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
Page 11
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.

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.
With BTSs using a

Caution: The level at the FSE input of +20 dBm with a 0 dB input attenuator must under no
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).

BTS setting:
At least 1 slot on the selected ARFCN must be active. All slots may be occupied.
The measurement can also be performed on BTSs with active SFH (slow frequency hopping).
FSE/FSIQ measures at the set r eceive frequency (ARFCN). If a number of bursts > 1 is set, only
results are considered at which FSE/FSIQ is able to synchronize. Thus even if the carrier frequency
of the slot to be measured changes cyclically in successive frames, only slots with the set slot
number at the selected ARFCN will be considered in the measurement.
However, this will considerably slow down the measurement sequence (approx. by the factor 8
against a non-hopping BTS). This disadvantage can be avoided if a trigger signal is pr ovided for the
FSE/FSIQ (triggering not on every frame but only if the selected slot is at the set ARFCN).

BTS setting:
At least three neighbouring slots of a TDMA frame of equal power must be active.
If the BTS supports SFH (slow frequency hopping), SFH should be selected.
FSE/FSIQ measures at the set r eceive fr equency (ARFCN). If a num ber of bursts > 1 has been set,
only measurement results will be considered at which FSE/FSIQ is able to synchronize. Thus even if
the carrier frequency of the slot to be measured changes cyclically in successive frames, only slots
with the set slot number at the selected ARFCN will be considered in the measurement.
However, this will considerably slow down the measurement sequence (approx. by the factor 3
compared to a BTS without SFH). This disadvantage can be avoided if a trigger signal is provided
for the FSE/FSIQ (triggering not on every frame but only if the selected slot is at the set ARFCN).
Step 3
ô
Explanation concerning SYNC TO MIDAMBLE:
If option FSE-B7 is built in and the softkey is active, FSE/FSIQ uses the vector signal analyzer to
synchronize to the midamble. Power measurement is performed in the scalar spectrum analyzer
mode by means of the time reference obtained by th signal demodulation.
Thus an accurate and updated tim e reference is ensured (even with a jittered trigger puls e). If the
softkey is not active, the vector analyzer mode is off and FSE/FSIQ uses the time reference set
using ADJUST TRIGGER.

BTS setting:
A single timeslot should be active on the transceiver (TRX) to be measured, all other timeslots of the
TDMA frame should be set to IDLE.
The measurement can also be performed if the BTS is in the SFH mode if option FSE-B7 is
installed and
To accelerate the measurement, switch off SFH on the BTS.
ô
Explanation concerning SYNC TO MIDAMBLE:
If option FSE-B7 is built in and the softkey is active, FSE/FSIQ uses the vector signal analyzer to
synchronize to the midamble. Power measurement is performed in the scalar spectrum analyzer
mode by means of the time reference obtained by th signal demodulation.
Thus an accurate and updated tim e reference is ensured (even with a jittered trigger puls e). If the
softkey is not active, the vector analyzer mode is off and FSE/FSIQ uses the time reference set
using ADJUST TRIGGER.
SYNC TO MIDAMBLE
is active in FSE/FSIQ.
Step 3
í
FSE/FSIQ measures at the set r eceive fr equency (ARFCN). If a num ber of bursts > 1 has been set,
only measurement results will be considered at which FSE/FSIQ is able to synchronize (only if
softkey
measured changes cyclically in successive frames, only slots with the set slot number at the
selected ARFCN will be considered in the measurement.
However, this will considerably slow down the measurement sequence (approx. by the factor 3
compared to SFH). This disadvantage can be avoided if a trigger signal is provided for the
FSE/FSIQ (triggering not on every frame but only if the selected slot is at the s et ARFCN). In this
case, the measurem ent can be perf ormed at s low frequency hopping without synchronization to the
midamble.
SYNC TO MIDAMBLE
is activated). Thus even if the carrier frequency of the slot to be

2 General Information on Option FSE-K11
This application allows the following measurements to be performed on GSM900, DCS1800 or
PCS1900 base stations in line with standards (GSM 11.20, GSM 11.20-DCS, GSM11.21 and J-STD007 Air Interface) in a very convenient way:
•
PFE Phase/frequency error
•
CPW Carrier power
•
PVT Power versus time
•
MOD Spectrum due to modulation
•
TRA Spectrum due to transients
•
SPU Spurious emissions
This chapter gives basic information on the sequence of operations, settings and messages of the
instrument. Details on the individual m easurements will be found in chapter 3. The information given
under "General Remarks" is not needed for normal test operation. It is intended to provide a better
understanding of instrument settings and operations.
Cold Start
Warm Start
Opening FSE-K11
Changing within FSE-K11
A complete reset to default values is made.
The previous status is assumed to a large extent. This applies to all
parameter values and to the selected measurement. The settings
specific to the type of measurement and band are made. The default
measurement type (LIST/SINGLE) is selected. The result history is
cleared, so the results of previous measurements are no longer
available after a warm start !
Re-opening FSE-K11
Action: Exiting FSE-K11 via the mode m enu, changing to non-FSE-K11
mode, re-opening FSE-K11.
The response is the same as with a warm start except that the result
history remains stored.
Changing between FSE-K10 and FSE-K11
Action: Switching between FSE-K10 and FSE-K11 via the mode menu.
The response is the same as with a cold start.
Changing the standard
Each change of standard causes a complete r eset to the default values
valid for the standard in question. The reset is performed without any
warning to the user.
Changing the phase
Changes of phase are perform ed with as few modific ations as possible.
If problems due to incom patibility of output data are detected during a
phase change, the responsible group of parameters is reset to default
values. In such case a tempor ary message is output inf orming the user
of the modifications made.
With IEC/IEEE-bus control, the response is the same as with a change

Changing the measurement type
When the measur ement type is changed (eg from SPU to MOD), initial
actions (basic settings) specific to the selected measurement type are
performed once. A def ault band or the band last active is selected. LIST
measurement (for SPU, TRA, MOD) or SINGLE measurement (PFE,
PVT) can be selected as the measurement mode. In the case of the
CPW m enu being opened, the measurement last active is selected as
the measurement mode.
Changing the band
If the band is changed, no visible responses take place as a rule.
There are no other settings or initial actions performed.
The response is the same as with a change of
measurement type (see below).
2.1 Sequence of Operations of FSE-K11 Measurements
Measurements performed with FSE-K11 can be divided into 2 types according to their sequence of
operations:
Measurements with and without pre-measurement
a
b
In the pre-measurement, the currently applied signal level, which is essential for the main measurement,
is determined if requir ed for the selected m easurement. T his applies to all relative meas urements ( see
below) which are based on a reference value. If the measured s ignal level is below a minimum value
(expected value –20 dB), the measurement is interrupted and a warning is output. Otherwise the m ain
measurement is performed.
On opening a measurement menu, presettings are first performed which set the FSE/FSIQ to the
default state required for the m easurem ent type in question. On starting the m easurem ent, the settings
required for the selected measurement are carried out. Then the measurement is performed, if
necessary in several consecutive steps. At the end of the measurement, post-settings (such as the
activation of markers) are made if necessary and results are displayed.

Measurements of the spectrum due to modulation require a reference value for the limit lines to be
measured at 30 kHz bandwidth. To evaluate the actual carrier power (ie the signal power measured at
infinite bandwidth) a bandwidth-dependent correction value is added to the pre-m easured value: this is
at present 8 dB for 30 kHz (following GSM 05.50). The corrected value is also used for selecting the limit
lines.
The following diagram shows the sequenc e of operations of a m easurement perf ormed with FSE-K11.
This diagram applies to all measurem ents except for the CPW /CPI meas urement, which is shown in a
separate diagram (for sequence of operations see also chapter 3).
The measurement type is selected in the main menu. Prior to this, general settings are performed if
necessary, with most parameters also being acc essible from the side menus of the measur ements. On
opening a measurement menu, general settings specific to the measurement in question are made.
These settings are made only once. In the basic menu for a given measurement, the results of the
measurement last perfor med (table) are displayed in the full-screen mode (MOD , TRA, SPU, CPW ) on
opening the menu. For the CPI, PVT and PFE measurements, on the other hand, the screen settings for
the main measurement are activated immediately (for CPI the table cannot be displayed in the fullscreen mode). For MOD and SPU the band can be selected. T he table contents change depending on
the selected band.
The measurem ent start initiates the (f irst) pre-m easurem ent. After com pletion of the pre-m easurem ent,
the measured signal level is evaluated. If the pre-measurement is succ essful, either the second premeasurement is performed with optimum sensitivity (for PVT) or the m ain measurem ent is carried out
with level control orientated to the pre-measurement. The result is displayed at the end of the
measurement.

FSE-K11 Sequence of Operations of FSE-K11 Measurements
The above chart presents the PVT measurement in detail. The sequence of oper ations is deter mined by
the setting for the pre-measurement –
With AUTO, the PVT measurement is performed as follows:
1st pre-measurement - 2nd pre-measurement - main measurement.
The settings for the fir st pre-m easurem ent (with m ax. 2 measured burs ts) ar e m ade in acc ordance with
the expected level. The settings for the second pre-measurement are made in accordance with the
signal level determined in the first pre- measurement, and level measurement is performed with max.
20 burs ts. The signal level determined in the second pre-m easurement is us ed as a reference for the
limit lines used in the subsequent main measurement.
Two-stage pre-measurement results in highly accurate level determination even in cases where the
signal level is considerably below the expected value since, thanks to the follow-up level control, it is
ensured that the measurement is always performed with optimum sensitivity.
With the USER setting, the pre-measurem ents are skipped, and the level determined in the last premeasurement is used both for setting the operating point and as a reference f or the limit lines. If no level
has been determined, the nominal value (expected signal level) is used.
This setting allows fast switching between the various burst views (Rising, Falling, Full, HighRes).
Actuating the Start RefMeas key will trigger a sequence of two pre-measurements without any main
measurement following.

34 FSE-K11 waits for the trigger event, then starts or continues the sweep.
35 The sweep is enabled.
36 Measured data are collected until the end of the sweep or, with gated sweep, during a specific
gate time.
37 It is checked if the sweep is terminated.
38 It is checked if the number of preset s weeps has been attained AND if the measurement is of
the SINGLE or the LIST type.
39 The m easurement is completed if the preset number of sweeps has been attained and the
measurement is of the SINGLE or the LIST type.
If digital demodulation is active, there are s ome dif ferenc es concerning tr igger logic as com pared to the

FSE-K11 Sequence of Operations of FSE-K11 Measurements
The sequence of operations of a CPW m easurement ( BTS/K11) is shown above. The m easurement is
initiated by pressing the ’MEAS MAX OUTPUT PWR’ key. Then either the static or the dynamic power
control level can be increm ented as required. Each increm entation of the static power control level will
reset the dynamic power control level to 0 (zero). If the initializing k ey ’MEAS MAX OUTPUT PW R’ is
actuated again during the current session, the session is aborted (measurement status: ABORTED).
Entries by the user are dependent on the availability of keys ’INC STATIC PWR LEVEL’ and ’INC
DYNAM PWR LEVEL’: if the maxim um value of the dynamic power control level is attained, the ’INC
DYNAM PWR LEVEL’ key is inhibited so that only the static power control level can be increased. If the
maximum value is attained here too, pressing the key again causes the session to be term inated and
the total result to be displayed on the full screen.
With the ’full-screen table’ status, both INC keys are inhibited, and a new session can be started only by
pressing the ’MEAS MAX OUTPUT PWR’ key.
Unlike the CPW measurement, the CPI m easurement allows any single carrier-power m easurements.
In contrast to all other measurements performed with FSE-K11, single CPI measurements are not
related to one another. There is no total result for the session. The CPI menu can be exited and
activated any time without this having any effect on the table contents of the CPI measurement.
CPI measurements are intended m ainly for developm ent engineers in the lab who m odify parameter s of
their workstation and want to investigate the effect s thereof on the carrier power. CPW m easurem ents,
on the other hand, are aimed at verifying compliance with acceptance test specifications of the GSM
standard.
CPI measurements, therefor e, are only used for evaluating absolute levels; no relative c ompar isons are
made between the levels obtained with different power control level settings. Operator control is
described in the additional information following the description of the softkey menus.

Sequence of Operations of FSE-K11 Measurements FSE-K11
2.1.1 Errors and Failures During Measurements
There are three main sources of error in GSM measurements:
Carrier signal missing:
Causes: Wrong operating frequency (ARFCN), SFH active, test line defective or incorrect
attenuation, wrong power class
Effects: Pr e-m easurem ent: inadequate power meas urem ent (eg average meas urement with
SFH), measurement is aborted.
Sweep stops (in measurements with midamble synchronization).
Main measurement: s weep stops when midamble synchronization (PFE, PVT, CPW)
is active and number of bursts > 1. When signal is applied again,
the sweep continues.
Trigger missing:
In all triggered measurements: sweep stops (indicated by trigger LED).
The following is recommended for the trigger source:
•
Optimal solution: External trigger. This allows all measurements without restrictions.
•
FreeRun: Allowed for SPU and TRA if not possible otherwise
(MOD-Tx without gating also possible).
Burst missing:
Causes: SFH active, wrong frame trigger
Effects: In triggered measurements, limit lines may be exceeded (PVT);
sweep stops (in measurements with midamble synchronization).
2.1.2 Abort of Measurements
a) Abort by User
In manual operation, each running measurem ent can be aborted by pressing the start k ey again (ie the
key with which the measurement was started).
Starting another measurement likewise caus es an abort of the running m easurem ent. This also applies
to switchover from SINGLE to CONTINUOUS or LIST, for example.
all
Measurements are also aborted on exiting the menu in question (New! From 1.90 for
or modifying a test parameter (even in side menus).
measurements)
All aborts, except for spurious single-step measurements, are without warning. Only if – during a running
spurious single-step measurem ent – the user attempts to res tart this measurem ent or to start the LIST
measurement, is he queried to confirm the (re)start before it is made.
For remote control, a special ABO RT comm and is available which causes the current measurem ent to
be aborted (see manual for IEC/IEEE-bus control).
1057.3440.41 2-18 E-3
Page 86
FSE-K11 Sequence of Operations of FSE-K11 Measurements
b) Abort by Instrument
Measurements are norm ally performed until the end. Only in the case of insuff icient carrier power (see
above) are measurements aborted after the pre-measurement and an error message is output.
If the maximum num ber of table entries (presently 50) is exceeded in a (spurious) measurement, the
measurement is continued but no new entry is made in the table. This does not apply to the CPW
measurement, where all possible single results (7 x 16 = 112) are entered in the table. In CPI
measurements, the last 40 single measurements are stored.

One summary entry for eac h section (see below).
The result tables of the MOD-LIST Rx/Tx and SPU measurements are arranged in groups:
The whole measurement range is divided into frequency sections.
A summary entry is generated for each section. T his entry contains the section lim its and the m axim um
level of the worst quality class measured in this section. All "events" are then listed as frequency-level
pairs, an event being a measured value which lies above limit or at least in the tolerance range.
Each measured value is assigned one of the following quality classes:
• PASSED (best quality class)
• MARGIN
• EXCEPTION
• FAILED (worst quality class)
1057.3440.41 2-19 E-3
Page 87
Sequence of Operations of FSE-K11 Measurements FSE-K11
PASSED values are measured values below the tolerance range.
MARGIN values are values below the limit value but within the (user-definable) tolerance range.
EXCEPTION values are values above the limit value but not exceeding the threshold for outliers.
FAILED values violate both the limit value and the exception threshold.
All measured values except PASSES are events in the above sense.
The section entries (and the table as well) are assigned either PASSED or FAILED as a summary
evaluation.
If the number of outliers measured in one section exceeds the value defined by the standard, the section
is assigned FAILED even if all events are assigned EXCEPTION in the worst case.
The tables may contain a maximum of 50 lines (except for Carrier Power, where the maximum is
100 lines).
In some measur ements, theref ore, it may happen that FAILED is indic ated as a summ ary evaluation in
the table header although all visible entries in the table are evaluated PASSED.
The reason for this is that the FAILED evaluation m ight be output in the 65th line only and is therefore
not visible.

FSE-K11 Exiting FSE-K11
2.2 Exiting FSE-K11
When FSE-K11 is exited, the status las t active is stor ed so that it can be restor ed as f ar as possible on
re-opening FSE-K11. The FSE-K11 settings are largely transferred to the other operating modes to
allow FSE-K11-conformal measurements also in these modes as far as this is expedient.
FSE-K11 can be exited by:
•
Power off
•
Preset and mode selection
•
<Mode> key and mode selection
Power off
FSE-K11 is restarted (warm s tar t) on power-up of FSE/FSIQ. FSE-K11 is in this case not exited but only
interrupted.
Preset
The instrument is reset to a defined default status. This function is comparable to a cold start. For
FSE-K11 this means: no re-activation of the status las t ac tive when FSE-K11 is r e- opened but activation
of the default status. The target status of the instrument after a pr eset is c learly defined independently of
the previous FSE-K11 status (see paragraph "Preset" below).
Changing the mode
The target status assum ed results from the FSE-K11 st atus last active and the s elected target mode.
The parameters for the target mode are set in s uch a way that measurements in line with FSE-K11 are
possible. For changing from FSE-K11 to the analyzer and vector analyzer modes, the following is
defined:
Transformation of (FSE-K11) parameters:
Trigger
•
TrgSource compatible (if not available in target mode: FreeRun).
•
TrgLevel is taken over for all modes (if available).
•
TrgDelay corresponding to trigger last active.
•
TrgPolarity, TrgEdge/Level are taken over.
Level
•
ExtAtt is represented by RefLvl offset.
•
RefLevel is set directly.
• RF attenuation is calculated in line with FSE-K11 (AUTO or by formula).
Caution: For RX measurements, the input attenuation is set to AUTO ===> not to 0 dB !
Frequency For the zero span or the vector mode, the ARFCN frequency is set as the center
frequency.
For the frequency sweep mode, the start and the stop frequency are selected in
accordance with the band last selected:
for TX/RX the band in question (possibly incl. ±2 MHz),
for TX ±1.8 MHz the center frequency f (AFRCN) with a span of 3.6 MHz,
for SPU the section last selected (or more sim ply, the complete band of the non-T X
measurement) .
1057.3440.41 2-21 E-3
Page 89
Exiting FSE-K11 FSE-K11
Screen Full screen is taken for the analyzer target mode, split screen for the vector target mode (PFE).
Trace Trace assignment in FSE-K11:
2 for single-trace measurements in LIST mode (trace 1 used for table)
1 for single-trace measurements in SINGLE/CONT mode
1,3,2 for PVT measurements with MAX Hold, Average, MIN Hold
2 for SPU measurements
1,3,4 for PFE measurements with MAX Hold, ClearWrite, MIN Hold
2 for CPW/CPI measurements (Average)
Trace assignment is maintained as far as possible.
For changing from FSE-K11 to modes other than the analyzer or vector analyzer modes, the following is
defined:
On exiting FSE-K11, the FSE-K11 operating status last active is stored in the newly selected mode
(eg RECEIVER mode, or another mode) and activated again by this mode on re-opening FSE-K11.

General Remarks FSE-K11
2.4 General Remarks
In the case of the TRA, MOD and PVT m easurements, a pre-measurem ent is performed prior to the
main measurement.
This pre-measurement is used for defining the reference point for the limit lines.
In the case of PVT, the pre-m easurement tak es place in two s tages. In the f irst pre-m easurement with
max. 2 bursts, the actual level applied is determined. In the second pre-measurement with max.
20 bursts, the exact reference point for the limit lines is determ ined with an operating point optimally set
by means of the result of the first pre-measurement.
In the PFE, CPW and SPU m easurements, on the other hand, f ixed level values are used and thus no
pre-measurements are required.
"ExtAtt" (external attenuation) is taken into account in all measur ements in the carrier or non-T X band,
"RxGain" for all measurement in the RX band. The values have basically the same effect but are us ed
separately. RxGain can be entered any time, not only for an activated RX band measurement.
In all measurements with Min, Max and Average dis play, three traces are ac tivated only if the number of
sweeps is higher than 1. Likewise, vector triggering operates c orrectly only if the number of sweeps is
set to a value higher than 1 (this too is a feature of the basic unit). If this is not the case, an error
message is output, for example "Sync not found" if the midam ble is not detected, in whic h case there is
no synchronization to midamble.
Explanation of abbreviations used in the formulas below:
SigPwr (Expected) signal power, defined by the current settings for the power c lass and power
control level (compare section 3.3.4)
MeasPwr Measured signal power
CorrPwr Measured signal power, corrected by a value depending on the bandwidth
(30 kHz RBW: +8 dB)
MaxPwr Maximum (nominal) output power
F(ARFCN) Operating frequency, resulting from frequency setting (compare section 3.3.3)
Tx Su p 20 dB or 0 dB is taken into account in the f orm ula depending on whether TX suppression
is set to ON or OFF
ExtAtt External attenuation
RxGain RX band gain
SFH SFH (slow frequency hopping) factor: 1 for SFH OFF, 3 for SFH ON
NOB Number of bursts – value set by the user for the number of sweeps
Examples giving numbers, if any, refer to the default settings on power-up (PGSM-II).
