Troubleshooting

This section provides troubleshooting information for the Agilent Technologies 90000

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.

Default Setup

A Default Setup is provided to return the oscilloscope to a known state. The default

setup can be used to undo previous setups so that they do not interfere with the current

measurement. Use the default setup when a procedure requires it.

• Press the Default Setup key on the front panel to set the oscilloscope to the default state.
