Safety Instructions

2. Applicable local or national safety

regulations and rules for the
prevention of accidents must be
observed in all work performed. The
product may be opened only by
authorized, specially trained
personnel. Prior to performing any
work on the product or opening the

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.

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.

Safety Instructions

9. In the case of products of safety class
I with movable power cord and
connector, operation is permitted only
on sockets with earthing contact and
protective earth connection.

10. Intentionally breaking the protective
earth connection either in the feed
line or in the product itself is not
permitted. Doing so can result in the
danger of an electric shock from the
product. If extension cords or
connector strips are implemented,
they must be checked on a regular
basis to ensure that they are safe to
use.

11. If the product has no power switch for
disconnection from the AC supply,
the plug of the connecting cable is
regarded as the disconnecting

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.

12. 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.

13. 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).

14. Do not insert the plug into sockets
that are dusty or dirty. Insert the plug
firmly and all the way into the socket.

limiting, electrical separation,
insulation) should be taken to avoid
any hazards.

17. Ensure that the connections with
information technology equipment
comply with IEC 950/EN 60950.

18. 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.

19. If a product is to be permanently
installed, the connection between the
PE terminal on site and the product's
PE conductor must be made first
before any other connection is made.

water, unless otherwise specified
(see also safety instruction 1.). If this
is not taken into account, there exists
the danger of electric shock for the
user or damage to the product, which
can also lead to personal injury.

24. Never use the product under
conditions in which condensation has
formed or can form in or on the
product, e.g. if the product was
moved from a cold to a warm
environment.

25. Do not close any slots or openings on
the product, since they are necessary
for ventilation and prevent the product
from overheating. Do not place the
product on soft surfaces such as
sofas or rugs or inside a closed
housing, unless this is well ventilated.

26. Do not place the product on heat­generating devices such as radiators
or fan heaters. The temperature of
the environment must not exceed the
maximum temperature specified in
the data sheet.

27. Batteries and storage batteries must
not be exposed to high temperatures

Introduction

User interface

Menus for
configuring and
setting output
parameters

The task of the signal generator is to produce unmodulated and modulated
signals in a frequency range from 9 kHz to 3 GHz. In addition, LF signals in
the range from 20 Hz to 80 kHz can be output at the LF output on the front.

After switching on the R&S SM300, the user interface of the signal generator
is active. In the default state, the following is displayed.

The menus used to set the generator functions are displayed in the menu
area. Each menu contains specific functions for configuring the output signal.
Frequently used settings such as frequency (FREQ), level (LEVEL), RF
ON/OFF and MOD ON/OFF can be made in the MAIN menu. Further
parameters can be set in the following menus.

6.2.2.5 I/Q Modulation

Use

NOTE

Switching I/Q
modulation on

Switching I/Q
modulation off

With the IQ MOD function, virtually any desired output signal can be
generated, such as those needed in digital mobile radio. The I and Q signals
necessary for this must be provided by an arbitrary generator (e.

g. R&S

AMIQ). The I/Q outputs of the arbitrary generator are connected with the I/Q
inputs of the R&S SM300 [15, 16] via two identical cables with BNC
connectors. You obtain the modulated signal at the RF output of the
R&S SM300 after the I/Q MOD function has been switched on and I/Q signals
are applied to the inputs.

The rms value and the peak value of the signal change vis-à-vis the
unmodulated signal as a result of the modulation with external I/Q signals.
The level set in the R&S SM300 applies to the unmodulated signal and is no
longer directly related to the level of the modulated signal. Depending on the
modulation, signal peaks can occur which lie high above the set level value
(e.

g. in the case of CDMA signals).

1. Press the

function key in the

submenu.

The function key is highlighted. The new setting is saved.

After I/Q modulation is switched on, the newly modulated RF signal is
present at the RF output. "IQ" is displayed in the status line.
