Introduction
Strategy for servicing
This manual contains information that is needed to properly service the arbitrary
function generator as well as general information that is critical to safe and
effective servicing.
To prevent personal injury or damage to the arbitrary function generator, consider
the following before attempting service:
The procedures in this manual should be performed only by a qualified service
person.
Read the General safety summary and the Service safety summary.(See
page v.)
Read th e operating requirements for the instrument. (See page 8, Installation.)
When using this manual for servicing, be sure to follow all of the warnings,
cautions, and notes.
This manual contains the information needed for periodic maintenance of the
arbitrary function generator. Further, it contains information for corrective
maintenance down to the module level:
To isolate a failure to a module, use the troubleshooting procedures found
in the Maintenance section.
Toremoveandreplaceanyfailedmodule, follow the instructions in the
Removal and Installation Procedures subsection.
After isolating a faulty module, replace it with a fully-tested module obtained
from the factory. The Replaceable Parts List section contains part number

Floating ground
Operating basics
Since the common input and output channels of the a rbitrary/function generator
are electrically isolated from the chassis ground (the instrument chassis and
ground line of the AC connector), you can make a floating connection between
the instrument and other equipment.
All the BNC connectors are connected to the common ground, and the remote
interface connector is connected to the chassis ground.
CAUTION. T
ground is 42 Vp-p (DC + peak AC). When the potential voltage between the
chassis ground and common ground goes over 42 Vp-p, the internal protective
circuit will be activated to protect the circuits. However, higher voltage may cause
the internal circuits in the instrument to be d amaged.
When a potential voltage exists between the chassis ground and common ground,
a short circuit from output to ground causes the instrument internal fuse to open
and the output is stopped. If the fuse opens, you need to contact your local
