sea level.
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
1171.0000.42-03.00
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.
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/operator 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

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.
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
(corresponding to the 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.
Never use the product if the power cable is
damaged. Check the power cable on a
regular basis to ensure that it is in proper
operating condition. 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.
The product may be operated only from
TN/TT supply networks fused with max.
16 A (higher fuse only after consulting with
the Rohde & Schwarz group of companies).
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.
Do not overload any sockets, extension
cords or connector strips; doing so can
cause fire or electric shocks.
For measurements in circuits with voltages
Vrms > 30 V, suitable measures (e.g.
appropriate measuring equipment, fusing,
current limiting, electrical separation,
insulation) should be taken to avoid any
hazards.
Ensure that the connections with
information technology equipment comply
with IEC 950/EN 60950.
Unless expressly permitted, never remove
the cover or any part of the housing while
the product is in operation. Doing so will
expose circuits and components and can
lead to injuries, fire or damage to the
product.

Putting into Operation
This chapter contains all information about putting into operation (unpacking, connection to AC supply,
switching on and off), functional testing and installation of the instrument, preset settings and views of
the front and rear panel showing the controls and connectors needed for operation.
General Instructions
Before putting the R&S SML / R&S SMV03 into operation, please make sure that
•
•
•
•
the cover 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.
Unpacking the Instrument
Take the instrument out of the shipping box and check whether the
items listed in the packing list and in the lists of accessories are all
included.
remove protective cabs
Remove the two protective caps from the front and rear of the
instrument and carefully check the instrument for damage.
Should the instrument be damaged, immediately notify the forwarder who shipped the instrument to you
and keep the box and packing material.
For further transport or shipment of the instrument the original packing should also be used. It is
recommended to keep at least the two protective caps for front and rear side in order to prevent
damage to the controls and connectors.

Putting into Operation
R&S SML / R&S SMV03
Setting up the Instrument
For applications in the laboratory or on a work bench, it is recommended that the support feet on the
bottom of the instrument be extended. For the LCD display, this provides the optimum viewing angle
which typically ranges from perpendicular to the display front to approximately 30° below.
Warning
Danger of injury
The feet may fold in if they are not folded out completely or if the instrument is
shifted. The feet may break if they are overloaded.
Fold the feet completely in or completely out to ensure stability of the instrument and
personal safety.
To avoid injuries, never shift the instrument when its feet are folded out.
The overall load (the instrument's own weight plus that of the instruments stacked on
top of it) on the folded-out feet must not exceed 500 N.
Place the instrument on a stable surface. Secure the instruments stacked on top of it
against slipping (e.g. by locking their feet on the top front frame).
When the instrument is standing on its folded-out feet, do not work under the
instrument and do not put anything under it, otherwise injuries or material damage
could occur.
The instrument can be used in each of the positions shown here.
Cleaning the Outside and Storing
What is necessary is essentially the cleaning of the instrument.
ATTENTION
1090.3123.12
Instrument damage caused by cleaning agents!
Cleaning agents contain substances that may damage the instrument, e.g. solventcontaining cleaning agents may damage the front panel labeling or plastic parts.
Never use cleaning agents such as solvents (thinners, acetone, etc), acids, bases, or
other substances.
The outside of the instrument is suitably cleaned using a soft, line-free dust cloth.

Putting into Operation
Supply Voltage
The R&S SML / R&S SMV03 can be operated at a.c. systems from 100 to 120 V and 200 to 240 V at
system frequencies from 50 to 60 Hz. The power supply socket is situated at the rear of the instrument.
The instrument 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.
How to Ensure EMC
In order to avoid electromagnetic interference, the instrument may only be operated when it is closed
and with all shielding covers fitted. Only appropriate shielded signal and control cables may be used.
Power Fuses
The R&S SML / R&S SMV03 is protected against short circuits by means of two fuses according to
nameplate of the power supply. The fuses are situated in the draw-out fuse holder which is inserted
close to the power supply socket (see below).

Initial Status
Upon switching on, the instrument automatically assumes the status which was set when it was
switched 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] and [SELECT] keys prior to further settings.
Frequency accuracy after switching on when the oven-controlled reference oscillator is fitted
(option R&S SML-B1)
The reference oscillator needs some 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 message "OVEN COLD" is displayed for this time.

RAM With Battery Back-Up
The R&S SML / R&S SMV03 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 3, section "Storing and Calling of
Instrument Settings"). In addition, all data and/or lists the user enters himself, such as for user correction of the
level, are stored in the RAM. Further, all data of the calibrations running within the instrument in the R&S SML
/ R&S SMV03 are stored in the RAM (cf. Chapter 4, section "Calibration"). A lithium battery with a service life
of approx. 5 years serves to supply the RAM with power. When the battery is discharged, the data stored will
be lost. Exchanging the battery is described in the Service Manual.
Preset Setting
A defined setting status is achieved by pressing the [PRESET] key.

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
representations as of Chapter 4 which each indicate the Preset setting status.
Functional Test
On switching on the instrument and permanently during operation, the R&S SML / R&S SMV03 carries
out a self test. The ROM contents as well as the battery of the non-volatile RAM are checked. The most
important instrument functions are automatically monitored during operation.
If an error is detected, the message "Err" is displayed in the status line. For further identification of the
error, press the [ERROR] key. Thereupon a description of the error is displayed (cf. Chapter 9, section
"Error Messages"). Return to the menu exited by pressing the [BACK] key.
If required, internal test points can be polled by the user and the results be read out and displayed, cf.
Service Manual.
Mounting into a 19" Rack
The R&S SML / R&S SMV03 can be mounted into a 19" rack by means of rack adapter ZZA-211 (stock
no. 1096.3260.00). The mounting instructions are attached to the adapter.
ATTENTION
1090.3123.12

Design of the Display
Manual Operation
This chapter shows the design of the display and describes the manual control of the signal generator,
for example calling up of menus, selection and editing of parameters, use of the list editor and the
SAVE/RECALL function. This chapter also contains an overview of menus showing the functions
available for the instruments and its options.
It is useful to read the sample settings for first users in Chapter 2, "Short Tutorial".
Design of the Display
(1)
(2)
(3)
Fig. 3-1
Design of the display
(1) Header field
The header field of the display indicates frequency and level of the RF output
signal. In the RF-sweep operating mode, the start and stop frequencies are
displayed in two lines one above the other. The start and stop levels are indicated in
the LEVEL-sweep operating mode correspondingly.
(2) Status line
The status line indicates at the left the menu path of the current menu and at the
right the operating mode and operating state of the instrument. Error messages and
notes for caution are also displayed in the status line.
(3) Menu fields
The indication fields below the status line are reserved for the menu
representations. The image contents of these fields change as a function of the
menu selected.
The lowest menu level shows the setting menu with the current settings of the
selected menu. Settings are made in select or input windows which open when the
current setting is activated.
Menu cursor
Digit cursor
1090.3123.12
The menu cursor shows the user at which position in the menu he
is. The position of the menu cursor is evident from the inverse
notation of the term (white characters on a black background).
As a bright field, the digit cursor marks the position which can be
varied by means of the rotary knob in a value indication.
3.1
E-6
Basic Operating Steps
R&S®SML / R&S®SMV03
Basic Operating Steps
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 menu operation using keys [FREQ] and [LEVEL].
RF signal and modulation can also be switched on/off without menu operation using keys [RF ON/OFF]
and/or [MOD ON/OFF].
Calling the menus
Accessing the menus is effected using rotary knob [VARIATION], [SELECT] key and [BACK] 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 right-hand margin of a menu, the menu is larger than
the screen window. If the menu cursor is moved to the margin of the screen window,
the covered lines become visible.
If the rotary knob is pressed after a position has been selected, the lower menu level
or the respective settings are called. The rotary knob hence has the same function
as the [SELECT] key.
[SELECT] key
The [SELECT] key acknowledges the selection marked by means of the menu
cursor. Depending on the position, the next lower menu level or the the respective
setting is called.
[BACK] key
The [BACK] 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 frequency 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.

1090.3123.12
RF frequency and RF level can also be varied in a step width
which can be defined arbitrarily, using the rotary knob. In the
respective setting menu (Frequency or Level), the step width is
entered as Knob Step User and the Knob Step set from Decimal
to User. To point to the fact that the step width has been
converted to the value programmed, the bright field as a symbol
of the digit cursor disappears in the respective value indication.

RF Frequency
Instrument Functions
This chapter describes the functions of the instrument and its options which can be activated manually
via menus or by remote control (frequency and level settings, analog modulations, sweep, and general
functions not directly related to signal generation).
RF Frequency
The RF frequency can be set directly using the [FREQ] key or via the Frequency menu. In the
Frequency menu, the frequency of the RF output signal is entered and indicated under Frequency.
In frequency settings made with the [FREQ] key, an arithmetic offset is taken into account. Such
settings are indicated in the header line of the display. This makes it possible to enter the desired output
frequency of subsequent units, if any (eg mixers). The offset can also be entered in the Frequency
menu (see next section: "Frequency Offset").

Frequency Offset
On the R&S SML / R&S SMV03 it is possible to enter an offset for subsequent units, if any, in the
Frequency menu. Such entries are taken into account in the frequency displayed in the header line,
which indicates the frequency of the RF signal at the output of the units in question (see Fig. 4-2).
The frequency of the RF output signal in the Frequency menu is calculated from the frequency displayed
in the header line and offset values as follows:
RF output frequency = frequency displayed in header line – offset
The entry of an offset causes a change of the frequency value displayed in the header line (the value
taking into account the offset is displayed). The value of the RF output frequency is displayed under
Frequency in the Frequency menu.
The entered offset remains active also for frequency sweeps.

Typical setups with frequency offset
Extended Divider Range
For frequencies of equal or greater than 77 MHz, the R&S SML / R&S SMV03 generates the RF signals
by means of frequency division or frequency multiplication. Below 77 MHZ the RF signals are normally
generated by frequency mixing. This results in good modulation capabilities but reduced single-side
phase noise. (see fig. "Typical SSB phase noise versus carrier frequency" in the datasheet). When the
extended divider range is activated excellent single-sideband phase noise values will be obtained in the
frequency range from approximately 9.5 MHz to 77 MHz but all other specifications of the R&S SML /
R&S SMV03 cannot be guaranteed for this operation mode.

RF Level
RF Level
The RF level can be set directly using the [LEVEL] key or via the Level - Level menu.
In the Level - Level menu, the set RF output level is entered and indicated under Amplitude.
In level settings made with the [LEVEL] key, the offset of a subsequent attenuator/amplifier is taken into
account (see section "Level Offset"). This makes it possible to enter the desired level at the output of
subsequent units. The offset can also be entered in the Level - Level menu under Offset.
dBm, dBFV, mV and FV can be used as level units. The four unit keys are labelled with the respective
units. To change to another level unit, simply press the corresponding unit key.

Level Offset
On the R&S SML / R&S SMV03, it is possible to enter an offset for a subsequent attenuator/amplifier, if
any, in the Level menu. The offset is taken into account in the display in the header line (see below),
which represents the level value of the signal at the output of the subsequent unit (see Fig. 4-4).
The level of the RF output signal is therefore calculated from the amplitude displayed in the header line
and the offset entered in the Level - Level menu as follows:
RF output level = amplitude displayed in the header line – offset
The entered offset has no influence on the RF output signal of the R&S SML / R&S SMV03; the offset is
only taken into account in the displayed level value. The value with the offset can be directly entered
with the [LEVEL] key.
The RF output level of the R&S SML / R&S SMV03 is indicated in the Level - Level menu.

Non-Interrupting Level Setting
With Attenuator Mode Fixed, non-interrupting level setting is performed. Level settings are made
electronically only in a 20-dB range downwards from switching level with fixed attenuator.
(Full “Fix”Range 28/30-dB overrange aprox.)
Note:
Level accuracy and spectral purity are not guaranteed over the full “Fix”Range.
If the level falls below the permissible variation range, the warning "Level underrange" is output in the
status line of the display; if it attains or goes beyond the upper limit value, the warning "Level overrange"
or “Unleveled” is output.
Please note limit and/or other limiting factors.

Modulation - General
Modulation - General
The R&S SML / R&S SMV03 offers the following modulation types :
• Amplitude modulation (AM),
• Frequency modulation (FM),
• Phase modulation ( M),
• Pulse modulation PULSE (Option R&S SML-B3),
• Stereo modulation STEREO (Option R&S SML-B5),
• Vector modulation VECTOR (R&S SMV03 only),
For all modulations except vector modulation an internal or external modulation source can be used. For
stereo modulation external analog R or L signals can be applied. The operation modes R, L, R=L, R=-L
and R L are available. In addition the R&S SML / R&S SMV03 provides an S/P DIF input for externally
generated digital stereo signals. Vector modulation requires external modulation signals.
Modulation Sources
Internal modulation source
For AM and FM/ M, an internal modulation generator (Lfgen) is available. For more information see
section "LF Generator". ". The generator can also be used for analog stereo modulation. In this case the
operation modes R, L, R=L, R=-L are available. For more information see section "Stereo Modulation
(option R&S SML-B5)".
For internal pulse modulation (option R&S SML-B3), the instrument is equipped with a pulse generator.
For more information see section "Pulse Generator".
External modulation source for AM, FM/!M) and PULSE
For external modulation, input connectors MOD (AM, FM/ M) and PULSE (Pulse modualtion) are
available. External AM and FM/ M can be AC- or DC-coupled.
External modulation signals should have a voltage of Vp = 1 V (Vrms = 0.707 V) to maintain the
displayed modulation depth or deviation.
External modulation sources for stereo modulation
For external analog stereo modulation, input connectors STEREO R and STEREO L are available at the
rear panel of the R&S SML / R&S SMV03 .
External modulation signals should have a voltage of Vp = 1 V (Vrms = 0.707 V) to maintain the
displayed frequency deviation.
For external digital stereo modulation the unsymmetrical BNC input connector S/P DIF is available (input
impedance of 75 ). The external modulation signal should have a voltage of Vpp = 400 mV to Vpp = 5 V.

E-6
Modulation - General
R&S®SML / R&S®SMV03
Extrenal modulation sources for vector modulation
For external vector modulation, input connectors I and Q are available at the rear panel of the SMV03
(input impedances 50 ). To avoid the I/Q modulator being overdriven the input voltage should never
2
2
exceed I + Q = 0.5 V.
Simultaneous Modulation
If vector modulation is deactivated then basically any combination of AM, FM/ M/stereo and pulse
modulation is possible. There are restrictions only for FM, M. and stereo. The same is true for activated
vector modulation. Though, then there is an additional restriction for AM.
Two-tone AM and two-tone FM/ M can be selected via menu (Modulation - AM (FM/ M) - AM (FM/ M)
Source - Two Tone).
Mutual Switch-Off of Modulation Types
As FM, M and stereo use the same modulator, they cannot be activated simultaneously. They
deactivate one another. In a similar way the same is true for AM and vector modulation. For AM the
level control has to be activated while vector modulation requires the level control being deactivated.
Note:
IEC/IEEE-bus control according to SCPI does not allow the selection of the incompatible
modulation types FM, M and stereo. With remote control, an error message is output
when an attempt is made to activate these types of modulation (see Chapter 9).
[MOD ON/OFF] Key
The various types of modulation can be switched on and off directly using the [MOD ON/OFF] key or via
the Modulation menu. If switch-on is made using the [MOD ON/OFF] key, the modulation sources which
are set in the modulation menus are used.
The [MOD ON/OFF] key can be effective either for all types of modulation or only for a selected
modulation. The selection of modulation types for which the [MOD ON/OFF] key is to be effective is
made in the Utilities – Mod Key menu.
If only one type of modulation is selected, it is switched on or off each time the [MOD ON/OFF] key is
pressed.
If all modulation types are selected, the [MOD ON/OFF] key has the following effect:
• If at least one modulation type is active:
Pressing the [MOD ON/OFF] key switches off all active modulation types. The modulation types
which were active are stored.
• If no modulation type is active:
Pressing the [MOD ON/OFF] key switches on the modulation types that were last switched off with
this key.

R&S®SML / R&S®SMV03
Pulse Modulation (Option R&S SML-B3)
The pulse modulator can be controlled from an external source or by an internal pulse generator. With
external control, the external source feeds the pulse modulator directly. The envelope of the RF is
identical to the control signal. With control by the internal pulse generator, the pulse shape of the pulse
generator determines the envelope of the RF. The pulse delay, pulse width and pulse period can be set.

Pulse Generator
As an internal modulation source, the pulse generator offers the possibility of setting single and double
pulses with variable pulse delay, pulse width and pulse period. The pulse generator can be triggered
internally or by an external signal at the PULSE input. The following Pulse modi can be selected: Auto
Trig, Ext Trig, and Ext Gated (see Fig. 4-13 to Fig. 4-15). The internal trigger signal is derived from the
reference frequency and hence very stable. In the trigger mode Ext Trig, the positive or the negative
edge can be used for triggering the pulse generator. In the trigger mode Ext Gated, the pulse generator
is triggered as long as an active Gate signal arrives at the PULSE input.
The pulse generator can also be used as an independent unit, ie without the pulse modulator being
controlled if the pulse modulation source (Pulse Source) is switched to OFF or EXT. The pulse can be
tapped at the VIDEO output.

Command:
MASK=xx,yy,aaaaaaa,bbbbbbb,ccccccc,dddddddd
Query:
MASK?
Response:
xx,yy,aaaaaaa,bbbbbbb,ccccccc,dddddddd
Value range:
xx = 00 to FF (hexadecimal values), corresponding to number of groups to be
masked.
If xx is set to zero, the RDS groups are continuously linked to the error mask.
If xx is set to a value other than zero, this value is decremented after each
errored group transmitted. When zero count is reached, no further errored groups
are transmitted, and MASK_STATE is set to "0".
yy = 00 to FF (hexadecimal values)
Number of error-free groups to be inserted after each errored group
a, b, c d = 0000000 … 3FFFFFFF,
Hexadecimal bit mask for blocks A, B, C and D of the RDS groups.For each
block, 26 bits (16 data bits and 10 CRC bits) have to be entered in hexadecimal
code.
Example:
Command:
STEReo:DIRect “MASK=09,01,0000001,0000000,0000000,0000000“
In nine RDS groups, the least significant bit of the CRC code of block A is
inverted, i.e. an errored bit is sent. After each errored group, one error-free group
is inserted. After transmission of the complete sequence, MASK_STATE is set to
"0".
With the command MASK_STATE=1, the above sequence (9 errored groups with
one error-free group inserted after each errored group) is retransmitted once.
Then, MASK_STATE is again set to "0".
Query:
STEReo:DIRect? “MASK“
Response:
"09,01,0000001,0000000,0000000,0000000"

Alternative Frequency Lists
Alternative frequency lists can be transmitted in two ways:
Method A:
The frequencies of an AF list are entered one after the other; the frequency currently
transmitted has to be specified as the first frequency.
Method B:
The frequencies of an AF list are entered in pairs, each pair containing the frequency
currently transmitted and an alternative frequency. The frequency pairs should normally be
entered in ascending order. Descending order should be chosen only if the alternative
frequencies belong to different regions or are used to broadcast different programs at
different times.
Note:
Do not combine methods A and B!
Method A:
Generate a new alternative frequency list with
STEReo:DIRect “AF=N,87.6,87.7,87.8“.
Set the group sequence, e.g.
STEReo:DIRect "gs=0A,14A".
The group sequence must contain group 0A.
The alternative frequencies are now transmitted in group 0A.
Add another alternative frequency list with
STEReo:DIRect “AF=+,88.6,88.7,88.8“
Method B
Generate a new alternative frequency list with
STEReo:DIRect “AF=N,87.6,90.2,87.6,90.2“.
Set the group sequence, e.g.
STEReo:DIRect "gs=0A,14A".
The group sequence must contain group 0A
he alternative frequencies are now transmitted in group 0A.
Add another alternative frequency list with
STEReo:DIRect “AF=+,88.6,91.2,88.6,91.2“
The frequency lists are not checked for correctness. For this reason, make sure that the syntax is
correct.
A maximum of five AF lists can be generated. For type A lists, max. 25 frequencies per list can be
specified, for type B lists, max. 12 frequencies per list.

Free Format Groups (FFGs)
In the user-definable groups 1A, 3A, 5A, 6A, 7A, 8A, 9A, 10A, 11A, 12A and 13A, any desired data can
be transmitted. Five bits of this data are transmitted in block B and 16 bits each in blocks C and D of the
specified group.
1. Define the data to be transmitted in group 1A:
STEReo:DIRect “1A=05,0000000000,1FFFFFFFFF“
Group 1A is now transmitted first with "0000000000" and then with "1FFFFFFFFF".
Each of the two data sequences is retransmitted five times, which is indicated by the information
"05".
2. Set the group sequence, e.g.:
STEReo:DIRect "gs=0a,1a"
The defined data is now transmitted in group 1A.
Max. 20 different data sequences can be defined.
Transparent-Mode
The transparent mode allows the user to transmit freely definable binary data instead of the standard
RDS data. Blocks A to D of the RDS groups are used. This means that standard RDS data will no
longer be transmitted when transparent data is set. The binary data will be sent even if it constitutes no
valid or meaningful RDS data. The transmission of standard RDS data will not be resumed until the
transparent data is deleted.
Delete the transparent data and switch back to standard RDS data transmission with:
STEReo:DIRect “TRANS=0“
Max. 20 different data sequences can be defined.

Example: vector modulation
If the I/Q modulator is driven by a constant sum vector modulation of I + Q = 0. 5V the actual RF
level corresponds to the displayed RF level. To avoid the I/Q modulator being overdriven, care should
be taken that the sum vector never exceeds 0.5 V when digital modulation modes with amplitude
modulation components such as QPSK are used. For full-scale input, the peak envelope power of the
modulated RF signal is thus equal to the indicated LEVEL. The average power is smaller. The difference
can be entered as an offset in the LEVEL menu.

The R&S SML /R&S SMV03 features digital, step-by-step sweep for the following parameters:
RF frequency
LF frequency
RF level
A sweep is set in four basic steps, which are demonstrated by the following example, ie the setting of a
frequency sweep:
1. Set sweep range (Start Freq and Stop Freq or Center Freq and Span).
2. Select linear or logarithmic sweep (Spacing).
3. Select step size (Step Lin or Step Log) and dwell time (Dwell).
4. Switch on sweep (Mode set to Auto, Single, Step, Ext Single or Ext Step).
Setting the Sweep Range (Start Freq, Stop Freq, Center Freq, Span)
The sweep range for RF sweeps can be entered in two ways. Either the Start Freq and Stop Freq are
entered or Center Freq and Span. Please note that the two parameter sets mutually affect each other as
follows:

Selecting Linear or Logarithmic Sweep (Spacing Lin, Log)
Linear or logarithmic sweep can be selected with Spacing. For RF and LF sweeps, both the linear and
logarithmic modes are selectable. For level sweeps, only the logarithmic mode is possible.
With logarithmic sweeps, the step size (Step) is equal to a constant fraction of the current setting. The
logarithmic step size for RF and LF sweeps is entered in % and for level sweeps in dB.
Operating Modes (Mode)
The following sweep modes are available:
Auto
Sweep from start point to stop point with automatic restart at start point. If another
sweep mode was active prior to selection of the auto mode, the sweep is continued

Remote Control – Basic Information
This chapter provides basic information on remote control, for example on the IEC/IEEE bus, RS-232-C
interface, interface and device messages, command processing, status reporting system, etc.
The instrument is equipped with an IEC/IEEE-bus interface according to standard IEC 625.1/IEEE 488.1
and a RS-232-C interface. The connectors are located at the rear of the instrument and permit to
connect a controller for remote control. The instrument supports the SCPI version 1994.0 (Standard
Commands for Programmable Instruments). The SCPI standard is based on standard IEEE 488.2 and
aims at the standardization of device-specific commands, error handling and the status registers.
For this section it is assumed that the user has basic knowledge of IEC/IEEE-bus programming and
operation of the controller. A description of the interface commands will be found in the relevant
manuals.
The requirements of the SCPI standard regarding command syntax, error handling and configuration of
the status registers are explained in detail in the respective sections. Tables provide a fast overview of
the bit assignment of the status registers. The tables are complemented by a comprehensive
description of the status registers.
A description of commands is given in chapter 6. Programming examples for the main functions will be
found in chapter 7.

Switchover to Remote Control
Switchover to Remote Control
On power-up, the instrument is always in the manual control mode ("LOCAL" state) and can be
operated via the front panel.
The instrument is switched to remote control ("REMOTE" state) as follows:
IEC/IEEE-bus:
when it receives an addressed command from the controller.
RS-232-C interface:
when it receives a carriage return (=0Dh) or a line feed (=0Ah) from
the controller.
During remote control, operation via the front panel is disabled. The instrument remains in the remote
state until it is reset to the manual state via the front panel or via the IEC/IEEE bus. Switching from
manual to remote control and vice versa does not affect the instrument settings.
Remote Control via IEC/IEEE Bus
Setting the Device Address
The IEC/IEEE-bus address of the instrument is factory-set to 28. It can be changed manually in the
Utilities - System - GPIB-Address menu or via the IEC/IEEE bus. Addresses 1 to 30 are permissible.
Manually:
Call Utilities - System - GPIB-Address menu.
Enter desired address.
Terminate input using the [1x/ENTER] key.
Via IEC/IEEE bus:

Messages
Messages
The messages transferred via the data lines of the IEC/IEEE bus can be divided into two groups:
– interfaces messages and
– device messages
No interface messages are defined for the RS-232-C interface.
Interface Messages
Interface messages are transferred on the data lines of the IEC/IEEE bus, the ATN control line being
active. They are used for communication between the controller and the instrument and can only be
sent by a controller which has the IEC/IEEE-bus control. Interface commands can be subdivided into
- universal commands and
- addressed commands
Universal commands act on all devices connected to the IEC/IEEE bus without previous addressing,
addressed commands only act on devices previously addressed as listeners. The interface messages
relevant to the instrument are listed in the section "Interface Messages" below.
Some control characters are defined for the control of the RS-232-C interface, see section "Interface
Functions".
Device Messages (Commands and Device Responses)
Device messages are transferred on the data lines of the IEC/IEEE bus, the ATN control line not being
active. ASCII code is used. The device messages are largely identical for the two interfaces (IEC/IEEE
bus and RS-232-C).
A distinction is made according to the direction in which device messages are sent on the IEC/IEEE bus:
– Commands
are messages the controller sends to the instrument.
They operate the device functions and request information.
Commands are subdivided according to two criteria:
1. According to the effect they have on the instrument:
Setting commands
cause instrument settings such as reset of the
instrument or setting the output level to 1 V.
Queries
cause data to be provided for output (queries) on the
IEC/IEEE bus, eg for device identification or polling of
the active input.
2. According to their definition in standard IEEE 488.2:
Common Commands are exactly defined as to their function and notation in
standard IEEE 488.2. They refer to functions such as
the management of the standardized status registers,
reset and selftest.
Device-specific
commands
refer to functions depending on the features of the
instrument such as frequency setting. A majority of
these commands has also been standardized by the
SCPI committee.
– Device responses are messages the instruments sends to the controller in reply to a query. They
may contain measurement results or information on the instrument status.
The structure and syntax of device messages are described in the following section.

Structure and Syntax of Device Messages
Introduction to SCPI
SCPI (Standard Commands for Programmable Instruments) describes a standard command set for
programming instruments, irrespective of the type of instrument or manufacturer. The objective of the
SCPI consortium is to standardize the device-specific commands to a large extent. For this purpose, a
model was developed which defines identical functions of a device or of different devices. Command
systems were generated which are assigned to these functions. Thus it is possible to address identical
functions with identical commands. The command systems are of a hierarchical structure. Fig. 5-1
illustrates this tree structure using a section of command system SOURce, which operates the signal
sources of the devices. The other examples concerning syntax and structure of the commands are
derived from this command system.
SCPI is based on standard IEEE 488.2, ie it uses the same basic syntax elements as well as the
common commands defined in this standard. Part of the syntax of the device responses is defined in
greater detail than in standard IEEE 488.2 (see section "Responses to Queries").
Structure of Commands
Commands consist of a header and, in most cases, one or several parameters. The header and the
parameters are separated by a "white space" (ASCII code 0 to 9, 11 to 32 decimal, eg a blank). Headers
may consist of several key words. Queries are formed by appending a question mark directly to the
header.
Note:
The commands used in the following examples are not in every case implemented in the
instrument.
Common commands
Common (device-independent) commands consist of a header
preceded by an asterisk "*" and of one or several parameters, if any.
Examples:
Device-specific commands
Hierarchy:
*RST
RESET, resets the instrument
*ESE 253 EVENT STATUS ENABLE, sets the bits of
the event status enable register
*ESR?
EVENT STATUS QUERY, queries the
contents of the event status register
The following examples are general, they are not necessarly available
with R&S SML / R&S SMV03.
Device-specific commands are of a hierarchical structure (see Fig. 5-1).
The different levels are represented by combined headers. Headers of
the highest level (root level) have only one key word. This key word
denotes a complete command system.
Example:
SOURce
This key word denotes the SOURce command system.
For commands of lower levels, the complete path has to be specified,
starting on the left with the highest level, the individual key words being
separated by a colon ":".
Example:
SOURce:FM:EXTernal:COUPling AC
This command is at the fourth level of the SOURce system. It selects
AC coupling of the external signal source.

Tree structure of SCPI command systems using the SOURce system as an example
Some key words occur at several levels within one command system.
Their effect depends on the structure of the command, that is to say, at
what position of the header of a command they are inserted.
Example: :SOURce:FM:POLarity NORMal
This command contains the key word POLarity at the third
command level. It defines the polarity between the modulator
and the modulation signal.
Example :SOURce:FM:EXTernal:POLarity NORMal
This command contains the key word POLarity at the fourth
command level. It defines the polarity between the modulation
voltage and the resulting direction of the modulation only for the
external signal source indicated.
Optional key words:
Some command systems permit certain key words to be optionally inserted
into the header or omitted. These key words are marked in the description
by square brackets. The instrument must recognize the full command
length for reasons of compatibility with the SCPI standard. Some
commands can be considerably shortened by omitting optional key words.
Example: [SOURce]:POWer[:LEVel][:IMMediate]:OFFSet 1
This command immediately sets the offset of the signal to 1 dB.
The following command has the same effect:
POWer:OFFSet 1
Note:
Long and short form:
Key words have a long form and a short form. Either the long form or the
short form may be entered, other abbreviations are not permissible.
Example: STATus:QUEStionable:ENABle 1= STAT:QUES:ENAB 1
Note:
1090.3123.12
An optional key word must not be omitted if its effect is specified
in greater detail by means of a numerical suffix.
The short form is characterized by upper-case letters, the long
form corresponds to the complete word. Upper-case and lowercase notation only serve the above purpose, the device itself
does not make any difference between upper-case and lowercase letters.

Parameters:
A parameter must be separated from the header by a "white space". If a
command includes several parameters, they are separated by a comma
",". Some queries permit the parameters MINimum, MAXimum and
DEFault to be entered. For a description of these parameter types see
section "Parameters".
Example: SOURce:POWer:ATTenuation? MAXimum
Response: 60
This query requests the maximum value for the attenuation.
Numerical suffix:
If a device has several functions or features of the same kind, eg inputs,
the desired function can be selected by appending a suffix to the
command. Entries without suffix are interpreted like entries with the
suffix 1.
Example: SOURce2:FREQuency:MODE CW
This command determines the operating mode for the
Frequency Subsystem.

Structure of Command Lines
A command line may contain one or several commands. It is terminated by ,
with EOI or EOI together with the last data byte. QuickBASIC automatically produces EOI together with
the last data byte.
Several commands in a command line are separated by a semicolon ";". If the next command belongs
to a different command system, the semicolon is followed by a colon.
Example:
CALL IBWRT(generator%, "SOURce:POWer:CENTer MINimum;:OUTPut:ATTenuation 10")
This command line contains two commands. The first command belongs to the SOURce
system and defines the center frequency of the output signal. The second command
belongs to the OUTPut system and sets the attenuation of the output signal.
If successive commands belong to the same system and thus have one or several levels in common,
the command line can be abbreviated. To this end, the second command (after the semicolon) is
started with the level that lies below the common levels (see also Fig. 5-1). The colon following the
semicolon must be omitted in this case.
Example:
CALL IBWRT(generator%, "SOURce:FM:MODE LOCKed;:SOURce:FM:INTernal:FREQuency 1kHz")
This command line is represented in its full length and contains two commands separated
from each other by the semicolon. The two commands belong to the SOURce command
system, subsystem FM, ie they have two common levels.
To abbreviate the command line, the second command is started with the level below
SOURce:FM. The colon after the semicolon is omitted.
The abbreviated form of the command line reads as follows:
CALL IBWRT(generator%, "SOURce:FM:MODE LOCKed;INTernal:FREQuency 1kHz")
However, a new command line always has to be started with the complete path.
Example:
CALL IBWRT(generator%, "SOURce:FM:MODE LOCKed")
CALL IBWRT(generator%, "SOURce:FM:INTernal:FREQuency 1kHz")
Responses to Queries
For each setting command, a query is defined unless explicitly specified otherwise. The query is formed
by adding a question mark to the setting command in question. Responses to queries to the SCPI
standard are partly subject to stricter rules than responses to the IEEE 488.2 standard.
1.
The requested parameter is transmitted without header.
Example: SOURce:EXTernal:COUPling?
Response: AC
2.
Maximum values, minimum values and all further quantities requested via a special text parameter
are returned as numerical values.
Example: FREQuency? MAX
Response: 10E3
3.
Numerical values are output without a unit. Physical quantities are referred to the basic units or to
the units set with the Unit command.
Example: FREQuency?
Response: 1E6 for 1 MHz
4.
Truth values (Boolean parameters) are returned as 0 (for Off) and 1 (for On).
Example: OUTPut:STATe?
5.
Text (character data) is returned in a short form.

Parameters
The following examples are general, they are not necessarly available with R&S SML / R&S SMV03.
Most commands require a parameter to be specified. Parameters must be separated from the header
by a "white space". Permissible parameters are numerical values, Boolean parameters, text, character
strings and block data. The parameter type required for a given command and the permissible range of
values are specified in the command description.
Numerical values
Numerical values can be entered in any form, ie with sign, decimal point and
exponent. Values exceeding the resolution of the instrument are rounded up or
down. The mantissa may comprise up to 255 characters, the exponent must be
in the value range -32 000 to 32 000. The exponent is preceded by an "E" or
"e". Specifying the exponent alone is not permissible. In the case of physical
quantities, the unit can be entered. Permissible unit prefixes are G (giga), MA
(mega, MOHM and MHz being also permissible), K (kilo), M (milli), U (micro)
and N (nano). If no unit is entered, the basic unit is used.
Example: SOURce:FREQuency 1.5 kHz = SOURce:FREQuency 1.5E3
Special numerical
values
The texts MINimum, MAXimum, DEFault, UP and DOWN are interpreted as
special numerical values.
In the case of a query, the numerical value is returned.
Example: Setting command: SOURce:VOLTage MAXimum
Query:
SOURce:VOLTage?
Response: 15
MIN/MAX
MINimum and MAXimum denote the minimum and the maximum value.
DEF
DEFault denotes a preset value stored in an EPROM. This value conforms to
the default setting as called by the *RST command.
UP/DOWN
UP/DOWN increases or decreases the numerical value by one step. The step
width can be defined via an allocated step command for each parameter which
can be set via UP/DOWN (see List of Commands, chapter 6).
INF/NINF
INFinity, Negative INFinity (NINF) represent the numerical values –9.9E37 or
9.9E37, respectively. INF and NINF are only sent as device responses.
NAN
Not A Number (NAN) represents the value 9.91E37. NAN is only sent as a
device response. This value is not defined. Possible causes are the division of
zero by zero, the subtraction of infinite from infinite and the representation of
missing values.
Boolean Parameters
Text
1090.3123.12
Boolean parameters represent two states. The ON state (logically true) is
represented by ON or a numerical value unequal to 0. The OFF state (logically
untrue) is represented by OFF or the numerical value 0. In the case of a query,
0 or 1 is returned.
Example: Setting command: SOURce:FM:STATe ON
Query:
SOURce:FM:STATe?
Response: 1
Text parameters follow the syntactic rules for key words, ie they can be entered
using a short or a long form. Like any other parameter, they must be separated
from the header by a "white space". In the case of a query, the short form of the
text is returned.
Example: Setting command: :OUTPut:FILTer:TYPE

Strings
Structure and Syntax of Device Messages
Strings must always be entered in inverted commas (' or ").
Example: SYSTem:LANGuage "SCPI"
:SYSTem:LANGuage 'SCPI'
Block data
or
Block data are a transmission format which is suitable for the transmission of
large amounts of data. A command with a block data parameter has the
following structure:
Example: HEADer:HEADer #45168xxxxxxxx
The data block is preceded by the ASCII character #. The next number indicates
how many of the following digits describe the length of the data block. In the
example, the four following digits indicate the length to be 5168 bytes. This is
followed by the data bytes. During the transmission of the data bytes, all End or
other control signs are ignored until all bytes are transmitted. Data elements
comprising more than one byte are transmitted with the byte being the first
which was specified by the SCPI command "FORMat:BORDer".
The format of the binary data within a block depends on the IEC/IEEE-bus
command. The commands
:SOURce:CORRection:CSET:DATA:FREQuency
:SOURce:CORRection:CSET:DATA:POWer
:SYSTem:MSEQuence:DWELl
:SYSTem:MSEQuence:RCL
use the IEEE 754 format for double precision floating point numbers. Each
number is represented by 8 bytes.
Example:
a# = 125.345678E6
b# = 127.876543E6
CALL IBWRT(generator%, "SOURCE:CORRECTION:CSET:DATA:FREQ
#216" + MKD$(a#) + MKD$(b#))
– '#' in the command string introduces the binary block,
– '2' indicates that 2 digits specifying the length will follow next,
– '16' is the length of the binary block (in bytes), here: 2 double precision
floating point numbers of 8 bytes each.
– The binary data follow. Since the function IBWRT requires a text string,
MKD$ is used for type conversion.
The following ASCII format has the same effect:
CALL IBWRT(generator%, "SOURCE:CORRECTION:CSET:DATA:FREQ
125.345678E6, 127.876543E6")

Input Unit
The input unit receives commands character by character from the IEC/IEEE bus and stores them in the
input buffer. The input buffer has a size of 256 characters. The input unit sends a message to the
command recognition when the input buffer is full or when it receives a terminator, , as defined in IEEE 488.2, or the interface message DCL.
If the input buffer is full, the IEC/IEEE-bus traffic is stopped and the data received up to then are
processed. After this, the IEC/IEEE-bus traffic is continued. If, on receipt of a terminator, the input buffer
is not full, the input unit can receive the next command during command recognition and execution.
Receipt of a DCL command clears the input buffer and immediately initiates a message to the
command recognition.

Instrument Model and Command Processing
R&S®SML / R&S®SMV03
Command Recognition
The command recognition analyzes the data from the input unit in the order the data are received. Only
DCL commands are serviced with priority, whereas GET commands (Group Execute Trigger), for
example, are processed only after the previously received commands. Each recognized command is
immediately transferred to the data set but without being executed there at once.
Syntactic errors in commands are detected here and transferred to the status reporting system. The rest
of a command line following a syntax error is further analyzed and processed as far as possible.
If the command recognition recognizes a terminator or a DCL command, it requests the data set to set
the commands now also in the instrument hardware. After this, it is immediately ready to continue
processing commands. This means that new commands can be processed while the hardware is being
set ("overlapping execution").
Data Set and Instrument Hardware
The term "instrument hardware" is used here to designate the part of the instrument which actually
performs the instrument functions: signal generation, measurement, etc. The controller is not included.
The data set is a detailed reproduction of the instrument hardware in the software.
IEC/IEEE-bus setting commands cause an alteration of the data set. The data set management enters
the new values (eg frequency) into the data set but passes them on to the hardware only upon request
by the command recognition. As this is only effected at the end of a command line, the sequence of
setting commands in the command line is not relevant.
The data are only checked for compatibility among one another and with the instrument hardware
immediately before they are transferred to the instrument hardware. If it is found that an execution is not
possible, an "execution error" is signalled to the status reporting system. All alterations mad to the data
set are cancelled, and the instrument hardware is not reset. Due to the delayed checking and hardware
setting it is permissible however that impermissible instrument states are briefly set within a command
line without an error message being produced. At the end of the command line, however, a permissible
instrument state must be attained.
Before the data are passed on to the hardware, the settling bit in the STATus:OPERation register is set.
The hardware makes the settings and resets the bit when the new state has settled. This procedure can
be used for synchronization of command processing.
IEC/IEEE-bus queries cause the data set management to send the desired data to the output unit.
Status Reporting System
The status reporting system collects information on the instrument state and makes it available to the
output unit upon request. A detailed description of the structure and function is given in section "Status
Reporting System".

Output Unit
The output unit collects the information requested by the controller and output by the data set
management. The output unit processes the information in accordance with the SCPI rules and makes it
available in the output buffer. The output buffer has a size of 256 characters. If the requested
information exceeds this size, it is made available in portions without this being recognized by the
controller.
If the instrument is addressed as a talker without the output buffer containing data or awaiting data from
the data set management, the output unit returns the error message "Query UNTERMINATED" to the
status reporting system. No data are sent on the IEC/IEEE bus. The controller waits until it has reached
its time limit. This procedure is specified by SCPI.
Command Sequence and Command Synchronization
As mentioned above, overlapping execution is possible for all commands. Likewise, the setting
commands of a command line are not necessarily processed in the order in which they are received.
To ensure that commands are carried out in a specific order, each command must be sent in a separate
command line, ie with a separate IBWRT() call.
To prevent overlapping execution of commands, one of commands *OPC, *OPC? or *WAI has to be
used. Each of the three commands causes a certain action to be triggered only after the hardware has
been set and has settled. The controller can be programmed to wait for the respective action to occur
(see Table 5-1).

Status Reporting System
R&S®SML / R&S®SMV03
Status Reporting System
The status reporting system (see Fig. 5-4) stores all information on the current operating state of the
instrument, for example on any errors that have occurred. This information is stored in status registers
and in an error queue. The status registers and the error queue can be queried via the IEC/IEEE bus.
The information is of a hierarchical structure. The highest level is formed by the status byte (STB)
register defined in IEEE 488.2 and the associated service request enable (SRE) mask register. The STB
register receives information from the standard event status register (ESR) which is also defined in IEEE
488.2 with the associated standard event status enable (ESE) mask register, and from the registers
STATus:OPERation and STATus:QUEStionable which are defined by SCPI and contain detailed information on the instrument.
The status reporting system further comprises the IST flag ("Individual STatus") with the parallel poll
enable (PPE) register allocated to it. The IST flag, like the SRQ, combines the entire instrument state in
a single bit. The function fulfilled by the PPE register for the IST flag corresponds to that fulfilled by the
SRE for the service request.
The output buffer contains the messages the instrument returns to the controller. The output buffer is
not part of the status reporting system but determines the value of the MAV bit in the STB register and is
therefore shown in Fig. 5-4.
Structure of an SCPI Status Register
Each SCPI register consists of five parts each of 16 bits width which have different functions (see Fig.
5-3). The individual bits are independent of each other, ie each hardware status is assigned a bit
number which is valid for all five parts. For example, bit 3 of the STATus:OPERation register is assigned
to the hardware status "Wait for trigger" for all five parts. Bit 15 (the most significant bit) is set to zero for
all five parts. This allows the controller to process the contents of the register parts as positive integer.

Status Reporting System
CONDition part
The CONDition part is directly written to by the hardware or the sum bit of the
next lower register. Its contents reflects the current instrument status. This
register part can be read only but not written to or cleared. Reading does not
affect it contents.
PTRansition part
The Positive Transition part acts as an edge detector. If a bit of the CONDition
part changes from 0 to 1, the status of the associated PTR bit determines
whether the EVENt bit is set to 1.
PTR bit = 1: the EVENt bit is set.
PTR bit = 0: the EVENt bit is not set.
This part can be written to and read. Reading does not affect its contents.
NTRansition part
The Negative Transition part likewise acts as an edge detector. If a bit of the
CONDition part changes from 1 to 0, the status of the associated NTR bit
determines whether the EVENt bit is set to 1.
NTR bit = 1: the EVENt bit is set.
NTR bit = 0: the EVENt bit is not set.
This part can be written to and read. Reading does not affect its contents.
With the above two edge register parts, the user can define what status
transition of the CONDition part (none, 0 to 1, 1 to 0 or both) is to be stored in
the EVENt part.
EVENt part
The EVENt part indicates whether an event has occurred since it was read the
last time; it is the "memory" of the CONDition part. It indicates only those
events that were passed on by the edge filters. The EVENt part is continuously
updated by the instrument. This part can be read only. Upon reading, its
contents is set to zero. In linguistic usage, the EVENt part is often treated as
equivalent to the complete register.
ENABle part
The ENABle part determines whether the associated EVENt bit contributes to
the sum bit (see below). Each bit of the EVENt part is ANDed with the
associated ENABle bit (symbol '&'). The results of all logical operations of this
part are passed on to the sum bit via an OR function (symbol '+').
ENABle-Bit = 0:
the associated EVENt bit does not contribute to the sum bit.
ENABle-Bit = 1:
if the associated EVENT bit is "1", the sum bit is set to "1"
as well.
This part can be written to and read. Reading does not affect its contents.
Sum bit
As mentioned above, the sum bit is obtained from the EVENt part and the
ENABle part for each register. The result is entered as a bit of the CONDition
part into the next higher register.
The instrument automatically generates a sum bit for each register. It is thus
ensured that an event, for example a PLL that has not locked, can produce a
service request throughout all hierarchical levels.
Note:
The service request enable (SRE) register defined in IEEE 488.2 can be taken as the
ENABle part of the STB if the STB is structured in accordance with SCPI. Analogously, the
ESE can be taken as the ENABle part of the ESR.

Status Reporting System
Description of Status Registers
Status Byte (STB) and Service Request Enable Register (SRE)
The STB is already defined in IEEE 488.2. It provides a rough overview of the instrument status by
collecting the pieces of information of the lower registers. It can thus be compared with the CONDition
part of an SCPI register and assumes the highest level within the SCPI hierarchy. A special feature is
that bit 6 acts as the sum bit of the remaining bits of the status byte.
The status byte is read using the command *STB? or a serial poll.
The STB is assigned an SRE. The SRE functionally corresponds to the ENABle part of the SCPI
registers. Each bit of the STB is assigned a bit of the SRE. Bit 6 of the SRE is ignored. If a bit is set in
the SRE and the associated bit in the STB changes from 0 to 1, a service request (SRQ) is generated
on the IEC/IEEE bus which triggers an interrupt in the controller (if the controller is configured
correspondingly) and can be further processed there.
The SRE can be set using the command *SRE and read using the command *SRE?.
Table 5-2
Meaning of the bits used in the status byte
Bit No.
Meaning
2
Error Queue Not Empty
This bit is set if an entry is made in the error queue.
If the bit is enabled by the SRE, each entry in the error queue generates a service request. Thus an error can be
recognized and determined in greater detail by polling the error queue. The poll provides an informative error
message. This procedure is recommended since it considerably reduces the problems involved in IEC/IEEE-bus
control.
3
QUEStionable Status sum bit
This bit is set if an EVENt bit is set in the QUEStionable status register and the associated ENABle bit is set to 1.
If the bit is set, this indicates a questionable instrument status which can be determined in greater detail by
polling the QUEStionable status register.
4
MAV bit (Message AVailable)
This bit is set if a message is available in the output buffer which can be read.
The bit can be used for the automatic reading of data from the instrument to the controller (see chapter 7,
"Programming Examples").
5
ESB bit
Sum bit of event status register. It is set if one of the bits of the event status register is set and enabled in the
event status enable register.
If the bit is set, this indicates a serious error which can be determined in greater detail by polling the event status
register.
6
MSS bit (Master Status Summary bit)
This bit is set if the instrument triggers a service request. This is the case if one of the other bits of this register
is set together with its mask bit in the service request enable (SRE) register.
7
OPERation Status Register sum bit
This bit is set if an EVENt bit is set in the OPERation status register and the associated ENABle bit is set to 1.
If the bit is set, this indicates that the instrument is just carrying out an action. The type of action can be
determined by polling the OPERation status register.

R&S®SML / R&S®SMV03
IST Flag and Parallel Poll Enable Register (PPE)
Analogously with the SRQ, the IST flag combines the entire status information in a single bit. It can be
queried by means of a parallel poll (see section "Parallel Poll") or using the command *IST?.
The parallel poll enable (PPE) register determines which bits of the STB contribute to the IST flag. The
bits of the STB are ANDed with the corresponding bits of the PPE. Unlike the SRE, bit 6 is used in this
case. The IST flag results from the ORing of all results. The PPE can be set using the command *PRE
and read using the command *PRE?.
Event Status Register (ESR) and Event Status Enable Register (ESE)
The ESR is already defined in IEEE 488.2. It can be compared with the EVENt part of an SCPI register.
The event status register can be read using the command *ESR?.
The ESE is the associated ENABle part. It can be set using the command *ESE and read using the
command *ESE?.

Operation Complete
This bit is set on receipt of the command *OPC when all previous commands have been executed.
2
Query Error
This bit is set if either the controller wants to read data from the instrument without having sent a query, or if it
does not fetch requested data and sends new instructions to the instrument instead. The cause is often a query
which is errored and hence cannot be executed.
3
Device-Dependent Error
This bit is set if a device-dependent error occurs. An error message with a number between -300 and -399 or a
positive error number, which denotes the error in greater detail, is entered into the error queue (see Chapter 9,
Section "Error Messages").
4
Execution Error
This bit is set if a received command is syntactically correct but cannot be executed for other reasons. An error
message with a number between -200 and –300, which denotes the error in greater detail, is entered into the
error queue (see Chapter 9, Section "Error Messages").
5
Command Error
This bit is set if a command is received which is undefined or syntactically not correct. An error message with a
number between -100 and –200, which denotes the error in greater detail, is entered into the error queue (see
Chapter 9, Section "Error Messages").
6
User Request
This bit is set when the [LOCAL] key is pressed, ie when the instrument is switched over to manual control.
7
Power On (AC supply voltage On)
This bit is set on switching on the instrument.

Use of Status Reporting System
To make effective use of the status reporting system, the information collected there must be
transferred to the controller and further processed. There are several methods to this effect which are
described in the following. For detailed examples see chapter 7, "Programming Examples").
Service Request, Making Use of Hierarchy Structure
Under certain conditions, the instrument can send a service request (SRQ) to the controller. The service
request normally triggers an interrupt at the controller to which the control program can respond with
corresponding actions. Fig. 5-4 shows that an SRQ is triggered if one or several of the bits 2, 3, 4, 5 and
7 of the status byte are set and enabled in the SRE. Each of these bits combines the information of
another register, the error queue or the output buffer. By setting the ENABle parts of the status registers
accordingly, it is achieved that arbitrary bits of an arbitrary status register trigger an SRQ. To make use
of the possibilities of the service request, all bits of the SRE and ESE enable registers should be set to "1".
Examples (see also Fig. 5-4 and chapter 7, "Programming Examples"):
Use of command *OPC to generate an SRQ
Set bit 0 in the ESE (Operation Complete).
Set bit 5 in the SRE (ESB).
The instrument generates an SRQ after completion of its settings.
Indication of end of sweep by means of an SRQ at the controller
Set bit 7 (sum bit of STATus:OPERation register) in SRE.
Set bit 3 (sweeping) in STATus:OPERation:ENABle.
Set bit 3 in STATus:OPERation:NTRansition so that the transition of sweeping bit 3 from 1 to 0
(end of sweep) is recorded in the EVENt part.
The instrument generates an SRQ after completion of a sweep.
The SRQ is the only way for the instrument to become active on its own. Each controller program
should, therefore, set the instrument such that a service request is triggered in the event of a
malfunction. The program should react appropriately to the service request. A detailed example of a
service request routine is included in chapter 7, "Programming Examples".
Serial Poll
In a serial poll, just as with command *STB, the status byte of an instrument is queried. However, the
query is implemented by means of interface messages and is therefore clearly faster. The serial-poll
method has already been defined in IEEE 488.1 and used to be the only standard method for different
instruments to query the status byte. The method also works with instruments which do not adhere to
SCPI nor to IEEE 488.2.
The QuickBASIC command for executing a serial poll is IBRSP(). Serial polling is mainly used to obtain
a fast overview of the states of several instruments connected to the IEC/IEEE bus.
1090.3123.12
5.22
E-6
R&S®SML / R&S®SMV03
Status Reporting System
Parallel Poll
In a parallel poll, up to eight instruments are simultaneously requested by the controller by means of a
single command to transmit 1 bit of information each on the data lines, ie to set the data line allocated to
each instrument to logically "0" or "1". Analogously to the SRE register, which determines under what
conditions an SRQ is generated, there is a parallel poll enable (PPE) register, which is likewise ANDed
with the STB bit by bit, with bit 6 being taken into account. The results are ORed, and the result of this is
sent (possibly inverted) in response to a parallel poll by the controller. The result can also be queried
without a parallel poll using the command *IST.
The instrument first has to be set for parallel polling by means of the QuickBASIC command IBPPC().
This command allocates a data line to the instrument and determines whether the response is to be
inverted. The parallel poll itself is executed using IBRPP().
The parallel-poll method is mainly used in order to find out quickly, after an SRQ, which instrument has
sent the service request if there are many instruments connected to the IEC/IEEE bus. To this effect,
the SRE and the PPE must be set to the same value. A detailed example on parallel polling will be found
in chapter 7, "Programming Examples".
Query by Means of Commands
Each part of every status register can be read by means of a query. The queries to be used are included
with the detailed description of the registers. In response to a query, a number is always returned which
represents the bit pattern of the register queried. The number is evaluated by the controller program.
Queries are normally used after an SRQ to obtain more detailed information on the cause of the SRQ.
Error Queue Query
Each error state in the instrument leads to an entry in the error queue. The entries to the error queue are
detailed plain-text error messages which can be displayed in the Error menu by manual control or
queried via the IEC/IEEE bus with the command SYSTem:ERRor?. Each call of SYSTem:ERRor?
provides one entry from the error queue. If no more error messages are stored there, the instrument
responds with 0, ie "No error".
The error queue should be queried by the controller program after each SRQ as the entries provide a
more precise description of the cause of an error than the status registers. Especially during the test
phase of a controller program the error queue should be queried regularly since errored commands
from the controller to the instrument are also recorded in the error queue.

Transmission Parameters
To ensure error-free and correct data transmission, the transmission parameters on the instrument and
the controller must have the same settings. The settings are made in the Utilities - System-RS232
menu.
Transmission rate
(baud rate)
Eight different baud rates can be set on the instrument:
1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200
Data bits
Data transmission is in 8-bit ASCII code. The LSB (least significant
bit) is transmitted as the first bit.
Start bit
The transmission of a data byte is initiated with a start bit. The
falling edge of the start bit indicates the beginning of the data byte.
Parity bit
No parity bit is used.
Stop bit
The transmission of a data byte is terminated by a stop bit.
Example:

Interfaces
R&S®SML / R&S®SMV03
Handshake
Software handshake
The software handshake with the XON/XOFF protocol controls data transmission.
If the receiver (instrument) wishes to inhibit the input of data, it sends XOFF to the transmitter. The
transmitter then interrupts data output until it receives XON from the receiver. The same function is also
provided at the transmitter end (controller).
Note:
The software handshake is not suitable for the transmission of binary data. Here the
hardware handshake is to be preferred.
Hardware handshake
With a hardware handshake, the instrument signals its readiness for reception via the lines DTR and
RTS. A logic 0 means "ready", a logic 1 means "not ready".
Whether or not the controller is ready for reception is signalled to the instrument via the CTS or the DSR
line (see section "Signal Lines"). The transmitter of the instrument is switched on by a logic 0 and off by
a logic 1. The RTS line remains active as long as the serial interface is active. The DTR line controls the
instrument’s readiness for reception.
Wiring between instrument and controller
Wiring between the instrument and the controller is by means of a null modem, ie the data, control and
signalling lines have to be cross-connected. The wiring plan below applies to controllers with a 9-pin or
25-pin connector.

Description of Commands
Remote Control – Description of Commands
In the following sections, all commands implemented in the instrument are first listed in tables and then
described in detail, separated according to the command system. The notation corresponds to the one
of the SCPI standards to a large extent. The SCPI conformity information can be taken from the list of
commands at the end of this chapter.
The description of manual operation, Chapter 4, indicates the corresponding IEC/IEEE-bus command
for each manual setting.
A general introduction to remote control and a description of the status registers are to be found in
Chapter 5. Detailed program examples of the main functions are to be found in Chapter 7.
Note: In contrast to manual control, which is intended for maximum possible operating convenience,
the priority of remote control is the predictability of the device status. This means that when
incompatible settings are attempted, the command is ignored and the device status remains
unchanged, i.e. is not adapted to other settings. Therefore, IEC/IEEE-bus control programs
should always define an initial device status (e.g. with command *RST) and then implement the
required settings.
This manual contains the commands (syntax) of the firmware version 2.51.
Notation
Table of Commands
Command:
In the command column, the table provides an overview of the commands
and their hierarchical arrangement (see indentations).
Parameter:
In the parameter column the requested parameters are indicated together
with their specified range.
Unit:
The unit column indicates the basic unit of the physical parameters.
Remark:
In the remark column an indication is made on
– whether the command does not have a query form,
– whether the command has only one query form,
– whether this command is implemented only with a certain option of the
instrument.
Indentations
The different levels of the SCPI command hierarchy are represented in the
table by means of indentations to the right. The lower the level is, the
farther the indentation to the right is. Please observe that the complete
notation of the command always includes the higher levels as well.
Example:
:SOURce:FM:MODE is represented in the table as follows:
:SOURce
:FM
:MODE
first level
second level
third level
In the individual description, the complete notation of the command is given. An example for each
command and - if it exists - the default value (*RST) is written out at the end of the individual description.

Description of Commands
Upper/lower case
notation
Special characters
R&S®SML / R&S®SMV03
Upper/lower case letters serve to mark the long or short form of the key
words of a command in the description. The instrument itself does not
distinguish between upper and lower case letters.
|
A selection of key words with an identical effect exists for several
commands. These key words are indicated in the same line, they are
separated by a vertical stroke. Only one of these key words has to be
indicated in the header of the command. The effect of the command is
independent of which of the key words is indicated.
Example: :SOURce
:FREQuency
:CW|:FIXed
The two following commands of identical meaning can be formed. They set
the frequency of the constantly frequent signal to 9 kHz:
:SOURce:FREQuency:CW 9E3 = SOURce:FREQuency:FIXed 9E3
A vertical stroke in indicating the parameters marks alternative possibilities
in the sense of "or". The effect of the command is different, depending on
which parameter is entered.
Example: Selection of the parameters for the command
SOURce:COUPling AC | DC
If parameter AC is selected, only the AC content is fed through, in
the case of DC, the DC as well as the AC content.
1090.3123.12
[ ]
Key words in square brackets can be omitted when composing the header
(cf. Chapter 5, Section "Optional Keywords"). The full command length
must be accepted by the instrument for reasons of compatibility with the
SCPI standards.
Parameters in square brackets can optionally be incorporated in the
command or omitted as well.
{ }
Parameters in braces can optionally be incorporated in the command either
not at all, once or several times.

*IDN?
IDENTIFICATION QUERY queries the instrument identification.
The device response is for example: "Rohde&Schwarz,R&S SML01,00000001,1.04"
01 = variant identification
00000001= serial number
1.04 = firmware version number
*IST?
INDIVIDUAL STATUS QUERY returns the contents of the IST flag in decimal form (0 | 1). The
IST flag is the status bit which is sent during a parallel poll.
*OPC
OPERATION COMPLETE sets bit 0 in the event status register when all preceding commands
have been executed. This bit can be used to initiate a service request.
*OPC?
OPERATION COMPLETE QUERY returns 1, if all preceding commands have been executed. It
is necessary to consider a sufficiently long time-out for the IEEE/IEC-bus.
*OPT?
OPTION IDENTIFICATION QUERY queries the options included in the instrument and returns a
list of the options installed. The options are separated from each other by means of commas. For
every option, a fixed position is provided in the response.

Common Commands
*RCL 1 to 50
RECALL calls the instrument state which was stored under the number supplied using command
*SAV. 50 instrument states can be stored.
*RST
RESET sets the instrument to a defined default status. The command essentially corresponds to
pressing the [PRESET] key. The state of the RF-output is an exception: The RF-output is
deactivated after *RST, however, it is activated after the [PRESET] key has been pressed. The
default setting is indicated in the description of the commands.
*SAV 1 to 50
SAVE stores the current instrument state under the number indicated (cf. *RCL as well).
*SRE 0 to 255
SERVICE REQUEST ENABLE sets the service request enable register to the value indicated. Bit
6 (MSS mask bit) remains 0. This command determines under which conditions a service request
is triggered. Query *SRE? reads the contents of the service request enable register in decimal
form. Bit 6 is always 0.
*STB?
READ STATUS BYTE QUERY reads out the contents of the status byte in decimal form.
*TRG
TRIGGER triggers all actions waiting for a trigger event. Special trigger events can be started by
command system "TRIGger" (see section "TRIGger System").
*WAI

[:SOURce]:POWer[:LEVel][:IMMediate][:AMPLitude] -140 dBm to Pmax
(+29 dBm with R&S SML-B10)
The command sets the RF output level in operating mode CW. UP and DOWN can be indicated
in addition to numeric values. Then the level is increased or reduced by the value indicated under
[:SOUR]:POW:STEP.
In this command, the OFFSet value is considered. Thus the specified range indicated is only valid
for :SOUR:POW:OFFS 0.
The keywords of this command are optional to a large extent, thus the long as well as the short
form of the command is shown in the example.
Example:
:SOUR:POW:LEV:IMM:AMPL -10
:POW –10
or
*RST value is -30 dBm
[:SOURce]:POWer[:LEVel][:IMMediate][:AMPLitude]:OFFSet -100 to +100 dB
The command enters the constant level offset of a series-connected attenuator/ amplifier (cf.
Chapter 4, Section "Level Offset"). If a level offset is entered, the level entered using :POW does
no longer conform to the RF output level. The following relation is true:
:POW = RF output level + :POW:OFFS
Entering a level offset does not change the RF output level but only the value queried by :POW.
The level offset is also valid for level sweep!
Only dB is permissible as a unit here, linear units (V, W etc.) are not permitted.
Example:
:SOUR:POW:LEV:IMM:AMPL:OFFS 0
:POW:OFFS 0
or
*RST value is 0 dB
[:SOURce]:POWer:LIMit[:AMPLitude] -140 dBm to Pmax (+29 dBm with R&S SML-B10)

Only level values between STARt and STOP are permitted (as to specified range, cf. :POW:AMPL).
Example:
*RST value is -30 dBm
:SOUR:POW:MAN 1dBm
[:SOURce]:POWer:MODE CW | FIXed | SWEep
The command specifies the operating mode and thus also by means of which commands the
level setting is checked.

sweep runs from the high to the low level (As to specified range, cf. :POW).
Example:
*RST value is -30 dBm
:SOUR:POW:STAR -20
[:SOURce]:POWer:STOP -140 dBm to Pmax (+29 dBm with R&S SML-B10)

[:SOURce]:PULSe:DELay 20 ns to 1.3 s
The command specifies the time from the start of the period to the first edge of the pulse. Due to
the construction of the instrument, this parameter is set to 0 if [:SOUR]:PULS:DOUB:STAT is
set to ON. The old value is activated again as soon as the double pulse has been switched off.
Example:
*RST value is 1 Ts
:SOUR:PULS:DEL 10us
[:SOURce]:PULSe:DOUBle
The commands to check the second pulse are under this node. If [:SOUR]:PULS:DOUB:STAT
is set to ON, a second pulse whose width is identical to the first pulse is generated in every period.
[:SOURce]:PULSe:DOUBle:DELay 60 ns to 1.3 s
The command sets the delay time from the start of the pulse period to the first edge of the second
pulse.
Example:
:SOUR:PULS:DOUB:DEL 10us
*RST value is 1 Ts
[:SOURce]:PULSe:DOUBle:STATe ON | OFF
The command switches the second pulse on or off.
ON
The second pulse is switched on.
Parameter [:SOUR]:PULS:DEL is set to 0 and cannot be changed. WIDTh >
(PULS:PER - PULS:DOUB:DEL)/2 results in error message -221, "Settings conflict".
OFF
The second pulse is switched off.
Example:
:SOUR:PULS:DOUB:STAT OFF
*RST value is OFF
[:SOURce]:PULSe:PERiod 100 ns to 85 s
The command sets the pulse period.
The pulse period is the reciprocal value of the pulse frequency, thus this command is coupled to
command [:SOUR]:PULM:INT:FREQ.

:SOURce2:SWEep[:FREQuency]:STEP[:LINear] 0 to 1 MHz
The command sets the step width with the linear sweep. If STEP:LIN is changed, the value of
POINts valid for SPAC:LIN also changes according to the formula defined under POINts. A
change of SPAN does not cause a change of STEP:LIN. Keyword [:LIN] can be omitted, then
the command conforms to SCPI regulation (see example).
Example:
*RST value is 1 kHz
:SOUR2:SWE:STEP 10kHz
:SOURce2:SWEep[:FREQuency]:STEP:LOGarithmic 0.01 to 100PCT
This command defines the step width factor for logarithmic sweeps. The next frequency value of
a sweep is calculated as follows (if STARt < STOP) :
New frequency = previous frequency + STEP:LOG x previous frequency
STEP:LOG , therefore, indicates the fraction of the previous frequency by which that frequency is
increased for the next sweep step. STEP:LOG is usually indicated in percent, with the suffix PCT
having to be used explicitly. If STEP:LOG is changed, the value of POINts valid for
SPACing:LOGarithmic also changes according to the formula stated under POINts. A change
of STARt or STOP does not result in a change of STEP:LOGarithmic.

The command to set the serial interface are under this node. The data format is fixedly set to 8
data bits, no parity and 1 stop bit. These values cannot be changed. The device represents a DTE
(Data Terminal Equipment) in relation to the serial interface. Therefore the the controller must be
connected via a 0-modem.

The commands sets the baud rate for both the transmit and the receive direction. *RST has no
influence on this parameter.
Example:
*RST value is 9600
:SYST:COMM:SER:BAUD 1200
:SYSTem:COMMunicate:SERial:BITS 7 | 8
The command sets the length of a data word.
Example:
*RSTvalue is 7
:SYST:COMM:SER:BITS
:SYSTem:COMMunicate:SERial:SBITs 1 | 2
The command defines whether 1 or 2 stop bits are used.
Example:
*RST value is 1
:SYST:COMM:SER:SBIT
:SYSTem:COMMunicate:SERial:CONTrol:RTS ON | IBFull | RFR
The commands sets the hardware handshake. *RST has no influence on this parameter.
ON
Interface line RTS is always active.
IBFull | RFR Input Buffer Full | Ready For Receiving.
Interface line RTS remains active as long as the instrument is ready to receive data.
Example:
*RST value is RFR
:SYST:COMM:SER:CONT:RTS ON
:SYSTem:COMMunicate:SERial:PACE XON | NONE
The command sets the software handshake. *RST has no influnence on this parameter.
XON
Software handshake using the ASCII codes 11h (XON) and 13h (XOFF).
Note: This mode is not recommended for binary data and for baud rates above
9600 bauds.
NONE
No software handshake.
Example:
*RST value is NONE
:SYST:COMM:SER:PACE NONE
:SYSTem:COMMunicate:SERial:PARity ODD | EVEN | NONE
The command defines the parity test.
Example:
:SYST:COMM:SER:PAR
*RST value is EVEN
ODD
:SYSTem:DISPlay:UPDate[:STATe] ON | OFF
ON The header line of the display indicates frequency and level values.
OFF The header line of the display remains empty.
This function is only available via IEC/IEEE-bus.
Example:
*RST value is ON
:SYST:DISP:UPD OFF
:SYSTem:ERRor?
The command queries the entry that has been in the error queue for the longest time. Positive
error numbers denote errors specific of the instrument, negative error numbers denote error
messages specified by SCPI (see Chapter 9). If the error queue is empty, 0, "No error", is
returned. The command is identical to STAT:QUE:NEXT?
Example:
1090.3123.12
Answer: -221, "Settings conflict"
:SYST:ERR?

R&S®SML / R&S®SMV03
:SYSTem:PRESet
The command triggers an instrument reset. It has the same effect as the PRESET key of the manual
control or as command *RST. This command triggers an event and hence has no *RST value.
Note:
By means of the "Preset RF State" item in the Level/Level menu, it is possible to
determine the switching state of the RF connector. The selected state is activated
when the :SYST:PRES command is sent.
If "Preset RF State“ = OFF, the command has the same effect as *RST
Example:
:SYST:PRES
:SYSTem:PROTect[1|2|3|4]
The command to disable certain instrument functions is under this node. A list of the functions
concerned can be found in the manual control (Chapter 4, Section "Password Input With
Protected Functions"). There are four protection levels which are distinguished by means of a
suffix after PROT. *RST has no effects on the disabling/enabling of the instrument functions.
:SYSTem:PROTect[1|2|3|4][:STATe] ON | OFF, Password
The command switches a protection level on or off. The passwords are 6-digit numbers. They
are fixedly stored in the firmware. The password for the first level is 123456.
ON
disables the functions belonging to this protection level. A password doesn't have to
be entered.
OFF
deactivates the disabling again if the correct password is entered. Otherwise an error
-224, "Illegal parameter value" is generated and STATe remains ON.
Example:
:SYST:PROT1:STAT
OFF, 123456
:SYSTem:SECurity[:STATe] ON | OFF
The command switches the security state on or off.
ON
The following commands cannot be executed:
:DISP:ANN:ALL ON
:DISP:ANN:FREQ ON
:DISP:ANN:AMPL ON
OFF
In the transition from ON to OFF all data existing in the instrument except for the
calibrating data are deleted, especially all status registers, all instrument states and
all lists.
The command is not influenced by *RST and *RCL.
Example:
:SYST:SEC:STAT ON
:SYSTem:SERRor?
This command returns a list of all errors existing at the point of time of the query. The error
messages are separated by commas. This list corresponds to the indication on the ERROR page
with manual control (cf. Chapter 9, Section "Error Messages").
Example:
Answer:
:SYST:SERR?
-221, "Settings conflict", 153, "Input voltage out of range"
:SYSTem:VERSion?
The command returns the SCPI version number the instrument acts in accordance with. This
command is a query and thus has no *RST value.
Example:
1090.3123.12
Answer: 1994.0
:SYST:VERS?

TEST
TEST System
This system contains the commands to execute the selftest routines (RAM?, ROM? and BATT?) as well
as to directly manipulate the hardware modules (:TEST:DIR). The selftests return a "0" if the test has
been executed successfully, otherwise a value unequal to "0". All commands of this system do not have
an *RST value.
Caution:
The commands under node :TEST:DIR directly act on the respective hardware module
circumventing any security mechanisms. They are provided for service purposes and
should not be used by the user. Improper use of the commands may damage the module.

TRIGger
R&S®SML / R&S®SMV03
TRIGger System
The TRIGger system contains the commands to select the trigger source and to configure the external
trigger socket. The trigger sources for the individual signal sources (RF, LFGen) are distinguished by a
numerical suffix appended to TRIG. The suffix conforms to the numbering of the SOURce system:
TRIGger1 = RF generator
TRIGger2 = LFGen
The trigger system of the R&S SML / R&S SMV03 consists of a simplified implementation of the SCPI
trigger system. Compared to SCPI, the TRIGger system shows the following differences:
• No INIT command, the instrument behaves as if :INIT:CONT ON was set.
• There are several subsystems denoting the different parts of the instrument under TRIGger (SWEep,
PULSe).
Further commands as to the trigger system of the R&S SML / R&S SMV03 can be found in the ABORt
system.

:TRIGger1|2[:SWEep]
All commands to trigger a sweep are under this node. The settings here act on level and
frequency sweeps for RF generator (TRIG1) or LF generator (TRIG2).
:TRIGger1|2[:SWEep][:IMMediate]
The command immediately starts a sweep. Which sweep is executed depends on the respective
Mode setting, e.g. :SOUR:FREQ:MODE SWE. The command corresponds to manual-control
command Execute Single Sweep. This command triggers an event and thus has no *RST value.

:TRIGger1|2[:SWEep]:SOURce AUTO | SINGle | EXTernal
The command specifies the trigger source. The naming of the parameters directly corresponds to
the different settings with manual control. SCPI uses other designations for the parameters the
instrument accepts as well. These designations are to be preferred if compatibility is important.
The following table provides an overview.

Mode Single or Step
EXTernal
EXTernal
Mode Ext Trig Single or Ext Trig Step
AUTO
The trigger is free-running, i.e., the trigger requirement is permanently met. As soon
as a sweep has been terminated, the next one is started.
SINGle
Triggering is effected by means of IEC-bus commands :TRIG:SWE:IMM or *TRG. If
:SOUR:SWE:MODE is set to STEP, a step, in the case of the AUTO setting a complete
sweep, is executed.
EXTernal
Triggering is effected from outside via the TRIGGER socket or by the GET
command via IEC/IEEE-bus. The action triggered depends on the setting of the
sweep mode as in the case of SINGle.
Example:
:TRIG:SWE:SOUR AUTO
*RST value is SING
:TRIGger:PULSe
This node contains all commands to trigger the pulse generator (Option R&S SML-B3). The
commands are only valid for TRIGger1.
:TRIGger:PULSe:EGATed:POLarity NORMal | INVerted
The command defines the active level of the gate signal.
NORMal
INVerted
Active level = HIGH
Active level = LOW
Example:
:TRIG:PULS:EGAT:POL INV
*RST value is NORM
:TRIGger:PULSe:SOURce AUTO | SINGle | EXTernal | EGATed
The command specifies the trigger source.
AUTO
Trigger is free-running (see above).
SINGle
Triggering is effected by means of IEC-bus commands :TRIG:PULS:IMM.
EXTernal
EGATed
Example:
Triggering is effected from outside via the PULSE socket.
Triggering is effected when the gate signal is active.
*RST value is AUTO
:TRIG:PULS:SOUR AUTO
:TRIGger:PULSe:SLOPe POSitive | NEGative
The command defines whether the action triggered is triggered at the positive or the negative
edge of the trigger signal.
Example:
*RST value is POS:TRIGger:PULSe[:IMMediate]
:TRIG:PULS:SLOP NEG
:TRIGger:PULSe[:IMMediate]
The command immediately starts a pulse. The command corresponds to manual-control
command Execute Single Pulse. This command triggers an event and thus has no *RST value.

Maintenance
Maintenance
The present chapter describes the measures that are necessary for maintaining, storing and packing
the instrument.
The instrument does not need a periodic maintenance. What is necessary is essentially the cleaning of
the outside of the instrument.
However, it is recommended to check the rated data from time to time.
Storing and Packing
°
°
The instrument can be stored at a temperature of –40 C to +70 C. When stored for an extended period
of time, the instrument should be protected against dust.
The original packing should be used, particularly the protective covers at the front and rear, when the
instrument is to be transported or dispatched. If the original packing is no longer available, use a sturdy
cardboard box of suitable size and carefully wrap the instrument to protect it against mechanical
damage.
Exchanging the Lithium Battery
A lithium battery with a service life of approx. 5 years serves to supply the RAM with power. When the
battery is discharged, the data stored will be lost. Exchanging the battery is described in the Service
Manual.

List of Error Messages
Error Messages
The present chapter contains the error messages (short-term and long-term messages) of the R&S
SML / R&S SMV03.
Short-term message
The short-term message is displayed in the status line. Part of it
overwrites the status indications and disappears after approx. 2 seconds
or in the case of a new entry.
The instrument shows, e.g., short-term messages if the attempt is made
to enter an overrange or if incompatible operating modes deactivate one
another.
Long-term message
The long-term message is displayed in the status line by means of the
message "Err". Pressing the [ERROR] key calls the ERROR page in
which the messages are entered. Several messages can be entered at
the same time. The long-term message remains existing until there is no
cause any more. The ERROR page is exited using the [BACK] key.
The ERROR page offers access to long-term messages if the [ERROR] key is pressed.
Fig. 9-1
ERROR page
Notes:
- An error message "Err" does not necessarily point to a defect instrument. There are
various operating states which can cause an ERROR message, e.g. if the instrument is
set to external reference but no external reference is connected.
- Error -313 indicates the loss of calibration data and is also applicable in case of a cold
start (key [PRESET] is pressed during switch-on). The calibration values can be
restored with internal calibration routines. These routines are accessible via menu
Utilities - Calib (see section on calibration).

General
Performance Test
General
• The rated specifications of the signal generator are checked after a warm-up time of at least 15
minutes. Recalibration of the instrument is not necessary, with the exception of the FM offset
calibration.
• A defined default state is set prior to each measurement by pressing the PRESET key.
• The values in the following sections are not guaranteed. Only the specifications in the data sheet are
binding.
• The values in the data sheet are guaranteed limits. Due to measurement errors, these limits must be
extended by the tolerances of the measuring instruments used in the performance test.
• The maximum frequency fmax that can be set for each of the different R&S SML models is shown in
Table 10-1. This should be borne in mind when choosing test equipment.

Test setup 2, spectrum analyzer mode
The spectrum analyzer is operated as an FM demodulator. A process
controller transmits the start frequency and target frequency via the
IEC/IEEE bus. The spectrum analyzer is triggered by the positive edge
on the EOI line of the IEC/IEEE bus. If the process controller then
switches from the start frequency to the target frequency, the build-up
process appears on the spectrum analyzer screen.
Synchronize reference frequencies on R&S SML / R&S SMV03 and

Measurement principle
The two test transmitters are set to the measurement frequency and
synchronized with 90° phase offset (phase quadrature). The RF carrier is
suppressed by mixing at 0 Hz, and the mixer makes use of the phase
quadrature in order to deliver a voltage corresponding to the phase difference between the input signals. This voltage is measured by the
spectrum analyzer and can be converted into SSB phase noise.

the mixer being used.
For calibration purposes lower the level of the DUT by 40 dB and
detune one test transmitter by 20 kHz. Check the signal for
harmonics; the second and third harmonics must be more than 30 dB
below the fundamental. Use the analyzer to measure the reference
value at 20 kHz and make a note of this value.
Cancel the detuning and set the phase quadrature. Restore the level
of the DUT and detune the phase offset at the auxiliary transmitter.
Observe the output voltage from the mixer on the oscilloscope, until
the voltage reaches 0.
Read off the noise voltage from the analyzer, normalized to 1 Hz
bandwidth (noise level).
Analysis
Note the difference compared to the reference level and increase the
offset found by a further 6 dB for the second sideband measured at the
same time (correlated) and 40 dB for the level switchover. If the signal-tonoise ratio of the second test transmitter is not at least 10 dB better than
that of the DUT, the noise component of the reference transmitter must
also be determined and due allowance must be made.
The corrected signal-to-noise ratio is the required measured value.
Example: Let the reference level be measured as 12 dBm. At 20 kHz a
noise level of -78 dBm (1 Hz) is determined. The difference is
90 dB. Adding in the correction for the second sideband (6
dB) and the level switchover (40 dB) gives a signal-to-noise
ratio of -136 dB or a noise level of -136 dBc (dB referenced to
the carrier power).

Caution: This correction value applies to the set measurement
frequency only.
Measurement
Measure the level at the test frequencies.
The frequency response is the difference between the highest and
the lowest measured value.
The level error is the deviation from the set value.
Measurement method for very small levels (<-80 dBm)
Caution:
A prerequisite for correct measurement is full RF shielding of the components used.
Test setup
Test setup 1; a low-noise preamplifier must be connected between the
R&S SML / R&S SMV03 and the test receiver.
Measurement
Having measured a level, continue by carrying out a calibration.
This enables levels down to the lowest limits set for the R&S SML /
R&S SMV03 to be measured.
Output reflection coefficient
Test setup
Test setup 4, spectrum analyzer mode.
Test method
Since the VSWR of a source must be measured, a purely passive
measurement using the VSWR bridge is possible only at levels where
the output impedance of the electronic attenuator defines the VSWR.
At higher levels the influence of the level control must be included. This is
done with the aid of an auxiliary transmitter which transmits a wave into the
DUT. This wave has a slightly offset carrier frequency (the difference
frequency within the control bandwidth of the level control) and is
superimposed on the decaying wave of the DUT. At an ideal internal
impedance only the decaying wave of the DUT flows back into the bridge,
whilst at an internal impedance that deviates from the ideal there is
superposition of the two components. The frequency offset gives rise to a
beat. From the amplitude ratio of this beat, conclusions can be drawn with
regard to the VSWR.

as the reference level and make a note of it.
Unscrew the bridge from the R&S SML / R&S SMV03 and increase
the level on the second test transmitter until the reference level is
again being measured on the analyzer.
Screw the bridge or directional coupler back onto the R&S SML / R&S
SMV03.
The spectrum analyzer now shows a more or less wavy line
which represents the VSWR of the R&S SML / R&S SMV03. To
calculate the VSWR use the formula
VSWR = umax / umin
containing the maximum and minimum voltages.

Test setup 2, spectrum analyzer mode.
Measurement principle
The test receiver is operated in spectrum analyzer mode as a fast levelmeasuring instrument with a 0 Hz span. A process controller transmits
the start level and target level via the IEC/IEEE bus. The spectrum
analyzer is triggered by the positive edge on the EOI line of the
IEC/IEEE bus. If the process controller then switches from the start level
to the target level, the build-up process appears on the spectrum
analyzer screen.
Preparing the measurement
Synchronize reference frequencies on R&S SML / R&S SMV03 and
test receiver.
Establish IEC/IEEE bus and RF connections.
Connect trigger port to EOI line (pin 5) of IEC/IEEE bus.

Preliminary remark
R&S®SML / R&S®SMV03
Performance test - extension for R&S SMV03
Preliminary remark
• The rated characteristics of the signal generator are checked after a warm-up time of at least
30 minutes. A recalibration of the unit is not required. FM offset calibration is an exception,
however.
• A defined default state is set prior to each measurement by pressing the PRESET key.
• The values stated hereafter are not guaranteed values. Only the data sheet specifications
shall be binding.
• The values specified in the data sheet are guaranteed limits. The tolerances of the
instruments used in the performance test must be added to the limits because of their
measurement uncertainty.

the level again.
The voltage ratio of test level to reference level is the input
reflection coefficient r of the I input.
From this, the voltage standing wave ratio (VSWR) can be
calculated as follows:
VSWR = (1+r)/(1-r)
Repeat the measurement for the Q input.

Test method
By applying a sinewave AC voltage to the I (or Q) input, an amplitude
modulation with a suppressed carrier is generated. The modualtion
frequency response is determined by measuring the sidebands as a
function of the frequency of the applied AC voltage.
