Troubleshooting

This section provides troubleshooting information for the Agilent Technologies 9000 Series

oscilloscopes. The service strategy of this oscilloscope is replacement of defective assemblies.

Safety

Read the Safety Notices at the back 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, moving parts, fire and electric shock). Lack of training and awareness of the hazards 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.

WARNING INJURY CAN RESULT!

Use caution when working around the cooling fans with the cover removed from the oscilloscope. The

cooling fan blades are exposed on one side and can be hazardous. If the procedure allows, replace the

cover over the chassis (without screwing it back in place) before turning the oscilloscope on. If the

procedure requires you to have the cover off, be careful not to contact these fan blades with any part of

your body.

Tools Required

You will need basic electronic troubleshooting tools, including a digital multimeter and a 100

MHz (or faster) oscilloscope.

If you need to remove and replace assemblies, see chapter 6, “Replacing 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.”
