Contents of the Application Firmware R&S FS-K82 Software Manual
This software manual contains information on the operation of the Spectrum Analyzer
R&S FSU, R&S FSP or Signal Analyzer R&S FSQ configured with the Application
Firmware R&S FS-K82. It includes a description of the menus and the remote-control
commands for the cdma2000/1xEV-DV base station test application firmware.
All other aspects of analyzer operation can be taken from the operating manual of the
analyzer.
The software manual of the application firmware consists of 10 chapters:
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.

2.1 Getting Started
The following chapter explains fundamental cdma2000 base station tests using a
measurement setup with the signal generator R&S SMIQ as the device under test. It
describes how operating and measuring errors can be avoided by means of correct
default settings.
The measurement screen is presented in Chapter 6 for the different measurements.
Attention is drawn to important settings exemplifying how to avoid measurement errors
during measurements. The correct setting is followed by a demonstration of the effect
of an incorrect setting. The following measurements are performed:
As the cdma2000 application firmware also supports the IS95 Standard, the examples
are performed on an IS95 signal..
Measurements are performed with the following units and accessories:
● Spectrum analyzer R&S FSU, R&S FSP or Signal analyzer R&S FSQ with
application firmware R&S FS-K82 base station test for cdma2000.
● Vector signal generator R&S SMIQ with option B11 data generator / B20

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

1. Up to a frequency error of roughly 1.5 kHz a CDP measurement on the analyzer is
still possible. There is no apparent difference in measurement accuracy of the CDP
measurement up to this frequency error.
1. Above a 1.5 kHz frequency offset, the probability of incorrect synchronization
increases. The 'SYNC FAILED' message appears.
2. Above a frequency error of roughly 2 kHz, a CDP measurement cannot be
performed. The 'SYNC FAILED' message appears.
Setting on R&S SMIQ
► Reset the signal generator center frequency to 878.49 MHz:
[FREQ: 878.49 MHz]
The analyzer center frequency should not deviate from the DUT frequency by
more than 1.5 kHz.

R&S FS-K82 Getting Started
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

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.
3.1 Standard-Test setup
Fig. 1 BTS test setup
1. Connect the antenna output (or TX output) of the base station to the RF input of
the analyzer by means of a power attenuator exhibiting suitable attenuation.
The following values for external attenuation are recommended to ensure that the
Software Manual 1007.9797.44 - 06 20
RF input of the analyzer is protected and the sensitivity of the unit is not reduced
too much:

0 dB
2. For signal measurements at the output of two-port networks, connect the reference
frequency of the signal source to the rear reference input of the analyzer (EXT
REF IN/OUT).
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
station to the rear trigger input of the analyzer (EXT TRIG GATE).

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
hot key on page 79)

Fig. 4 Overview of menus
R&S FS-K82 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).
