Troubleshooting
This section provides troubleshooting information for the Agilent Technologies
8000 Series oscilloscope. The service strategy of this oscilloscope is replacement of
defective assemblies.
Safety
Read the Safety Summary at the front of this manual before servicing the oscilloscope.
Before performing any procedure, review it for cautions and warnings.
WARNING SHOCK HAZARD!
Maintenance should be performed by trained service personnel aware of the hazards involved
(for example, fire and electric shock). Lack of training and awareness of the hazards could result
in electrical shock. When maintenance can be performed without power applied, the power cord
should be removed from the oscilloscope.
WARNING MOVING PARTS HAZARD!
Use caution when working around the cooling fans when the cover has been removed from the
oscilloscope. The cooling fan blades are exposed on one side and can be hazardous. Install the
optional fan safety shield (Agilent Technologies P/N 54810-00601) to protect your fingers from
the fan blades.
Tools Required
You will need basic electronic troubleshooting tools, including a digital multimeter and
a 100-MHz (or faster) oscilloscope.
See Chapter 6, “Replacing Assemblies,” if you need to remove and replace assemblies.
ESD Precautions
When using any of the procedures in this chapter, you must use proper ESD precautions
to protect the oscilloscope components from ESD damage. Failure to follow proper ESD
control procedures may cause immediate failure or latent damage. Latent damage may
result in equipment failure after a period of time. As a minimum, you should place the
oscilloscope on a properly grounded ESD mat and wear a properly grounded ESD wrist
strap when working on the oscilloscope.
Keystroke Conventions
To guide you while setting up the oscilloscope, the following conventions are used to
represent keystrokes and other interactions with the oscilloscope:
• When you need to issue a command through the graphical interface, the command
will be phrased like this: “Select <command> from the <menu name> menu.”
• When you need to select an object on the graphical interface, the instructions will be
phrased something like this: “Select the OK button.”
• When you need to press a key, the instructions will be phrased something like this:
“Press the Run key.”
