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.

This tag indicates a situation where the user should pay special attention
to operating the product but which does not lead to 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.

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.

FSE-K10 Getting Started

1 Getting Started

This chapter is mainly intended for users operating the GSM MS analyzer mode for the first tim e. User s
are guided step by step through the most frequent tests that are performed on mobiles.

User guidance starts with connecting FSE/FSIQ and making the required presettings before the
individual measurements are explained.

The layout and contents of this chapter are applic ation-oriented and provide important inform ation on
FSE/FSIQ as well as the GSM900/DCS1800/PCS1900 system.

It is recommended to read through this chapter and at the same time perform the operations on
FSE/FSIQ. This ensures a simple and rapid introduction to the GSM MS firmware functions so that
correct and useful measurement results are achieved.

Each individual step is provided with a reference number, eg , relating to a more detailed inform ation
on the opposite page.

General information on FSE-K10 is provided in chapter 2. Chapter 3 gives detailed information on
menus and softkeys and contains a graphical menu overview. Remote-control commands and their
assignment to softkeys is described in chapter 4.

Note: The descriptions of some of the functions are pr ovided with a note to the effect that thes e

functions are available only with Vector Signal Analysis Option FSE-B7 installed. This note
applies only to FSE, while FSIQ contains these functions already in the basic version.

1.1.1 Standard Test Setup

In general, a system simulator (eg CRTP or also CMD from R&S) is required to test the m obile. This
system simulator makes the necessary measurement-specific settings and provides the necessary
frequency accuracy of the mobile.

The mobile has to be equipped with a test SIM.
If the mobile has a special service mode, most of the measurements can be performed without a

system simulator (exception: frequency errors. To attain the required frequency accuracy, the mobile
needs a corresponding synchronization burst).

À Connect antenna output (or TX output) of MS to FSE/FSIQ RF input via a coupler of suitable

attenuation (eg 20 dB).
For measurements of the spectrum due to modulation in the RX band, the attenuation between the
mobile’s antenna output and the FSE/FSIQ input must not exceed 6 dB. The TX signal must be
suppressed by at least 25 dB by means of a bandstop filter.

MS setting:

The measurement can also be performed on MSs with active SFH (slow frequency hopping).
FSE/FSIQ measures at the set receive frequenc y (ARFCN) . If a number of burst s > 1 has been s et,
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 midamble at the selected ARFCN will be considered in the measurement. However, this
will considerably slow down the measurement sequence (approx. by the factor 3 against a non­hopping MS). 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).

The MS needs to receive a suitable synchronization burst from the system simulator for the
frequency error to be measured correctly.

ô

Explanation of 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 the 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.

Measurement type
When the measurement t ype is changed (eg f rom spurious to s pectrum
due to modulation), initialization actions (basic settings) specific to the
selected measur ement type are performed onc e. A default band or the
band last active is selected. List m easurement (for spurious, spectrum

measurement type. In the case of the carrier power menu being entered,
the measurement last active is selected as measurement type.

Change of band
If the band is changed, no visible responses take place as a rule.
No other settings or initializations are made.

Sequence of Measurement Operations FSE-K10

2.1 Sequence of Operations of FSE-K10 Measurements

Measurements performed with FSE-K10 can be divided into 2 types according to their sequence of
operations:
Measurements with and without premeasurements.

a)

b)

In the premeasurement, the currently applied signal le ve l, whic h is es sential for the main measurement,
is determined as r equ ired for the selected measur em ent. T h is app lies t o a ll r e la ti ve measurements (see
below) which are related to a refer ence value. If the measured signal level is below a m inimum value

(value expected –20 dB), the measurement is interrupted at this point and a warning is output.
Otherwise the subsequent main measurement is performed.

On activating a measurement menu, presettings are first performed which set the FSE/FSIQ to the
default state requir ed for the m easur ement type in q uestion. On s tarting the m easurem ent, the settings
required for the selec ted meas urement are car ried out. The measurem ent is then perfor med in several
consecutive steps, if necessary. At the end of the measurement, post settings (such as activating
markers) are performed and the result is displayed.

2.1.1 General Description of FSE-K10 Measurements

The following diagram shows the sequence of operations of a m easurement perfor med with FSE-K10.
This diagram applies to all m easurem ents ex cept for the C PW/CPI m easur ement, which is shown on a
separate diagram (see also chapter 3).

The desired measurement is selected in the main menu. General settings may be made before the
selection of the meas urement. Mos t par am eters ar e also a vaila ble f or adjus tm ents via t he s ide menu of
each measurement. On opening th e meas urement m enu, general s ettings s pecific to the m easurem ent
concerned are performed once. In the basic menu for a given measurement, the results of the
measurement last perf ormed ( table) are displa yed in the f ull-screen m ode (MOD, TR A, SPU, CPW ) on
calling up the menu. For the CPI, PVT and PF E m easurem ents, on the other hand, the s creen settings
for the main m easurement are activat ed immediatel y (for CPI the tab le cannot be dis played in the full­screen mode). For MOD and SPU the band can be s elected. T he table conte nts change dep ending on
the selected band.

The measurement start i nitiates the (first) premeas urement. After completion of the premeasurement,
the measured signa l level is evaluat ed. In the go case, a second premeasurement is perform ed (for
PVT) with optimum sensitivity or the main measurement with level setting related to the
premeasurement. The result is displayed at the end of the measurement.

Sequence of Measurement Operations FSE-K10

The above chart presents the PVT measurement in detail. The sequence of operations is determined by

the setting for the premeasurement –
With the AUTO setting, the PVT measurement is performed as follows:

1st premeasurement - 2nd premeasurement - main measurement
The settings for the f irst premeas urement (with max . 2 measured bursts) are made in accor dance with
the expected level. The settings for the second premeasurement are made in accordance with the
signal level determined in the first premeasurement, and level measurement is performed with max.
20 bursts. The sig nal level determined in the second prem easurement is used as a reference for the
limit lines of the subsequent main measurement.
This two-stage proc edure results in highl y accurate level determ ination even in cases where the sign al
level is muc h belo w th e ex pec t ed va lue s ince, tha nks to the follow-up level c on t rol, i t is ens ure d that the
measurement is always performed with optimum sensitivity.

In the USER setting, the prem easurements are skipped and the le vel resulting from the most recent
premeasurement is us ed as the operating poi nt setting and also as the limit l ine reference. 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).

Looked at in detail, each (pre-)measurement consists of the following operations:
19 The settings needed for the intended measurement are made.

20 Synchroni zation to midamble is optional f or PVT and CPW/CPI and mandatory for PF E. This

choice is available only if Option FSE-B7 is fitted.
30-39 Measurement without digital demodulation (= option B7).
31,33 MOD measurem ents m ay requir e a "Ga ted Sweep ", ie a fr equenc y sweep m ade only a t spec if ic

times. For this purpose, an external gate signal (comparable to trigger) is indispensable.
32,33 Unless FreeRun was sel ected, the trig ger e vent (ex ternal; option all y, for FSE- K10 a lso video or

RF power) is required before continuing .
34 FSE-K10 waits for trigger event, then starts or continues the sweep.
35 The sweep is enabled.
36 Collection of measured data until end of sweep or, with gated sweep, during a specific gate

time.
37 Check if sweep is terminated.
38 Test: Check if number of preset sweeps has been attained AND if meas urement is of Single

type or List type.
39 The measurement is completed if the preset number of sweeps has been attained and the

measurement is of the Single type.

Sequence of Measurement Operations FSE-K10

The sequence of operations of a CPW measurement (BTS/K11) is described on the previous page.
The sequence of the CPW measurement for MS (FSE-K10) differs from that of the BTS by the
replacement of the 2 power control stages by a single one which is swept in strict sequential mode.
The measurement is initiated b y pres s ing the M EA S MAX O UTPUT PWR softkey. Then either the static
or the dynamic power control le vel can be incremented as require d. Each incrementation of the static
power control level wil l reset the dynam ic power c ontrol leve l to 0 ( zero) . If the initi ali zing sof tk e y MEAS
MAX OUTPUT PWR is actuated during the current session, the session is aborted (measurement
status: Aborted).
Entries by the user are controlled by the availability of softkeys INC STATIC PWR LEVEL and INC
DYNAM PWR LEVEL. if the maximum value of the d ynamic power co ntrol level is attained, the INC
DYNAM PWR LEVEL softke y is inhibited so that onl y the static power contr ol level c an be i ncreased. If
the maximum value is attained here too, pressing the softkey again causes the session to be terminated
and the total result to be displayed on the full screen.
In the ’full-screen table’ status, both INC softkeys are inh ibited and a new session ca n be started only
by pressing the MEAS MAX OUTPUT PWR softke y.

Unlike the CPW measurement, the CPI m easurement allows an y single carrier-power m easurements.
In contrast to all other measurements of FSE-K10/K11, single measurements have no inherent
relationship. There is no total r esu lt of the sess ion. T he CPI menu can be exited and acti vated a ny tim e
without any effect on the table contents of the CPI measurement.
CPI measurements are mainl y intende d for development engineers in the l ab who modify parameters of
their workstation and want to investi gate the eff ects thereof on th e carrier po wer. CPW measurements ,
on the other hand, are aimed at complying with acceptance test specifications for the GSM standard.
CPI measurements, therefore, only evaluate absolute levels and make no relative comparisons
between the levels of different power control level settings. Operator control is described by the
additional hints following the description of the softkey menus.

The following overview gives a classification of the Kxx measurements according to the above diagram:

The spectrum-due-to-modulation measurements provide a reference value for the limit lines, which
should be measur ed with a 3 0 kHz bandwidth. To evaluate th e ac tu al car r ier po wer (ie the signal power
measured with infinite bandwidth) a bandwidth-dependent correction value is added to the preview
value: it is now 8 dB (analogous to GSM 05.50) for 30 kHz. The corrected value is also used for
selecting the limit lines.

Sequence of Measurement Operations FSE-K10

2.1.1.1 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: Premeasurement: insufficient power measurement (eg average measurement with

SFH), measurement is aborted.
Sweep stops (measurements with midamble synchronization)
Main measurement: sweep stops when midam ble synchroni zation (PFE, PVT , CPW)

is activated 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:

•

External trigger: allows all measurements without restrictions.

•

Video trigger: only measurements directly on the carrier are possible (PFE, PVT, CPW/CPI)

•

RF power: TRA and MOD-ARFCN +/-1.8 MHz) are p ossible in addition to m easurements for

video.

•

Free Run: permissible for SPU and TRA if no other trigger source is available.

Burst missing
Causes: dummy burst, 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

2.1.2.1 Abort by the User

In manual operatio n, each run ning m easurem ent can be aborte d by pres sing the star t sof tke y again ( ie
the key with which the measurement was initiated).
Starting another measur ement lik ewise caus es an a bort of the r unning m easurem ent. This als o appli es
to switchover from Single to Continuous or List, for example.
Each measurement is als o aborted on quittin g the menu (new! As f rom 1.90 for all measur ements) or
modifying a test parameter (even in the side menu).

All aborts, except the spurious single step measurement, are without warning. Only if – during a running
spurious single-step meas urement – the user attempts to restart this m easurement or to start the Lis t
measurement, is he queried prior to the restart being made.

For remote control, a special ABORT command is available which likewise causes the current
measurement to be aborted (see manual for IEC/IEEE-bus control).

2.1.2.2 Abort by the Instrument

Measurements are nor mally perf ormed until the e nd. Onl y in the cas e of insufficient carrier p ower (see
above) are measurements aborted after the pre-measurement with an error message being output.
If the maximum number of table entries (50 at present) is ex ceeded in a spurious measurem ent, the
measurement is continued but no other entry is made in the table. In CPI measurements, the last
40 single measurements are stored.

Sequence of Measurement Operations FSE-K10

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 generate d for each sec tion. T his e ntr y contains the sec tion lim its and the m axim um
level of the worst qu ality class measured in t his section. All events are then listed as frequency-level
pairs, an event being a measured value which lies above the limit or is at least in the tolerance range.

Measured values are assigned to one of the following quality classes:

•

PASSED best quality class Results below the tolerance

•

MARGIN : values below the limit but in the tolerance range (user-defined)

•

EXCEPTION : values above the limit but still below the limit provided for

outliers

•

FAILED worst quality class values violate the limit and also the permissible exceptions

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 total evaluation .

If the number of measured outliers exceeds in one section the value defined by the standard, the
section is assigned FAILED even if all events are assigned EXCEPTION in the worst case.

The tables have 50 lines at maximum.
In some measurements, therefor e, it may happen that "fai led" is indicated as a summar y evaluation in
the table header although all visible entries in the table are evaluated "passed".
The reason for this is that the "failed" evaluation might not appear until line 50 and is therefore not
visible.

Exiting FSE-K10 FSE-K10

2.2 Exiting FSE-K10

When FSE-K10 is exit ed, the status las t active is s tored s o that t he oper atin g status c an b e r estored as
far as possible on re-entering. The FSE-K10 settings are largely transferred to the other operating
modes to allow FSE-K10- conformal meas urements also in the oth er operating modes as far as this is
expedient.

FSE-K10 can be exited by:

•

Power Off

•

Preset (mit anschließender Mode-Auswahl)

•

Taste

Power off
FSE-K10 is restarted (warm start) on power-up of FSE/FSIQ. FSE-K10 in this case is not exited but
only interrupted.

Preset
The instrument is reset to a defined default state. This function is comparable to a cold start. For
FSE-K10 this m eans: no re-activation of the last operating status on re- entering but activatio n of the
default status. The targ et status of the instrument af ter a preset is c learly def ined independent ly of the
current FSE-K10 status:
Analyzer, Frequ-Sweep Cont, Full Span, ...

MODE

mit anschließender Mode-Auswahl

Change of operating mode
The last state is a function of the FSE-K10 output state and target mode. The parameters are set for the
target mode in such a way that similar measurements to FSE-K10 are possible. For changing from
FSE-K10 to the analyzer and vector analyzer modes, the following is defined:

Transformation of (FSE-K 10) par ameters:
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-K10 (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 m ode, the start and the stop frequ ency are selected in accordanc e
with the band last selected:

for Tx/Rx band the corresponding band (possibly incl. +/- 2 MHz),
for TX ±1.8MHz the center frequency f(AFRCN) with a span of 3.6 MHz,
with SPU the last selected section (or more simply the whole band of the NTx
measurement).

Screen

Full screen is taken for the analyzer mode, split screen for the vector analyzer split-screen
mode (PFE).

1057.3140.42 2.21 E-1

Exiting FSE-K10 FSE-K10

Trace

Trace assignment in FSE-K10:

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 to other modes, the following is defined:
On exiting FSE-K10, the FSE-K10 operati ng status las t active is s tored b y the ne wl y selected m ode (eg
RECEIVER mode, or another mode) and activated again by this mode when FSE-K10 is re-entered.

1057.3140.42 2.22 E-1

Preset FSE-K10

2.3 Preset

FSE-K10 is reset to the default status. Then the following setting is assumed:
Analyzer default setting: Frequ-S we ep, Ful lSp an, S weepTime Auto, RBW/VBW Auto, Trigger Free Run,
...

2.3.1 Signal Analysis Mode

The target status assumed results from the FSE-K10 status last active (or the last measurement
performed with FSE-K10, respectively).

PFE as PVT
CPW/CPI ZeroSpan; f=f(ARFCN); SweepTime 540 µs

wg. Trace 2 is renamed trace 1 because of full-screen display.
PVT ZeroSpan; f=f(ARFCN); SweepTime 800 µs or 100 µs
MOD Frequ-Sweep; Span/Start-Stop acc. to Tx/ARFCN ±1.8 MHz/Rx; NON-Rx: trigger at

FreeRun, plus gated sweep with gate length 170 µs. Otherwise trigger is taken over

(setting analogous to CONTINUOUS measurement).
TRA FrequSweep; span 3.6 MHz, f = f (ARFCN); sweep time in accordance with TRA

formula (settings analogous to CONTINUOUS measurement).
SPU Frequ-Sweep Continuous; Start-Stop FullSpan; SweepTime AUTO. Trigger is taken

over. Trace 2 is renamed trace 1 because of full-screen display.

2.3.2 Vector Signal Analysis Mode

The PFE status of FSE- K10 (vector mode) is set irrespective of the FSE-K10 status : split screen with
result table at the top and trace at the bottom.

2.3.3 Receiver Mode etc.

In the RECEIVER mode, the status is saved upon exiting FSE-K10 and reinstated upon re-entry.

General Remarks FSE-K10

2.4 General Remarks

In the case of the T RA, MOD and PVT measurements, a pr emeasurement is perform ed prior to the
main measurement.
The premeasurement is used to define the reference point for the limit lines.
In the case of PVT , the premeasurement takes place in two stag es. In the first premeasurement with
max. 2 bursts, the actual level applied is determined. A second premeasurement with maximum 20
bursts is then perform ed, which serves to determ ine the exact reference point for the limit lines using
the operating point optimally set with the result of the first premeasurement.

In the PFE, CPW and SPU measur ements, on the ot her hand, f ixed level va lues are use d and t hus no
premeasurements are required.

"ExtAtt" (external attenuat ion) is taken into account in all m easurements in the carrier or non- TX band,
"RxGain" for all measurem ent in the RX band. The values have b asically the sam e effect but are used
separately. RxGain can be entered any time, not only for an activated RX band measurement.

In all measurements with Min, Max and Average display, three traces are activated only if the number of
sweeps is higher than 1. Likewise, vector tri ggering operates cor rectly only if the n umber 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 exam ple "S ync not f ound" if the m idam ble is not detec ted, in whic h case ther e is
no synchronization to midamble.

3.3.2 Consideration of the External Attenuation

For measurements at the RF interf ace, RF cab les, atten uator p ads, po wer spl itters, d irectiona l coupl ers
or other devices ar e used to match the level of the RF signal or connect f urther test equipment. The
attenuation from the RF interface of the transmitter to the RF input of the FSE/FSIQ can be corrected by
a constant attenuation factor.
Settings which produce a leve l >27 dBm at the input of the FSE/FSIQ – tak ing into account the other

settings -are generally not possible with the

the attenuation enter ed with E XTERNA L ATTEN is irrelevant. In
this case the RX band gain softkey has basically the same
effect.

The FSE/FSIQ switches to a n inter n al atte nua tio n of 0 d B at the

beginning of the meas urement a nd, at th e end of it, to the v alue
set prior to starting the measurement. The carrier is to be
sufficiently suppressed by appropriate measures (eg by means
of a bandstop filter). If an external attenuation is used for a
measurement in the RX band, it can be taken into acc ount via
RX BAND GAIN (negative value of RX BAND GAIN =
attenuation in the RX BAND).

If the DUT to be measured has a very high output power, an

FSE/FSIQ-internal atten uation (RF ATT) should without fail be
set. The 10 dB steps may be excessive in some cases since the
noise level increases by approx. 10 dB when adding an
attenuation of 10 dB.

If a high dynamic range is required, it is expedient to use an

external attenuation (w hich can be varied i n steps smal ler than
10 dB in most cases) in order to remedy to the large steps of
the RF ATT.

For each dB step of the external attenuator, the RF ATT is

increased by 10 dB approx. one dB later. This extends the
dynamic range.

3.3.3 Setting the Transmission Channel

The operating frequency (ie the carrier frequency) is entered via the ARFCN (Absolute Radio
Frequency Channel Num ber: the transm ission band is di vided into cha nnels of 200 kHz each of which
is identified by means of a standard-dependent number) or directly as a frequency value.
In the case of ARFCN entry, the frequency is limited to the standard range of the transmission band.
Direct entry of the operating frequenc y, on the other h and, allo ws valu es from 1.8 MHz to f
MHz; beyond the transmission band, the band definitions Tx, NTx, Rx make no sense, so only
measurements related to the carrier f requency are p ossible: this inc ludes all meas urements perf ormed

directly on the carrier - PFE, PVT, CPW/CPI – as well as the relative measurements T RA and MOD­ARFCN ±1.8MHz. If the frequenc y entered is within the Tx band, th e described lim itations need not be
taken into account.

The search range of the automatic ARFCN determination covers the whole Tx band. Due to the
features of the marker-to-peak search, an ARFCN is always determined even if no carrier signal is
active in the Tx band.

3.3.4 Setting the Transmit Power of the MS under Test

The mobile's nominal transmit power is to be reported to the FSE/FSIQ so that it can select correct
default settings such as input attenuation, reference l evel and l imit values. The mobile's transmit power
is determined by its power class and the power c ontrol level. The power class defines the maximum
possible output power of the base s tati on, wher eas the pow er c ontrol lev el determines the actual output
power.

The information on the power set in this menu enables the FSE/FSIQ to make optimal setti ngs for Ref
Lvl and attenuation in the active measurement. The formulae for determining the settings are explained
in the measurement chapters.

The limit values for a measurement, for instance, are selected with reference to the power level.
However, the coupling of limit values and the power c ontrol level may also be undone, which allows
limit values of any power control level to be used for measurements with freely selectable power.

To protect the FSE/FSIQ, the settings made in the PO WER menu are automatically checked to make
sure that the input level at the FSE/FSIQ does not exc eed 27 dBm.
(MS output power – attenuation ≤ 27 dBm).

To prevent the occurr ence of an overload, a warning is displayed for thos e s ettings whic h would lead to
the threshold level being exceeded (

POWER CTRL LEVEL)

Since the power measurement is subjected to very stringent accuracy requirements, the analyzer
should not be overdriven.
To prevent this the unit monitors the signal level determined in the preview to establish if the RefLevel is
exceeded by more than 1 dB. If this is the case, a warning is output.

In addition to the output power of the DUT the ex ternal attenuation or an external amplifier has to be
taken into account.
An attenuation value is usually expected. For measurements in the Rx band an amplifier is more
suitable so there are 2 possible values which are exclusively used for the same operation.

• External attenuation (negative value: gain) for all measurements outside the Rx band;

• Rx gain (gain) for all Rx-band measurements (negative value: attenuation).

and the set value is ignored.
