The Adjacent Channel Power and EDR In–band Spurious Emissions measurements
are performed in the "Spectrum Analyzer" mode. For this test case the complete frequency band is scanned using a sequence of zero span measurements.
All other test cases are based on a digital I/Q demodulator which determines the 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 tempera-

ture 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
The Figure 2-1 shows the R&S FSV/FSVA hardware from the IF to the processor. The
analog IF filter is fixed to 20MHz. The A/D converter samples the 20 MHz IF signal with
a sampling frequency of 65.83 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. For EDR–measurements, the oversampling
factor is always fixed to 4. The resulting I/Q data are stored in a memory of 512 k
words for I and Q respectively. The hardware trigger (external or IF power) controls the
memory access.
Figure 2-1: Block diagram of the signal processing architecture of the R&S
2.5 Bandwidths
The Bluetooth RF Specification defines a minimal bandwidth of 3 MHz. The digital
bandwidth 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.

Oversampling
2.6 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 spectrum analyzer supplies an optional
filter with a passband only appropriate for the channel to measure. This filter is used by
default. 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 selected oversampling factor. As a result the displayed deviation
value is increased by 3.2%, but without the filter the displayed deviation value can
increase dramatically due to interference from adjacent channels. Generally the result
is 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.
Figure 2-2: Selection of digital filters
Dashed–dotted curve: Standard filter with 4 points / symbol
Solid curve: Optional measurement filter, independent of the points / symbol setting
2.7 Oversampling
The number of samples per symbol is equivalent to the sampling rate in MHz (due to
the symbol length of 1 µs).

Points per Symbol Sampling rate
According to the RF Test Specification an oversampling factor of 4 is required at minimum. For Basic Rate measurements, this oversampling factor can be selected as
oversampling factor in a range from 2 to 32. For EDR–measurements, the oversampling factor is fixed to 4 which is also the default value.
Although possible, a value greater than 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 2.5,
"Bandwidths", on page 16.
The spectrum analyzer uses a timing offset correction 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 timing offset correction Sampling times after timing offset correction
Advantages of the timing offset correction:
●
No jitter with low sampling rates
●
With one sample per zero, the trespassing point 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.

Determining Average or Max/Min Values
2.8 Determining Average or Max/Min Values
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 sweep count function, thus
adapting the measurement to the individual requirements. In single sweep mode, the
calculation of average or maximum / minimum values is performed over a well–defined
number of sweeps (= sweep count). Continuous sweep mode yields continuous averaging and calculation of maximum / minimum values over the whole measurement
time.
Modulation measurements
They are performed in the "Clear Write" trace mode. In continuous sweep mode, a
"live" display is obtained, which allows e.g. an instant view of changes during alignment of a DUT. In single sweep mode and with the sweep count set to 10, the spectrum analyzer evaluates 10 bursts as required by the RF Test Specification. This
means that a result is obtained after exactly 10 bursts.
Power measurements
They are performed in the "Maxhold" trace mode in relation with the defined measurement time. The measurement time is selected in order to make sure that always one
complete burst is acquired. In this case, several sweeps are combined to one trace
before this result trace is evaluated.
Impact of the sweep count on the measurement results
Trace Mode Continuous Sweep Single Sweep & Sweep Count
Clear Write All measurement results (min., max.,
average) are updated with every sweep.
The corresponding values are calculated
based on the current curve.
AVG, MaxHold,
MinHold
All measurement results (min., max.,
average) are updated with every sweep.
The corresponding values are calculated
based on the current curve.
The trace is the continuous average
value (AVG) or the extreme value (MaxHold, MinHold) since the start of the
measurement.
Starts a measurement with n sweeps (n =
sweep count).
All measurement results (min., max.,
average) are calculated based on these n
sweeps.
Starts a measurement with n sweeps (n =
sweep count).
n defines the number of sweeps that are
taken into account for the trace math
functions (AVG, MaxHold, MinHold). The
n sweeps result in one trace and the
measurement results (Min, Max, Average) are calculated based on this summarized trace.
The functions described above differ from the detector functions of the instrument:
●
Detectors combine the measurement data obtained by oversampling to one measurement point on the screen. The kind of combination (Max Peak, Min Peak,
Average, RMS) can be selected.
19Operating Manual 1176.7610.02 ─ 03
Page 20
R&S® FSV-K8
Introduction to Bluetooth Measurements (K8)
Trigger Concepts
●
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 a measurement point 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 set.
2.9 Trigger Concepts
As the DUT (Device Under Test) uses frequency hopping, a trigger method is necessary for two reasons:
●
A measurement is only possible during the period of time, when there is a TX signal (burst) at the frequency under request.
●
In order to determine the modulation characteristics correctly, a synchronization
with the preamble of the signal must be supplied.
If the "Find Sync" softkey is activated, 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 are used 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 correlation 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 is continued as long as no sync
word is found.
After the position of the sync word has been determined, the position of the p0 bit is
calculated from the average value of all zero trespassing points, as defined in the RF
test specification. Finally the samples are 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
is 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 that marks the channel to be
measured a synchronization is also possible with normal hopping operation.

Position of a Bluetooth burst
The RF Test Specification allows different methods to determine the position of a Bluetooth burst:
●
The burst is defined by the p0 bit and the automatically determined packet length
("Find Sync On").
●
The burst is defined by the two 3dB points ("Find Sync Off "and "Find Burst On").
The search of the 3dB points is defined in the RF Test Specification as the alternative method compared with the p0 bit method.

Figure 3-2: Output power measurement
The peak value is determined from the complete contents of the measurement trace,
whereas the average power is calculated from an area of at least 20% to 80% of the
burst.
During the Output Power measurement the Bluetooth demodulator is active in order to
determine the sync word within the signal, which is used as the trigger basis later. The
Bluetooth demodulator is placed in a signal path without video filter. This is why the
video filter cannot be activated with the Output Power measurement.
The EUT (equipment under test) must not exceed the following limits according to the
RF Test Specification:
●
PAV < 100 mW (20 dBm) EIRP
●
PPK < 200 mW (23 dBm) EIRP
●
If the EUT conforms to power class 1: PAV > 1 mW (0 dBm)
●
If the EUT conforms to power class 2: 0.25 mW (–6 dBm) < PAV < 2.5 mW ( 4 dBm)
●
If the EUT conforms to power class 3: PAV < 1 mW (0 dBm)
A violation of these limits is marked on the screen in red color.

This trigger mode is available with detector board 1307.9554.02 Rev 05.00 or higher. It
is not available for input from the R&S Digital I/Q Interface (option R&S FSV/FSVAB17). If RF Power trigger mode is selected and digital baseband input is activated, the
trigger mode is automatically switched to "Free Run".
In RF Power trigger mode the instrument uses a level detector at the first intermediate
frequency. The detector threshold can be selected in a range between - 50 dBm and
-10 dBm at the input mixer. The resulting trigger level at the RF input lies within the
following range:
(-24dBm + RF Att ) ≤ Triggerlevel ≤ (+5dBm + RF Att), max. 30 dBm, for Preamp =
OFF
(-40dBm + RF Att ) ≤ Triggerlevel ≤ (-11dBm + RF Att), max. 30 dBm, for Preamp =

The available trigger levels depend on the RF attenuation and preamplification. A refer-
ence level offset, if defined, is also considered.
For details on available trigger levels and trigger bandwidths see the data sheet.
The bandwidth at the intermediate frequency depends on the RBW and sweep type:
Sweep mode:
●
RBW > 500 kHz: 40 MHz, nominal
●
RBW ≤ 500 kHz: 6 MHz, nominal

The R&S FSV/FSVA is triggered as soon as the trigger level is exceeded around the
selected frequency (= start frequency in the frequency sweep).
Thus, the measurement of spurious emissions, e.g. for pulsed carriers, is possible
even if the carrier lies outside the selected frequency span.

Trg/Gate Level
Opens an edit dialog box to enter the trigger/gate level.
In the trigger modes "Time" and "Power Sensor", this softkey is not available.
Remote command:
TRIGger<n>[:SEQuence]:LEVel:IFPower on page 127
Trg/Gate Polarity
Sets the polarity of the trigger/gate source.
The sweep starts after a positive or negative edge of the trigger signal. The default set-
ting is "Pos". The setting applies to all trigger modes with the exception of the "Free
Run", "Power Sensor" and "Time" mode.
"Pos"
Level triggering: the sweep is stopped by the logic "0" signal and
restarted by the logical "1" signal after the gate delay time has
elapsed.
"Neg"
Edge triggering: the sweep is continued on a "0" to "1" transition for
the gate length duration after the gate delay time has elapsed.
Remote command:
TRIGger<n>[:SEQuence]:SLOPe on page 127
Trigger Offset
Opens an edit dialog box to enter the time offset between the trigger signal and the
start of the sweep.

offset > 0: Start of the sweep is delayed
offset < 0: Sweep starts earlier (pre-trigger)
Only possible for span = 0 (e.g. I/Q Analyzer mode) and gated trigger
switched off
Maximum allowed range limited by the sweep time:
pretrigger
When using the R&S Digital I/Q Interface (R&S FSV-B17) with I/Q Analyzer mode, the maximum range is limited by the number of pretrigger
samples.

max
In the "External" or "IF Power" trigger mode, a common input signal is used for both
trigger and gate. Therefore, changes to the gate delay will affect the trigger delay (trigger offset) as well.
Remote command:
TRIGger<n>[:SEQuence]:HOLDoff[:TIME] on page 126
Trigger Hysteresis
Defines the value for the trigger hysteresis for "IF power" or "RF Power" trigger sources. The hysteresis in dB is the value the input signal must stay below the power trigger level in order to allow a trigger to start the measurement. The range of the value is
between 3 dB and 50 dB with a step width of 1 dB.
Remote command:
TRIGger<n>[:SEQuence]:IFPower:HYSTeresis on page 126
Trigger Holdoff
Defines the value for the trigger holdoff. The holdoff value in s is the time which must
pass before triggering, in case another trigger event happens.
This softkey is only available if "IFPower", "RF Power" or "BBPower" is the selected
trigger source.
Remote command:
TRIGger<n>[:SEQuence]:IFPower:HOLDoff on page 126

3.10.1 Selecting the Appropriate Filter Type
All resolution bandwidths are realized with digital filters.
The video filters are responsible for smoothing the displayed trace. Using video bandwidths that are small compared to the resolution bandwidth, only the signal average is
displayed and noise peaks and pulsed signals are repressed. If pulsed signals are to
be measured, it is advisable to use a video bandwidth that is large compared to the

This command queries the measured value of a delta marker. The corresponding delta
marker is activated, if necessary. The output is always a relative value referred to
marker 1 or to the reference position (reference fixed active).
To obtain a correct query result, a complete sweep with synchronization to the sweep
end must be performed between the activation of the delta marker and the query of the
y value. This is only possible in single sweep mode.
Depending on the unit defined with CALC:UNIT:POW or on the activated measuring
functions, the query result is output in the units below:
