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).

R&S FSQ-K110 General Information

1 General Information

The Rohde & Schwarz FS-K110 application extends the functionality of the R&S FSQ or R&S FSU
spectrum analyzer to enable TETRA Release 2 (TEDS) measurements according to the standards [1]
and [2] (please refer to page 124).

This manual supports the user in working with R&S FS-K110. It aids the preparation, execution and
evaluation of a measurement and gives many helpful hints and examples.

For the user wanting to make a quick start to using R&S FS-K110, the Quick Start Guide section below
works step-by-step through an ordinary measurement. The remainder of this section describes all of the
basic information about how the R&S FS-K110 application works, without covering measurements in
detail. A detailed description of all measurement modes, settings and results can be found in section 2.
Section 4 covers remote control operation of R&S FS-K110.

This section covers the following subjects:

Introduction to R&S FS-K110 measurements

General Information R&S FSQ-K110

Introduction to R&S FS-K110 TETRA2 Measurements

The use of an R&S FSQ or R&S FSU spectrum analyzer with its high sensitivity enables the accurate and
reproducible measurement of a TETRA Release II Device Under Test (DUT).

• R&S FS-K110 Supports measurements of the physical layer of TETRA Release II (ETSI EN 300
392-2 V3.2.1) TEDS signals that are listed in Fehler! Verweisquelle konnte nicht gefunden

• R&S FS-K110 does not support TETRA Release 1 signals (phase modulation). Those signals can
be measured with the base system spectrum analyzer respectively the Vector Signal Analyzer
option FS-K70.

• All measurements are based on the same buffer of captured IQ data, no swept measurements.

• All measurements are done this way:

- The specified slots are searched in the captured IQ data.

- If suitable slots are found they are demodulated and the exact slot start and end is calculated
internally. Modulation errors are calculated.

- Suitable ranges from that IQ data are then cut out exactly aligned to the slot’s timing. Those
ranges of IQ data are processed according to the different implemented measurements. Results
are shown.

• Not only the measurement(s) currently seen on the display, but ALL measurements the application
offers are always calculated on each found slot in the background.
This means, if "EVM versus Symbols” for example is selected as active measurement and one
RUN SGL measurement that demodulates 100 slots is started, it is clear that afterwards the
Min/Max/Average/Current traces of "EVM versus symbols” calculated of 100 slots can be seen on
the screen. But after this single sweep the application also allows the user to switch to any other
measurement and see the "Phase Error versus Symbols”, "Magnitude Error versus Symbols”, etc,
results of the same 100 slots.

Modulation measurements:

– Constellation diagram (selectable subcarrier and selectable symbol type)
– Constellation diagram per subcarrier
– IQ offset and IQ imbalance
– Quadrature error
– Amplitude droop
– Carrier frequency error
– Error Vector Magnitude (EVM) per subcarrier or symbol
– EVM of whole slot. For all symbols or for certain combinations of symbol types
– Magnitude Error per symbol and for whole slot.

1309.9680.42 8 E-3

R&S FSQ-K110 General Information

– Phase Error per symbol and for whole slot.

• Power versus Time

• Adjacent Channel Power (Absolute and Relative) due to Modulation

• Adjacent Channel Power (Absolute and Relative) due to Transients

• FFT during found slots.

• Data symbol and Header symbol bit information

• Capture time selectable up to 1.53 seconds, multiple sweeps possible for large number of bursts

R&S FSQ-K110 General Information

Trouble-shooting guide

Find some hints that should help to make measurements run smoothly.

In case no slots or not all slots are found

• Correct slot type set?
Check this in the dialog "Demod settings”.

• Correct number of sub carriers set?
Check using the measurement "Spectrum FFT” and in dialog "Demod settings”.

• Signal level set much too high or much too low?
Check using the measurement "Magnitude Capture Display”: Peak power should be near to the
"Reference Level” but not above.
Check if the warnings "IFOVLD” or "OVLD” appears.

• Capture time too short?
There must be one or more slots in the capture buffer and additionally there must be some extra
time before and after a slot, otherwise it is not accepted!
If not sure, increase the capture time.
Check using the measurement "Magnitude Capture Display”.

• Parameter "Swap IQ” set the same as in DUT?
Toggle the parameter "Swap IQ” in dialog "Demod settings”.

• Correct frequency set?
Do the frequencies of DUT and FS-K110 application match? Check the signal’s spectrum using the
measurement "Spectrum FFT” or "ACP due to Modulation”.

• Demodulator lock range too small?
If the frequency error of the DUT is unknown or known to be rather high it is recommended to
increase the parameter "Max Carrier Offset”, page 79.
Check the signals spectrum using the measurement "Spectrum FFT” or "ACP due to Modulation”.

• In case you use the analog base band input of the instrument:

– Only one cable connected?
– Cables interchanged?
– Balanced / unbalanced?
– The low pass filter of the analog base band input (refer to page 76) must be switched on if the signal

has high frequency components (above about 40 MHz). Otherwise aliasing occurs.

• In case you use the digital Baseband input of the instrument:

– Cable is connected to the socket “IQ DATA IN” (not “IQ DATA OUT”) of the analyzer and to the socket

“BASEBAND DIGITAL OUT” (not “BASEBAND DIGITAL IN”) of the R&S SMU (in case this vector
signal generator is used)?

– Same parameter “digital input sampling rate” set in receiver (analyzer) and transmitter?
– If the R&S EX-IQ-Box is used to interface a customer specific digital Baseband format to the format

needed at the digital Baseband input of the R&S analyzer: Is the R&S EX-IQ-Box configured in the
correct way?

– Remember that the center frequency is set to 0 Hz for digital Baseband input.
– Remember that no trigger modes are supported for digital Baseband input.

1309.9680.42 13 E-3

General Information R&S FSQ-K110

Hint for usage of digital Baseband inputs:

his R&S SMU screenshot shows one possible

T
configuration for the scenario, that an R&S SMU vector
signal generator (with digital Baseband output installed) is
directly connected to an analyzer (with digital Baseband
input installed) running the R&S FS-K110.

• Connect the devices using the digital Baseband
cable and the correct sockets as described above.

• Switch digital Baseband output of R&S SMU on (in
the overview diagram the block is labelled
AWGN/IMP).

• Switch R&S FS-K110 parameter Input to IQ digital
(dialog general settings).

• Set R&S SMU parameter Source to User Defined

• Set R&S FS-K110 parameter Digital Input Sample

Rate to let’s say 2 MHz (large enough for TEDS
signals).

• Set R&S SMU parameter Value exactly the same
as the R&S FS-K110 parameter Digital Input
Sampling Rate.

• Press Run Single hotkey of R&S FS-K110.

1309.9680.42 14 E-3

R&S FSQ-K110 General Information

In case that slots are found but the EVM is bad

• Correct payload symbol QAM type set?
Check using the measurement "`Constellation vs. Symbols” and "Symbols to plot” set to "Data”.

• Signal level set too high or much too low?
Check using the measurement "Magnitude Capture Display”: Peak power should be rather close to
the "Reference Level” but never above it.
Or check using the measurement "Result list”: Enter the shown measurement value "Maximum of
Burst power” minus 1 or 2 dB contingency reserve as parameter "Signal Level”

• Instrument calibrated?
If red warning "UNCAL” appears switch back to the base system (softkey "SPECTRUM”) and start a
calibration (hard key "CAL”).

• Does the transmitter send PRBS data?
The demodulator needs pseudo-random data (data symbols) in all subcarriers. This means, a too
regular bit pattern (on the physical layer, after channel coding in DUT) might cause the demodulator
to fail or to be unstable.

• External Reference?
If the instrument was told to use an external reference (hardkey SETUP in the base system) then
make sure to supply in a valid reference signal with the correct frequency). Otherwise a red warning
"EXTREF” will show up on the screen.

• Signal has high amplitude droop?
If e.g. thermal effects in the power ramping stage cause an exponential amplitude decay or
increase over the slot duration, then make sure to activate "Compensate Amplitude Droop”, please
refer to page 80.

• Fading?
If the signal experiences multi-path effects, then make sure to activate "Pilot Tracking”, please refer
to page 80.

• Sync symbols according to the standard?
Check using the measurement "Constellation vs. Symbols” and softkey "Symbols to plot”.

Slot search details

his chapter gives some information how the application searches for TEDS slots.

T

• The slot search searches in the whole captured IQ data. The length is defined by parameter Capture
Time, page 71.

• The slot search only accepts (and therefore the application only demodulates) slots which have the
selected type (NDB / RAB / NUB / CB) and at the same time
/ 32 / 48), please refer to parameters "Slot Type” on page 79 and "Channel Bandwidth” on page 67.

• Other slots are ignored, with one exception: 2 different slot types that use exactly the same sync and
pilot symbols cannot be distinguished. This is the case for RAB slots with 8 subcarriers versus CB
slots with 8 subcarriers.

• If the sync and pilot symbols of a certain slot are the same or similar as the sync and pilot symbols in
the inner part of a wider slot, the slot search will also accept both kind of slots. This is the case for
NDB with 8 subcarriers versus NDB with 16, 32 or 48 subcarriers.

• The payload symbol modulation type (4 QAM, 16 QAM, 64 QAM) is NOT a parameter that affects
the slot search. It should nevertheless be set correctly because it affects the demodulation process
and the measured results. Even measurements that use no demodulation (like "Spectrum FFT”)
might be affected indirectly, because they depend on getting a reliable slot start and slot end
information from the demodulator.

the selected number of carriers (8 / 16

• The time slots used can be as the standard [2] specifies, but they need not. This means the interval
between 2 slots can be arbitrary.

• The slot search does not require an increase of the signal’s amplitude during the slot duration. Slot
search does not depend on power ramping.

• Slots at the very start and the very end of the capture buffer are always declined, because some
measurements like ACP due to Transients need some time before and after the slot for measuring.

• Strong signals in adjacent channels can disturb the slot search if the parameter "Max Carrier Offset”
on page 79 is set too high. It must then be decreased.

• A very low SNR, excessive noise, multipath or distortion can make the slot search unreliable.

• The slot search requires that the signal is as specified in standard [2], especially the sync and pilot

symbols.

• The frequency offsets of the slots to measure must not be greater than the nominal center frequency
plus or minus the demodulator lock range the user has selected (please refer to parameter "Max
Carrier Offset” on page 79). Otherwise the slots will not be detected at all or at least not reliably.

R&S FSQ-K110 General Information

Navigation

This section deals with navigation within the option. Navigation here is taken to mean all forms of interaction
with the option except for remote control. The different methods of interacting with the option are:

• Hotkeys

• Softkeys

• Hardkeys

• Numeric Keypad

• Roll-key

• Cursor Keys

• External Keyboard

• Mouse

Hotkeys

Hotkeys are allocated to the seven keys at the bottom edge of the screen. On initial start-up of the R&S
FS-K110 option, the hotkeys provided are shown in Fig. 1. These hotkeys are present at all times once
the option has been started.

General Information R&S FSQ-K110

These hotkeys perform the following operations:

The SPECTRUM hotkey exits the R&S FS-K110 option & returns to the spectrum
analyzer with most previous settings restored.

TETRA2

AUTO LVL

RUN SGL

RUN CONT

REFRESH

SCREEN [A|B]

The TETRA2 hotkey returns the user to the main measurement menu of R&S FS-K110,
where measurement results can be seen. All settings views and pop-up dialogs are
removed from the display, and the default softkey menu is displayed

The TETRA2 hotkey remains green whenever R&S FS-K110 is active

The AUTO LVL hotkey is currently not available yet.

The RUN SGL hotkey starts the selected measurement in single sweep mode. This
means that the measurement will stop if either one capture buffer is processed or if the
number of slots set by the parameter Number of slots to analyze (cf. dialog Demod
Settings) is reached.
If another measurement (such as a continuous sweep measurement) is running while
you press this hotkey, the running measurement will be completed and stopped.

The RUN CONT hotkey starts the selected measurement in continuous sweep mode.
This means that the measurement will never stop. The parameter Number of slots to
analyze (cf. dialog Demod Settings) will determine when MIN/MAX/AVG statistics of all
measurements will be reset.
Pressing the RUN CONT hotkey while a continuous sweep measurement is running
causes the measurement to be stopped (aborted).

The REFRESH hotkey enables repeatedly recalculation using old IQ data and the
currently set parameters (general settings/demod settings). It triggers no IQ data
capturing.
Example: The user has done a RUN SGL measurement with certain settings.
Afterwards he wants to try which results are calculated with exactly the same old IQ
data but other settings. So the steps would be:

• RUN SGL, afterwards look at results.

• Cange some settings, press REFRESH, look at how results changed.

• Cange some settings, press REFRESH, look at how results changed and so on.

The REFRESH hotkey is only available after a RUN SGL.
Pressing the REFRESH hotkey disables the parameter Number of slots to analyze (cf.
dialog Demod Settings) in case it was active.
REFRESH does of course not make sense after changing parameters that affect
capturing of IQ data (center frequency, RF input vs digital or analog Baseband input,
etc.)

The SCREEN [A|B] hotkey selects the specified screen as the active screen. This is
e.g. important to do before operating markers.

In full screen mode (cf. hotkey DISP) pressing the SCREEN [A|B] hotkey will display the
specified screen.

After Pressing the SCREEN [A|B] hotkey the label displayed in the hotkey is changed e.g.
after pressing the SCREEN A hotkey the label of the hotkey is changed to SCREEN B. The
label indicates which screen will become the active screen after the hotkey is pressed.

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 DEMOD SETTINGS softkey will be highlighted green when the Demod Settings view 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.

This section contains a detailed description of all measurement modes, settings & results. It covers the
following subjects:

• Measurement modes

• Running measurements

• Measurement results

• General settings

• Demodulation settings

• Marker settings

• General hints about measurements

Running measurements

To start a measurement, press the RUN SGL hotkey (single) or RUN CONT hotkey (continuous).

A single measurement (RUN SGL) will complete once the requested number of bursts have been
obtained (parameter is active) or a single sweep (i.e. one capture buffer) has been completed.
When a measurement is completed in continuous mode (RUN CONT) then a new measurement will be
started.

Note that if the RUN SGL hotkey is pressed while a current measurement is running, that measurement
will be aborted, and the Status Bar will display, "Measurement Aborted”.

During a measurement, the text "Running..." is displayed in the Status Bar at the bottom of the screen.
After successful completion of a single measurement, the Status Bar will display "Measurement
Complete”

Magnitude Capture Display (Available From Multiple Measurements)

he Magnitude Capture Display is special in that it is mostly not used as an independent measurement.

T
Instead it is mostly part of the following measurements:

• EVM vs Symbol

• EVM vs Carrier

• Magnitude Error

• Phase Error

• Spectrum FFT

• Constellation vs Symbol

• Constellation vs Carrier

• Bit Stream

Normally (split screen mode) any of these measurements shows Magnitude Capture Display in the
upper half of the screen.

But by using the hotkey SCREEN [A|B] and hardkey DISP the magnitude capture display can as well be
shown in full screen mode (as shown below) or it can be put into the background and is not visible any
more.

The Magnitude Capture Display shows the complete range of captured data for the current sweep. All
analyzed bursts are identified with a green bar at the bottom of the Magnitude Capture Display. Information

R&S FSQ-K110 Measurements & Settings

about which slots are found or declined can be found in chapter "Slot search details” on page 16.

lease note that slots at the very start and end of the buffer are declined, because the internal signal

P
processing needs some additional symbols before and after a slot.

Note that the R&S FS-K110 captures IQ data with a bandwidth much larger than the nominal set channel

andwidth. As a consequence the Magnitude Capture display will show not only the power in the TX

b
channel, but also in the neighboring channels (which should ideally be inactive).

Measurements can be run in split screen mode (allowing both the Magnitude Capture Display and the
selected IQ measurement results to be displayed simultaneously) or in full screen mode (with either the
Magnitude Capture display or the selected IQ measurement results displayed).

The horizontal top line of the Capture Display marks that level which is called Reference Level. In the
above example it is -20dBm. All input levels above this level may cause distortion, clipping and
warnings like "IFOVLD” or "OVLD” on the screen. Avoid these situations by setting the parameter

• Signal Level (RF) (refer to page 68) for RF input or

• Signal Level (Baseband) (refer to page 69) for analog Baseband input

correctly.

Exception: For digital Baseband input there is no risk of overloading the analyzer’s hardware. The
horizontal top line of Capture display marks the maximum input level the digital Baseband input can
have.

Measurements may be performed for RF or analog Baseband or digital Baseband input. Please refer to
parameter Input Settings on page 74. The unit of the parameter Reference Level (horizontal top line of
the Magnitude Capture Display) will change between “dBm” (RF input operation) and “Volt” (analog or
digital Baseband input operation).
In case of analog or digital Baseband input operation the Magnitude Capture Display trace shows the
relation (in decibel ) of the input signal to the Reference Level’s voltage. But the marker and the trace
delivered in SCPI operation have the measurement unit “Volt” (no logarithm).

The Magnitude Capture Display measurement is good for checking:

• Is there a signal at all?

• Has the signal the correct power? The maximum power should be near to the Reference Level, but

never above! Too low levels increase the SNR.

• Have the bursts the assumed length?

• Does the slot search algorithm of the R&S FS-K110 accept all slots?

• Are there single burst or consecutive ones?

• Does triggering work as excepted (cf. Trigger Settings on page 72)

• How many burst are there in the Capture Buffer (cf. parameter Capture Time on page 71)

For detailed information about the results please refer to chapter "

Results of Power versus Time” on page 118.

The signal around every found slot ( slot or sub-slot duration plus 6 symbol durations
before and after) is first compensated for its frequency error and then filtered by a quasi­rectangular low pass filter with a bandwidth of 25 KHz / 50 KHz / 100 KHz / 150 KHz
depending on the set channel bandwidth.
The filter’s output can be exactly aligned to the slot’s timing, because the application
knows the symbol instants after demodulation.

The lower half of the diagram shows the power versus time traces. The vertical lines
show the symbol instants S1 (x axis is 0 there) and S14 (or S31 or S34), i.e. the first and
last symbols.

Other vertical lines show T1 and T3, times that are defined in figure 6.4 of [2].

Fig. 19 Spectrum FFT Results (example)

Two cases must be distinguished:

1. At least one slot is found in the currently used IQ data:

The signal around every found slot (slot or sub-slot duration plus 6 symbol

durations before and after) is multiplied with a window function and processed by

an FFT ("Welch method”). All these single FFT results contribute to the total

Min/Max/AVG result statistic of the measurement. At the end of the measurement a

Min/Max/Avg and a current (i.e. last found slot) trace will be shown.

2. No slot at all is found in the currently used IQ data:

The same FFT processing as described before is done, but on the whole currently

captured IQ data. The FFT result is show as "current trace”, but it does NOT

contribute to Min/Max/Avg result traces. This trace should just give an overview.

The FFT span depends on the selected channel bandwidth (cf. parameter Channel
Bandwidth, page 67). Note that measurement "ACP Modulation” (page 51) does show
exactly the same FFT result, but a wider span.
The Resolution Bandwidth (RBW) is in any case equal to 300 Hz.
The x axis frequencies are relative to the nominal set center frequency (cf. parameter

Remote: :CONF:BURS:SPEC:ACPR:MOD

Fig. 20 ACP Due to Modulation Results (example)

Every time a slot in the TX channel is found, the raw input signal around this slot is
filtered with a RRC filter at different offset frequencies.
The RRC filter is as defined in [2]:

• Roll-off: 0.35

• Design symbol rate: 18 KHz

• Filter’s frequency offset relative to the TX channel’s nominal center frequency

depends on the set signal bandwidth and the offset channel index.

The automatically set ACP parameters can be checked in the upper half of Fig. 20 or in
chapter "ACP (Modulation+Transients) Settings” on page 81. There is the TX channel
and 3 offset channels above and 3 below.

The application is able to exactly cut out the useful part (i.e. first to last symbol instant)
from the RRC-filters’ outputs, because a demodulation took place. The application
calculates the mean power during the useful part of each slot found in the TX channel.

For each offset channel the maximum measured absolute mean power during the
useful part is drawn as a green bar in the lower part of the diagram (cf. Fig. 20).
Exception: For the TX channel the bar represents the maximum "Reference Power”
measured in it (cf. Formula 50).

Measurements & Settings R&S FSQ-K110

The Summary Table in the upper half of the diagram shows the absolute and relative

owers in all 6 offset channels, where "relative” means that a power in the adjacent

p
channel is related to the Reference Power (cf. Formula 50) measured in the TX­channel by the demodulator for the same slot.

For more details about the trace please refer to Formula 67 on page 117.
For more details about the result table please refer to Fig. 20 on page 51.

Please note that the switch ACP Display, page 82, selects if the “Current” & “Max” or
the “Average”and “Max” results are shown in the table.

The FFT trace shown in the lower half of the diagram is the same as the one of
measurement Spectrum FFT (page 49), except that the span is wider. The FFT trace
serves only as a signal overview, no measurement results are derived from it! The FFT
trace is therefore even drawn if no slots are found. A potential frequency offset or a
wrong signal bandwidth can be identified with its help.

A potential frequency offset is not compensated for this measurement, so it should be
checked that it is low.

The limits to check the results against can be set by using the LINES hardkey.
Each signal bandwidth (cf. parameter Channel Bandwidth, page 67) stores its own set
of limits. All limits are automatically set to the ones defined in [2] when a PRESET is
performed. Afterwards the user can change them.

The measurement "ACP Due to Modulation” is useful

• for checking if the requirements defined in [2] and [1] are met.

• for checking if the transmitter disturbs adjacent channels.

• for checking on spurs and interferers by means of the FFT trace.

For this measurement it is of course required that the offset channels are inactive.

The RRC filter is as defined in [2] and [1]:

• Roll-off: 0.35

• Design symbol rate: 18 KHz

• Filter’s frequency offset relative to the TX channel’s nominal center frequency

depends on the set signal bandwidth. For the measurement "ACP due to

And the slot’s “Average Subcarrier Reference Power” is the measured total
“Reference Power” of the whole slot (mean power of ALL sync and pilot symbols,
please refer to Formula 49), divided by the number of subcarriers.
The final result is a vector, one value per subcarrier. It is displayed (trace results)
or condensed to scalar results (result table) by mathematical operations.

• For “Flatness Pilots” this is in detail:
Deviation of the measured power of any pilot symbol in each subcarrier from the
corresponding subcarrier’s “Reference Power” (please refer to Formula 45).
The final result is a kind of matrix with the size: number of subcarriers times
number of symbol positions in the slot. But because not all subcarriers and not all
symbol positions contain a pilot symbol the result matrix is a sparse matrix. It is
condensed to a vector (trace results) or even more to scalar results (result table)
by mathematical operations.

The table in the upper part of the result display shows numeric results (for details
please refer to page 110):

• As first result the Total Reference Power of the whole slot, i.e. the mean power

of all pilot and sync symbols in the whole slot.

• As second result the Average Subcarrier Reference Power, i.e. the first result

divided by the number of carriers.

• As third result the deviation of the Average Subcarrier Reference Power

(second result) from the Reference Powers measured separately for each
subcarrier (mean power of pilot and sync symbols in that subcarrier).
Additionally it shows in which subcarrier the maximum and minimum (unit “dB”)

deviation occurred.

• As fourth result the deviation of the power of any pilot symbol in a subcarrier

from that subcarrier’s measured Reference Power. Additionally it shows in
which subcarrier and at which symbol position the maximum and minimum

unit “dB”) deviation occurred.

(

The lower part of the result display shows the result traces versus subcarrier index.
Note:

• Pilot Symbol Flatness can only be measured and displayed for subcarriers that

contain at least one pilot symbol.

• Subcarrier Reference Power Flatness is measured for all subcarriers.

Activating a marker (please refer to page 94) delivers more information.

• For “Flatness Carrier” measurement:

Maximum, minimum, average and standard deviation (== RMS) results for the
subcarrier the marker resides on.

• For “Flatness Pilot” measurement:

Maximum, minimum, average and “dB”-standard deviation (== linear-scale
RMS) results for all the pilot symbols in the subcarrier the marker resides on.

Note: Both the result table in the upper half and the traces in the lower half distinguish
two kinds of averaged results:

• “AVG”:

For all absolute powers (shown in unit “dBm”): Arithmetic averaging of powers
(unit Watt) is done.
For power deviation results (shown in “dB”): Arithmetic averaging of the
deviations in linear scale is done.
If the power deviations vary around 0 dB, their average will tend towards 0 dB,
they compensate eachother.

• “StdDev”:

For all absolute powers “Total Reference Power (Slot)” and “Average
SubCarrier Reference Power”:
This column displays the straight-forward standard deviation of the powers,
calculated in unit “Watt”.
For the power deviations (unit “dB”):
This column displays the standard deviations of the “dB” values. But they are
calculated internally by averaging the squares of the deviations in linear scale
(RMS averaging). This prevents that deviations in different directions
compensate eachother. After converting them to unit “dB” the results are
always positive. Because of the RMS averaging done internally the
corresponding trace in the lower half is labelled “RMS”, which is shorter than
“StdDev”.

The measurements "Flatness Carrier” and “Flatness Pilot” are useful

• for checking if “Transmitter output power” requirements of [2] and [1] are met

• for checking if there is a remarkable channel amplitude response

• for checking if the transmitter adjusts all subcarrier powers equally.

• for checking if the transmitter adjusts all pilot symbol powers equally.

Signal Characteristics

he Signal Characteristics settings are the general settings concerning the physical attributes of the

T
signal to be measured.

Frequency

Frequency specifies the nominal Center Frequency of the
signal to be measured.
Also note the Auto Step and frequency step fields below the
Frequency field. The frequency step sets the step size for
adjusting the frequency using the Rollkey. When the Auto Step
box is selected the frequency step size is set equal to the
channel bandwidth.
The Frequency parameter is also editable when analog
Baseband input is selected, however the frequency range is
then limited according to the setting of the "IQ Path” parameter
(refer to page 75) as follows:

IQ Path = I Only Range = 0 to 35 MHz
IQ Path = Q Only Range = 0 to 35 MHz
IQ Path = I + j*Q Range = -35 to 35 MHz

I.e. negative frequencies only make sense for complex
valued signals. Real valued signals (fed into the analyzer
using only one cable) only allow positive frequencies.

When measuring with the digital Baseband input, the
frequency parameter is fixed to 0 Hz and cannot be edited.

Level Settings

he level settings are the general settings concerning the level and attenuation of the signal to be

T
measured.

Auto Level

Auto Level is not available in present releases of the R&S
FS-K110 application.

Signal Level (RF)

Signal Level (RF) specifies the expected mean level of the
strongest burst or slot in the RF input signal. The R&S FS­K110 application automatically adds an assumed constant
Crest Factor of 10 dB to the input Signal Level (RF) to get
and set the Reference Level of the instrument. This
Reference Level sets the instrument’s HW (attenuator,
amplifiers).

Therefore setting Signal Level (RF) too low may cause
compression in the instrument. Setting it too high degrades
the SNR.
The top of the y axis of diagram Magnitude Capture Display
represents the instrument’s Reference Level. So it is
recommended to check there that the peak of the trace
comes close to Reference Level, but never above.

Note that the constant assumed Crest Factor of 10 dB is a
compromise. A signal with 8 carriers will have a lower
maximum Crest Factor in the long run than one with 48
carriers . For 48 carriers a (very small) percentage of slots
will even have a crest factor higher than 10 dB. So setting the
Signal Level 1-2 dB higher or lower can gain 1-2 dB of SNR,
depending on the measurement situation.

Also note that the constant assumed Crest Factor of 10 dB
also assumes that there is only one TEDS signal present at
the input. The application captures IQ data with a bandwidth
much larger than the nominal set channel bandwidth, so
some neighbor channels are also "seen” by the instrument
and must be taken into be increasing the parameter Signal
Level (RF).

The Signal Level (RF) parameter is not editable when analog
or digital Baseband input is selected (refer to parameter "IQ
Input” on page 75).

Signal Level (Baseband)

Signal Level (Baseband) has the same meaning as Signal
Level (RF), but for the analog Baseband input (refer to
parameter "IQ Input” on page 75).
The application does not offer this setting if the
corresponding analog Baseband option is not installed!

When using analog Baseband inputs it is even more
important to set the Signal Level not too low. Clipping in the
ADC could occur, which is even worse than rather "soft”
compression in the mixer of the RF input.

Note that the analog Baseband input’s Reference Level is not
continuously adjustable, in contrast to that of the RF input.
Changing the parameter Signal Level (Baseband) has
therefore only a real effect if a threshold for switching the
input attenuator was reached (relais clicks, "Att” reading on
display changes, trace of measurement Magnitude Capture
Display changes).

Full Scale Level

When using the RF or the analog Baseband input the
analyzer uses the parameter Signal Level to adjust its
hardware in a way, that the mixer is not overloaded and no
clipping occurs in the ADC.
But when using the digital Baseband input, the analyzer uses

he parameter Full Scale Level instead. Parameter Signal

t
Level is ignored, because there is no physical signal that has
to be processed and digitized. Instead the digital Baseband
input gets a stream of IQ data that has been digitized (or has
been generated by means of SW) outside the analyzer. The
analyzer can therefore not know the voltage that originally
corresponded to a certain IQ sample magnitude.
The parameter Full Scale Level tells the analyzer which
voltage corresponds to the maximum I or Q value that can be
fed into the digital Baseband input (0x7FFFF as integer or as
fixed point about 1.0 +j*0.0 or 0.0 +j*1.0).

The application does not offer this setting if the digital
Baseband option FSQ-B17 is not installed or the digital
Baseband input is not used as signal path!

Remote: INP:DIQ:RANG

Auto checkbox:
If not checked, the correct Full Scale Level value must be

If checked, the Full Scale Level value cannot be entered
manually. Instead the R&S FS-K110 expects that the device­under-test sends the correct Full Scale Level value via the
LVDS connection. Only certain R&S test transmitters will
support this feature.
It is recommended to not check this checkbox right now.

Ext Att

Remote: INP:DIQ:RANG AUTO OFF

Ext Att specifies the external attenuation or gain applied to
the input signal. A positive value indicates attenuation, a
negative value indicates gain.

Set this value if the signal is attenuated or amplified before it
is fed into the instrument and the application should
nevertheless show correct power results.

All displayed power level results will be shifted by this value.
Exception: The Reference Level and Signal Level ignore the
external attenuation value. It is important to know the actual
power level the instrument’s HW must bear.

When using the digital Baseband input, the Ext Att parameter
is disabled and ignored. The parameter Full Scale Level can
be used to describe the scaling of the signal.

Data Capture Settings

he Data Capture settings specify how much data is to be captured.

T

Capture Time

Capture Time specifies the time (and therefore the amount
of data) to be captured in each capture buffer.
The Capture Time can be specified in TEDS full time-slots
or seconds.

Note that the Magnitude Capture Display shows this time
duration and the slot search algorithm searches slots in it.
Use the Magnitude Capture Display to check if there are at
least some slots present in every sweep.

Increase the Capture Time if no slots are found at all or
slots are not found in any sweep.
Possible reason: The slot search algorithm needs some
extra time before and after a slot to accept it. So for very
short Capture Times it is

• unlikely that a slot is in the buffer

• AND additionally in the middle of the short buffer.

A maximum of 108 full TEDS slots equal to 1.53 seconds
can be specified for the capture time.

When using the digital Baseband input: For a parameter
Digital Input Sampling Rate much higher than needed for
capturing a TEDS signal (larger than 10 MHz, depends on
channel BW) the analyzer might automatically reduce the
maximum Capture Time that can be used.

Remote: SENS:SWE:TIME

Number of Slots to Analyze

Number of Slots to Analyze specifies the number of slots to
be measured. A maximum of 100000 can be specified.

data and measuring until the requested number of slots has
been reached.

Swap IQ

Swap IQ can tell the application to interchange the I an Q
parts of the captured IQ data. This can reverse an IQ swap
that was done in the DUT by intention or by mistake.
If the IQ swap settings in the DUT and the R&S FS-K110 do
not match, no slots will be found and analyzed (except the
carrier frequency error is very small).

The settings for this parameter are:

• OFF: Do not interchange I and Q parts.

• ON: I and Q parts of the IQ data are interchanged.

Please note, that the application will first mix (if necessary)
the input signal (which can be real valued) to the complex
Baseband (signal is now complex valued) and then
interchange I and Q.
As a consequence:

• Feature Swap IQ is only identical to interchanging the I

and Q cable of the analog Baseband input if the center
frequency is exactly zero.

• Feature Swap IQ is even allowed for analog Baseband

operation using only one cable ("low IF” operation).

IQ Path

IQ Path allows the selection of the input path for analog
Baseband inputs.
Either

• a single input (I or Q) may be used (i.e. the signal is real
valued "low IF” signal modulated on a carrier of for example

10 MHz). The other input is internally set to zero.

• or both inputs may be used (complex baseband signal,
I+j*Q).

The IQ Path parameter is editable only when analog Baseband
input is selected by means of parameter "Input”, page 74.

Balanced

Balanced switches the analog Baseband inputs between
symmetrically (balanced) and asymmetrical (unbalanced).

anti-aliasing filter is internally applied to all the IQ inputs.
The filter must be turned on if there might be frequency
components (harmonics) above about 40 MHz.
The amplitude and phase equalized single sided bandwidth of
the analog Baseband inputs is for

• Low pass On: 30 MHz

• Low pass Off: 36 MHz

The Low Pass parameter is editable only and has an effect

Dither

When switched on the Dither parameter specifies that a 2
MHz wide noise signal at 42.67 MHz is injected into the
signal path of the analog Baseband input. It appears in the
spectrum at 38.92 MHz.
The dither signal distinctly improves the linearity of the A/D
converter at very low signal levels (low drive level at the
A/D converter) and thus the accuracy of the level displayed.

The Dither parameter is editable only and has an effect only
when analog Baseband input is selected.

Digital Input Sampling Rate

Specifies which sample rate the IQ signal has which is fed
into the analyzer’s digital Baseband input.
Do not confuse with the transmission speed of the digital
Baseband input, which can be totally different (e.g. if IQ
data was stored in a memory)!

Auto checkbox:
If not checked, the correct Digital Input Sampling Rate
value must be entered manually.
If checked, the Digital Input Sampling Rate value cannot be

ntered manually. Instead the R&S FS-K110 expects that

e
the device-under-test sends the correct Digital Input
Sampling Rate value via the LVDS connection. Only certain
R&S test transmitters support this feature.
It is recommended to only check this checkbox when using
a suitable R&S test transmitter.

Remote: INP:DIQ:SRAT AUTO ON

Setting a too low Digital Input Sampling Rate will cause a
warning, because the IQ signal’s bandwidth might become
too low for running all measurements reliably (especially
ACP measurements). The instrument will continue
measuring, because most measurements do not need such
high sampling rates as the ACP measurements. Of course
results can not be guaranteed in this operation mode.

Channel BW: Minimum sampling rate without warning:
25 KHz 259.2 KHz
50 KHz 259.2 KHz
100 KHz 324.0 KHz
150 KHz 388.8 KHz

Digital Input Sampling Rates much higher than needed for
capturing TEDS signals (greater than 10 MHz, depends on
channel bandwidth) might cause the analyzer to
automatically reduce the maximum capture time that can be
used.

The Digital Input Sampling Rate parameter is editable only
and has an effect only when digital Baseband input is
selected.
The application does not offer this setting if the digital
Baseband option FSQ-B17 is not installed!

ExIQ Box Settings

This button invokes a tool for the configuration of the R&S
ExIQ Box. The R&S ExIQ Box must be connected to the
analyzer’s USB socket (USB cable).

First scenario:
The digital baseband inputs / outputs of R&S signal
generators and R&S signal analyzers can be connected
directly to each other (without an R&S ExIQ Box) because
they use the same digital interface format. The invoked tool
will recognize that no R&S ExIQ Box is present to
configure.

Second scenario:
If the device under test uses a different digital interface
format, the R&S ExIQ Box can serve as a versatile digital
interface adapter between the device under test and the
signal analyzer. The invoked tool allows setting the
parameters of the R&S ExIQ Box.

R&S FSQ-K110 Measurements & Settings

Demodulator Settings

he demodulator settings specify the characteristics of the slots to be considered in the measurement

T
results and how the demodulator should work.

Slot Type

Slot Type specifies the type of slot/burst to analyze. This a
repeat of the Slot Type parameter given in the General
Settings view.
Setting this parameter not correctly will in most cases cause
the slot search algorithm to decline all slots and no slots at all
will be demodulated. For details refer to chapter "Slot search
details” on page 16.

Remote: SENS:DEM:FORM:BAN:BTYP

Payload Modulation

Payload Modulation specifies the type of modulation used for
the data symbols of the slots.
Setting this parameter to the wrong value will not affect the
slot search (i.e. which slots are found and demodulated) but
will make the demodulation worse and cause measuring of
wrong modulation errors.

The choices of modulation are: 4 QAM, 16 QAM, or 64 QAM.

For Random Access Burst only 4 QAM is allowed.

Remote: SENS:DEM:FORM:BAN:MOD

Demod RRC Roll-off

Max Carrier Offset

Demod RRC Roll-off is currently not yet available.
This is the RRC filters’ Roll-off factors the application uses for
demodulation (not ACP!). It is fixed to 0.2.

Max Carrier Offset specifies the maximum carrier frequency
error a input signal is allowed to have, so that all slots
contained in it will still be reliably found (assuming that the
slot type and the number of carriers are set correctly, the pilot
and syncs are according to standard [2] and there are not
excessive noise and distortion).

Specify ±1 kHz if the signal is known to be within +/- 1 kHz of
the nominal carrier frequency. This setting will result in faster
demodulation times and improves the applications
performance in case of strong signals in adjacent channels.

Otherwise (especially if the slot search algorithm fails or the
DUT’s frequency error is known to be large), specify ±10 kHz.

Pilot Tracking specifies whether or not the measurement
engine will try to track the amplitude and phase changes
during the burst by means of the known sync and pilot
symbols and compensate those changes. At a certain symbol
instant the same complex compensation value is applied in
all subcarriers. Please refer to Fig. 44 and its descriptions.

R&S FSQ-K110 Measurements & Settings

Measurement Time Settings

any measurements of the R&S FS-K110 application rely on IQ data that was exactly cut out of the raw

M
IQ data around every found slot. The exact slot timing is known for each slot, because each slot was
demodulated.
The Measurement Time settings specify these periods to cut out for the various measurements, i.e. the
"gating” settings.

Auto

The setting "Auto” is currently not yet available. This means
all times are set to reasonable values or as standard [1] or [2]
specify.

ACP due to Transients

Setting the Measurement time for ACP due to Transients is
currently not yet available. This means the time duration of
the trace is fixed to the slot or subslot duration plus 6 symbol
durations before and after that.

PVT

Spectrum FFT

Setting the Measurement time for PVT is currently not yet
available. This means the time duration of the PVT trace is
fixed to the slot or subslot duration plus 6 symbol durations
before and after that.

Setting the Measurement time for Spectrum FFT is currently
not yet available. This means the gating time for cutting out
the FFT input data is fixed to the slot or subslot duration plus
6 symbol durations before and after that.

Exception: If no slot at all is found in the capture buffer, the
whole capture buffer is processed by the FFT to give a
trouble-shooting help. The statistic of the Spectrum FFT
measurement (average trace) ignores this special kind of
result.
