following requirements apply to
Rohde & Schwarz products:
prescribed operating position is always with
the housing floor facing down, IP protection
2X, pollution severity 2, overvoltage
category 2, use only in enclosed spaces,
max. operation altitude max. 2000 m.
Unless specified otherwise in the data
sheet, a tolerance of ±10% shall apply to
the nominal voltage and of ±5% to the
nominal frequency.
2. Applicable local or national safety
regulations and rules for the prevention of
accidents must be observed in all work
performed. The product may be opened
only by authorized, specially trained
personnel. Prior to performing any work on
the product or opening the product, the
product must be disconnected from the

personnel authorized by Rohde & Schwarz.
Only original parts may be used for
replacing parts relevant to safety (e.g.
power switches, power transformers,
fuses). A safety test must always be
performed after parts relevant to safety
have been replaced (visual inspection, PE
conductor test, insulation resistance
measurement, leakage current
measurement, functional test).
3. As with all industrially manufactured goods,
the use of substances that induce an
allergic reaction (allergens, e.g. nickel)
such as aluminum cannot be generally
excluded. If you develop an allergic
reaction (such as a skin rash, frequent
sneezing, red eyes or respiratory
difficulties), consult a physician immediately
to determine the cause.
1171.0000.42-02.00 Sheet 2
Safety Instructions
4. If products/components are mechanically
and/or thermically processed in a manner
that goes beyond their intended use,
hazardous substances (heavy-metal dust
such as lead, beryllium, nickel) may be
released. For this reason, the product may
only be disassembled, e.g. for disposal
purposes, by specially trained personnel.
Improper disassembly may be hazardous to
your health. National waste disposal
regulations must be observed.
5. If handling the product yields hazardous
substances or fuels that must be disposed
of in a special way, e.g. coolants or engine
oils that must be replenished regularly, the
safety instructions of the manufacturer of
the hazardous substances or fuels and the
applicable regional waste disposal
regulations must be observed. Also
observe the relevant safety instructions in
the product documentation.
6. Depending on the function, certain products
such as RF radio equipment can produce
an elevated level of electromagnetic
radiation. Considering that unborn life
requires increased protection, pregnant
women should be protected by appropriate
measures. Persons with pacemakers may
also be endangered by electromagnetic
radiation. The employer is required to
assess workplaces where there is a special
risk of exposure to radiation and, if
necessary, take measures to avert the
danger.
7. Operating the products requires special
training and intense concentration. Make
certain that persons who use the products
are physically, mentally and emotionally fit
enough to handle operating the products;
otherwise injuries or material damage may
occur. It is the responsibility of the
employer to select suitable personnel for

result in the danger of an electric shock
from the product. If extension cords or
connector strips are implemented, they
must be checked on a regular basis to
ensure that they are safe to use.
11. If the product has no power switch for
disconnection from the AC supply, the plug
of the connecting cable is regarded as the
disconnecting device. In such cases, it
must be ensured that the power plug is
easily reachable and accessible at all times
(length of connecting cable approx. 2 m).
Functional or electronic switches are not
suitable for providing disconnection from
the AC supply. If products without power
switches are integrated in racks or systems,
a disconnecting device must be provided at
the system level.
12. Never use the product if the power cable is
damaged. By taking appropriate safety
measures and carefully laying the power
cable, ensure that the cable cannot be
damaged and that no one can be hurt by
e.g. tripping over the cable or suffering an
electric shock.
13. The product may be operated only from
TN/TT supply networks fused with max.
16 A.
14. Do not insert the plug into sockets that are
dusty or dirty. Insert the plug firmly and all
the way into the socket. Otherwise this can
result in sparks, fire and/or injuries.
15. Do not overload any sockets, extension
cords or connector strips; doing so can
cause fire or electric shocks.
16. For measurements in circuits with voltages
V
> 30 V, suitable measures (e.g.
rms
appropriate measuring equipment, fusing,
current limiting, electrical separation,
insulation) should be taken to avoid any
hazards.
17. Ensure that the connections with
information technology equipment comply
with IEC 950/EN 60950.
18. Never remove the cover or part of the
housing while you are operating the

R&S FSMU-W Information about the R&S FSQ
Tips and Special Tricks
Optimum Setting of the Reference Level and the Input Attenuator of the R&S FSQ
The accuracy and dynamic range that are possible when measuring with the R&S FSQ are dependent
primarily on proper settings of the input attenuator and the reference level. These parameters need to
be set to meet different criteria in different measurements. To make the instrument as easy to use as
possible while still producing the best possible measurement accuracy and dynamic range, a separate
automatic routine is provided in each measurement mode to set the R&S FSQ. This routine can be
called up in each measurement mode by pressing the
For swept measurements of the K72, the reference level is set optimally depending on the spacing from the
useful signal, e.g. when measuring the adjacent channel power or the spectrum emission mask.
Obtaining an Optimum Setting for the R&S FSQ’s Attenuator
The signal being measured passes directly from the input connector via the attenuator to the input mixer, i.e.
there is no filtering. This means that all of the spectral components contribute to the input level.
ADJUST REF LVL
softkey.
Fig. 1-3 Level relationships in the R&S FSQ
In terms of the optimum level at the input mixer, note the following:
• The higher the level at the input mixer, the greater the signal-to-noise ratio of the measurement.
• The lower the level at the input mixer, the greater the intermodulation ratio of the R&S FSQ.
• The maximum permissible level at the input mixer is +5 dBm; levels above this will produce an
OVLD (see the section “Error: The Instrument is Overdriven” on page 1.5).
• All of the spectral components of the input signal contribute to the input level.
For measurements in the code domain, the input attenuator is set so that the maximum level of the
input signal at the mixer is just below the +5 dBm threshold.
In this case, the value of the attenuation produced by the input attenuator is computed using the
following formula:
a
/ dB = P / dBm – 5 dB

Information about the R&S FSQ R&S FSMU-W
Obtaining an Optimum Setting for the R&S FSQ’s Reference Level
The signal being measured passes from the input mixer to the IF filter, where it is filtered with the set
resolution bandwidth. At the output of the IF filter, the signal is sampled with an A/D converter and digitally
processed in the following detector unit. By indicating the reference level, the gain in the IF filter is set so that
the A/D converter is just fully driven for an input signal level equal to the reference level.
In terms of the optimum reference level at the input mixer, note the following:
• The A/D converter may be overdriven only at times when the signal is not being evaluated.
• The higher the A/D converter is driven, the better the signal-to-noise ratio that will be obtained during
the measurement.
• Only the components of the input signal after filtering in the IF filter contribute to the drive of the A/D
converter.
• The optimum reference level for measurements in the code domain is 3 dB above the peak value of
the filtered input signal. The filter used in these measurements has a width of 10 MHz so that the
levels of the carrier being measured currently and the adjacent carriers must be taken into account.
Error: The Instrument is Not Triggering
During manual operation, the measurement is normally repeated continuously and the measurement
results are always kept up to date. The updating will be suspended while the instrument is waiting for a
trigger. This is indicated by a * at the top right edge of the screen:

Error: The Instrument is Overdriven
The instrument indicates an overdrive condition in the output screen using the IFOVL or OVLD indicator
as shown below:

Interpretation:
OVLD indicates that the input mixer is overdriven. => Increase the input attenuation
IFOVL indicates that the IF is overdriven. => Increase the reference level.

Tips and Special Tricks for Code Domain Measurements
Operation of the R&S FSQ when making measurements in the code domain does not differ significantly
in the different test cases. This section summarizes the tips and special tricks for all of the test cases
that apply to the code domain. The test cases are as follows:
Section Title
6 3GPP-FDD Transmitter Tests
6.2.2 CPICH power accuracy
6.3 Frequency error (together with EVM)
6.4.2 Power control steps
6.4.3 Power control dynamic range
6.4.4 Total power dynamic range (together with EVM)
6.7.1 Error vector magnitude (EVM)
6.7.2 Peak code domain error
Setting the Input Attenuator
The input attenuator is set automatically after you press the
ADUST REF LVL
softkey. The input attenuator
of the R&S FSQ is set so that the peak value of the input signal at the R&S FSQ’s mixer has a value of
less than +5 dBm.
For a multicarrier signal, the entire signal must be taken into account.
See also Chapter 6, section “Optimum Setting of the Reference Level and the Input Attenuator of the
R&S FSQ”, page 1.3.
Setting the Reference Level
The reference level is set automatically after you press the
The R&S FSQ’s reference level is set so as to just avoid overdriving the instrument, i.e. the reference
level is set approx. 3 dB above the peak value of the signal that is present after the IF filter. For a
multicarrier signal, the carrier to whose center frequency the R&S FSQ is set and its two neighbours all
make a contribution.
