Chapter 1: General Information
Accessories
One or more of the following accessories, sold separately, are required to operate
the 16753/54/55/56A or 16950A logic analyzer.
Mainframe and Operating System
The 16753/54/55/56A logic analyzers require a 16700-series logic analysis system
with operating system version A.02.70.00 or higher, or any 16900-series logic
analysis system.
The 16950A logic analyzer requires a 16900-series logic analysis system.
To check your 16700-series logic analysis system’s operating system version
number, open the System Administration window, click the Admin tab, then click
About...
If the proper version is not loaded, obtain a copy of the updated operating system
software and install it in the logic analyzer mainframe. You can request a software
upgrade at http://software.cos.agilent.com/16700 or by contacting your nearest
Agilent Technologies Customer Support Center.
Three Cooling Fans Required in 16700A-series Mainframe
Earlier versions of the 16700A/01A/02A mainframe contained only two cooling
fans and might not provide adequate cooling to ensure reliable performance. If
the first six digits of the 16700A/02A serial number (located on the back of the
instrument) are US3849 or higher, or the first six digits of the 16701A are US3902
or higher, the instrument is a three-fan model, which will supply sufficient
cooling.
All 16700B/01B/02B and all 16900-series systems provide adequate cooling to
ensure reliable performance.

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 13. 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 13. 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
16753/54/55/56A or 167950A logic analyzer module.
3Inspect the product for physical damage.
Check the module and the supplied accessories for obvious physical or

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 16700B mainframe, go to
www.agilent.com and enter 16700B installation guide in the quick search box. Then
scroll down to Manuals, Guides & Notifications to find the 16700B-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 “Testing Logic Analyzer
Performance” on page 19. If you require a test to verify correct module operation
using software self-tests, see “Do a self-test on the 16900-series logic analysis system”
on page 38 or “Do a self-test on the 16700-series logic analysis system” on page 62.
• If the module does not operate correctly, see “Troubleshooting” on page 89.
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.
