2.0 Maintenance
Before performing any maintenance, follow the safety
information in the ETS-Lindgren Product Information Bulletin
included with your shipment.
Maintenance is limited to the components as described in
this manual. If you have any questions concerning
maintenance, contact ETS-Lindgren Customer Service.
Periodic maintenance will ensure the continued performance of the Gigahertz
Transverse Electromagnetic (GTEM!™) Cell. Several areas must be considered,
as described in the following sections.
Performance Monitoring
On-site VSWR measurements are normally performed at the conclusion of
installation procedures for the GTEM!. They are also performed at the factory for
all factory-assembled GTEM! cells. If the GTEM! is to be installed by an
ETS-Lindgren representative, then the on-site VSWR measurement is the
responsibility of the representative. Determination of continued performance to
specified parameters may be ensured by periodic re-measurement of the VSWR.
This could detect changes in performance parameters that would signal
unacceptable performance. The VSWR measurement should be performed on a
schedule as recommended by the customer’s Quality Engineering. The default
time period between such evaluations (this is not a calibration) is six months.
