K10/K11 Limit Lines
For FSE options K10 and K11 (GSM mobile station and GSM base stati on anal yzer ), many internal limit
lines are used which are deri ved from the applicable s tandards. To make these limit lines access ible to
the user, they are available as data sets. There are 6 data sets:
K10_XGSM.LIA Limit lines for mobiles, standards EGSM, PGSM and RGSM
K10_DCS.LIA Limit lines for mobiles, standards DCS1800 (GSM 1800)
K10_PCS.LIA Limit lines for mobiles, standards PCS1900 (GSM 1900)
K11_XGSM.LIA Limit lines for base stations, standards EGSM, PGSM und RGSM
K11_DCS.LIA Limit lines for base stations, standards DCS1800 (GSM 1800)
K11_PCS.LIA Limit lines for base stations, standards PCS1900 (GSM 1900)
To load the data sets, proceed as follows:
1. Copy the desired data sets (one or several) from the CD to disk or analyzer.
2. Press the hardkey RECALL, and enter path (for example A:\) via softkey EDIT PATH
(see operating manual, section 2.7.3).
3. Select menu item “Lines“ via softkey ITEMS TO RECALL
(this is the default setting; see operating manual, section 2.7.3.1).
4. Select the desired data set via softkey DATA SET LIST. This will cause all limit lines of the selected
data sets to be copied to the limit line directory of the instrument.
From the GSM software, the limit lines can be accessed and edited via the softkey EDIT in the
righthand side menus of the following measurements:
•
Power vs time
•
Modulation spectrum
•
Transient spectrum or
•
Spurious
Outside GSM measurements, the limit lines are accessible in the analyzer mode of the instrument.

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

FSE-K11 Presetting the FSE/FSIQ
1 Getting Started
This chapter is mainly intended for operators using the GSM BTS analyzer mode for the first time.
Operators are guided step by step through the most frequent base station tests.
The chapter describes FSE/FSIQ setup, relevant settings and individual measurements.
Layout and content are application-oriented and provide important information on FSE/FSIQ as well as
the GSM/DCS1800/PCS1900 system.
It is recommended to read through this chapter and perform the operations on the FSE/FSIQ at the
same time. T his ensures a simple and rapid introduction to the GSM BTS firmware func tions so that
correct and useful measurement results are achieved.
Some of the steps are provided with reference num bers, eg , relating to a m ore detailed information
on the opposite page.
For more detailed information on the individual menus and softk eys kindly refer to the reference part in
chapter 2.
Note: The descriptions of some of the functions are provided with notes pointing out that some
functions of FSE-K11 are available only if Vector Signal Analysis Option FSE-B7 is
installed. These notes apply only to FSE, since FSIQ c ontains this option in the basic
version.

Additional information
The stringent requirements for measurements of spurious in the RX band on BTSs using a
combined RX input/TX output demand adequate suppression of the carrier signal(s) (max. carr ier
level < -10 dBm at the FSE/FSIQ input), eg with the aid of bandstop filters and/or diplexers. Since
the requirements for G SM phase 1 are more severe than those f or phase 2, an external low-noise
preamplifier may be required in addition because of the higher noise floor of FSEB, FSEM and
FSEK compared to FSEA.

circumstances be exceeded.
The following warning is output when the RX-BAND softkey is pressed on the screen.
Caution:
Connect bandpass or bandstop to suppress TX-band!
Notes on amplifier:
The noise figure of the preamplifier should be as low as possible (LF < approx. 6 dB) and the gain in
the range 15 to 25 dB so that the noise floor of FSE/FSIQ (approx. 15 to 17 dB with FSEA30,
approx. 18 to 21 dB with FSEB/M/K30) can be neglected.
Make sure that the preamplifier is not overdriven by insufficiently suppressed TX signals (for this
reason the amplifier gain should not be too high).
