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.
Use isopropyl alcohol only in a well-ventilated area. Allow all residual alcohol moisture to evaporate, and

the fumes to dissipate, prior to assembling waveguide interfaces.
