Replacing Assemblies
This chapter contains the instructions for removing and replacing the assemblies of
the logic analysis system. Also in this chapter are instructions for returning
assemblies.
WARNING
Hazardous voltages exist on the power supply, the CRT, and the CRT driver board. To avoid
electrical shock, disconnect the power from the instrument before performing the following
procedures. After disconnecting the power, wait at least six minutes for the capacitors on
the power supply board and the CRT driver board to discharge before servicing the
instrument. If the AC LED on the power supply has any illumination, a significant charge
remains on the power supply capacitors.
CAUTION
Damage can occur to electronic components if you remove or replace assemblies when the
instrument is on or when the power cable is connected. Never attempt to remove or install
any assembly with the instrument on or with the power cable connected.
Replacement Strategy
These replacement procedures are organized as if disassembling the complete
instrument, from the first assembly to be removed to the last. Some procedures say
to remove other assemblies of the instrument, but do not give complete instructions.
Refer to the procedure for that specific assembly for the instructions.
CAUTION
Electrostatic discharge can damage electronic components. Use grounded wriststraps and
mats when performing any service to this logic analyzer.
