.

Basic safety instructions

1. The product may be operated only under
the operating conditions and in the
positions specified by the manufacturer. Its
ventilation must not be obstructed during
operation. Unless otherwise specified, the
following requirements apply to
Rohde & Schwarz products:
prescribed operating position is always with
the housing floor facing down, IP protection
2X, pollution severity 2, overvoltage
category 2, use only in enclosed spaces,
max. operation altitude 2000 m above sea
level, max. transport altitude 4500 m above
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

the product or opening the product, the
product must be disconnected from the
supply network. Any adjustments,
replacements of parts, maintenance or
repair must be carried out only by technical
personnel authorized by Rohde & Schwarz.
Only original parts may be used for
replacing parts relevant to safety (e.g.
power switches, power transformers,
fuses). A safety test must always be
performed after parts relevant to safety
have been replaced (visual inspection, PE
conductor test, insulation resistance
measurement, leakage current
measurement, functional test).

3. As with all industrially manufactured goods,
the use of substances that induce an
allergic reaction (allergens, e.g. nickel)
such as aluminum cannot be generally
excluded. If you develop an allergic
reaction (such as a skin rash, frequent
sneezing, red eyes or respiratory
difficulties), consult a physician immediately
to determine the cause.

1171.0000.42-03.00 Sheet 2

Safety Instructions

4. If products/components are mechanically
and/or thermically processed in a manner
that goes beyond their intended use,
hazardous substances (heavy-metal dust
such as lead, beryllium, nickel) may be
released. For this reason, the product may
only be disassembled, e.g. for disposal
purposes, by specially trained personnel.
Improper disassembly may be hazardous to
your health. National waste disposal
regulations must be observed.

5. If handling the product yields hazardous
substances or fuels that must be disposed
of in a special way, e.g. coolants or engine
oils that must be replenished regularly, the
safety instructions of the manufacturer of
the hazardous substances or fuels and the
applicable regional waste disposal
regulations must be observed. Also
observe the relevant safety instructions in
the product documentation.

6. Depending on the function, certain products
such as RF radio equipment can produce
an elevated level of electromagnetic
radiation. Considering that unborn life
requires increased protection, pregnant
women should be protected by appropriate
measures. Persons with pacemakers may
also be endangered by electromagnetic
radiation. The employer/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
movable power cord and connector,
operation is permitted only on sockets with
earthing contact and protective earth
connection.

10. Intentionally breaking the protective earth
connection either in the feed line or in the

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

11. If the product has no power switch for
disconnection from the AC supply, the plug
of the connecting cable is regarded as the
disconnecting device. In such cases, it
must be ensured that the power plug is
easily reachable and accessible at all times
(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. Otherwise, this can
result in sparks, fire and/or injuries.

15. Do not overload any sockets, extension
cords or connector strips; doing so can
cause fire or electric shocks.

16. For measurements in circuits with voltages
V

> 30 V, suitable measures (e.g.

rms

appropriate measuring equipment, fusing,
current limiting, electrical separation,
insulation) should be taken to avoid any
hazards.

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

18. 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.

1171.0000.42-03.00 Sheet 3

Safety Instructions

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

20. For permanently installed equipment
without built-in fuses, circuit breakers or
similar protective devices, the supply circuit
must be fused in such a way that suitable
protection is provided for users and
products.

21. Do not insert any objects into the openings
in the housing that are not designed for this
purpose. Never pour any liquids onto or into
the housing. This can cause short circuits
inside the product and/or electric shocks,
fire or injuries.

22. Use suitable overvoltage protection to
ensure that no overvoltage (such as that
caused by a thunderstorm) can reach the
product. Otherwise the operating personnel
will be endangered by electric shocks.

23. Rohde & Schwarz products are not
protected against penetration of water,
unless otherwise specified (see also safety
instruction 1.). If this is not taken into
account, there exists the danger of electric
shock 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 or fire. Keep
batteries and storage batteries away from
children. Do not short-circuit batteries and
storage batteries.
If batteries or storage batteries are
improperly replaced, this can cause an
explosion (warning: lithium cells). Replace

the battery or storage battery only with the
matching Rohde & Schwarz type (see
spare parts list). Batteries and storage
batteries must be recycled and kept
separate from residual waste. Batteries and
storage batteries that contain lead, mercury
or cadmium are hazardous waste. Observe
the national regulations regarding waste
disposal and recycling.

28. Please be aware that in the event of a fire,
toxic substances (gases, liquids etc.) that
may be hazardous to your health may
escape from the product.

29. The product can be very heavy. Be careful
when moving it to avoid back or other
physical injuries.

30. Do not place the product on surfaces,
vehicles, cabinets or tables that for reasons
of weight or stability are unsuitable for this
purpose. Always follow the manufacturer's
installation instructions when installing the
product and fastening it to objects or
structures (e.g. walls and shelves).

31. Handles on the products are designed
exclusively for personnel to hold or carry
the product. It is therefore not permissible
to use handles for fastening the product to
or on means of transport such as cranes,
fork lifts, wagons, etc. The user is
responsible for securely fastening the
products to or on the means of transport
and for observing the safety regulations of
the manufacturer of the means of transport.
Noncompliance can result in personal injury
or material damage.

32. If you use the product in a vehicle, it is the
sole responsibility of the driver to drive the
vehicle safely. Adequately secure the
product in the vehicle to prevent injuries or
other damage in the event of an accident.
Never use the product in a moving vehicle if
doing so could distract the driver of the
vehicle. The driver is always responsible for
the safety of the vehicle. The manufacturer
assumes no responsibility for accidents or
collisions.

33. If a laser product (e.g. a CD/DVD drive) is
integrated in a Rohde & Schwarz product,
do not use any other settings or functions
than those described in the product
documentation. Otherwise this may be
hazardous to your health, since the laser
beam can cause irreversible damage to
your eyes. Never try to take such products
apart, and never look into the laser beam.

Other Softkeys

All other softkeys have different functions depending on the instrument state. Therefore, the labels (text)
on the softkeys will vary to reflect their current function. The state of the softkeys is indicated by
different appearances and colours, as follows:

Fig. 4 Setup of the softkey area

A softkey in its normal state, where its function is available, is coloured grey with a 3D border.

A softkey that is disabled, because its function is not

available, is coloured grey without a 3D border.
Softkeys may become disabled because of the state of the instrument or because other settings disable
the function associated with the softkey.

An active softkey (highlighted in green) is used when the softkey selects an item or view. For example,
the GATE SETTINGS softkey will be highlighted green when the Gate Settings pop-up dialog is
displayed.

A toggle softkey is used to change the value of a parameter that has only two states. Each press of the
softkey toggles the value of the parameter. The current parameter value is highlighted in green in the
lower half of the softkey label. For example, in the measurement results view, the DISPLAY softkey will
have either LIST or GRAPH highlighted in green depending on whether the results are currently
displayed as a list of measurement points or graphical trace(s).

When no function is assigned to a softkey then no softkey label will be shown.

The following measurements results are obtained in IQ measurement mode:

• Power vs Time (PVT)

• EVM vs Symbol

• EVM vs Carrier

Phase vs Preamble

•

• Frequency vs Preamble

• Spectrum Flatness

• Spectrum Group Delay

• Spectrum Flatness Adjacent Carrier Power Difference

• Spectrum FFT

• Constellation vs Symbol

• Conditional Cumulative Distribution Function (CCDF)

• Bit Stream

For each of the above results the Magnitude Capture Buffer display is available.

Fig. 12 Magnitude Capture Buffer Results

The Magnitude Capture buffer shows the complete range of captured data for the last sweep. All analyzed
bursts are identified with a green bar at the bottom of the Magnitude Capture buffer. Only those bursts which
matched the required criteria are marked with a green bar.
All IQ measurements process the same signal data and as such all IQ measurement results are available after
a single IQ measurement execution.
IQ measurements can be run in split screen mode (allowing both the Magnitude Capture Buffer Display
and the selected IQ measurement results to be displayed simultaneously) or in full screen mode (with
either the Magnitude Capture Buffer Display or the selected IQ measurement results displayed).
IQ measurements may be performed for RF or Baseband input.

the input signal.

Automatic level detection can be performed in one of two ways:

Pressing the AUTO LVL hot-key
Setting Auto Level in the General Settings view to ON.

Running the Automatic Level Detection by pressing the AUTO LVL hot-key allows the level detection to
be run at any time. Once the Automatic Level Detection has completed the trace is displayed in the
Magnitude Capture Buffer display.

Running the Automatic Level Detection by Setting Auto Level in the General Settings view to ON means
that an Automatic Level Detection measurement is executed before each main measurement sweep.
When running the Automatic Level Detection this way no trace for the Automatic Level Detection
measurement is displayed. This way of running the Automatic Level Detection will cause measurements
to run more slowly and as such it is recommended that Automatic Level Detection is only run in this way
when the speed of measurement is not important or when running continuous measurements are being
run with a signal which varies in level from one sweep to the next.
