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
moved from a cold to a warm environment.

1 Preparation for Use
1.1 Putting into Operation
Before putting the SME into operation, please make sure that
• the covers of the casing are put on and screwed,
• the ventilation openings are free,
• no signal voltage levels exceeding the permissible limits are applied at the inputs,,
• the outputs of the instrument are not overloaded or connected incorrectly.
If these points are not observed, the instrument might be damaged.
1.1.1 Supply Voltage
The SME can be operated at a.c. systems f rom 90 to 132 V and 180 to 265 V at system frequencies
from 47 to 440 Hz. The power supply socket is s ituated at the rear of the instrument. The instrum ent
automatically sets itself to the voltage applied within the permissible voltage ranges. It is not necessary
to set the instrument to a certain supply voltage.
1.1.2 Switching On/Off the Instrument
Switch on/off: À Press power switch at the top/bottom
Power switch
Fuse holder

SME Putting into Operation
1.1.3 Initial Status
Upon switching on, the instrument either autom atically assumes the status which was s et when it was
switched off (param eter POW ER-ON ST ATE PREVIOUS SET TING in LEVEL-LEVEL m enu) or the RF
output is disconnected (POWER-ON STATE RF OFF).
If the instrument need not to be operated from the initial status any further, a defined default status
should be established by pressing the [PRESET] key prior to further settings.
STANDBY Mode
In the STANDBY mode the optional reference oscillator (option SM-B1) remains switched on, which
increases frequency accuracy.
Frequency accuracy after switching on when the oven-controlled reference oscillator is fitted
(option SM-B1)
When switching on from the STANDBY mode, the specified frequency accuracy is reached immediately.
If the power switch was switched off, the ref erence oscillator needs som e minutes of warm-up time to
reach its nominal frequency. During this period of time, the output frequency does not yet reach its final
value either. In the status line in the header field of the display the mess age "OVEN COLD" is displayed
for this time.
1.1.4 Setting Contrast and Brightness of the Display
Brightness control
Contra s t cont ro l
Contrast and brightness of the display can be set by means of the contrast and brightness controls
situated below the display.
1.1.5 RAM With Battery Back-Up
The SME has a static read-write memory (CMOS-RAM) with battery back-up, in which 50 different
complete settings of the instrument can be stored (cf. Chapter 2, section "Storing and Calling of
Instrument Settings"). In addition, all data and/or lists the user enters himself, such as for list m ode,
memory sequence, user correction of the level and data sequences with digital m odulation, ar e s tored in
the RAM. Further, all data of the calibrations running within the instrum ent in the SME are stor ed in the
RAM (cf. Chapter 2, section "Calibration").
A lithium battery with a service life of approx. 5 years serves to s upply the RAM with power. When the
battery is discharged, the data stored will be lost. Exchanging the battery is described in Chapter 4.

All parameters and circuit states, even those of operating modes which are not activated, are preset by
means of Preset.
The presettings going beyond the above list can be seen from the menu repr esentations as of Section
2.4 which each indicate the Preset setting status.
1.2 Functional Test
On switching on the instrument and perm anently during operation, the SME carries out a self test. T he
ROM contents as well as the battery of the non-volatile RAM are checked on switching on the
instrument and the RAM contents with every calling the memory. The most important instrument
functions are automatically monitored during operation.
If an error is detected, the m essage "ERROR" is displayed in the status line. For further identification of
the error, press the [ERROR] k ey. Thereupon a description of the err or/s is displayed (cf. Chapter 2,
section "Error Messages"). Return to the menu exited by pressing the [RETURN] key.
If required, the self tests can be induced purposefully. See Chapter 4, section "Functional Test".
Further, internal test points can be polled by the user and the results be read out and displayed. See
Chapter 2, section "Voltage Indication of Test Points".

SME Fitting the Options
1.3 Fitting the Options
Due to its variety of options, the SME offers the possibility of providing the instrument with the
equipment exactly corresponding to the application. Newly fitted options are automatically recognized
and the relevant parameters added in the menu.
After every change of the instrument conf iguration, the CMOS RAM has to be cleared as the storage
data shift:
À Switch off the instrument
À Switch the instrument on again with the [RESET] key pressed
The internal calibration routines PULSE GEN, YFOM, ALLAMP now have to be called up again to
restore the cleared calibration values.
These routines are accessible via m enu UTILITIES-CALIB (see also Chapter 2, section "calibr ation").
The calibration routines have to be carried out in the following order:
1. YFOM
2. ALLAMP
3. PULSE GEN (if installed)
1.3.1 Opening the Casing
Remove paneling À Remove four screws in the two tilt feet at the rear of the instrument.
À Remove the upper paneling towards the top and rear.
À Turn the instrument.
À Remove the lower paneling towards the top and rear.
Open ventilation ducts
When an option is fitted at a slot which has not been used up to now,
the appropriate ventilation duct of the plexiglas plate at the lef t in the
casing frame must be opened. T he openings are pre-punched so that
the respective part is easy to break out.

Fitting the option À Fasten the option at the back end of the lateral opening by means of
the screw threads provided there.
À If slots A5 and A6 are both occupied, one of these modules m ust be
removed temporarily.
À Feed ribbon cable W710 through the rear square cut-out to the
motherboard, insert into connector X22 and snap in the locking.
À Feed coaxial cable W 710 from socket X711 of the option through
the second cut-out along the rear transverse panel to connector
X74 at the A7 module, reference/step synthesis, via the
motherboard and insert there. Fasten the cable at the transverse
panel using the cable ties attached.
Set tuning voltage and calibrate
OCXO
The crystal oscillator was factory-tuned to nominal frequency and the
appropriate tuning voltage indicated on the cover of the m odule. The
calibration value now has to be calculated from this value and
transferred to the memory of the signal generator.
1038.6002.02 1.5 E-13
SME Fitting the Options
Calculate calibration value The tuning voltage is generated by a 12b-bit-D/A converter which is
scaled such that a tuning voltage of 12 volts is generated with
calibration value (CALIBRATION DATA) 4000.
The calibration value is thus calc ulated from the tuning voltage (V
as follows
CALIBRATION DATA = V
For checking purposes, the voltage at pin 16 of plug X22 on the
motherboard can be rem easured and corrected if necessary. A check
by means of frequency measurement may only be made after a
warm-up of 2 hours and against a calibrated reference.

)
Store calibration value
À Call menu UTILITIES-CALIB-REF OSC.
À Enter the calculated calibration voltage with CALIBRATION DATA
by means of the rotary knob or keypad.
À Select STORE CALIBRATION DATA
À Terminate entry using the [SELECT] key
The new calibration value is stored in the EPROM.
Note: The flash EPROM does not permit the deletion of individual
data. Thus new memory space is occupied for each calibration.
If there is no memory space available any more, the EPROM
must be cleared by an authorized service shop and be written
into anew. Thus a calibration should only be made if necessary
1.3.4 Option SM-B2 - LF Generator
Fitting as 1st generator As 1st generator , the LF generator is f itted at one of the rear slots A5,
A6 or A12.
À Withdraw jumper X29 at the front top of the motherboard.
À Plug jumper X3 at position 2-3 ( on the right) on the option (to the
right of multipoint connector X50).
Fitting as 2nd generator If ther e already is a generator at one of the s lots A5, A6 or A12, the LF
generator is mounted at slot A4.
À Withdraw jumper X28 on the motherboard.

2.2.2 Basic Operating Steps
The operating principle is explained in this section. For better understanding, please read sections
"Display" (Section 2.2.1) and "Sample Setting for First Users" (Section 2.2.3) in addition.
To operate the instrument, menus are called in the display. All setting possibilities and the current
setting status are evident from the menus. All settings can be made by accessing the menus.
RF frequency and RF level can also be set without m enu operation using keys [FREQ] and [LEVEL].
RF signal and modulation can also be switched on/off without menu operation us ing keys [RF ON/OFF]
and/or [MOD ON/OFF].
2.2.3.1 Calling the Menus
Accessing the menus is effected using rotary knob [VARIATION], [SELECT] key and [RETURN] key.
Rotary knob
Rotary knob [VARIATION] moves the menu cursor over the positions of a menu level
to be selected.
If a scrollbar is visible at the left-hand mar gin of a m enu, the menu is larger than the
screen window. If the menu cursor is moved to the m argin of the scr een window, the
covered lines become visible.
[SELECT] key
[RETURN] key
The [SELECT acknowledges the selection marked by means of the menu cursor.
The [RETURN] key
- returns the menu cursor to the next higher menu level.
The menu cursor is shifted to the left into the preceding column of the menu
structure.
- resets the menu cursor from frequenc y or level value indication in the header field
into the menu field to the menu called last.
- closes the display pages called using keys [STATUS], [HELP] and [ERROR]
again.
Settings are accessed in the setting menus ending with the right-hand display margin.

2.2.4 List Editor
The SME offers the possibility to generate lists. Lists are used for setting sequences (LIST m ode or
memory sequence), as data s ource for digital m odulations or for level correc tion which can be defined
by the user (UCOR). They consist of elements which are defined by an index and at least one
parameter per index. Each list is marked by a separate name and c an be selected via this name. T he
lists are accessed in the menus ass igned in each case, e.g. to the s ettings sequenc es of fr equency and
level value pairs in the LIST menu. However, the lists are always generated and processed in the same
way and the procedures are hence explained in detail by the example of the mem ory sequence mode
(menu MEM SEQ) in this sec tion. A pattern setting at the end of this section allows the us er to bec ome
familiar with the operation of the list editor.
Setting menus providing list processing are structured in two pages:
The first page, called OPERAT ION page in the following contains the general conf iguration param eters
for processing a list. Further , the general list functions s uch as selecting and deleting the list as well as
calling an editing mode are provided. The second page, the EDIT page, is autom atically displayed when
calling an edit function and serves to enter and modify the parameters of the list.
The OPERATION page has a sim ilar arrangem ent with all list editors. As an exam ple, the OPERAT ION

2.4.1 Frequency Offset
The SME offers the poss ibility of entering an offset ( OFFSET ) of poss ibly series-connected instr uments
in the FREQUENCY menu. The indication/input value of FREQ in the header field cons iders this input
and represents the frequency value of the RF signal at the output of these instruments (cf. Fig. 2-17).
The entry values FREQUENCY and OFFSET in the menu FREQUENCY or FREQ in the header line are
related to the RF output frequency as follows :
FREQ - OFFSET = output frequency (= FREQUENCY).
An offset entry causes no modification of the RF output frequency but only a modification of the display
value in the FREQ field in the header line, ie FREQ in the header line indicates the offset-associated
frequency and FREQUENCY in the menu FREQUENCY the RF output frequency. The status line
indicates FREQ-OFFST.
The offset setting also remains effective with the frequency sweep.

2.5 RF Level
The RF output level can be set directly using the [LEVEL] key (cf . Section 2.2.2.5) or by accessing the
LEVEL menu.
In the LEVEL-LEVEL menu, the set RF output level is indicated under AMPLITUDE. A two-line level
display appears for digital modulation or digital standar d. The upper line indicates the average power
(LEVEL), the lower line the peak envelope power (PEP) of the modulated RF output signal.
The input value of level settings effected in the LEVEL-LEVEL menu directly corresponds to the RF
output level.
The input value of the level settings opened using the [LEVEL] key mathematic ally considers the offset
of an attenuation/amplification element which is possibly series-connected (cf. Section 2.5.1). This offers
the possibility of entering the desired level at the output of series-connected instruments, the SMIQ then
alters the RF output level correspondingly. The offset can also be entered in the LEVEL-LEVEL menu.
dBm, dBµV, mV and µV can be used as level units. T he 4 unit keys are directly labeled with these units .
In order to change to another level unit, simply press the desired unit key.
Notes: - The mes sage ERROR is displayed in the status line if the level s et in the overrange is
not reached.
- For digital modulation or digital standard, a WARNING message appears in the status
line if the set LEVEL or the displayed PEP are overranged. If the set level cannot be

The entry values AMPLITUDE and OFFSET in the menu LEVEL or LEVEL in the header line are related
to the RF output level as follows:
LEVEL - OFFSET = output level (= AMPLITUDE)
An offset entry causes no modification of the RF output frequency but only a modification of the display

Menu LEVEL-ALC offers access to settings for level control.
Level control can be deactivated and various bandwidths of the level control can be switched on.
Switching off level control (ALC STATE OFF) switches over the internal level control into a
sample-and-hold operation. In this operating mode, level contro l is automatic ally switched on for a short
period of time after every level and frequency setting, and then the level control is held at the value
achieved. Switching off the level control is us ed with multi-transmitter measurements to ac hieve a lar ger
intermodulation ratio.
Bandwidth setting influences the AM noise of the output signal. The bandwidth of the level control has
the same effect as a filter of the same bandwidth.

2.5.5 User Correction (UCOR)
Function "User Correction" can be used to create and activate lists in which arbitrary RF frequencies ar e
assigned level correction values.
Up to 10 lists with a total of 160 correction values can be compiled. For frequencies which are not
included in the list the level correction is determined by means of interpolation of the nearest correc tion
values.
When user corr ection is switched on, the LEVEL indication is com pleted by the indication UCOR (User
Correction) in the header field of the display. The RF output level is the sum of both values.
LEVEL + UCOR = output level
If the offset setting is used at the same time, the LEVEL indication value is the diff erence of the input

2.6.1 Modulation Sources
Internal Modulation Sources
Internal modulation generators LF GEN1 and LF GEN2 are available for AM, FM and PM depending on
the equipment. For a more detailed description, cf. Section 2.6.2.1, LF Generator.
For internal pulse modulation, the instrument can be equipped with a pulse generator (option SM-B4) .
For a more detailed description, cf. Section 2.6.2.5.1, Pulse Generator.
A PRBS generator with selectable sequence lengths and a data generator are available for the digital
modulations (cf. Section 2.6.3, Digital Modulation).
External Modulation Sources
The appropriate input sockets to the dif ferent modulations in the case of external supply can be taken
from table 2-1. DM (digital modulation) stands for GMSK, GFSK, QPSK, FSK, FFSK and 4FSK. External
AM, FM and PM can be AC or DC-coupled.

SME Modulation Sources
The external modulation signal must show a voltage of V
= 1 V (V
s
= 0.707 V) in order to maintain the
eff
modulation depth or deviation indicated. Deviations of more than ±3 % are signaled in the status line by
means of the following messages (cf. table 2-2).
Table 2-2 Status messages in the case of a deviation from the rated value at the external modulation
input
Message Deviation
EXT1-HIGH Voltage at EXT1 too high
EXT1-LOW Voltage at EXT1 too low
EXT2-HIGH Voltage at EXT2 too high
EXT2-LOW Voltage at EXT2 too low
EXT-HI/HI Vol tage at EXT1 and EXT2 too high
EXT-LO/LO Voltage at EXT1 and EXT2 too low
EXT-HI/LO Volt age at EXT1 too high and EXT2 too low
EXT-LO/HI Voltage at E XT1 too low and EXT2 too high
2.6.1.1 Simultaneous Modulation
Basically, every combination of AM, FM, pulse modulation and a digital modulation (GMSK, GFSK,
QPSK, FSK, FFSK or 4FSK) is possible. Instead of FM, phase m odulation (PM) can be switched on as
well. There are only restrictions for modulations of the same k ind and for the multiple use of the 2nd LF
generator (cf. table 2-3).
Two-tone AM is possible by simultaneously switching on the external and internal source.
Two-tone FM or two-tone PM is possible by simultaneously switching on FM1 and FM2 or PM1 and
PM2. For FM1 and FM2 (PM1 and PM2) separate deviations can be set and separate sources switched
on.
Note: With two-tone modulation please observe that the set dev iation or modulation depth is valid for
one signal and the sum deviation or sum modulation depth is determined by adding both
signals. This results in overmodulation if the max imal value for deviation or modulation depth is
exceeded.
2.6.1.2 Alternate Switching Off of Modulations
Due to the multiple use of som e functional modules in the instrument som e modulations cannot be set
at the same time (c f. table 2- 3). In the case of m anual control, incom patible m odulations deactivate one
another, a short-time warning is displayed in the status line.
Note: The IEC-bus control according to SCPI forbids the mutual influence of types of modulation on
one another. In the case of remote control, an error mes sage is outputted when the attempt is
made to switch on incompatible types of modulation (cf. annex B).

2.6.1.3 [MOD ON/OFF] Key
The modulations can directly be switched on/off using the key [MOD ON/OFF] or by accessing the
MODULATION menu. When switching on using the [MOD O N/OFF] key, the m odulation s ources which
are set in the modulation menus are used.
The [MOD ON/OFF] key can either be effec tive for all modulations or for a selected m odulation. The
selection for which modulation the [MOD ON/OFF] k ey is effective is m ade in the UT ILITIES- MOD KEY
menu (cf. Section " Assigning Modulation to [MOD ON/OFF] Key").
When selecting a certain type of modulation, each press ing the [MOD ON/OFF] key switches on or off
the modulation selected.
In the case of selection "all modulations", the [MOD ON/OFF] key has the following effect:
• At least one modulation is active:
Pressing the [MOD ON/OFF] key switches off all active modulations. Which modulations were active
is stored.
• No modulation is active:
Pressing the [MOD ON/OFF] key switches on the modulations which were last switched off using the
[MOD ON/OFF] key.

2.6.2 Analog Modulation
2.6.2.1 LF-Generator
The SME is equipped with a fixed-frequency generator as internal modulation source as a standard. The
generator supplies sinusoidal signals of the frequencies of 0.4, 1, 3 and 15 kHz.
In addition to the standard equipment, the SME can be equipped with the following optional
LF modulation sources:
• LF-generator, option SM-B2
• Multifunction generator, option SM-B6
It is possible to fit two optional modulation sources unless option SM-B3, pulse modulator, is fitted. If two
options are fitted, the access to the internal s tandard generator is eliminated. T he different pos sibilities
of modulation generator fitting are visible from table 2-4:
