Troubleshooting
Service Strategy
The service strategy for troubleshooting Infiniium V-Series oscilloscopes is to
isolate problems to a faulty assembly, then use the disassembly and assembly
procedures in Chapter 5 , “Replacing Assemblies", to replace the defective
assembly.
Read the Safety booklet that came with the oscilloscope before servicing the
oscilloscope. Before performing any procedure, review it for any cautions and
warnings.
The only equipment you need for troubleshooting to the assembly level is basic
electronic troubleshooting tools such as a digital multimeter. If you need to
remove and replace any assemblies, refer to Chapter 5 , “Replacing Assemblies".
A default setup is provided to return the oscilloscope to a known state. You can
use the default setup to undo previous setups so they do not interfere with the
current measurement. Use the default setup when a procedure requires it by
pressing [Default Setup] on the front panel.
WARNING
INJURY CAN RESULT! Use caution when the oscilloscope fan blades are exposed as
they can cause injury.
CAUTION
AVOID ESD DAMAGE TO COMPONENTS! Electrostatic discharge (ESD) can damage
electronic components. Use proper ESD precautions when doing any of the
procedures in this chapter. Failure to follow proper ESD procedures may cause
immediate failure or latent damage. Latent damage may result in equipment failure
after a period of time. As a minimum, place the oscilloscope on a properly grounded
ESD mat and wear a properly grounded ESD strap.
WARNING
SHOCK HAZARD! Maintenance should be performed by trained service personnel.
Lack of training and awareness could result in electrical shock or other injury. When
maintenance can be performed without power applied, the power cord should be
removed from the oscilloscope.
