Basic Safety Instructions

Electrical safety

If the information on electrical safety is not observed either at all to the extent necessary, electric shock,
fire and/or serious personal injury or death may occur.

1. Prior to switching on the product, always ensure 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

use of the product may have to be changed accordingly.

f

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

3. 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.

4. If the product does not have a power switch for disconnection from the AC supply network, the plug of
the connecting cable is regarded as the disconnecting device. In such cases, always ensure 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 network. If products without power switches are integrated into racks or systems, a
disconnecting device must be provided at the system level.

5. 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, you can ensure that the cable will not be damaged and that no one can be
hurt by, for example, tripping over the cable or suffering an electric shock.

6. 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).

7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the
socket. Otherwise, sparks that result in fire and/or injuries may occur.

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

9. For measurements in circuits with voltages V

> 30 V, suitable measures (e.g. appropriate

rms

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

10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial
computers, comply with the IEC60950-1/EN60950-1 or IEC61010-1/EN 61010-1 standards that apply
in each case.

11. 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.

12. 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 licensed electrician.

13. 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 anyone who has access to the product, as
well as the product itself, is adequately protected from injury or damage.

1171.0000.42-05.00 Page 3

Basic Safety Instructions

14. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of
lightning) can reach the product. Otherwise, the person operating the product will be exposed to the
danger of an electric shock.

15. Any object that is not designed to be placed in the openings of the housing must not be used for this
purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or injuries.

6. Unless specified otherwise, products are not liquid-proof (see also section "Operating states and

1

operating positions", item 1. Therefore, the equipment must be protected against penetration by
liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product
itself may be damaged, which can also lead to personal injury.

17. Never use the product under conditions in which condensation has formed or can form in or on the
product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water
increases the risk of electric shock.

18. Prior to cleaning the product, disconnect it completely from the power supply (e.g. AC supply network
or battery). Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such
as alcohol, acetone or diluents for cellulose lacquers.

Operation

1. Operating the products requires special training and intense concentration. Make sure that persons
who use the products are physically, mentally and emotionally fit enough to do so; otherwise, injuries
or material damage may occur. It is the responsibility of the employer/operator to select suitable
personnel for operating the products.

2. Before you move or transport the product, read and observe the section titled "Transport".

3. As with all industrially manufactured goods, the use of substances that induce an allergic reaction
(allergens) such as nickel cannot be generally excluded. If you develop an allergic reaction (such as a
skin rash, frequent sneezing, red eyes or respiratory difficulties) when using a Rohde & Schwarz
product, consult a physician immediately to determine the cause and to prevent health problems or
stress.

4. Before you start processing the product mechanically and/or thermally, or before you take it apart, be
sure to read and pay special attention to the section titled "Waste disposal", item 1.

5. Depending on the function, certain products such as RF radio equipment can produce an elevated
level of electromagnetic radiation. Considering that unborn babies require increased protection,
pregnant women must be protected by appropriate measures. Persons with pacemakers may also be
exposed to risks from electromagnetic radiation. The employer/operator must evaluate workplaces
where there is a special risk of exposure to radiation and, if necessary, take measures to avert the
potential danger.

6. Should a fire occur, the product may release hazardous substances (gases, fluids, etc.) that can
cause health problems. Therefore, suitable measures must be taken, e.g. protective masks and
protective clothing must be worn.

7. If a laser product (e.g. a CD/DVD drive) is integrated into a Rohde & Schwarz product, absolutely no
other settings or functions may be used as described in the product documentation. The objective is to
prevent personal injury (e.g. due to laser beams).

1171.0000.42-05.00 Page 4

Basic Safety Instructions

Repair and service

1. The product may be opened only by authorized, specially trained personnel. Before any work is

Functional Description - Block Diagram

1.3 Functional Description - Block Diagram

The Adjacent Channel Power measurement is performed in the spectrum analyzer
operating mode of the analyzer. For this test case the complete frequency band is
scanned using a sequence of zero span measurements.

ll other test cases are based on a digital I/Q demodulator which determines the

A
temporal characteristics of power and frequency. The output data of the demodulator
are the basis for calculation of all relevant measurement results like modulation
characteristics or output power. The demodulator reaches a maximum in accuracy and
temperature stability by sampling the IF signal and converting it digitally down into the
base band (I/Q area).

The measurements are performed by passing the following signal processing steps:

• LAP (Lower Address Part) trigger detection

• Resampling

• Channel filtering

• Automated packet and bit pattern detection

• Limit check

• Parallel display of measurement curves and numeric results on the screen

Fig. 1 shows the analyzer hardware from the IF to the processor. The analog IF filter is
the resolution filter of the spectrum analyzer, which can be selected in a range from
300 kHz to 10 MHz. The A/D converter samples the 20.4 MHz IF signal with a
sampling frequency of 32 MHz.
Low pass filtering is performed after the signal has been down-converted into the
complex base band and the data rate is reduced in the sequence. The amount of
decimation depends on the selected oversampling factor = points / symbol. The default
setting is 4, resulting in a 4 MHz sampling rate.
The resulting I/Q data are stored in a memory of 128 k words (FSU 512 k words) for I

and Q respectively. The hardware trigger (external or IF power) controls the memory
access.

Further Characteristics

1.4 Further Characteristics

1.4.1 Bandwidths

The Bluetooth RF Specification defines a minimal bandwidth of 3 MHz. This
requirement is related to the standard gaussian filters as normally used by spectrum
analyzers. As the amplitude characteristics of these filters is not flat a bandwidth must
be selected that is significantly higher than the bandwidth of the signal under test. The
3 MHz filter causes an error in frequency deviation of about 4% as soon as a 0101
symbol sequence is used. Therefore an IF bandwidth of 10 MHz is highly
recommended for this measurement and set up as the default value. The digital
bandwidth is smaller and depends on the selected oversampling factor = points /
symbol. With the default setting of 4 the digital bandwidth is 3 MHz. This digital filter
has a flat amplitude characteristics and does not affect the frequency deviation of the
signal.

1.4.2 Optional Measurement Filter (Meas Filter On)

The RF Specification allows high distortion power in the first adjacent channels. The 3
MHz filter does not suppress this kind of distortion, which leads to a high interference
in modulation. Therefore a precise measurement of the frequency deviation is not
possible.
In order to obtain correct deviation results the analyzer supplies an optional filter
whose pass band is only appropriate for the channel to measure. The Bluetooth
spectrum has a bandwidth of 1 MHz. The filter is flat within 1.04 MHz (ripple: only 0.02
dB) and has steep edges. This measurement filter is not dependent on the selection of
the points / symbol value. As a result the displayed deviation value will increase by

3.2%, but without the filter the displayed deviation value can increase dramatically due
to interference from adjacent channels. Generally the result will be more precise, if the
displayed deviation is lower with filtering than without filtering. In these cases the
inaccuracy caused by the adjacent channel interference is higher than the systematic
inaccuracy caused by the filter.

the symbol length of 1 Qs)

Sampling rate

According to the RF Test Specification an oversampling factor of 4 is required at
minimum. On the analyzer this oversampling factor can be selected as "Points per
Symbol" in a range from 2 to 32. The default value is 4.

Although possible a value > 4 is not recommended. It increases the measurement time
due to the extended calculation effort. Additionally the resulting bandwidth will be larger
than required, which leads to lower measurement accuracy, unless the optional
measurement filter (Meas Filter On) is used as described in chapter "Bandwidths".

The analyzer uses a phase shifter in order to move the samples to the zero
trespassing points. As a result there is one sample per symbol time, which is especially
important for a 0101 symbol sequence in order to obtain the precise value for the peak
frequency deviation.

Sampling times before Phase Shifter Sampling times after Phase Shifter

Fig. 3 Operation of the Phase Shifter

Advantages of the Phase Shifter:

• No jitter with low sampling rates

• With one sample per zero trespassing point there is always a sample in the middle

of the bit length. Therefore the maximum values in the frequency deviation of 0101
bit patterns can be detected precisely also with low sampling rates.

• The immunity to interference when determining the data bits is improved.

• Higher suppression of the distortion during peak detection.

Further Characteristics

1.4.4 Determining Average or Max/Min Values during several Sweeps (= Bursts)

These functions are very useful in order to obtain more stable results or to find
sporadic spurious signals not included in every burst. In many cases the RF Test
Specification defines measurements over a 10 burst period.

The number of measurements can be selected using function Sweep Count , thus
adapting the measurement to the individual requirements.

When using function Single Sweep the calculation of average or maximum / minimum
values is performed over a well-defined number of sweeps (= Sweep Count).

Continuous Sweep hingegen liefert eine fortlaufende Mittelwertbildung und
Extremwertbildung über die gesamte Messzeit.

Modulation measurements

are performed using trace mode Clear Write.

In contrast to this Continuous Sweep yields continuous averaging and calculation of
maximum / minimum values over the whole measurement time.

With Continuous Sweep a "live" display is obtained, which allows e.g. an instant view
of changes during alignment of a DUT.

Power measurements

are performed using trace mode Maxhold in relation with the
defined measurement time. The measurement time is selected in a way that makes
sure that always one complete burst is acquired. In this case several sweeps are
combined to one trace, before this result trace is evaluated.

will be calculated based on this summarized
trace.

Please note that the above functions may not be mixed up with the detectors of the
instrument:

• Detectors combine the measurement data obtained by oversampling to one pixel

on the screen. The kind of combination (Max Peak, Min Peak, Average, RMS) can
be selected.

Software Manual 1157.2597.42 - 03 12

S-K8 Introduction

Further Characteristics

• The trace functions affect complete measurement curves: A resulting curve is

calculated from several subsequent sweeps. The method of calculation
(Average, Maxhold, Minhold) can be selected here as well.

Thus the detector is the arithmetic rule for how sample data collected with a high data
rate are combined to the pixel data of one individual measurement curve, whereas the
trace mode is the rule of how samples taken from several measurement curves are to
be combined to a new resulting curve.

For the ACP measurement the Average detector is fixed.

1.4.5 Trigger Concepts

As the DUT (Device Under Test) uses frequency hopping, a trigger method is
necessary for two reasons:

1. a measurement is only possible during the period of time, when there is a Tx signal

(burst) at the frequency under request.

2. In order to determine the modulation characteristics correctly a synchronization

with the preamble of the signal must be supplied.

With selection Find Sync = On the synchronization is supplied towards the 64 bit sync
word. For this purpose in a first step a burst is searched automatically within the RF
signal, or, if selected, the external trigger or the IF power trigger will be used in order
to determine the burst position.

In a second step the sync word position is searched by correlation of the signal with
the sync word defined in the initialization phase. The corellation is performed directly
with the FM signal, not with the data bits, which are only available after the phase
shifter has been processed. The find burst process will be continued as long as no
sync word has been found.

After the position of the sync word has been determined the position of the p0 bit will
be calculated from the average value of all zero trespassing points, as defined in the
RF test specification. Finally the samples will be moved in a way that each sample
matches one zero trespassing point (phase shifting).

The only measurement possible without synchronization is the Output Power
Measurement. The specified measurement time is 20% to 80% of the burst length.
Without synchronization the burst length is defined via the -3dB points of the power
curve. With synchronization the burst starts with the p0 bit. Therefore varying
measurement results are possible if the power of the EUT is not constant within the
burst.

In order to supply stable synchronization the EUT must be operated in reduced
hopping mode. The EUT is only allowed to toggle between two frequencies, because
otherwise the repetition time for the same frequency would become higher than the
record length.

If the test environment supplies an external trigger which marks the channel to be
measured a synchronization is also possible with normal hopping operation.

CHANNEL

The softkey CHANNEL opens the editor for the index of the Tx channel. The range of
valid values is dependent on the locally available frequency band.

diting the channel number is in principle equal to changing the center frequency. The

E
major difference is that the center frequency editor does not limit frequency values to
the available frequency band, which means that values outside the frequency band
and between the discrete channels can be selected.
As soon as the channel number editor is opened after the center frequency has been
changed, the center frequency will be rounded to the nearest channel number.

The channel number determines the center frequency for the following measurements:

• Output Power

• Modulation Characteristics

• Initial Carrier Frequency Tolerance

• Carrier Frequency Drift

• Relative Transmit Power (EDR)

• Carrier Frequency Stability and Modulation Accurracy (EDR)

• Differential Phase Encoding (EDR)

The center frequencies of the other measurements are independent of the active
frequency channel (see menu FREQ).

The available value range for the channel number is dependent on the selected
country. It is defined as follows:

USA, Europe (outside France): 0..78
France: 0..22

The formula for calculating the center frequencies is as follows:

USA, Europe (outside France): f = 2402 + k MHz with k = 0..78
France: f = 2454 + k MHz with k = 0..22

The default setting is channel number 0.

The following statement is equally valid for all groups of measurement functions:

The softkeys RES BW AUTO or IF BW AUTO select the bandwidths according to the
values defined in the RF Test Specification.

Value range and default settings of measurement time / sweep time are described in
chapter "Hardkey: MEAS" together with the corresponding softkeys MEAS TIME /
SWEEP TIME.

The function of the softkeys VIDEO BW MANUAL / AUTO, COUPLING RATIO and
DEFAULT COUPLING is identical to the basic instrument. Please refer to the
corresponding chapters of the basic instrument operating manual.

Please note that the corresponding GPIB commands are placed in the CONF:BTO
subsystem.

MEAS FILTER

The softkey MEAS FILTER activates a filter that limits the bandwidth for the modulation
measurements.

The filter is flat within 1.04 MHz (ripple: only 0.02 dB) and has steep slopes outside this
area. Minimum attenuation in the transition band. The filter has the following
characteristics:

• Passband Ripple up to ±550 kHz < 0.5 dB (peak to peak)

• Minimum attenuation in the transition band
± 650 kHz:  3 dB
± 1 MHz:  14 dB
± 2 MHz:  44 dB

Remote: SENS:DDEM:FILT:MEAS OFF | BTO

The MEAS FILTER softkey is only available if one of the following measurements has
been selected: MODULATION CARR, INIT CARR FREQ TOL, CARR FREQ DRIFT.

3.11 Starting Measurements - Hardkey SWEEP

In the BLUETOOTH operating mode the hardkey SWEEP is used for direct entry into
the measurement menu of the currently selected measurement.. The "deviation" via
the key sequence MEAS + submenu selection is not necessary in this case.

The functions of the individual softkeys are described in the corresponding chapter of
the submenu of hardkey MEAS.

Please note that the corresponding GPIB commands are placed in the CONF:BTO
subsystem.

Trigger Settings - Hardkey TRIG

The IF POWER softkey activates triggering of the measurement via signals which are
outside the measurement channel.

For this purpose, the R&S FSP uses a level detector at the second intermediate
frequency. The trigger level can be selected in a range between –30 dBm and -10 dBm
at the input mixer.

he R&S FSU also uses a level detector at the second intermediate frequency. The

T
trigger level in this case can be selected in a range between –50 dBm and -10 dBm at
the input mixer.

The resulting trigger level at the RF input is calculated via the following formula:

eampGainRFAttMixerlevelSignalInputeampGainRFAttMixerlevel PrPr

maxmin

++

The bandwidth at the intermediate frequency is 10 MHz for the FSP and 50 MHz for
the FSU. The analyzer is triggered as soon as the trigger threshold is exceeded within
a 5 MHz range (FSU: 25 MHz range) around the selected frequency (= start frequency
in the frequency sweep).. Thus, the measurement of spurious emissions, e.g. for
pulsed carriers, is possible even when the carrier lies outside the selected frequency
span.

Remote: TRIG:SOUR IFP

RF POWER

The RF POWER softkey activates triggering of the measurement via signals which are
outside the measurement channel.

For this purpose, the analyzer uses a level detector at the second intermediate
frequency. The trigger level can be selected in a range between –50 dBm and -10 dBm
at the input mixer.

The resulting trigger level at the RF input is calculated via the following formula:

eampGainRFAttMixerlevelSignalInputeampGainRFAttMixerlevel PrPr

maxmin

++

The bandwidth at the intermediate frequency is 80 MHz. The analyzer is triggered as
soon as the trigger threshold is exceeded within a 40 MHz range around the selected
frequency (= start frequency in the frequency sweep).. Thus, the measurement of
spurious emissions, e.g. for pulsed carriers, is possible even when the carrier lies
outside the selected frequency span.

This function is only available with the R&S FSP and only with option TV- und RF­Trigger R&S FSP-B6.

The "Description of commands" section includes the new commands valid especially
for the R&S FS-K8 application, as well as modified commands of the basic instrument,
as far as they are used by the R&S FS-K8 option. commands which are used equally
in basic instrument and option K8 are marked accordingly in the operating manual of
the basic instrument.

In the description of measurements in Chapter 3, the corresponding IEC/IEEE-bus
commands are stated for each softkey.

Measurements for operating mode BLUETOOTH are always performed in screen A.
Therefore all commands which use the numeric suffix for selection of the screen must
be supplied with either the numeric suffix 1 (e.g. CALCulate1) or without numeric suffix
(e.g. CALCulate).

MCH), Initial Carrier Frequency Tolerance (CONF:BTO:MEAS ICFT) and Carrier
Frequency Drift (CONF:BTO:MEAS CFDR) is common to all three measurements.
For all other Bluetooth measurements the setting is only valid for the currently active
measurement (see command CONF:BTO:MEAS).
This command is not available with active adjacent channel power measurement
(command: CONF:BTO:MEAS ACLR).
