Troubleshooting the Oscilloscope

The service policy for the 54621A/22A/24A Oscilloscopes and the 54621D/22D Mixed-Signal Oscilloscopes is instrument replacement. Please call (877) 447-7278 to return the defective instrument, and Agilent Technologies will expedite a refurbished instrument to you under the Agilent Express Exchange program.

HAZARDOUS VOLTAGES EXIST — REMOVE POWER FIRST !

The maintenance described in this section is performed with power supplied to the oscilloscope and with the protective covers removed. Only trained service personnel who are aware of the hazards involved should perform the maintenance. Whenever possible, perform the procedures with the power cord removed from the oscilloscope. Read the safety summary at the back of this book before proceeding.

REMOVE POWER TO AVOID DAMAGE !

Do not disconnect any cables or remove any assemblies while power is applied to the oscilloscope, or damage to the oscilloscope can occur.

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. As a minimum, place the oscilloscope on a properly grounded ESD mat and wear a properly grounded ESD strap.
