4 Maintenance
The ISN including the accessories does not require special maintenance. Users need
only take care to keep the equipment clean and protect the components against
mechanical damage. The connectors, especially the modular components, have only a
limited number of insertion/withdrawal cycles. If the connectors show signs of wear,
you should have Rohde & Schwarz Service replace the connectors. Since replacement
may require a general adjustment of the network, you should always send the
complete ISN to the service department.
Users are not permitted to modify the ISN or its accessories. It is recommended to
have the instrument calibrated once a year.
Clean the instrument housing using a dry cloth. For heavy dirt, use a damp cloth with a
mild, non-abrasive household cleanser if necessary. Do not let liquid enter the housing
of the ISN or the adapters. No chemicals may be used for cleaning purposes.
