Maintenance
To prevent electrical shock, disconnect the analyzer from the mains
source before cleaning. Use a dry cloth or one slightly dampened
with water to clean the external case parts. Do not attempt to clean
internally.

Physical Maintenance

Clean the cabinet, including the front panel, using a dry or slightly damp cloth
only.

Caring for Waveguide (WG) Interfaces

A clean surface at millimeter-wave frequencies is much more important than at
lower frequencies because any debris on the waveguide surface can potentially
distort the measurement results.
Caring for WG interfaces is not difficult. Dirt and dust can be removed using
the following:
— Isopropyl alcohol 99.5%
— Lint-free cloth
— Pressurized air (for dust removal)
To remove dirt on the waveguide surface, simply put a few drops of isopropyl
alcohol on a lint-free cloth and gently wipe the surface.
To remove dust, simply spray the pressurized air on the waveguide surface.

Principles of Connector Care

Proper connector care and connection techniques are critical for accurate and
repeatable measurements. Refer to
connector care.
Prior to making connections to your analyzer, carefully review the information
about inspecting, cleaning, and gaging connectors. Refer to the calibration kit
documentation for detailed connector care information.

ture to evaporate, and the fumes to dissipate, prior to assembling waveguide inter-
faces.
