Chapter 5: Troubleshooting
The troubleshooting consists of flowcharts, self-test instructions, a cable test, and
a test for the auxiliary power supplied by the probe cable.
If you suspect a problem, start at the top of the first flowchart. During the
troubleshooting instructions, the flowcharts will direct you to perform the self-
tests or the cable test.
The service strategy for this instrument is the replacement of defective
assemblies. This module can be returned to Agilent Technologies for all service
work, including troubleshooting. Contact your nearest Agilent Technologies Sales
Office for more details.
CAUTION: Electrostatic discharge can damage electronic components. Use grounded wrist-straps
and mats when you perform any service to this instrument or to the cards in it.
To use the flowcharts
Flowcharts are the primary tool used to isolate defective assemblies. The flowcharts refer
to other tests to help isolate the trouble. The circled numbers on the charts indicate
connections with the other flowcharts. Start your troubleshooting at the top of the first
flowchart.
Mainframe Operating System
Before starting the troubleshooting on an 16740/41/42A, ensure that the required version
of Agilent Technologies 16700A-series mainframe operating system is installed on the
mainframe. The required operating system software versions are listed in “Mainframe and
Operating System” on page 10. To check the 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.
