoming data and searches for trigger
conditions.

The USB2.0 cable provides downloading of trigger conditions from the
oscilloscope to the MS-500 and uploading of digital data from the MS-500
to the oscilloscope.

Getting Started with the MS-500

Overview

The MS-500 is a complete system that interfaces with the oscilloscope in a
number of ways that make it easier to do the following:

 Set analog, digital and combination triggers.
 View all analog and digital signal information on the oscilloscope

grid, with all signals time-correlated

All setup is done in the user-friendly oscilloscope dialogs – it is not required
to leave the oscilloscope software to run the MS-500. All normal
oscilloscope tools (cursors, measurement parameters, etc.) are available
for use with the digital signals.

There are physical connections that must be made to ensure proper
operation, but the intuitive connection steps are documented here.

Operation of the specific Teledyne LeCroy oscilloscope is not covered in
this manual. Reference the On-Line Help or Getting Started Manual for
each oscilloscope for complete information on analog triggering, display of
analog signals, front panel operation, etc.

Connecting MS-500 to the Oscilloscope

1. Connect the Teledyne LeCroy Bus Cable to the Teledyne LeCroy Bus

connector on the side of the oscilloscope and fasten the thumb
screws.

2. Connect the USB 2.0 cable (attached to the Teledyne LeCroy Bus

cable) to any of the side mounted USB ports on the oscilloscope.

3. Connect the other end of the Teledyne LeCroy Bus cable to the MS-

500 and fasten the thumb screws.

Operator’s Manual

922245-00 Rev A 13

4. Connect the other end of the USB2.0 Cable to the MS-500.

5. Connect the Digital Lead Set to the other end of the MS-500

(labeled Digital Inputs, D0 – D17) and fasten the thumb screws. For
MS-500-36 repeat this process with the lead set labeled D18 – D35.

NOTE: Each digital line has a ground connection for optimal
performance. Two additional ground leads common to the whole
lead set are also available.

6. Connect the Digital Leads to the digital lines you wish to observe

(using accessory micro-grippers, as necessary or desired).

7. Turn on power to the oscilloscope and wait for the oscilloscope

application to begin.

Verifying Proper Connection to Oscilloscope
and Device Under Test

If you are concerned that your digital signals aren’t being displayed

correctly, it is a good idea to check by viewing the digital signals one at a
time with an analog channel. This can point out errors in your connection
or in your logic threshold setup.

When your system is connected properly it looks like the following photo:

It is usually easiest to debug digital line connection or display problems by
viewing the digital information on an analog channel to confirm its
presence, then working back through the previous sequence to determine
where the connection or display error is.

CAUTION. Handle with care! The MS-500 Digital Lead Set connectors
are fragile. Pull the connector base, not the wire. Never bend the
connectors.

Operator’s Manual

922245-00 Rev A 15

Digital Connections

Channel Groupings

Each 18 channel lead set is divided into two physical groups of 9 and each
group is bundled with a plastic separator. When using 36 channels there
are 4 groups of 9 leads.

NOTE: The grouping you assign to the digital lines in the software interface
can be different than the physical grouping of digital lines. The physical
grouping is intended for easy identification of all 18 digital lines.

Connector Colors

The wires in each color group use 9 repeating colors. The color sequence
corresponds to the resistor color code making it easier to know the digital
line number without having to look at the label.

Standard Output Connection

The standard terminations on the digital lead sets can be pushed directly
onto 25-mil pins. MicroGrippers or NanoGrippers may also be used to
probe the test circuit’s pins. Teledyne LeCroy provides a selection of small,
medium, and large grippers for various pitch sizes. A more complete
selection of adapter probes is available for most chips from Emulation

Technology Inc., Yamaichi Inc., and other manufacturers.

MS-500 Mixed Signal Oscilloscope Option

922245-00 Rev A

Threshold Levels

The threshold level determines how the input signal is interpreted. The
threshold level can be set in either the Digital Grouping Setup or Pattern
Trigger Setup dialogs (it is the same setup, but is in two different places for
operator convenience). Input voltages less than the threshold are
converted to 0. Input voltages greater than the threshold are converted to

signal

Threshold level

Sample points

The threshold levels can be set between –10.0 V and +10.0 V. TTL circuits
use a threshold voltage level of 1.58 V. ECL circuits use a threshold voltage
level of -1.39 V. Other threshold settings are available in the setup dialog.

Minimum Voltage Swing

The minimum high voltage level is user definable by the hysteresis control
up to 1.4 V above the threshold. The maximum low voltage level is user
definable by the hysteresis control up to 1.4 V below the threshold. The

minimum signal swing is 100 mV. The indeterminate range of 50 mV

around the threshold voltage level is the level below which the MS-500 will

not operate. However, the MS-500 can support a signal as low as 100 mV

only if the input signal’s quality is adequate.

Operator’s Manual

922245-00 Rev A 17

Accessing the MS-500 Toolset

MS-500 trigger and digital line display tools are easily accessible in a variety
of ways. The MS-500 option adds additional dialogs (menus) to the existing
oscilloscope. These dialogs are defined as:

 Digital setup – allows set up of the Digital lines and

definition/display of parallel buses. These dialogs are roughly
analogous to the analog Channel setup dialogs in terms of how
they are accessed and how they operate in the software. However,
there are no dedicated front panel controls for digital channels as
there are with analog channels.

 Logic Setup – allows setup of the logic threshold value that defines

the digital trace.

When the MS-500 is connected to the oscilloscope, these dialogs are
conveniently accessed with just one or two touches of the screen, making
adjustment fast and easy.

MS-500 Mixed Signal Oscilloscope Option

922245-00 Rev A

Oscilloscope Analog Trigger and MS-500
Digital Trigger

The addition of the MS-500 option adds enhanced triggering; the digital
channels are now available in the oscilloscope trigger menu as trigger
sources.

To operate the oscilloscope with a normal analog trigger, simply open the
trigger dialog, and then select one of the oscilloscope channels as the
source. For more information on setting up an Analog trigger, consult your
oscilloscope On-Line Help or Getting Started Manual.

When the MS-500 is connected to the oscilloscope, the trigger type
defaults to Pattern Trigger, and the Pattern Trigger tab is automatically
displayed on the oscilloscope display dialog. If desired, touch the Close
button to not display the dialog.

For convenience, the Digital Logic Setup dialog is displayed in both the
Trigger dialogs and the Digital dialogs. Logic Setup is where you can set the
crossing threshold for determining whether the logic level is a 1 or a 0.

Other ways to access the MS-500 Trigger dialogs include:

 Touching the Trigger trace descriptor label. If the MS-500 is

connected to the oscilloscope, the dialog defaults to the Digital
Trigger tab. Follow the previous instructions to select either an
Analog or Digital trigger.

Operator’s Manual

922245-00 Rev A 19

 Touching Trigger → Trigger Setup on the menu bar. Then select

either an Analog or Digital trigger (as required).

Digital Trace Groups

These dialogs provide the ability to define up to 4 different groups of digital
signals, and associate from 1-36 digital lines with each group. Digital lines
may be associated with more than one group. As a group, the signals can
be resized, repositioned, named, stored to memory, collapsed into a bus
trace/value, or moved to a different grid (WaveRunner Xi Series only).

You can access these dialogs by touching Vertical on the menu bar, and
select one of the four Digital traces.

This turns the Digital trace ON and opens the corresponding dialog box.

MS-500 Mixed Signal Oscilloscope Option

20

922245-00 Rev A

If the Digital trace is already ON, the trace descriptor label is highlighted
and you can configure the setup dialog for that Digital trace.

The Digital trace descriptor labels contain information about the Digital
Sample Rate (top line), the maximum number of digital samples (bottom
line), and the number of channels in the grouping (top right)

Digital Trace Group Setup

Digital trace groups are very similar to analog channels – they can be
turned ON or OFF, they can be increased in size, and they can be positioned
on the grid. You can also store them as waveform files. In software, they
are accessed through the same Vertical dialog as analog channels. Cursors
and most timing measurements also work with Digital traces.

Notable differences include the lack of sampling information in the trace
data and the lack of dedicated front panel controls (though some front
panel controls double as position and size controls when the Digital trace
group is active).

However, Digital trace groups have capability far beyond that of an analog
channel. Each Digital trace group can consist of 1-36 digital lines. You can
create up to four Digital trace groups, and each digital line can be used in as
many or as few groups as desired. You can choose to display the group of

digital lines as individual digital traces (one per line), or as a “collapsed” bus

with bus data values calculated on screen within the bus trace. Since there
are so many digital lines, Digital lines or buses can be renamed so that it is
easier to keep track of the multitude of digital signals on the screen.

Operator’s Manual

922245-00 Rev A 21

Digital Trace Group Dialog

The following image shows the Digital trace group dialog with an overview
of its operation:

Provides a method to quickly turn all digital lines in the Digital trace group
OFF or ON. The default is for all digital lines to be ON. As lines are turned
OFF, they automatically resize to take up more of the grid and be easier to
see.

There are no dedicated front panel controls for Digital line
position or size. However, you can touch these controls
twice and enter in a unit-less value for position and size
using the pop-up keypad. Or you can touch them once,
and use the front panel adjust knob to adjust the value.

Another way is to activate the Digital trace group by
touching the trace descriptor label once and then using
the front panel channel controls (V/div and Offset) to
adjust the position and size.

You can view a group of digital traces as individual lines (Expand mode),
like this:

MS-500 Mixed Signal Oscilloscope Option

22

922245-00 Rev A

Or collapsed into a bus (Collapse mode), like this:

Just select the appropriate button to get the view that you want.

You can rename the collapsed bus for easier identification
from the oscilloscope grid. For instance, if we were to name
Digital1 as ADDR, it would appear as follows on the grid:

Where ADDR appeared on the far left side of the grid. Very long bus names
can be used, but the longer the name; the more bus data is obscured.

You can store a Digital trace group to memory, or move it to
another grid, just like you would a Channel. These controls
function identically for Channels and Digital trace groups.

Digital Logic Threshold Setup

The threshold level determines how the input signal is interpreted. The
threshold level can be set in either the Digital Setup or Digital Trigger Setup
menus (it is the same setup, but is in two different places for operator
convenience). Input voltages less than the threshold are converted to 0.
Input voltages greater than the threshold are converted to 1.

Operator’s Manual

922245-00 Rev A 23

The threshold levels can be set between -10.0 V and +10.0 V. TTL circuits
use a threshold voltage level of 1.58 V. ECL circuits use a threshold voltage
level of -1.39 V. Other threshold settings are available in the setup dialog.

The minimum high voltage level is user definable by the hysteresis control
up to 1.4 V above the threshold. The maximum low voltage level is user
definable by the hysteresis control up to 1.4 V below the threshold. The
minimum signal swing is 100 mV. The indeterminate range of 50 mV
around the threshold voltage level is the level below which the MS-500 will

not operate. However, the MS-500 can support a signal as low as 100 mV

only if the input signal’s quality is adequate.

The Digital Logic Threshold Setup dialogs are contained in both the Trigger
dialogs and in the Digital Setup dialogs. It is important to note that a
selection made in one location does affect the value in the other. Up to
four different logic levels can be selected: levels can be set for lines D0 to
D8, D9 to D17, D18 to D26 and D27 to D35. When connecting your lines,
make sure that all lines with like levels are connected to the same set of 9
digital lines.

Touch the Logic Setup tab to view the following dialog:

You can select various Logic Families, or select User Defined and define a
custom threshold crossing. Touch inside the Logic Family selection to view
a selection list.

MS-500 Mixed Signal Oscilloscope Option

922245-00 Rev A

If you select User Defined, then you are able to define the voltage level.
Otherwise, the Voltage Level selection is grayed out.

Digital Trigger Setup

When the MS-500 option is loaded onto the oscilloscope, additional trigger
capabilities are added to the normal oscilloscope trigger. These new trigger
capabilities permit you to select digital lines as the sources for your
oscilloscope triggers such as Edge, Width, Glitch, Interval and Dropout.
Other triggers can work as combination triggers incorporating analog and
digital triggering capabilities. These triggers are Qualified (A-B Event
Trigger) and Logic Pattern Trigger.

Operator’s Manual

922245-00 Rev A 25

Creating a Pattern Trigger

There are two different ways to trigger digitally as follows:

Logic – permits creation of a simple or complex
analog/digital cross-pattern trigger condition with a mix of 0,

1, rising edge, falling edge, either edge, or don’t care

conditions on up to 4 analog channels and 18 digital lines.

Logic Bus – permits creation of a digital trigger that
corresponds to a hexadecimal bus value for up to 18 digital
bits.

Filter Out Unstable Conditions – Use this filter to ignore short glitches in
logic state triggers that last less than 3.5ns. If the box is unchecked all logic
states are shown. This filter is enabled by default

Logic Pattern Trigger Setup

The Logic Pattern Trigger dialog, with detail on some of the setup
conditions, is shown in the following images:

Select a value for any of the digital lines by touching the existing value
(using either your finger or a mouse), opening the pop-up menu with a list
of choices, and then selecting one of the choices. Alternatively, you can set

a hex value by byte (or view what the resulting hex value conversion).
Touch the arrow buttons to scroll to the next group of eight digital lines.
Note that you may set a digital line to any value in the Logic trigger setup
even if it is not defined as part of a Digital group.

PLEASE NOTE THE FOLLOWING:

 You may set a digital line to any value in the Logic trigger setup

even if it is not defined as part of a Digital group.

 You can set multiple digital lines to different edge conditions.

However, the edge conditions are always grouped in an OR trigger
condition.

Logic Bus Trigger Setup

The Logic Bus Trigger setup dialog is shown as follows:

The Logic Bus trigger dialog is very similar to the Digital Logic trigger dialog.
The main difference is that you must select a Digital source (Digital1,
Digital2, Digital3, or Digital4). In addition, only those bits that are defined
as part of that Digital group can be defined in the Logic Bus setup dialog. A
hexadecimal data value can be entered directly, or read as a result of the
binary setup.

Operator’s Manual

922245-00 Rev A 27

Digital Logic Threshold Setup

The Digital Logic Threshold Setup dialogs are located on both the Trigger
and Digital Setup dialogs. It is important to note that a selection made in
one location does affect the value in the other. Four different logic levels
can be selected. One level can be set for each of the four groups D0 to D8,
D9 to D17, D18 to D26, and D27 to D35. When connecting your lines, make
sure all lines with like levels are connected to the same set of 9 digital lines

Touch the Logic Setup tab to view the following dialog:

You can select various Logic Families, or select User Defined and define a
custom threshold crossing. Touch inside the Logic Family selection to view
a selection list.

If you select User Defined, voltage level can be defined. Otherwise, the
Voltage Level selection is grayed out.

Characterize Digital or Mixed Signal

System Performance Overview

The oscilloscope contains a number of built-in tools, such as cursors,
measurement parameters, statistics, and optional graphical analysis tools
that allow you to characterize your DUT’s performance. The number and
type of these tools change depending on the Teledyne Leroy oscilloscope
you are using and what other software options are loaded on your
instrument. The tools can be used on the Digital traces and buses just like
they are used on any channel.

You may want to use cursors for making single-shot timing measurements,
and measurement parameters when you need to accumulate statistical
data over many different acquisitions.

Using Cursors

Use horizontal cursors to mark locations on the waveform where the time
measurement should be done, then read the cursor values to establish the
measurement. As necessary, adjust the timebase or create zooms of the
channel(s) and the Digital trace groups to view the signal with enough
detail. This is a good method for single-shot / single measurements.

Operator’s Manual

922245-00 Rev A 29

NOTE : When Horizontal (Time) cursors are ON, the hexadecimal bus values
for each Digital trace group appear on the Digital trace descriptor label.

This can be useful when trying to measure to a specific bus value.

Using Measurement Parameters

Measurement parameters can be used to make basic timing and other
measurements of your digital or mixed-signal system. Basic parameters,
such as Delay, Delta Delay, Frequency, Period, Width, and Duty Cycle (not
all parameters are available in WaveSurfer) can be used with a digital line
as a source.

Delay – Time from the trigger to the first transition at

the 50% crossing

Delta Delay – Time between the 50% crossing of first
transition of two waveforms

Duty Cycle – Percent of time data is above 50%

Frequency – Frequency of every cycle in a waveform

at the 50% level and positive slope

Period – Period of every cycle in a waveform at the
50% level and positive slope

Width – Width measured at the 50% level (can be
positive or negative slope)

922245-00 Rev A

Measurement Gating

Gating is available on each parameter so you can set a measurement
window in which the parameter should be activated. This allows you to
eliminate unwanted portions of the acquisition from your measurement.

Select gating from the Measure dialog by selecting the tab for the
appropriate measurement (P1, P2, etc.) and then setting the start and stop
for the gate. Reference the oscilloscope’s On-Line Help for more
information on how to set gating.

Using Statistics and Graphing

Statistics and Histicons allow you to gather numerical and
visual information on the distribution of your various
measurements.

You can turn on Statistics and Histicons separately in the
Measure dialog. Simply touch the appropriate box to
checkmark it and turn it ON; or touch it again to turn it OFF.

In addition, some optional Teledyne LeCroy
programs add capability to produce larger
histograms and trends of your measurement
parameters. If you have this capability, then you
can access it through the Measurement Parameter setup dialog (the Px

tab)

Isolate and Analyze Signal Activity

The combination of Analog Triggering, Digital Triggering, Analog Capture,
Digital Capture, and normal oscilloscope features is a powerful combination
of tools that can make it very easy to find latent HW or SW problems in
your circuit. The oscilloscope is no longer a tool only for hardware
engineers. Now software engineers can easily visualize the mix of analog
and digital signals and relate it to programming code and operation.

Following are some common mixed signal analysis needs and methods.

Zooming Waveforms

There are a number of ways to zoom a mix of analog and digital signals. The
easiest method is to STOP the acquisition and then simply adjust the
timebase Time/Div and Delay knobs on the front panel.

Use the Time/Div knob to change the zoom ratio, and the Delay knob to
change the position.

NOTE: When you adjust timebase to zoom, the position adjustment is
limited by the maximum pre-trigger and post-trigger delay adjustment
available in your oscilloscope. Reference your oscilloscope manual for
specifications of these delays.

You can also zoom by drawing a box with a mouse pointer around the area
that you wish to zoom. Follow these steps:

MS-500 Mixed Signal Oscilloscope Option

922245-00 Rev A

1. Select the area you wish to zoom by drawing a box around it with a

mouse pointer.

2. A second grid is created of the zoomed traces. Use either the Zoom

control knobs or the Vertical/Horizontal control knobs to adjust
the vertical and horizontal scale and position. Reference your

oscilloscope operator’s manual for more information

Reference your oscilloscope’s On-Line Help or Getting Started Manual for

complete information on zooming.
