7000 Series Oscilloscopes Service Guide
The service policy for the Agilent 7000 Series oscilloscopes
is assembly level replacement. If you need parts or
assistance from Agilent Technologies to repair your
instrument, go to www.agilent.com and locate the service
facility for your area.
HAZARDOUS VOLTAGES EXIST — REMOVE POWER FIRST !
The procedures described in this section are 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 procedures.
Whenever possible, perform the procedures with the power cord removed from the
oscilloscope. Read the safety notice at the back of this book before proceeding.
HAZARDOUS VOLTAGES EXIST — HIGH VOLTAGE IS PRESENT ON POWER
SUPPLY HEAT SINKS !
The power supply heat sinks of the 7000 Series oscilloscopes are at a high
potential. This presents an electric shock hazard. Protect yourself from electric
shock by keeping this area covered or by not coming in contact with the heat sinks
when the power cord is attached to the oscilloscope!
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.
