1 Safety and regulatory information
The product documentation helps you use the product safely and efficiently. Fol-
low the instructions provided here and in the following chapters.
Intended use
The R&S TSMExxDC instruments are intended to upgrade the R&S TSMx6 scan-
ners to measure 5G NR signals in the mmWave frequency range. The down-
converters extend the latest generation mobile network scanner family and pro-
vide all features for drive and walk testing.
Observe the operating conditions and performance limits stated in the data sheet.
Where do I find safety information?
Safety information is part of the product documentation. It warns you of potential
dangers and gives instructions on how to prevent personal injury or damage
caused by dangerous situations. Safety information is provided as follows:
●In Chapter 1.1, "Safety instructions", on page 5. The same information is
provided in many languages as printed "Safety Instructions". The printed
"Safety Instructions" are delivered with the product.
●Throughout the documentation, safety instructions are provided when you
need to take care during setup or operation.
1.1 Safety instructions
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 product only for its intended use and within its performance limits. Inten-
ded use and limits are described in the product documentation such as the data
sheet, manuals and the printed "Safety Instructions". If you are unsure about the
appropriate use, contact Rohde & Schwarz customer service.
Using the product requires specialists or specially trained personnel. These users
also need sound knowledge of at least one of the languages in which the user
interfaces and the product documentation are available.

Never open the casing of the product. Only service personnel authorized by
Rohde & Schwarz are allowed to repair the product. If any part of the product is
damaged or broken, stop using the product. Contact Rohde & Schwarz customer
service at http://www.customersupport.rohde-schwarz.com.
Operating the product
The product is intended for mobile use. The maximum weight of the product is
provided in the data sheet. If the product casing is not waterproof, use an ade-
quate weather protection to carry the product outdoors with you.
When using the product in a vehicle or aircraft, make sure that the product is
properly secured. If stacking is possible, secure the whole stack of products so
that they cannot fall over and cause injury.
Observe the ambient conditions such as altitude, operating temperature and cli-
matic loads; see the data sheet.
Due to their exposed location, mobile communications systems are at risk of
damage from lightning. This also poses a risk to persons nearby. Vehicles carry-
ing mobile communications systems require an electrically conductive body, a
grounded antenna and also equipotential bonding that includes the cables routed
into the vehicle.
Connecting to power
The product runs on DC voltage. For the specifications of the supply voltage for
the product, refer to the data sheet. Under normal conditions, contact with DC
voltage in this range poses a low risk of electric shock.
Take the following measures for your safety:
●If you connect the product to an external power supply, use one recommen-
ded in the product documentation.
●If you connect the product to a battery, observe the safety information deliv-
ered with the battery.
●Before switching on the product, ensure that the voltage and frequency indica-
ted on the product match the available power source.
●Only use intact cables and route them carefully so that they cannot be dam-
aged. Also ensure that nobody can trip over loose cables.
Meaning of safety labels
Safety labels on the product warn against potential hazards.

3. Insert the AC power plug into a power outlet with ground contact.
3.3 Connecting to RF In
To connect RF cable (SMA connector)
► Connect the RF cable with SMA plug to the RF In (≤ 6 GHz, bypass). See
Figure 4-2 and Figure 4-3.
The SMA connector is sensitive to mechanical stress. Use the following
handling precautions.
●Always use a torque wrench and mount the cable end with 60 Ncm.
●Do not stack adapters directly at the SMA connector. If you need to use
adapters, then always use a specific adapter cable (order no.
4900.1700.00).
To connect RF cable (K connector)
►NOTICE! Using cables with SMA plugs may damage the K connector (bad RF
transition from plug to connector).
Connect the RF cable with K plug to the following RF in connectors.
● Use only cables with K plugs for the connection to the K connector.
● Use the port saver (R&S TDC292JACK, order no. 3637.8397.02) for the K
connector.
