1 Safety Instructions for LISNs
Products from the Rohde & Schwarz group of companies are manufactured
according to the highest technical standards. To use the products safely, follow
the instructions provided here and in the product documentation. Keep the prod-
uct documentation nearby and offer it to other users.
Use the LISN only for its intended use and within its performance limits. Intended
use and limits are described in the product documentation such as the data
sheet, manuals and the safety instructions brochure. If you are unsure about the
appropriate use, contact Rohde & Schwarz customer service.
Line impedance stabilization networks (LISNs) are designed according to CISPR
16-1-2 (EN 55016-1-2) and do not meet the permissible limit for the leakage cur-
rent as defined in EN 61010-1. In addition, LISNs do not provide basic insulation,
rated as measurement category II (protection class 1). Therefore, only electrically
skilled people may connect, set up and use LISNs.
LISNs can thus pose hazardous and even life-threatening risks.
●Electrical shock because of a high leakage current and live parts if the LISN is
not grounded.
●Electrical shock because the LISN does not have a fuse in the measuring cir-
cuit.
●Burns and fire hazard caused by overheating of the housing. Overheating can
occur if the ventilation is insufficient or if the cables' cross-section is too small.
These users also need sound knowledge of at least one of the languages in
which the user interfaces and the product documentation are available.
If any part of the LISN is damaged or broken, stop using the LISN. Never open
the casing of the LISN. Only service personnel authorized by Rohde & Schwarz
are allowed to repair the LISN. Contact Rohde & Schwarz customer service at
