cdma2000 Base Station Test - Application Firmware R&S FS-K82
When configured with the Application Firmware R&S FS-K82, the analyzer performs
code domain power measurements on forward link signals (base station) on the basis
of the 3GPP2 Standard (Third Generation Partnership Project 2).
The "Recommended Minimum Performance Standard for cdma2000 Spread
Spectrum Base Stations Release C", version C.S0010-C dated May 2002, is taken
as a basis.
This Standard has been approved by the following authority with the specified
designation
●
TIA:
TIA/EIA-97-E (also known as IS-97-E)
When the cdma2000 specification is mentioned in the document, these standards are
meant.
The application firmware supports radio configurations 1 to 5. This means that all radio
configurations with a single carrier (1X) are supported. Accordingly, IS95A/B signals
conforming to radio configurations 1&2 can also be measured with this application
firmware. Channels and modulation types of the 1xEV-DV enhancement are supported
as well. In addition to the measurements called for by the cdma2000 Standard in the
code domain, the application firmware features measurements in the spectral range
such as channel power, adjacent channel power, assigned bandwidth and spectrum
emission mask with predefined settings.

2.4 Measurement 2: Measuring the spectrum emission
mask
The cdma2000 specification calls for a measurement that monitors compliance with a
spectral mask over a range of at least 4.0MHz around the cdma2000 carrier. To
assess the power emissions within the specified range, the signal power is measured
with a 30kHz filter. The resulting trace is compared with a limit line as defined in the
cdma2000 standard. The limit lines are automatically selected as a function of the used
band class.
Test setup
► Connect the RF output of SMIQ to the RF input of the analyzer (coaxial cable with
N connectors).

2.6 Measurement 4: Triggered measurement of relative
code domain power
If the code domain power measurement is performed without external triggering, a
section of the test signal is recorded at an arbitrary point of time and the firmware
attempts to detect the start of a power control group (PCG). To detect this start, all
possibilities of the PN sequence location have to be tested in Free Run mode. This
requires computing time. This computing time can be reduced by using an external
(frame) trigger and entering the correct PN offset. If the search range for the start of
the power control group and the PN offset are known then fewer possibilities have to
be tested. This increases the measurement speed.
Test setup
1. Connect the RF output of SMIQ to the RF input of the analyzer.
2. Connect the reference frequencies (refer to measurement 2).
3. Connect external triggering of the analyzer (EXT TRIG GATE) to the SMIQ trigger
(TRIGOUT1 at PAR DATA).

2.7 Measurement 5: Measuring the composite EVM
Composite EVM is the measurement of the mean squared error of the overall signal
required by the cdma2000 specification.
The instrument generated an ideal reference signal from the demodulated data. The
test signal and the reference signal are then compared with each other. The squared
deviation produces the composite EVM measurement.
Test setup
1. Connect the RF output of SMIQ to the RF input of the analyzer (coaxial cable with
N connectors).
2. Connect the reference input (EXT REF IN/OUT) on the rear panel of the analyzer
to the reference output (REF) on the SMIQ (coaxial cable with BNC connectors)

2.8 Measurement 6: Measuring the peak code domain
error
For the peak code domain error measurement, the instrument generates an ideal
reference signal from the demodulated data. The test signal and the reference signal
are compared with each other; the difference between the two signals is projected to
the class of the base Spreading factor. The peak code domain error measurement is
obtained by summing the symbols of each PCG of the difference signal and searching
for the maximum error code.
Test setup
1. Connect the RF output of SMIQ to the RF input of the analyzer (coaxial cable with
N connectors).
2. Connect the reference input (EXT REF IN/OUT) on the rear panel of the analyzer
to the reference output (REF) on the SMIQ (coaxial cable with BNC connectors).

This chapter describes the default settings of the analyzer for operation as a
cdma2000 base station tester. A condition that has to be met before measurements
can start is that the analyzer is correctly configured and supplied with power, as
described in Chapter 1 of the operating manual for the basic unit. Furthermore, the
Application Firmware R&S FS-K82 must be enabled. Installation and enabling of the
application firmware are described in Chapter 1 of this software manual.

3. To ensure that the error limits specified in the cdma2000 specification for
frequency measurements on base stations are met, the analyzer must be operated
with an external frequency reference. A rubidium frequency standard can be used
as a reference source, for example.
4. If the base station has a trigger output, connect the trigger output of the base

Predefined Channel Tables
4 Predefined Channel Tables
By default, the application firmware works in the Automatic Channel Search mode
(softkey CODE CHAN AUTOSEARCH). However, there is also the option of using
predefined channel tables and taking the code domain analysis as a basis. To do this,
select the channel table and enable the predefined search mode (CODE CHAN
PREDEFINED softkey). In accordance with the cdma2000 specification, different
channel tables have already been defined. These tables are listed below. The standard
does not specify a channel number for the data channels. If you wish to use channels
other than those in the predefined channel tables of the firmware application, you may
copy the original tables and adapt the channels in the copy. (Refer to the CHAN CONF

Configuration of cdma2000 Measurements
6 Configuration of cdma2000 Measurements
The most important measurements of a cdma2000 base station can be selected by
means of the MEAS hot key and the MEAS key. They will be explained below on the
basis of the softkey functions.
The CODE DOM ANALYZER softkey activates the code domain analyzer and takes
you to the submenus for selecting the evaluations. Changing the assignment of the hot
key tier during transition to the application ensures that the most important parameters
of the code domain analyzer can be directly accessed on the hot key tier.
The softkeys POWER, ACLR, SPECTRUM EM MASK, OCCUPIED BANDWIDTH, and
SIGNAL STATISTIC enable base station measurements with predefined settings,
which are performed in SPECTRUM mode of the basic unit. The measurements are
performed with the parameters specified in the cdma2000 specification. The user can
modify the settings at a later stage.
EAS key or MEAS hot keys
The MEAS hot key or the MEAS key opens a submenu for selecting the
measurements:
●

POWER enables the channel power measurement with defined default values in
SPECTRUM mode.
ACLR enables the adjacent channel power measurement with defined default
values in SPECTRUM mode.
MULTI CARRIER ACLR enables the multi carrier adjacent channel power
measurement with defined default values in SPECTRUM mode.
SPECTRUM EM MASK performs a comparison of the signal power in different
carrier offset ranges with the maximum values specified in the cdma2000
specification.
OCCUPIED BANDWIDTH enables measurement of the bandwidth assigned to the
signal.
CODE DOM ANALYZER enables the code domain analyzer and opens another
menu for choosing the evaluation type. All other menus of the analyzer are
adapted to the functions of the code domain analyzer mode. The code domain
analyzer is described in a separate chapter starting on page 59.
SIGNAL STATISTIC evaluates the signal with regard to its statistical characteristics
(distribution function of the signal amplitudes).

emissions measurement defined in the cdma2000 specification.
The analyzer measures the power of the useful channel and of the adjacent channels
on the left and right sides. In the default setting, only two adjacent channels are taken
into account. Measurement results are displayed beneath the measurement screen.
The limits depend on the band class setting (BAND CLASS softkey).
The ACLR limit check can be enabled or disabled by means of the ACLR LIMIT

NO. OF ADJ CHAN
The NO. OF ADJ CHAN softkey enables input of the number ±n of adjacent channels
which are taken into account for the adjacent channel power.
Numbers between 0 and 12 can be entered.
The following measurements are performed depending on the number of channels.
0
Only the channel power is measured.
1
The channel power and the power of the upper and lower adjacent channel are
measured.
2
The channel power, the power of the upper and lower adjacent channel and of the
next upper and lower channel (alternate channel 1) are measured.
3
The channel power, the power of the upper and lower adjacent channel, the next
higher and lower channel (alternate channel 1) and the next but one higher and
lower channel (alternate channel 2) are measured.
With higher numbers the procedure is expanded accordingly.

ADJUST SETTINGS
The ADJUST SETTINGS softkey automatically optimizes the unit settings of the
analyzer for the selected power measurement.
All the analyzer settings relevant to power measurement within a specific frequency
range (channel bandwidth) are then optimized as a function of the channel
configuration (channel bandwidth, channel spacing):
●
●
●
●
Frequency span:
The frequency span must cover at least all the channels that have to be taken into
account.
When the channel power is measured, the span is set as twice the channel
bandwidth.
The span setting depends for adjacent channel power measurement on the channel
spacing and the channel bandwidth of the adjacent channel ADJ, ALT1 or ALT2
farthest away from the transmission channel
Resolution bandwidth
RBW  1/40 of channel bandwidth
Video bandwidth
VBW  3  RBW.

Trace math and trace averaging functions are disabled.
The reference level is not affected by ADJUST SETTINGS. It has to be adjusted
separately by means of ADJUST REF LVL
Adjustment is performed once; if necessary, the unit settings can be modified
afterwards.

If the frequency span is large compared with the analyzed
frequency section (or frequency sections), only a few pixels
on the trace are available for the measurement.
Resolution bandwidth
(RBW)
To ensure an acceptable measurement speed and also the
necessary selectivity (for inhibiting spectral components
outside the channel you want to measure, especially the
adjacent channels), the resolution bandwidth must be
selected so that it is neither too small nor too large. As a
rule of thumb, the resolution bandwidth should to be set to
values between 1% and 4% of the channel bandwidth. A
larger resolution bandwidth can be set if the spectrum within
and around the channel you want to measure has a flat
characteristic.
Video bandwidth (VBW)
For a correct power measurement, the video signal must
not be limited in terms of bandwidth. A restricted band of the
logarithmic video signal would result in averaging and thus
in a too low indication of the power (-2.51 dB for very low
video bandwidths). The video bandwidth should therefore
be at least three times the resolution bandwidth.
The ADJUST SETTINGS softkey sets the video bandwidth
(VBW) as a function of the channel bandwidth as follows:
VBW  3  RBW.
Detector
The ADJUST SETTINGS softkey selects the RMS detector.
The RMS detector is selected because it always indicates
the power correctly irrespective of the characteristics of the
signal you want to measure. In principle, even the sample
detector would be possible. However, it would lead to
unstable results due to the limited number of trace pixels for
calculating the power in the channel. Averaging, which is
frequently performed to stabilize measurement results,
leads to the level indication being too low and should
therefore be avoided. The reduction in the displayed power
depends on the number of averages and the signal
characteristics in the channel you want to measure.
SWEEP TIME
The SWEEP TIME softkey activates the entry of the sweep time. With the RMS
detector, a longer sweep time increases the stability of the measurement results.
The function of the softkey is identical to the softkey SWEEP TIME MANUAL in the
menu BW.

NOISE CORR ON/OFF
If the NOISE CORR ON/OFF softkey is activated, the results will be corrected by the
instrument's inherent noise, which increases the dynamic range. When the function is
switched on, a reference measurement of the instrument's inherent noise is carried out.
The noise power measured is then subtracted from the power in the channel that is
being examined. The inherent noise of the instrument depends on the selected center
frequency, resolution bandwidth and level setting. Therefore, the correction function is
disabled whenever one of these parameters is changed. A disable message is
displayed on the screen. To enable the correction function in conjunction with the
changed setting, press the softkey once more. A new reference measurement is
carried out.
Remote: SENS:POW:NCOR ON
FAST ACLR
The FAST ACLR softkey toggles between measurement by the IBW method (FAST
ACLR OFF) and the time domain method (FAST ACLR ON).
With FAST ACLR ON, the power measurement is performed in the different channels
in the time domain. The analyzer adjusts its center frequency in succession to the
different channel center frequencies and measures the power with the set measuring
time (i.e. sweep time/number of measured channels). In doing so, the RBW filters
suitable for the selected standard and frequency offset are used.
The RMS detector is used for correct power measurement. Consequently, no software
correction factors are necessary.
Measure values are displayed in a table, the power in the useful channel being output
in dBm and the power in the adjacent channels in dBm (ACLR ABS) or dB (ACLR
REL).
Selection of the sweep time (i.e. measuring time) depends on the desired
reproducibility of results. Reproducibility of the results increases with sweep time since
power measurement is then performed over a longer period of time.
As a rule of thumb, it is safe to assume for a reproducibility of 0.5 dB (99% of the
measurements are within 0.5 dB of the true measured value) that approximately 500
uncorrelated measured values are necessary (this applies to white noise). Measured
values are assumed to be uncorrelated when their time interval corresponds to the
reciprocal of the measurement bandwidth (i.e. 1/BW).
For cdma2000 the measurement bandwidth is 10 kHz, i.e. measured values at an
interval of 10 µs are assumed to be uncorrelated. Thus a measurement time (sweep
time) of 50 ms per channel is required for 500 measured values. This is the default
sweep time which the analyzer sets in coupled mode. Approximately 5000 measured
values (i.e. the measurement time has to be extended to 500 ms) are required for a
reproducibility of 0.1 dB (99% of all measurements are within 0.1 dB of the true
measured values).

Since the measurement bandwidth is considerably lower for channel power

CHANNEL BANDWIDTH
The CHANNEL BANDWIDTH softkey enables entry of the channel bandwidth for the
transmission channel.
The useful channel bandwidth is normally determined by the transmission procedure.
The default setting of cdma2000 measures a channel bandwidth of 1.2288 MHz.
When measuring by the IBW method (FAST ACLR OFF), the channel bandwidth is
represented on the screen by two vertical lines to the left and right of the center of the
screen. This means that a visual check can be made to determine whether the whole
power of the signal being measured is within the selected channel bandwidth.
With the time domain method (FAST ACLR ON), the measurement is performed in
zero span, the channel limits are not identified here. The analyzer provides all available
channel filters for selection of the channel bandwidth entry. Any channel bandwidths
deviating from this cannot be set. Should deviating channel bandwidths be necessary,
perform the measurement by the IBW method.

kHz limit is defined between 3.25 MHz and 4 MHz. This limit is increased by 6.8 dB so
that the 30 kHz resolution filter can be used for the measurement. The 30 kHz filter
detects more power than the 6.25 kHz filter (10 log 30 kHz - 10 log 6.25kHz = 6.8 dB).

The limits for band classes 1, 4 and 8 are defined by separate limits. RBW switching is
beneficial in this instance to speed up the measurement. The 1 MHz channel filter is
used for the 1 MHz segments. The frequency range is divided into three subsegments. The user's sweep time is then spread over the segments as follows (k=filter
velocity factor k):
Segment1: -4.00 to -2.25 MHz RBW = 1 MHz k = 850 SWT1 = SWT * 1/10
Segment2: -2.25 to +2.25 MHz RBW = 30 kHz k = 2.5 SWT2 = SWT * 8/10
Segment3: +2.25 to 4.00 MHz
RBW = 1 MHz k = 850 SWT3 = SWT * 1/10
For bigger Spans than 4 MHz the sweep time is adjusted in that way that all three
segments are swept with the same filter velocity factor k
For entering the limit "Stricter of" a check determines whether P - 45 dBc > -9 dBm.
If this is the case, the measured value is compared with P - 45 dBc, in all other cases
with -9 dBm.

LIMIT LINE USER
The LIMIT LINE USER softkey enables the creation of user-defined limit lines. The softkey
opens the menus of the limit-line editor, which may be familiar from the basic unit. The limit
lines created by the user are included in the table for LIMIT LINE MANUAL.
The following limit line settings are recommended for base station tests:
Trace 1, Domain Frequency, X-Scaling relative, Y-Scaling absolute, Spacing linear,
Unit dBm.
Unlike the default limit lines on the unit that conform to the standard specifications
when the analyzer is supplied, the user-specified limit line can be specified for the
whole frequency range (4.0 MHz from the carrier) only either relatively (referred to the
reference level) or absolutely.
The supplied limit lines of AUTO and MANUAL modes can also be selected. The

LIST EVALUATION
The LIST EVALUATION softkey reconfigures the SEM output to a split screen. In the
upper half the trace with the limit line is shown. In the lower half the peak value list is
shown. For every range of the spectrum emission defined by the standard the peak
value is listed. For every peak value the frequency, the absolute power, the relative
power to the channel power and the delta limit to the limit line is shown. As long as the
delta limit is negative, the peak value is below the limit line. A positive delta indicates a
failed value. The results are then colored in red, and a star is indicated at the end of
the row, for indicating the fail on a black and white printout.
If the list evaluation is active, the peak list function is not available. Since version 4.00

For multi carrier spectrum emission mask measurement this value can be extended.
User specific limit lines shall than be defined and used.
Remote: CALC:LIM:ESP:TRAN <numeric value>
PEAK SEARCH
The PEAK SEARCH activates a single evaluation of spectrum emission mask. The
limit mask - reduced by an overall margin - is checked against the trace. The fail
positions are marked by crosses as long as not a next sweep is preformed. It is
recommended to use single sweep. Every value is added to a peak list which can be
opened and saved in ASCII format or read out via an IEC/IEEE command.
The peaks are calculated using the same peak search algorithm like markers do. It is
possible to define the peak excursion value via MKR->NEXT, softkey PEAK
EXCURSION. In addition the worst fail of each fail area without a peak is marked and
added to the peak list.
Remote: CALC:PEAK:IMM
PEAKS PER RANGE
The PEAKS PER RANGE softkey defines how many peaks are searched for within
one range. The ranges are according to the band class setting (SETTINGS -> BAND

●

from -1.98 MHz to -0.75 MHz from the carrier,
the area from -0.75 MHz to +0.75 MHz around the carrier,
from +0.75 to +1.98 MHz from the carrier
from +1.98 MHz to +4.00 MHz from the carrier.
The default value of PEAKS PER RANGE is 25.
Remote: CALC:PEAK:SUBR 1...50
MARGIN
The MARGIN softkey defines an overall margin which is subtracted from the limit line
to make the peak search more stronger. If the values of the trace are above the limit
line minus margin value it will be marked with a cross as shown in the peak list. The
DELTA LIMIT of the list will be positive thus indicating that only the margin and not the
limit itself is reached. A negative sign would indicate the real fail.
The default value of MARGIN is 6 dB.

Adaptation of the reference level ensures that the signal path of the analyzer is not

Since the measurement bandwidth is considerably lower for channel power
measurements than the signal bandwidth, the signal path may be overloaded although
the trace is still well below the reference level. When the measured channel power is

6.6 Code domain measurements on cdma2000/1xEV-DV
signals
The Application Firmware R&S FS-K82 features a code domain analyzer. It can be
used to perform the measurements required in the cdma2000 standards with regard to
the power of the different codes and code channels (concentrated codes). In addition,
the modulation quality (EVM and RHO factor), frequency errors and trigger-to-frame
time, and peak-code domain errors are determined. Constellation evaluations and
bitstream evaluations are also available. Furthermore the timing and phase offsets of
the channels to the pilot can also be calculated (refer to the TIME/PHASE softkey).
The observation period can be set as multiples of the power control group (PCG) using
the CAPTURE LENGTH softkey
Basically, the firmware differentiates between the following result classes for the
evaluations:
●
●
●
●
Results which take the overall signal into account over the whole observation
period (all PCGs)
Results which take the overall signal into account over a power control group
(PCG)
Results which take one channel into account over the whole observation period (all
PCGs)
Results which take one channel into account over a power control group (PCG)
The evaluations of the code domain analyzer are performed on a split screen. The
screen is divided into two halves for this purpose.
The upper half of the screen (screen A) displays evaluations which vary by means of
the codes. The lower screen (screen B) displays all other evaluations.

Depending on the symbol rate of a code channel, it has a different Spreading factor
and a different number of symbols per power control group. The relationship can be

With evaluations on the lower screen which have uses symbols on the x-axis, the
maximum number of symbols varies according to the symbol rate of the selected code
channel. With transmit diversity signals (softkey ANT DIV) the symbols of the signal
are distributed on two antennas. Therefore the symbol number is reduced to the half.
With the help of the SELECT CHANNEL and SELECT PCG softkeys, the user can
select the code channel and the power control group (PCG) for which he wants to have
a result displayed. Let us assume that he has selected code channel 1.64 (Walsh code
number 1 for Spreading factor 64) and PCG 2. On screen A, the code domain power

relative evaluation is active and on screen B the symbol EVM evaluation is active.
Screen A thus displays the code domain power evaluation of PCG 2. In this instance
code channel 1.64 is shown in red. In the lower half of the screen you can see the
symbol EVM evaluation of code channel 1.64 in PCG 2 with 24 corresponding values.
The code domain analyzer can be operated in two modes. In CODE CHAN
AUTOSEARCH mode it performs an automatic search for active channels in the whole
code domain. During the search, the PILOT CHANNEL (PICH) at 0.64, the
SYNCHRONISATION CHANNEL (SYNC) at 32.64, the TRANSMIT DIVERSITY PILOT
CHANNEL (TDPICH) at 16.128 and the first PAGING CHANNEL (PCH) at 1.64 are
detected automatically if they are active. In addition, active data channels, generally
referred to as CHAN, are detected with their radio configuration 1+2 or 3 to 5.
The code domain analyzer can be operated in two modes. In CODE CHAN
AUTOSEARCH mode it performs an automatic search for active channels in the whole

detected automatically if they are active. In addition, active data channels, generally
referred to as CHAN, are detected with their radio configuration 1+2 or 3 to 5.
PACKET DATA CHANNELS (PDCH) from 1xEV-DV are always sent from the base
station with Spreading factor 32. The standard defines for these channel radio
configuration 10. These packet channels can be either QPSK (like the normal data
channels CHAN), 8-PSK or 16-QAM modulated. The modulation types is automatically
detected by the application firmware and in case of 8-PSK/16-QAM the detected
channel is recognized as PDCH with radio configuration 10. The difference between
CHAN and PDCH with QPSK modulation is not unambiguous, therefore the softkey
FORCE 1xEV-DV exists which can force the 1xEV-DV recognition (PDCH/radio
configuration 10).
The structure of the PACKET DATA CONTROL CHANNEL (PDCCH) is similar to a
normal data channel (CHAN) and can not be distinguished in the automatic search
mode. But it is possible to add the PDCCH in the CODE CHAN PREDEFINED mode.
In the another mode, CODE CHAN PREDEFINED, the user is given the opportunity of
determining the active code channels in the signal by means of selectable and editable
tables. The automatic channel search is then replaced by this user input.
The code domain analyzer requires the presence of the PILOT CHANNEL (PICH) or,
in the case of OTD (orthogonal transmit diversity), the TRANSMIT DIVERSITY PILOT
CHANNEL (TDPICH).

With the code domain power evaluation, the total signal is taken into account over
precisely one power control group. The power values of the different codes are
determined and plotted in a diagram. In this diagram, the x-axis is the code number
and the y-axis is a logarithmic level axis. The number of codes on the x-axis, which
corresponds to the base Spreading factor, can be set by means of the
BASE SF 64/128 softkey. The power control group to be evaluated can be set by
means of the SELECT PCG softkey.
The power of the channels is referred to the power of the pilot channel PICH (code
number 0) at the default setting. This power reference has been selected since the
total power can vary, between the PCG, due to the possibility of a power level change
in the different code channels. Unlike this variable total power, the power of the PICH
is identical over all PCGs and hence it can be used as a constant reference for the
display. If the second antenna is measured (refer to softkeys ANT DIV and ANT NO.),
the pilot channel of the second antenna TDPICH is used as the reference. The power
reference can be switched to the total power of the signal with the help of the POWER
REF softkey.
Apart from these relative displays, there is also the option of specifying the absolute
power. It can be enabled by means of the CODE PWR ABS/REL softkey. The unit of yaxis is consequently dBm for absolute evaluation and dB PICH for relative evaluation
with regard to the pilot, dB TDPICH for relative evaluation with regard to the pilot when
measuring the second antenna and dB TOT for relative evaluation with regard to the
total power.
The power values of the active and unassigned codes are shown in different colours.
In addition, codes with alias power can occur. In this instance a code contains power
components originating either from a Spreading factor higher than the base Spreading
factor or the own and/or a different antenna as a result of transmit diversity.
The following colours are defined:
●

A channel in CODE CHAN AUTOSEARCH mode (automatic channel search mode) is
referred to as active when the minimum power entered by the user (refer to the
INACT CHAN THRESHOLD softkey) is exceeded and there is an adequate signal-tonoise ratio. In CODE CHAN PREDEFINED mode, each code channel contained in the
user-defined channel table is identified as active.

The code-domain error power measurement reads out the difference in power between
measured and ideally generated reference signals for each code in dB. Since it is an
error power, active and inactive channels can be assessed jointly at a glance with this
evaluation.
With the code-domain error power evaluation, the total signal is taken into account
over exactly one power control group and the error power in the different codes are
determined and plotted in a diagram. In this diagram, the x-axis is the code number
and the y-axis is a logarithmic level axis, the unit being dB. The number of codes on
the x-axis, which corresponds to the base Spreading factor, can be set by means of
the BASE SF 64/128 softkey. The power control group you want to evaluate can be set
by means of the SELECT PCG softkey.
The power values of the active and unassigned codes are shown in different colours.
In addition, codes with alias power can occur. In this instance a code contains power

COMPOSITE EVM
The COMPOSITE EVM softkey selects the evaluation of the error vector
magnitude (EVM) over the total signal (modulation accuracy).
In the composite EVM measurement, the square root is determined from the error
square between the real and imaginary parts of the test signal and an ideally
generated reference signal (EVM referred to the total signal).
The measurement result consists of a composite EVM measured value for each power
control group (PCG). You can set the number of PCGs by means of the
CAPTURE LENGTH softkey. Subsequently, the COMPOSITE EVM evaluation takes
the whole signal into account over the entire period of observation.
Only the channels detected as being active are used to generate the ideal reference
signal. In the case of a channel which is not detected as being active on account of,
say low power, the difference between the test signal and the reference signal and the
composite EVM is therefore very large (refer to the figure).

PEAK CODE DOMAIN ERR
The PEAK CODE DOMAIN ERR softkey selects the evaluation of the peak code
domain error.
With the peak code domain error measurement, the error is between the test signal
and the ideally generated reference signal is projected to the base Spreading factor.
The unit on the y-axis is dB. The base Spreading factor is selected by means of the
BASE SF 64/128 softkey.
The measurement result consists of the numeric value per PCG for the peak code
domain error. You can set the number of PCGs by means of the CAPTURE LENGTH
softkey. Subsequently, the peak code domain error evaluation takes the whole signal
into account over the entire period of observation.
Only the channels detected as being active are used to generate the ideal reference
signal for the peak code domain error. If an assigned code is not detected as being
active on account of low power, the difference between the test signal and the
reference signal is very large. The R&S FS-K82 therefore shows a peak code domain

POWER VS PCG
The POWER VS PCG softkey enables the POWER versus power control group (PCG)

You can set the number of PCGs by means of the CAPTURE LENGTH softkey.
Subsequently, the POWER VS PCG evaluation takes one code channel into account

Fig. 21 Result summary
The top left part specifies the measurement results which concern the total signal (that is, all
channels) for the power control group selected with the SELECT PCG softkey:
Total Power:
Pilot Power:
RHO:
Composite EVM:
Software Manual 1007.9797.44 - 06
Specifies the total power of the signal.
Specifies the pilot power. If antenna 2 (refer to ANT NO softkey) is
selected, the power of the TDPICH is displayed, in all other cases
that of the PICH.
Specifies RHO, the quality parameter. According to the cdma2000
standards, RHO is the normalized, correlated power between the
measured and the ideally generated reference signal. When RHO is
measured, the cdma2000 standards require that only the pilot channel
be supplied.
The composite EVM value is the difference between the test signal
and the ideal reference signal (refer to the COMPOSITE EVM
softkey).

Pk CDE:
IQ Imbalance:
IQ Offset:
The PEAK CODE DOMAIN ERR measurement specifies a
projection of the difference between the test signal and the ideal
reference signal to the selected base Spreading factor (refer to
softkeys PEAK CODE DOMAIN ERR and SELECT BASE SF). The
base Spreading factor, to which the projection is made, is specified
in addition to the measured value.
IQ imbalance of the signal in %
DC offset of the signal in %
The top right part specifies the measured results which concern the total signal (that is,
all channels) for the entire period of observation (that is, all PCGs):
Carrier Freq Error:
Chip Rate Error:
Trigger to Frame:
Specifies the frequency error referred to the set center frequency of the
analyzer. The absolute frequency error is the sum of the frequency
error of the analyzer and that of the device under test.
Frequency differences between the transmitter and receiver of more
than 1.5 kHz impair synchronization of the CDP measurement. If at all
possible, the transmitter and the receiver should be synchronized
(refer to the Getting Started chapter). The frequency error is available
in the unit hertz on the one hand and in ppm referred to the carrier
frequency on the other.
Specifies the chip rate error (1.2288 Mcps) in ppm. A large chip
rate error results in symbol errors and, consequently, possibly in
the CDP measurement not being able to perform synchronization.
This measurement result is also valid when the analyzer could not
synchronize to the cdma2000 signal.
This measurement result reflects the time offset from the beginning of
the recorded signal section until the start of the first PCG. In the case of
triggered data recording, this corresponds to the timing offset "frame
trigger (+ trigger offset) - start of first PCG". If it was not possible to
synchronize the analyzer to the cdma2000 signal, the value of Trg to
Frame is meaningless. Is the trigger FREE RUN selected, dashes (-.--)
are displayed.
No of Active Chan:
Specifies the number of active channels found in the signal. In this case
the detected data channels as well as the special channels are
regarded as active. The result applies with transmit diversity to the
selected antenna (refer to softkeys ANT DIV and ANT NO.).
The bottom part of RESULT SUMMARY presents the results of measurements on the
selected channel and the selected PCG.

Chan Pow rel. / abs.:
Channel power relative (referred to the pilot or total power
depending on the POWER REF TOT/PICH) softkey and the
absolute channel power.
Symbol EVM Pk / rms:
Peak or mean value of the results of the error vector magnitude
measurement (refer to the SYMBOL EVM softkey). The
measurement provides information on the EVM of the selected
channel for the selected PCG at symbol level.
If the MAX/MIN HOLD or AVERAGE trace statistics are enabled using the TRACE
hardkey, the values are interlinked accordingly from one analysis to the next. The
Active Channels, Symbol Rate and Channel.SF values are not statistically interlinked.
In the case of the values which have an expectation value of 0 (Carr Freq Error, Trg to
Frame, IQ Imbal/Offset, Timing and Phase Offset), the maximum value is formed in
such a way that the maximum is sought among the absolute values and then output
with sign. In this way it is possible to determine the largest deviation including the
direction of the deviation. The minimum value is formed in the same way.

CHANNEL TABLE
The CHANNEL TABLE softkey selects the evaluation for the channel assignment
table.
The channel assignment table may contain up to 128 entries, corresponding to the
highest base Spreading factor of 128. The channel assignment table evaluation takes
the total signal into account over exactly one power control group. The power control
group to be evaluated can be set by means of the SELECT PCG softkey.
The table lists first the special channels including the packet channels from 1xEV-DV
then the data channels (CHAN) included in the signal are shown. The channels are
sorted in descending order by symbol rate and in ascending order within a symbol rate
by channel number. Unassigned codes are thus always at the end of the table.

The following parameters are determined by the CDP measurement for the channels:
Type:
Type of channel
Chan.SF:
Number of the channel spreading code (0 to [Spreading factor -1]) including
the Spreading factor of the channel in Chan.SF notation.
Symb Rate:
Symbol rate with which the channel is transmitted
(9.6 ksps to 307.2 ksps)
RC:
Radio configuration
Status:
Status display. Unassigned codes are identified as inactive channels.
Pwr Abs / Pwr Rel:
Specification of the absolute and relative (referred to the PICH or the
total power of signal) power of the channel.
T Offs:
Timing offset. The time offset between this channel and the pilot
channel can be enabled by means of the TIME/MEAS softkey.
Ph Offs:
Phase offset. The phase offset between this channel and the pilot channel
can be enabled by means of the TIME/MEAS softkey.
A data channel in CODE CHAN AUTOSEARCH mode is defined as active when it
exhibits a minimum power (refer to the INACT CHAN THRESHOLD softkey) and an
adequate signal-to-noise ratio. In CODE CHAN PREDEFINED mode, all code
channels contained in the channel table are marked as active.
If the TIME/PHASE softkey is set to ON, the maximum value of the TIMING and
PHASE OFFSET is displayed together with the associated channel on the right-hand
side above the channel table. Since the TIMING and PHASE values of each active
channel can be either negative or positive, the absolute values are compared and the
maximum is then displayed with the original sign.

SYMBOL CONST
The SYMBOL CONST softkey selects the evaluation of the constellation diagram at
symbol level.
Evaluation of the symbols is performed for the selected channel (SELECT CHANNEL

into account the results of a channel for a power control group.
Evaluation of the constellation diagram is possible for unassigned codes, but the
results are meaningless since unassigned code channels do not contain data.
For orientation, the unit circle is added to the figure.

The BITSTREAM softkey selects the "Bitstream" evaluation . Evaluation of the decided
bits is performed for the selected channel (SELECT CHANNEL softkey) and the
selected PCGs (SELECT PCG softkey). This evaluation thus takes into account the
results of a channel for a power control group.
Depending on the symbol rate of the channel, a minimum of 12 and a maximum of 384
symbols can be contained in a power control group. In case of transmit diversity
(softkey ANT DIV) the values reduce to the half. For QPSK modulated channels, a
symbol always consists of two bits: the I-component is displayed first, followed by the
Q-component. For BPSK modulated channels, a symbol always consists of one bit
(only the I-component is assigned). For 8-PSK and 16-QAM modulated symbols, a
symbol consists of 3 and 4 bits respectively. The order is shown in the following figure:

CAPTURE LENGTH
The CAPTURE LENGTH softkey supports input of the number of power control groups
(PCG) that are to be analyzed. The input value is always in multiples of the PCGs. The
range is from 2 to 50 (since firmware version 2.60/3.50 the maximum is increased to
64) for Analyzer R&S FSU, R&S FSQ and from 2 to 12 for Analyzer R&S FSP. With all
evaluations exhibiting one value per PCG on the x-axis, the maximum value on the xaxis is the set CAPTURE LENGTH -1.

SET COUNT / SET TO ANALYZE
This function offers the possibility for the R&S FSQ to capture up to 2432 PCGs (more
than 3 seconds) with a SINGLE SWEEP and then post process all the data with SET
TO ANALYZE.
If the SET COUNT is set to 1 (default value), the device behaves as before and with
the CAPTURE LENGTH the number of PCG can be set.
For R&S FSQ the SET COUNT can be adjusted in the range of 1…38. Is the SET
COUNT greater than 1 the CAPTURE LENGTH will be implicitly set to 64 PCGs and
become unavailable. The SET COUNT defines then how many SETS of 64 PCGs shall
be captured consecutively into the IQ RAM of the R&S FSQ. With the SET TO
ANALYZE softkey the set for which the results are calculated can be defined. The
range is from 0... (SET COUNT-1).

SELECT CHANNEL
You can use the SELECT CHANNEL softkey to select a channel. All evaluations which
take results for a channel into account, specify the results for the newly selected
channel: POWER VS PCG, POWER VS SYMBOL, RESULT SUMMARY,
BITSTREAM, SYMBOL CONSTELLATION and SYMBOL EVM.
In the evaluations CODE DOMAIN POWER, CODE DOMAIN ERROR POWER and
CHANNEL TABLE (all on screen A), the selected channel is marked in red.
A channel is entered as a decimal. The entered value is always converted to the base
Spreading factor. It is displayed in the input field in the format <Channel>.<Base
Spreading factor>.
Example:
● Let the base Spreading factor be 64. (BASE SF softkey).
● Enter the number 14 by means of the SELECT CHANNEL softkey.
● 4.64 is displayed.
Normally, the code is displayed with reference to the base Spreading factor in the
function field above the diagrams.
If the current channel table contains a concentrated channel to which the selected
channel belongs with reference to the base Spreading factor, this concentrated
channel will be displayed with the associated code number and Spreading factor in the
function field and marked in red in the corresponding evaluations.
Example:
● Enter the same details as in the example shown above.
● Channel 2.4 is now active in the channel table.
● The associated code is 14.64, i.e. 2.4 is displayed in the function field and channel
2.4 is marked in red on screen A. In Hadamard order, all the codes belonging to
channel 2.4 are marked: 2.62, 6.64, 10.64, 14.64, ...., 62.64
If the channel configuration changes for the next measurement, the changed channel
for which the channel <channel>.<base Spreading factor> belongs is displayed in the
function field and indicated in red on screen A.
Example:
● Continuing with the above example, the channel configuration has been changed
and now channel 6.8 is active.
● Channel 6.8 is now displayed in the function field and Marked in red on screen A.
In Hadamard order, the codes 6.64, 14.64, 22.64, ..., 54.64 are marked.
The rotating wheel behavior depends on the evaluation on screen A and is geared to
the graphic display. In the case of CODE DOMAIN POWER and CODE DOMAIN
ERROR POWER, it depends on whether the Hadamard or BitReverse order is active.
(Refer to the ORDER softkey.) The adjacent channel is always selected with the
rotating wheel. With the channel table, the rotating wheel is used to scroll through the
list.
Input over the IEC/IEEE bus generally refers to the base Spreading factor.

CODE CHAN AUTOSEARCH
The CODE CHAN AUTOSEARCH softkey supports measurements of the code domain
power analyzer in Autosearch mode. In this mode, the whole code domain (all
permissible symbol rates and channel numbers) is searched for active channels. A
channel is active when the minimum power entered by the user, referred to the total
power, is exceeded (refer to the INACT CHAN THRESHOLD softkey) and an adequate
signal-to-noise ratio is present.
CODE CHAN AUTOSEARCH mode is the default search mode with which the CDP
analysis starts. It is used primarily to provide the user with an overview of the channels
contained in the signal. If the signal contains channels which are not detected as being
active in Autosearch mode, the CDP analysis can be performed with predefined
channel configurations by changing to CODE CHAN PREDEFINED mode.

active channels in the code domain, but the channels of a channel table defined prior
to a measurement are assumed to be active.
When the softkey is selected, a table containing all the channel tables stored on the
measuring instrument is opened. The CDP analysis is switched to "Predefined Channel
Table" mode. The last table of Autosearch mode is initially taken as a basis for the
measurement. This table is available at the RECENT entry.
Switching to one of the predefined channel tables is done by selecting the
corresponding table entry and operating one of the unit keys or by pressing Enter; the
selected channel table is taken as a basis for the evaluation as from the next
measurement. A tick marks the selected channel table.
R&S FS-K82 comes with the following channel table stored on the measuring
instrument:
●

Fig. 29 Table for editing a channel configuration
As a general rule, each of the channel tables stored on the measuring instrument can
be modified at will. The edited table is not stored automatically on the hard disk of the
measuring instrument but only by selecting the SAVE TABLE softkey. This prevents a
table from being accidentally overwritten (such as one of the channel models).
If a table is edited that is currently the basis for the code domain power analysis, the
edited table is used for the next measurement immediately after being saved. The
effects of the changes in the table are therefore immediately visible. Here again, the
edited table is not saved on the hard disk of the measuring instrument until the SAVE
TABLE softkey has been selected.
If a table that is stored on the hard disk of the measuring instrument but is not currently
enabled is edited, the changes will not be visible until it has been saved (SAVE TABLE
softkey) and then enabled.

If the CHAN NO parameter or the Spreading factor of a channel is changed, a check is
made for code domain conflicts after the input has been confirmed (units key). If a
code domain conflict is detected, the channels causing the conflict are identified by an
asterisk. The user is thus given an opportunity to eliminate the code domain conflicts.
When a table with code domain conflicts is used for a CDP analysis, the results are

SELECT CHANNEL
You can use the SELECT CHANNEL softkey to select a channel. All evaluations which
take results for a channel into account, specify the results for the newly selected
channel: POWER VS PCG, POWER VS SYMBOL, RESULT SUMMARY,
BITSTREAM, SYMBOL CONSTELLATION and SYMBOL EVM.
In the evaluations CODE DOMAIN POWER, CODE DOMAIN ERROR POWER and
CHANNEL TABLE (all on screen A), the selected channel is marked in red.
A channel is entered as a decimal. The entered value is always converted to the base
Spreading factor. It is displayed in the input field in the format <Channel>.<Base
Spreading factor>.
Example:
● Let the base Spreading factor be 64. (BASE SF softkey).
● Enter the number 14 by means of the SELECT CHANNEL softkey.
● 14.64 is displayed.
Normally, the code is displayed with reference to the base Spreading factor in the
function field above the diagrams.
If the current channel table contains a concentrated channel to which the selected
channel belongs with reference to the base Spreading factor, this concentrated
channel will be displayed with the associated code number and Spreading factor in the
function field and marked in red in the corresponding evaluations.
Example:
● Enter the same details as in the example shown above.
● Channel 2.4 is now active in the channel table.
The associated code is 14.64, i.e. 2.4 is displayed in the function field and channel
2.4 is marked in red on screen A. In Hadamard order, all the codes belonging to
channel 2.4 are marked: 2.62, 6.64, 10.64, 14.64, ...., 62.64.

If the channel configuration changes for the next measurement, the changed channel
for which the channel <channel>.<base Spreading factor> belongs is displayed in the
function field and indicated in red on screen A.
Example:
● Continuing with the above example, the channel configuration has been changed
and now channel 6.8 is active. Channel 6.8 is now displayed in the function field
and Marked in red on screen A. In Hadamard order, the codes 6.64, 14.64, 22.64,
..., 54.64 are marked.
The rotating wheel behavior depends on the evaluation on screen A and is geared to
the graphic display. In the case of CODE DOMAIN POWER and CODE DOMAIN
ERROR POWER, it depends on whether the Hadamard or BitReverse order is active.
(Refer to the ORDER softkey.) The adjacent channel is always selected with the

account, specify the results for the newly selected PCG: (CODE DOMAIN POWER,
CODE DOMAIN ERROR POWER, CHANNEL TABLE, POWER vs SYMBOL,
COMPOSITE CONSTELLATION, RESULT SUMMARY, BITSTREAM, SYMBOL

FORCE 1xEV-DV
The FORCE 1xEV-DV softkey is necessary in the automatic search mode to support

is not possible to distinguish whether it is a data channel (CHAN with radio
configuration 3-5) or a PACKET DATA CHANNEL (PDCH with radio configuration 10).
This decision is made for the PDCH of the 1xEV-DV system if the softkey is active. If
the softkey is not active (default) the CHAN is detected.

MULTI CARRIER
The softkey MULTI CARRIER activates an additional mode in the signal processing to
improve the processing of multi carrier signals. This allows the measurement on one
carrier out of a multi carrier signal with 1.23 MHz carrier spacing even with identical PN
offset values on all carriers.
This multi carrier mode has by default two features switched on:

●
improved algorithm for signal detection on multi carrier signals
additional low pass filter
For that reason the softkey ENHANCED ALGORITHM and MC FILTER are switched
on if the MULTI CARRIER is activated. The filter type LOWPA (for low pass filter) is
selected.
From this base setting the enhanced multi carrier algorithm can be switched on or off
with the ENHANCED ALGORITHM softkey.
With respect to the MC FILTER there are also different configurations possible:
The MC FILTER ON/OFF softkey allows to switch the additional filter on or off.
If the ENHANCED ALGORITHM and the MC FILTER are switched off the multi carrier
mode is deactivated and the MULTI CARRIER softkey becomes grey. To restart the
multi carrier mode it is necessary to repress the MULTI CARRIER softkey.
The softkey FILT TYPE LOWPA/RRC allows the selection between the automatically
activated low pass filter and a configurable RRC filter with integrated hamming window.
If the RRC filter is selected further two softkeys become available. These are the
softkeys ROLL OFF and CUT OFF FREQUENCY. The first defines the roll off factor,
meaning the type of decay of the filter curve, between 0.01 and 0.30 in 0.01 steps default value is 0.02. The second softkey defines the cut off frequency. This is the
frequency where the cut off of the filter begins - here the default value is 1.25 MHz and
the value is adjustable between 0.1 and 2.4 MHz in Hz-steps.
If the MULTI CARRIER softkey is switched off also the further settings became
unavailable.
Please be aware that the low pass filter is influencing the measured signal quality (like
RHO or EVM) in comparison without an additional filter and the improved algorithm will
slightly increase the calculation time.

INACT CHAN THRESHOLD
The INACT CHAN THRESHOLD softkey supports input of the minimum power which a
single channel must have compared with the total signal in order to be regarded as the
active channel.
Channels below the specified threshold are regarded as "inactive".
The two measurements COMPOSITE EVM and PEAK CODE DOMAIN ERR, which
are specified as measurements on the total signal, are performed using the list of
active channels. Distortions of these two measurements always occur when active
channels are not detected as being active and unassigned codes are wrongly given the
status of "occupied channel". INACT CHAN TRHESHOLD can therefore be used to
influence the results of the two measurements.
Software Manual 1007.9797.44 - 06
89
R&S FS-K82
Configuration of cdma2000 Measurements
The default value is -60 dB, which results in location of all channels by the CDP
analysis with signals such as the cdma2000 test models. If not all channels contained
in the signal are detected automatically, INACT CHAN THRESHOLD must be
decreased.
Remote: SENS:CDP:ICTR -100 dB ... 0 dB
PILOT PWR ABS/REL
The PILOT PWR ABS/REL softkey sets the pilot channel power is displayed in
absolute or relative terms in the result summary. In relative mode, the reference power
is the total power.
Remote: SENS:CDP:PPR ABS | REL
CODE PWR ABS/REL
The CODE PWR ABS/REL softkey selects for the CODE DOMAIN POWER evaluation
whether the y-values should be displayed as absolute (dBm) or relative (dB). With
Relative mode, the reference is either the total power or the pilot power. With ANT OFF
and ANT NO 1, the PICH is the reference of the pilot power; with ANT NO 2 it is the
TDPICH.
Remote:
CALC1:FEED "XPOW:CDP:RAT" (relative)
CALC1:FEED "XPOW:CDP" (absolute)
POWER REF TOT/PICH
The POWER REF TOT/PICH softkey determines the reference power for the relative
power evaluations:
TOT
All relative power values (CDP RELATIVE and POWER VS PCG evaluations)
are referred per PCG to the total power of the signal in the PCG concerned.
PICH
The reference power is that of the PICH, or in the case of ANT NO. 2, that of
the TDPICH in the corresponding PCG.
The default setting of the softkey is PICH.
Since PCG-oriented power control is planned for each channel according to
cdma2000, the total power of the signal will vary from PCG to PCG in accordance with
the power controls of the different channels. With enabled power control and reference
to the total power of the signal, a relative CDP evaluation by means of the PCG
number (POWER VS PCG) does therefore not necessarily reflect the power control of
the selected channel.
Example (theoretical): If there is just one data channel in the signal and its power is
controlled, and if the power is referred to the total power of the signal (which consists
only of the contribution from this one data channel), a straight line will appear in the
POWER VS PCG diagram instead of the expected power staircase. The reference
value TOT of the relative evaluations is therefore only meaningful if the signal does not
contain power control.
Software Manual 1007.9797.44 - 06
90
R&S FS-K82
Configuration of cdma2000 Measurements
The PICH setting, by contrast, reflects the precise variation of power for each PCG in a
selected channel even for signals with power control. Since the PICH is not subject to
power control under any circumstances, the same reference value is used in every
PCG.
ORDER HADAM/BITRE
The ORDER HADAM/BITRE softkey makes it possible to define the channel sort for
the CODE DOMAIN POWER and CODE DOMAIN ERROR POWER evaluations. With
Hadamard order (softkey at HADAM), the codes are sorted in ascending order. With
BitReverse order (softkey at BITRE), channels with concentrated codes are next to one
another, since the code numbers are sorted in bit-reversed order. (Refer to the CODE
DOMAIN POWER and CODE DOMAIN ERROR POWER evaluations.)
Remote: SENS:CDP:ORD HAD | BITR
TIME/PHASE ON/OFF
The TIME/PHASE ON/OFF softkey supports the enabling and disabling of the timing
and phase offset evaluation of the channels to the pilot. If the value of the softkey is
OFF (default setting) or more than 50 active channels are in the signal, dashes ('---')
are entered in the channel occupation table and in the result summary evaluation for
the timing and phase offsets. If the softkey is ON, the evaluation will take place and the
values will be displayed.
Remote: SENS:CDP:TPM ON | OFF
ANT DIV ON / OFF
The ANT DIV (Antenna Diversity) softkey supports enabling and disabling of
orthogonal transmit diversity (two-antenna system). The default setting of the softkey is
OFF. If the value is at ON, the firmware application measures transmit diversity
signals. The ANT NO softkey becomes available.
ANT NO. 1 / 2
The ANT NO. softkey is used to select the antenna for which the evaluation is required
to be performed. With transmit diversity, the signal of antenna 1 or the signal of
antenna 2 or the aggregate signal from both antennas is fed in. The softkey is merely
used to select the antenna for which results will be displayed.
On antenna 1, the pilot channel PICH with channel number 0 and Spreading factor 64
(0.64) is required.
On antenna 2, the transmit diversity pilot channel TDPICH with channel number 16 and
Spreading factor 128 (16.128) is required.
For a correct entry of the predefined channel table with transmit diversity, refer to the

Code class of the channel. With Hadamard order, normally the code
class corresponding to the base Spreading factor. With BitReverse
order, values between 2 and 7
Code number of the channel, values between 0 and 127
- For CODE DOMAIN POWER ABSOLUTE in dBm
- For CODE DOMAIN POWER RELATIVE in dB (referred to the total
or pilot power, refer to the command CDPower:PREFerence)
In Hadamard order, power values of the different codes are normally
specified, in BitReverse order the consolidated channel power is
returned.
0 - inactive channel
1 - power of own antenna
2 - alias power of own antenna
3 - alias power of other antenna
4 - alias power of own and other antenna.
Alias power can be avoided by analysis when the base Spreading
factor is selected correctly. (Refer to the command
CDPower:SFACtor)
Thus four values are transferred for all channels:
<Code class>, <Code number>, <Signal level>, <Power ID>, ...
For sorting the channels and consolidation, Hadamard order or BitReverse order
(refer to the CDPower:ORDer command) is important.
With Hadamard, the different codes are output in ascending order with their code
power. The number of output codes corresponds to the base Spreading factor.
With BitReverse, codes belonging to a channel are next to each other and are
therefore output in the class of the channel with output of the consolidated channel
power. The maximum number of output codes or channels cannot be higher than
the base Spreading factor, but decreases with every concentrated channel.
LIST READ OUT RESULTS OF PEAK LIST EVALUATION
This command reads the peak list of the spectrum emission mask measurement
list evaluation (refer to CALC:PEAK:AUTO ON | OFF). An array of values is
returned for each range of the limit line. The arrays for each limit line range are
following sequentially.
<value array of range 1>, <value array of range 2>, ….., <value array of range n>
The array of each range contains the following value list:

CODE DOMAIN ERROR POWER (TRACE1):
The following is output for each channel:

Code class of the channel normally corresponding to the class for
the CDEP that belongs to the base Spreading factor.
Code number of the channel, values between 0 and 127

orders
0 - inactive channel
1 - power of own antenna
2 - alias power of own antenna
3 - alias power of other antenna
4 - alias power of own and other antenna
Alias power can be avoided by analysis when the base
Spreading factor is selected correctly. Refer to the command
CDPower:SFACtor)
Thus four values are transferred for all channels:
<Code class>, <code number>, <signal level>, <power ID>, ...
For sorting the channels, the Hadamard order or BitReverse order (refer to the
CDPower:ORDer command) is important.
In Hadamard order, the different codes are sorted in ascending order before being
output.
With BitReverse order, codes belonging to any one channel are next to each other.
Because an error power is output with the code domain error power, a
consolidation of the power values is not sensible.
The number of output codes therefore generally corresponds to the base
Spreading factor.

Documentation Overview
The class specifies the Spreading factor:
Class 7 corresponds to the highest Spreading factor (128, symbol rate 9.6 ksps),
and class 2 to the lowest allowed Spreading factor (4, symbol rate 307.2 ksps).
Thus eight values are transferred for all channels:
<Channel type>, <Code class>, <Code number>, <Radio configuration>,
<Absolute level>, <Relative level>, <Timing offset>, <Phase offset>, ...
All detected special channels are sorted first, followed by the data channels, in
ascending order by code class and within the code class in ascending order by
code number. The unassigned codes appear at the bottom of the list with the code
class of the base Spreading factor.

Switch off the analyzer before removing or inserting modules.
Check the setting of the system voltage selector (230 V) before switching on the
unit.
Measure the parameters after a warm–up time of at least 30 min. and the
completion of system error correction of the analyzer and the SMIQ. Only then is it
ensured that the specifications are complied with.
Unless specified to the contrary, all settings are performed on the basis of the
PRESET.
The following conventions apply to settings on the analyzer during the
measurement:
[<TASTE>]
Press a key on the front panel, for example [SPAN]
[<SOFTKEY>]
Press a softkey, for example [MARKER –> PEAK]
[<nn unit>]
Enter a value and terminate your input with the unit, for example
[12 kHz]
{<nn>}
Enter values specified in one of the following tables.
Successive entries are separated by [:], for example [SPAN: 15 kHz]
The values stated in the sections that follow are not guaranteed; only the data
sheet specifications are binding.
