Compliance
FCC/Canada Radio Frequency Interference Compliance*
Determining FCC Class
The Federal Communications Commission (FCC) has rules to protect wireless
communications from interference. The FCC places digital electronics into two classes.
These classes are known as Class A (for use in industrial-commercial locations only) or
Class B (for use in residential or commercial locations). Depending on where it is
operated, this product could be subject to restrictions in the FCC rules. (In Canada, the
Department of communications (DOC), of Industry Canada, regulates wireless
interference in much the same way.)
Digital electronics emit weak signals during normal operation that can affect radio,
television, or other wireless products. By examining the product you purchased, you can
determine the FCC Class and therefore which of the two FCC/DOC Warnings apply in
the following sections. (Some products may not be labeled at all for FCC; if so, the
reader should then assume these are Class A devices.)
FCC Class A products only display a simple warning statement of one paragraph in
length regarding interference and undesired operation. Most of our products are FCC
Class A. The FCC rules have restrictions regarding the locations where FCC Class A
products can be operated.
FCC Class B products display either a FCC ID code, starting with the letters EXN, or
the FCC Class B compliance mark.
Consult the FCC web site http://www.fcc.gov for more information.
FCC/DOC Warnings
This equipment generates and uses radio frequency energy and, if not installed and
used in strict accordance with the instructions in this manual and the CE Mark
Declaration of Conformity**, may cause interference to radio and television reception.
Classification requirements are the same for the Federal Communications Commission
(FCC) and the Canadian Department of Communications (DOC).
Changes or modifications not expressly approved by AlazarTech Inc. could void the
user’s authority to operate the equipment under the FCC Rules.
Class A
Federal Communications Commission
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
Canadian Department of Communications
This Class A digital apparatus meets all requirements of the Canadian Interference-
Causing Equipment Regulations. Cet appareil numérique de la classe A respecte
toutes les exigences du Règlement sur le matériel brouilleur du Canada.

ATS850 User Manual v
Compliance to EU Directives
Readers in the European Union (EU) must refer to the Manufacturer's Declaration of
Conformity (DoC) for information** pertaining to the CE Mark compliance scheme. The
Manufacturer includes a DoC for most every hardware product except for those bought
for OEMs, if also available from an original manufacturer that also markets in the EU, or
where compliance is not required as for electrically benign apparatus or cables.
To obtain the DoC for this product, click Declaration of Conformity at
http://www.alazartech.com/support/documents.htm. This web page lists all DoCs by
product family. Select the appropriate product to download or read the DoC.
* Certain exemptions may apply in the USA, see FCC Rules §15.103 Exempted
devices, and §15.105(c). Also available in sections of CFR 47.
** The CE Mark Declaration of Conformity will contain important supplementary
information and instructions for the user or installer.
Environmental Compliance
Alazar Technologies Inc., hereby certifies that this product is RoHS compliant, as
defined by Directive 2002/95/EC of the European Parliament and of the Council of 27
January 2003 on the restriction of the use of certain hazardous substances in electrical
and electronic equipment. All manufacturing has been done using RoHS-compliant
components and lead-free soldering.

About Your ATS850
Thank you for your purchase of an ATS850. The ATS850 PCI
based waveform digitizer has the following features:
• Two 8-bit resolution analog input channels
• Half length PCI bus card
• Real-time sampling rate of 50 MS/s to 10 KS/s
• 25 MHz analog input bandwidth
• Analog trigger channel with software-selectable level,
slope, and hysteresis
• Software-selectable AC/DC coupling and 1MΩ/50Ω
input impedance
• 262,140 sample onboard memory, standard
• Pre-trigger and Post-Trigger Capture with Multiple
Record capability
• NIST traceable calibration
• Optional Trigger Out Upgrade for Ultrasonic
Applications
All ATS850 digitizers follow industry-standard Plug and Play
specifications on all platforms and offer seamless integration
with compliant systems. If your application requires more
than two channels for data acquisition, you can synchronize
multiple digitizers on all platforms using a Master/Slave
SyncBoard.
Detailed specifications of the ATS850 digitizers are listed in
Appendix A, Specifications.

ATS850 User Manual 3
Acquiring Data with Your ATS850
You can acquire data either programmatically by writing an
application for your ATS850 or interactively with the
AlazarDSO software.
If you want to integrate the ATS850 in your test and
measurement or embedded OEM application, you can
program the digitizer using C/C++, Visual BASIC or
LabVIEW.
For programming in C/C++ or Visual BASIC, you must
purchase the ATS-SDK software development kit that comes
with sample programs and a reference manual describing the
API.
For programming in LabVIEW, you must purchase the ATS-
VI virtual instrument library that comes with a high-level,
easy-to-use VI that makes integrating the ATS850 into your
own system very simple.

4 ATS850 User Manual
Interactively Controlling your ATS850 with AlazarDSO
The AlazarDSO Soft Front Panel allows you to interactively
control your ATS850 as you would a desktop oscilloscope. To
launch the Scope Soft Front Panel, select
Start » Programs » AlazarTech » AlazarDSO
The following screen will be displayed. If you connect the
input to a signal generator and click on Start button, you
should see the signal on the screen.
AlazarDSO has been designed to be very intuitive and uses
the same user interface as most of today’s digital
oscilloscopes.
• Note that AlazarDSO does not support Windows 98.
If you are using Windows 98SE, you can use the
legacy API Panel software for acquiring signals
interactively.

ATS850 User Manual 5
ATS-SDK API
The ATS-SDK API is used for programming the ATS850 in
C/C++ or Visual BASIC. It provides the exact same API that
is used for writing AlazarDSO software. To help you get
started, ATS-SDK comes with examples you can use or
modify.
ATS-VI LabVIEW VI
ATS-VI allows you to integrate the ATS850 into your own
LabVIEW program. A high level VI is supplied that requires
very few controls to get started.

6 ATS850 User Manual
ATS-Linux
ATS-Linux allows you to integrate the ATS850 into a Linux
application written in C. Linux drivers are provided as a
binary file, whereas all sample programs are supplied in C
source code. Compatible with kernel versions up to and
including 2.6.

ATS850 User Manual 7

ATS850 User Manual 11
Unpacking
Your digitizer is shipped in an antistatic package to prevent
electrostatic damage to the digitizer. Electrostatic discharge
can damage several components on the digitizer. To avoid
such damage in handling the digitizer, take the following
precautions:
• Ground yourself via a grounding strap or by holding a
grounded object.
• Touch the antistatic package to a metal part of your
computer chassis before removing the digitizer from
the package.
• Remove the digitizer from the package and inspect
the digitizer for loose components or any other sign
of damage. Notify AlazarTech if the digitizer appears
damaged in any way. Do not install a damaged
digitizer into your computer.
• Never touch the exposed pins of the connectors.

12 ATS850 User Manual
Installing the ATS850
There are four main steps involved in installation:
1. Physically install the digitizer(s) and SyncBoard, if
any, in your computer
2. Install ATS850 software driver, when prompted
3. Install AlazarDSO software that allows you to setup
the hardware, acquire signals and view and archive
them
4. Optionally, install the ATS-SDK software
development kit or ATS-VI LabVIEW VI, which
enables you to programmatically control the ATS850
The following paragraphs will guide you through this process
in a step-by-step manner.
