Enhanced fading functions for WCDMA 3GPP with option ABFSB49
ABFSB49 extends the functionality of the baseband fading simulator ABFS to include WCDMA 3GPP
channel simulation. It adds three new modes to the fading simulator so that all scenarios defined in
3GPP Release 99 can be simulated:
•In fine delay mode, fading simulator resolution is increased to 1 ns with up to four paths being
available.
•In moving delay mode, two paths are simulated: for one path the delay remains constant, whereas
for the other path the delay varies continuously.
•In birth-death mode, there are two paths changing delay in steps in accordance with the 3GPP
channel model.
Specifications
The enhanced fading functions for WCDMA 3GPP are only available for the ABFS standard fading
simulator, not for the second fading simulator (option ABFS-B2).

Observing the safety instructions will help prevent personal injury or damage of any kind caused by
dangerous situations. Therefore, carefully read through and adhere to the following safety instructions
before putting the product into operation. It is also absolutely essential to observe the additional safety
instructions on personal safety that appear in other parts of the documentation. In these safety
instructions, the word "product" refers to all merchandise sold and distributed by Rohde & Schwarz,
including instruments, systems and all accessories.
Tags and their meaning
DANGER This tag indicates a safety hazard with a high potential of risk for the
user that can result in death or serious injuries.
WARNING This tag indicates a safety hazard with a medium potential of risk for the
user that can result in death or serious injuries.
CAUTION This tag indicates a safety hazard with a low potential of risk for the user
that can result in slight or minor injuries.
ATTENTION This tag indicates the possibility of incorrect use that can cause damage
to the product.
NOTE This tag indicates a situation where the user should pay special attention
to operating the product but which does not lead to damage.
These tags are in accordance with the standard definition for civil applications in the European
Economic Area. Definitions that deviate from the standard definition may also exist. It is therefore
essential to make sure that the tags described here are always used only in connection with the
associated documentation and the associated product. The use of tags in connection with unassociated
products or unassociated documentation can result in misinterpretations and thus contribute to personal
injury or material damage.
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.

Safety Instructions
1171.0000.42-02.00 Sheet 3
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
Vrms > 30 V, suitable measures (e.g.
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.
