AWG710 Service Manual
Inspection and Cleaning
Inspection and Cleaning describes how to inspect for dirt and damage. It also
describes how to clean the exterior and interior of the AWG710 Arbitrary
Waveform Generators. Inspection and cleaning are done as preventive mainte-
nance. Preventive maintenance, when done regularly, may prevent waveform
generator malfunctions and enhance its reliability.
Preventive maintenance consists of visually inspecting and cleaning the
waveform generator and using general care when operating it.
How often you perform preventive maintenance depends on the severity of the
environment in which the waveform generator is used. It is recommended that
you perform preventive maintenance just prior to doing the generator adjustment.
The cabinet helps keep dust out of the waveform generator and should normally
be in place when operating the generator. The generator’s front cover protects the
front panel and display from dust and damage. Install the front cover when
storing or transporting the generator.
Inspect and clean the waveform generator as often as operating conditions
require. The collection of dirt on components inside can cause them to overheat
and breakdown. (Dirt acts as an insulating blanket, preventing efficient heat
dissipation.) Dirt also provides an electrical conduction path
that could cause an
generator failure, especially under high-humidity conditions.
CAUTION. Avoid the use of chemical cleaning agents which can damage plastics
used in this waveform generator. Use only deionized water when cleaning the
menu buttons or front panel buttons. Use an ethyl alcohol solution as a cleaner
and rinse with deionized water. Before using any other type of cleaner, consult
your Tektronix Service Center or representative.
