Maintenance
To prevent electrical shock, remove the chassis and VDI modules from
the mains source before cleaning. If an analyzer module needs cleaning,
remove it from the chassis slot. 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 system components using a dry or slightly damp cloth only.
Electrical Maintenance
The M9005A, M9374A, M98xx, and P5000A Series products can be serviced as individual
products. The VDI Calibration Kit and VDI Extenders require servicing by Virginia Diodes,
Inc., and are returned to the factory by Keysight Service Centers for any service.
Vector Network Analyzers can be calibrated.
No calibration is needed for the N5252AW12, but can be operator checked.
No calibration is needed for the N5262AC12, but the cal kit components can be
mechanically verified. Upon first calibration, it is recommended to store the performance
data of your kit's shorts, loads, QW (quarter-wave) shims, and section to compare with if
performance is in question.
The E-Band system is calibrated by the customer using the N5262AC12 Calibration Kit that
comes with the system. A functional certificate is provided with N5252A only. N5253E is
not configured at the factory and does not have a functional certificate.
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%
1
•
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.
1. 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.
