Preparing for Use
This chapter gives you instructions for preparing the logic analyzer module for
use.

16
Chapter 2: Preparing for Use
Power Requirements
All power supplies required for operating the logic analyzer are supplied through
the backplane connector in the mainframe.
Operating Environment
The operating environment is listed on page 12. Note the non-condensing
humidity limitation. Condensation within the instrument can cause poor
operation or malfunction. Provide protection against internal condensation.
The logic analyzer module will operate at all specifications within the
temperature and humidity range given on page 12. However, reliability is
enhanced when operating the module within the following ranges:
Temperature: +20°C to +35°C (+68°F to +95°F)
Humidity: 20% to 80% non-condensing
Storage
Store or ship the logic analyzer in environments within the following limits:
• Temperature: -40°C to +75°C (-40°F to +167°F)
• Humidity: Up to 90% at 65°C (+149°F)
• Altitude: Up to 15,300 meters (50,000 feet)
Protect the module from temperature extremes which cause condensation on the
instrument.
To inspect the module
1Inspect the shipping container for damage.
If the shipping container or cushioning material is damaged, keep them until you
have checked the contents of the shipment and checked the instrument
mechanically and electrically.
2Check the supplied accessories.
One or more of the accessories listed on page 10 are required to operate the
16910/11A logic analyzer module.
3Inspect the product for physical damage.
Check the module and the supplied accessories for obvious physical or

17
Chapter 2: Preparing for Use
mechanical defects. If you find any defects, contact your nearest Agilent
Technologies Sales Office. Arrangements for repair or replacement are made, at
Agilent Technologies' option, without waiting for a claim settlement.
To configure and install the module
Instructions for configuring and installing the module into the mainframe can be
found in the installation guide for the mainframe.
If you don’t have the installation guide for your mainframe, you can find the latest
version on the Internet at www.agilent.com.
For example: to find the installation guide for a 16900A-series mainframe, go to
www.agilent.com and enter 16900A installation guide in the quick search box. Then
scroll down to Manuals, Guides & Notifications to find the 16900A-Series Logic
Analysis Systems Installation Guide.
To test the module
The logic analyzer module does not require an operational accuracy calibration or
adjustment. After installing the module, you can test and use the module.
• If you require a test to verify the specifications, see the “Testing Logic Analyzer
Performance” chapter on page 19. If you require a test to verify correct module
operation using software self-tests, see “Do a self-test on the logic analysis system.” on
page 30.
• If the module does not operate correctly, see “Troubleshooting” on page 63.
To clean the module
• With the mainframe turned off and unplugged, use a cloth moistened with a mixture
of mild detergent and water to clean the rear panel.
• Do not attempt to clean the module circuit board.

Testing Logic Analyzer Performance
This chapter tells you how to test the performance of the 16910A or 16911A logic
analyzer against the specifications listed on page 11.

20
Chapter 3: Testing Logic Analyzer Performance
To ensure the 16910A or 16911A logic analyzer (also referred to as the module or
the card) is operating as specified, software tests (self-tests) and a manual
performance test are done. The logic analyzer is considered performance-verified
if all of the software tests and the manual performance test have passed. The
procedures in this chapter indicate what constitutes a “Pass” status for each of
the tests.
Test Strategy
This chapter describes the module being tested in an Agilent Technologies
16900A-series mainframe.
Only specified parameters are tested. Specifications are listed on page 11. The
test conditions defined in this procedure ensure that the specified parameter is
as good as or better than specification. No attempt is made to determine
performance which is better than specification. Not all channels of the logic
analyzer will be tested; rather a sample of channels is tested. The calibration
laboratory may choose to elaborate on these tests and test all channels at their
discretion.
One-card Module. To perform a complete test on a one-card module, start at
the beginning of the chapter and follow each procedure.
Multi-card Module. To perform a complete test on a multi-card module,
perform the self-tests (page 30) with the cards connected. Then, remove the
multi-card module from the mainframe and configure each card as a one-card
module. Install the one-card modules into the mainframe and perform the
performance verification tests on each card. When the tests are complete,
remove the one-card modules, reconfigure them into their original multi-card
module configuration, reinstall it into the mainframe and perform the self-tests
again. These steps are necessary to ensure that the clocks are tested on each
module.
For removal instructions see Chapter 6, “Replacing Assemblies,” beginning on
page 83. For installation and configuration instructions see Chapter 2, “Preparing
for Use,” beginning on page 15.
Test Interval
Test the performance of the module against specifications at two-year intervals.
Test Record Description
A Performance Test Record for recording the results of each procedure is located
at the end of this chapter.
