5.2 Electrical Maintenance
The R&S UPZ usually does not require any electrical maintenance. To ensure correct
operation in compliance with data sheet specifications over a long time, it is
recommended to have the specifications checked in a Rohde & Schwarz agency at
intervals of 3 years. This concerns in particular the insertion loss, which may increase
in the course of time due to aging of relays caused by switching or as a result of the
corrosion of the XLR contacts in an aggressive environment.
It is recommended to check the specifications according to the performance test
described in chapter 1 of Service Manual.
The address of our support center and a list of all Rohde & Schwarz service centers
can be found at the beginning of this manual.
5.3 Storage and Packaging
The storage temperature range of the instrument is given in the data sheet. If the
instrument is to be stored for a longer period of time, it must be protected against dust.
Repack the instrument as it was originally packed when transporting or shipping. The
two protective foam plastic parts prevent the control elements and connectors from
being damaged. The antistatic packing foil avoids any undesired electrostatic charging
to occur.
If you do not use the original packaging, use a sturdy cardboard box of suitable size
and provide for sufficient padding to prevent the instrument from slipping inside the
package. Wrap antistatic packing foil around the instrument to protect it from
electrostatic charging.
