Welcome
Thank you for buying a Teledyne LeCroy product. We’re certain you’ll
be pleased with the detailed features unique to our instruments. This
Operator’s Manual covers important safety and installation information
for your SAM40 Sensor Acquisition Module, along with basic operation.
Introducing SAM40 Sensor Acquisition Module
The SAM40 sensor acquisition module simply and quickly interfaces to
a supported Teledyne LeCroy 12-bit high definition oscilloscope (HDO).
The SAM40 acquires very low speed (kHz bandwidth) sensor and other
signals, while the HDO acquires higher speed analog, digital and serial
data signals. The HDO cross-triggers the SAM40, and the SAM40 sends
acquisition data to the HDO for time-synchronized display with the high
bandwidth HDO analog and digital channels.
An HDO with a SAM40 permits fast debug and validation of complex
deeply embedded control systems, mechatronics, and electro-mechanical
systems. An HDO with a sensor acquisition module cost-effectively
replaces multiple instruments with one consolidated view of system
performance. All math, measurements, pass/fail and other analysis
capabilities that can normally be performed on acquired oscilloscope
data can also be performed on the SAM40 acquisition data.
SAM40 data can be easily unitized and rescaled into appropriate sensor
units. More than 65 different SI and English system physical units are
supported for length, mass, temperature, angle, velocity, acceleration,
volume, force/weight, pressure, electrical, magnetic, energy and rotating
machine quantities. Math and measurements applied to rescaled
waveforms correctly read and convert to new units as required.

BASICS
When the oscilloscope is started with a SAM40
Sensor Acquisition Module connected, the
oscilloscope Vertical menu will offer an option for
Sensor Setup. Choose this to open the Sensor
Setup dialog.
Conguring Sensor Input Channels
Similar to the Channel Setup dialog, Sensor Setup is a collection of all the available sensor input channels, allowing you to quickly enable/disable a
channel. Behind it are the individual Sensor (SEn) conguration dialogs. Select "More..." near the closebox to display additional tabs.

SAM40 Operator’s Manual 5
BASICS
The Sensor dialogs contain many of the same settings as the Channel (Cn) conguration dialogs.
4 mA Bias
When the 4 mA Bias checkbox is selected, the SAM40 applies an excitation
current to IEPE/ICP sensor inputs. It is disabled when Coupling is set to
something other than IEPE.
Note: It is recommended to leave the 4 mA Bias checkbox deselected (the
default state) until sensors are connected, then select it prior to taking
measurements.
Bandwidth
The selectable bandwidth settings are Full (40 kHz), 2 kHz, 500 Hz, and
100 Hz. SAM40 inputs utilize a digital IIR lter to limit bandwidth.
Vertical Scale
As with channel traces, the Vertical Scale sets the amount of voltage (or
different vertical unit) represented by one Vertical division of the grid.
Coupling
When the input is an IEPE/ICP-compatible sensor, check <24 Vpk Input
(max. input for IEPE sensors) and select IEPE from the Coupling eld.
Otherwise, for a voltage input, you may leave <24 Vpk Input unchecked
and select DC1MΩ, AC1MΩ, or Ground coupling.
Note: Maximum input voltage is 50 Vpk for DC1MΩ, AC1MΩand Ground
coupling, but only 24 Vpk for IEPE coupling.

928571-00 Rev A

To rescale a sensor trace to a unit other than Volts or Amperes, on the
SEndialog choose Vertical Unit Others, then select the Sensor Setup
button to display the rescale settings:
Unit Category is the unit type, for example, Length or Velocity.
Units reflect the category selection, for example, a Length unit of meters
(m) versus a Velocity unit of meters per second (m/s).
Units/V (slope) is the multiplication factor (a) used to scale the acquired
sensor Voltage. Enter the number of the new unit that will equal 1 Volt.
Add is the amount of additive constant (b) to add to the rescaled value.
This value is always given in the new unit.
Rescaling
Most sensors output voltage values. The SAM40 rescale settings allow
you to change the units in which sensor output values are displayed to
a much wider selection than Volts or Amperes. They can also be used
for intelligent rescaling of output values, equivalent to using the Rescale
math function (y=ax+b), where:
• a is the multiplication factor (Units/V)
• b is the additive constant (Add)
Tip: Analog channels, parameters, and math functions can be rescaled
to many of the same units as sensors by using the Units subdialog next
to the main setup dialogs For instructions, see your oscilloscope online
Support or Operator's Manual.
As with channel rescaling, measurements performed on this sensor are
converted and displayed in the selected unit. However, math functions
are displayed in the unit that is logically appropriate for the result,
including complex results that must be derived from a table of core
SI units.
Units are automatically rescaled up or down within the list of SI unit
prefixes based on the relative size of the input signal.
BASICS
Example: Multiplying one sensor trace in Volts per meter by another
sensor trace in meters yields a result in Volts.
Example: 1000 V is displayed as 1 kV, while .1 V is displayed
as 100 mV. When the rescale value is 1 V = 1 Pascal (Pa), a 1
milliVolt (mV) reading is displayed as 1 mPa rather than .001 Pa
or 100e-3 Pa.

SAM40 Operator’s Manual 7
Sensor signals with unit conversion. The math function applied to these signals (F7) is automatically shown in the
logically appropriate unit for the product of Amperes and Volts—Watts.
The Units subdialog offers a selection
of alternative units in the equivalent
dimension to Watts for the F7 trace.
BASICS
For math functions and measurements parameters, a further unit override is possible on the Units subdialog, which shows a selection of units in the
equivalent dimension to the unit of the Fnor Pnsource trace. For example, while the default unit for the product of Volts and Amperes would be Watts, a
user could choose to instead display this function as Volt-Amperes Reactive (VAR) or horsepower (hp).

928571-00 Rev A

BASICS
Further rescaling and changing units of one of the sensor traces
to Coulombs produces another automatic rescaling and unit
conversion for the math trace F7—this time to Joules.
Another math function (F12) applied to math trace F7 once again
yields the appropriate unit for the derivative of Joules, Watts.

SAM40 Operator’s Manual 9
BASICS
Units of Measure
Channel and sensor traces may be displayed in the following units. Use the notation in the Code column when specifying these units in remote control
programs and customization scripts.
Note: Use only the base unit in code. The system automatically calculates prefixes based on the operation, timebase, and relative size of the input
signals. Some additional units are available for math functions and measurement parameters; these are shown on the respective Units subdialog.

MAINTENANCE
Sample Rate
The far right of the Timebase dialog shows the rate at which the SAM40
is sampling.
When the oscilloscope is sampling at a fixed rate, the SAM40 will sample
at a maximum rate of 100 kS/s so long as the oscilloscope Sample Rate
and Time/div settings allow it.
When the oscilloscope is set to Max Memory mode, increasing the
Time/div will decrease the SAM40 sample rate below 100 kS/s once the
Time/div requires it.
Regardless of the SAM40 sample rate, the timebase is locked to the
oscilloscope, and sensor traces will always be time synchronous with
channel traces.
Maintenance
Cleaning
Clean the outside of the SAM40 using a soft cloth moistened with water
or isopropyl alcohol solution. Do not use harsh or abrasive cleansers. Dry
thoroughly before using. Do not submerge the instrument or allow mois-
ture to penetrate it.
Calibration
Schedule factory calibration once per year. Contact your local Teledyne
LeCroy office for service.
Firmware Updates
The SAM40 requires the matched version of MAUI firmware (XStreamDSO).
You will not be able to install the SAM40 firmware unless the correct
version of MAUI is present on the oscilloscope; likewise, if you update
MAUI, you must also update the SAM40. Firmware can be found at
teledynelecroy.com/support/softwaredownload under Oscilloscope
Downloads > Firmware Updates. Register on our website for notices of
periodic firmware updates.
1. Download SAM_Installer.exe onto a portable USB drive or directly to the
oscilloscope desktop if it has an internet connection.
2. Select File > Exit to close the oscilloscope application.
3. With the SAM40 connected to the oscilloscope and powered on, use
Windows Explorer to navigate to and launch SAM_Installer.exe. Connect
portable drives to any oscilloscope host USB port.
4. Follow the installer prompts, accepting all installed software and
license agreements.
5. When finished, power cycle the SAM40 and the oscilloscope.
