Operator’s Manual
Welcome
Thank you for purchasing a Teledyne LeCroy ArbStudio.
ArbStudio is a series of high performance Arbitrary Waveform Generators (AWG) consisting of 2 and 4 channel models, 2 Mpts/ch memory, 16 bit resolution and a maximum sample rate of 1 GS/s. Some models provide the ability to generate 18 or 36 channel digital patterns and all models can be operated in true arbitrary mode or Direct Digital Synthesis (DDS) mode.
We truly hope these materials provide increased comprehension when using Teledyne LeCroy's fine products.
Sincerely,
David C. Graef
Teledyne LeCroy Corporation

Safety Instructions
This section contains instructions that must be observed to keep the instrument operating in a correct and safe condition. You are required to follow generally accepted safety procedures in addition to the precautions specified in this section. The overall safety of any system incorporating this instrument is the responsibility of the assembler of the system.
Symbols
These symbols appear on the instrument's front or rear panels and in its documentation to alert you to important safety considerations.
CAUTION of damage to instrument, or WARNING of hazard to health. Attend to the accompanying information to protect against personal injury or damage. Do not proceed until conditions are fully understood and met.
WARNING. Risk of electro-shock.
Measurement ground connection.
Safety (protective) ground connection.
Alternating Current.
Precautions
Use proper power cord. Use only the power cord shipped with this instrument and certified for the country of use.
Maintain ground. This product is grounded through the power cord grounding conductor. To avoid electric shock, connect the external AC adapter only to a grounded mating outlet.
Connect and disconnect properly. Do not connect/disconnect probes or test leads while they are connected to a voltage source.
922244-00 Rev A |

ArbStudio
Observe all terminal ratings. Do not apply a voltage to any input that exceeds the maximum rating of that input. Refer to the front of the instrument for maximum input ratings.
Use only within operational environment listed. Do not use in wet or explosive atmospheres.
Use indoors only.
Keep product surfaces clean and dry.
Do not block the cooling vents. Leave a minimum six-inch (15 cm) gap between the instrument and the nearest object. Keep the underside clear of papers and other objects.
Do not remove the covers or inside parts. Refer all maintenance to qualified service personnel.
Do not operate with suspected failures. Do not use the product if any part is damaged. Obviously incorrect measurement behaviors (such as failure to calibrate) might indicate impairment due to hazardous live electrical quantities. Cease operation immediately and sequester the instrument from inadvertent use.
Operating Environment
The instrument is intended for indoor use and should be operated in a clean, dry environment. Before using this product, ensure that its operating environment is maintained within these parameters:
Temperature: 0 °C to 50 °C
NOTE: Power Supply Adapter for ArbStudio 1104 is rated for 40 °C max.
Humidity: Maximum relative humidity 80% (non-condensing) for temperatures up to 40 °C decreasing linearly to 50 % relative humidity at 50 °C.
Altitude: Up to 10,000 ft (3,048 m) at or below 30 °C.

922244-00 Rev A |
Operator’s Manual
Cooling
The instrument relies on forced air cooling with internal fans and vents. Take care to avoid restricting the airflow to any part of the instrument. Around the sides and rear, leave a minimum of 15 cm (6 inches) between the instrument and the nearest object. At the bottom, the instrument feet (up or down) provide adequate clearance.
CAUTION. Do not block instrument vents. Always keep the area beneath the instrument clear of paper and other items.
The instrument also has internal fan control circuitry that regulates the fan speed based on the ambient temperature. This is performed automatically after start-up.
Cleaning
Clean only the exterior of the instrument using a damp, soft cloth. Do not use harsh chemicals or abrasive elements. Under no circumstances submerge the instrument or allow moisture to penetrate it. Avoid electric shock by unplugging the power cord from the AC outlet before cleaning.
CAUTION. Do not attempt to clean internal parts. Refer to qualified service personnel.
Calibration
The recommended calibration interval is one year. Calibration should be performed by qualified personnel only.
CAUTION. It is required that all inputs be removed from the instrument prior to performing a manual calibration.
Schedule an annual factory calibration as part of your regular maintenance. Extended warranty, calibration, and upgrade plans are available for purchase. Contact your Teledyne LeCroy sales representative or customersupport@teledynelecroy.com to purchase a service plan.

Numbered callouts on this image correspond with the following descriptions.
1.POWER - The power switch.
2.DC IN - 12 V – 2.5 A DC connector.
3.USB - USB 2.0 connector.
4.EXPANSION BUS - The Expansion bus connector is located on the rear panel of the ArbStudio 1104 and 1104D models only. Using the appropriate expansion cable, up to 8 total 4 Channel ArbStudio units may be connected.
It is possible to have a system with up to 8 independent arbitrary waveform generators, each with the ability to have a synchronized trigger.
PLEASE NOTE THE FOLLOWING:
ArbStudio 1104 and 1104D units sharing the Expansion bus must all be connected to the same controller (PC) via USB or hub.
If more than one ArbStudio 1104 or 1104D are connected to the same PC, they must also be linked through the Expansion bus.
Making Expansion Bus Connections
In order to connect several ArbStudio 1104 or 1104D units you must first:
Connect the ArbStudio units using the Expansion bus.
Connect all ArbStudio units to a single PC by using an USB connector or by using a HUB.
Ensure all ArbStudio units are correctly recognized by the operating system.

Operator’s Manual
When you launch the ArbStudio software, if all the correct connections are made, the instruments are shown as connected together. The interconnected instruments make up your complete ArbStudio system.
Removing Expansion Bus Connections
Before disconnecting or switching off the instrument, it must be removed by left clicking the Safely Remove Hardware icon showing in the Windows System Tray on your PC.
When your operating system eventually shows a Safely Remove Hardware screen, select Safely remove Teledyne LeCroy ArbStudio, and then click the Stop button.
NOTE: If the instrument is switched off or disconnected without performing the proper safe removal process, the software may not operate correctly.

Getting Started with ArbStudio
Overview
This Getting Started section begins by providing essential installation instructions for Drivers and Software. Then, the initial software interfaces are introduced. Finally, Setup Examples and Common Tasks are provided to bring you up to speed as fast as possible.
The How do I section of the ArbStudio Welcome screen contains links to step-by-step explanations of standard functions and setups using your new product.
These titles along with others provided here and in other locations of this documentation provide accurate descriptions for regular tasks.
Software and Driver Installation
Insert the installation CD into your CD/DVD reader on your computer.
If the Welcome screen is not automatically shown, run the cdstart.exe file on the root directory of the installation files.

922244-00 Rev A |
Operator’s Manual
The one installer guides you through proper setup of both the ArbStudio software and necessary drivers for your computer as explained in the following topics.
Software Installation
NOTE: The Microsoft .NET Framework 2.0 Run-Time Engine (or greater) is required to run the ArbStudio 1102/1104 software properly.
After inserting the installation CD into your CD/DVD reader, the Welcome screen is eventually shown, click Install Teledyne LeCroy ArbStudio to start setting up the software.
The ArbStudio Setup Wizard is then shown. Click Next to proceed with the installation.
You can leave the default Installation Folder path, or specify a new location and click Next.
