Basic safety instructions
1. The product may be operated only under
the operating conditions and in the
positions specified by the manufacturer. Its
ventilation must not be obstructed during
operation. Unless otherwise specified, the
following requirements apply to
Rohde & Schwarz products:
prescribed operating position is always with
the housing floor facing down, IP protection
2X, pollution severity 2, overvoltage
category 2, use only in enclosed spaces,
max. operation altitude max. 2000 m.
Unless specified otherwise in the data
sheet, a tolerance of ±10% shall apply to
the nominal voltage and of ±5% to the
nominal frequency.
2. Applicable local or national safety
regulations and rules for the prevention of
accidents must be observed in all work
performed. The product may be opened
only by authorized, specially trained
personnel. Prior to performing any work on
the product or opening the product, the
product must be disconnected from the
supply network. Any adjustments,
replacements of parts, maintenance or
repair must be carried out only by technical
personnel authorized by Rohde & Schwarz.
Only original parts may be used for
replacing parts relevant to safety (e.g.
power switches, power transformers,
fuses). A safety test must always be
performed after parts relevant to safety
have been replaced (visual inspection, PE
conductor test, insulation resistance
measurement, leakage current
measurement, functional test).
3. As with all industrially manufactured goods,
the use of substances that induce an
allergic reaction (allergens, e.g. nickel)
such as aluminum cannot be generally
excluded. If you develop an allergic
reaction (such as a skin rash, frequent
sneezing, red eyes or respiratory
difficulties), consult a physician immediately
to determine the cause.
1171.0000.42-02.00 Sheet 2
Safety Instructions
4. If products/components are mechanically
and/or thermically processed in a manner
that goes beyond their intended use,
hazardous substances (heavy-metal dust
such as lead, beryllium, nickel) may be
released. For this reason, the product may
only be disassembled, e.g. for disposal
purposes, by specially trained personnel.
Improper disassembly may be hazardous to
your health. National waste disposal
regulations must be observed.
5. If handling the product yields hazardous
substances or fuels that must be disposed
of in a special way, e.g. coolants or engine
oils that must be replenished regularly, the
safety instructions of the manufacturer of
the hazardous substances or fuels and the
applicable regional waste disposal
regulations must be observed. Also
observe the relevant safety instructions in
the product documentation.
6. Depending on the function, certain products
such as RF radio equipment can produce
an elevated level of electromagnetic
radiation. Considering that unborn life
requires increased protection, pregnant
women should be protected by appropriate
measures. Persons with pacemakers may
also be endangered by electromagnetic
radiation. The employer is required to
assess workplaces where there is a special
risk of exposure to radiation and, if
necessary, take measures to avert the
danger.
7. Operating the products requires special
training and intense concentration. Make
certain that persons who use the products
are physically, mentally and emotionally fit
enough to handle operating the products;
otherwise injuries or material damage may
occur. It is the responsibility of the
employer to select suitable personnel for
operating the products.
8. Prior to switching on the product, it must be
ensured that the nominal voltage setting on
the product matches the nominal voltage of
the AC supply network. If a different voltage
is to be set, the power fuse of the product
may have to be changed accordingly.
9. In the case of products of safety class I with
movable power cord and connector,
operation is permitted only on sockets with
earthing contact and protective earth
connection.
10. Intentionally breaking the protective earth
connection either in the feed line or in the
product itself is not permitted. Doing so can
result in the danger of an electric shock
from the product. If extension cords or
connector strips are implemented, they
must be checked on a regular basis to
ensure that they are safe to use.
11. If the product has no power switch for
disconnection from the AC supply, the plug
of the connecting cable is regarded as the
disconnecting device. In such cases, it
must be ensured that the power plug is
easily reachable and accessible at all times
(length of connecting cable approx. 2 m).
Functional or electronic switches are not
suitable for providing disconnection from
the AC supply. If products without power
switches are integrated in racks or systems,
a disconnecting device must be provided at
the system level.
12. Never use the product if the power cable is
damaged. By taking appropriate safety
measures and carefully laying the power
cable, ensure that the cable cannot be
damaged and that no one can be hurt by
e.g. tripping over the cable or suffering an
electric shock.
13. The product may be operated only from
TN/TT supply networks fused with max.
16 A.
14. Do not insert the plug into sockets that are
dusty or dirty. Insert the plug firmly and all
the way into the socket. Otherwise this can
result in sparks, fire and/or injuries.
15. Do not overload any sockets, extension
cords or connector strips; doing so can
cause fire or electric shocks.
16. For measurements in circuits with voltages
V
> 30 V, suitable measures (e.g.
rms
appropriate measuring equipment, fusing,
current limiting, electrical separation,
insulation) should be taken to avoid any
hazards.
17. Ensure that the connections with
information technology equipment comply
with IEC 950/EN 60950.
18. Never remove the cover or part of the
housing while you are operating the
product. This will expose circuits and
components and can lead to injuries, fire or
damage to the product.
1171.0000.42-02.00 Sheet 3
Safety Instructions
19. If a product is to be permanently installed,
the connection between the PE terminal on
site and the product's PE conductor must
be made first before any other connection
is made. The product may be installed and
connected only by a skilled electrician.
20. For permanently installed equipment
without built-in fuses, circuit breakers or
similar protective devices, the supply circuit
must be fused in such a way that suitable
protection is provided for users and
products.
21. Do not insert any objects into the openings
in the housing that are not designed for this
purpose. Never pour any liquids onto or into
the housing. This can cause short circuits
inside the product and/or electric shocks,
fire or injuries.
22. Use suitable overvoltage protection to
ensure that no overvoltage (such as that
caused by a thunderstorm) can reach the
product. Otherwise the operating personnel
will be endangered by electric shocks.
23. Rohde & Schwarz products are not
protected against penetration of water,
unless otherwise specified (see also safety
instruction 1.). If this is not taken into
account, there exists the danger of electric
shock or damage to the product, which can
also lead to personal injury.
24. Never use the product under conditions in
which condensation has formed or can form
in or on the product, e.g. if the product was

offset (>1 kHz), the CDP m easurements are inaccurate
and a synchronization of the analyzer and the

offset can be corrected by tuning the transmitter or
center frequency of the analyzer. It is recommended to
synchronize the analyzer and t he DUT via the refer ence
input of the analyzer.
Setting: Synchronizing the reference frequencies
The synchronization of the reference oscillators both of the DUT and analyzer strongly reduces the
measured frequency error.

3 Setup for Base Station Tests
Caution:
Before turning the instrument on, the following conditions must be fulfilled:
• Instrument covers are in place and all fasteners are tightened.,
• Fan openings are free from obstructions.
• Signal levels at the input connectors are all below sp ecified maximum values. The
level at the R&S
no circumstances be exceeded.
• Signal outputs are correctly connected and not overloaded.
Non-compliance with these instructions may cause damage to the instrument .
This section desc ribes how to se t up the anal yzer for W CDMA base s tation tes ts. As a prer equisite for
starting the test, the instrument must be correctly set up and connected to the AC power supply as
described in chapter 1 of the oper ating manual for the analyzer. Furth ermore, the applic ation firmware

signal source to the rear reference input of the analyzer (EXT REF IN/OUT).
To ensure that the error limits specif ied by the 3GPP stand ard are met, the an alyzer sho uld use an
external reference f requency for frequency measur ements on base stations. A r ubidium frequency
standard may be used for instance as a reference source.
! If the base station is provided with a trigger output, c onnect this output t o the r ear tri gger i nput of the
analyzer (EXT TRIG GATE).

4 WCDMA Test Models
For measurements on base-station signals in line with 3GPP, test models with different channel
configuration are specified in the document "Base station conformance testing (FDD)" (3GPP TS
25.141
The channel config ur ations of tes t models 1 to 4 can b e measured properl y if at le as t R&S
installed on the an alyzer. In additio n to the data channels cont ain in g p ilo t symbols, the speci al c h ann els
SCCPCH and PICH will be detected both in CODE CHAN AUTOSEARCH and CODE CHAN
PREDEFINED mode. I n mode CODE C HAN PREDEFIN ED the 3GPP test models 1 to 4 c an be used
for the measurement at a keystroke (see softkey CODE CHAN PREDEFINED for a detailed
description).
The channel configuration for test model 5 according to 3GPP contains channels in which the
modulation type can var y. Those chan nels can b e meas ured both i n CODE CHAN AUTOSEARCH and
CODE CHAN PREDEFI NED mode if the analyzer is equipped wit h R&S
model 5 can be used as well at a keystroke in mode CODE CHAN PRED EFIN ED .
