Simplify LTE and LTE-Advanced Signal Creation
Keysight Technologies, Inc. Signal Studio software is a flexible suite of signal-creation
tools that will reduce the time you spend on signal simulation. For LTE and LTEAdvanced, Signal Studio’s performance-optimized reference signals — validated by
Keysight — enhance the characterization and verification of your devices. Through its
application-specific user-interface you’ll create standards-based and custom test signals for component, transmitter, and receiver test.
Component and transmitter test
Signal Studio’s basic capabilities use waveform playback mode to create and customize
waveform files needed to test components and transmitters. Its user-friendly interface
lets you configure signal parameters, calculate the resulting waveforms and download
files for playback. The applications for these partially-coded, statistically correct signals
include:
–– Parametric test of components, such as amplifiers and filters
–– Performance characterization and verification of RF sub-systems
Receiver test
Signal Studio’s advanced capabilities enable you to create fully channel-coded
signals for receiver bit-error-rate (BER), block-error-rate (BLER), packet-error-rate (PER),
or frame error rate (FER) analysis. Applications include:
–– Performance verification and functional test of receivers, during RF/baseband integration and system verification
–– Coding verification of baseband subsystems, including FPGAs, ASICs, and DSPs
More advanced capabilities operate in real-time mode, which is used to define the parameters of nonrepeating and dynamically changing signals needed for receiver testing.
Its graphical interface provides a direct instrument connection for parameter transfer
and closed-loop or interactive control during signal generation.
Apply your signals in real-world testing
Once you have setup your signals in Signal Studio, you can download them to
a variety of Keysight instruments. Signal Studio software complements these
platforms by providing a cost-effective way to tailor them to your test needs in design,
development and production test.

signal generator and an X-Series signal analyzer
Signal Studio’s basic capabilities enable you to create and customize LTE and LTE-Advanced waveforms to characterize the power and modulation performance of your components and transmitters. Easy manipulation of a variety of signal parameters, including
transmission bandwidth, cyclic prefix, and modulation type, simplifies signal creation.
–– Create spectrally-correct signals for ACLR, channel power, spectral mask,
and spurious testing
–– Set parameters such as channel power and data channel modulation type (BPSK,
QPSK, 16QAM, 64QAM, 256QAM) for modulation verification and analysis, such as
EVM tests
–– Use pre-defined E-UTRA test models (E-TM) for downlink, reference
measurement channels (RMC) for uplink
–– Configure multi-carrier waveforms to simulate multi-user, multi-cell signals
–– View CCDF, spectrum, time domain, and power envelope graphs to investigate the
effects of power ramps, modulation formats, power changes, clipping, and other effects on device performance
–– Generate slot length-based waveforms to help make a fast PA tests with a waveform
sequence
–– Dynamic TDD (eIMTA) for uplink and downlink
–– TDD-FDD carrier aggregation for downlink
–– VoLTE: TTI bundling with enhanced HARQ (ARB) for uplink
–– Multi-UE simulation update (Excel import/export) for uplink
Multi-Standard Radio
(MSR) Testing
Today’s modern base stations support multiple radio access technologies. The 3GPP TS37.141 Rel-9
specification defines how to test
these multi-standard base station
transmitters and receivers.
To address the challenges of testing
multi-standard components and
receivers, Signal Studio for LTE and
LTE-Advanced FDD/TDD enables
you to import W-CDMA/HSPA,
GSM/ EDGE, cdma2000/1xEV-DO,
TD-SCDMA, LTE TDD/FDD, and
WLAN waveforms from other Signal
Studio products.
The new waveform library manager,
which requires Option JFP, can help
you manage imported waveforms.
Multiple sample rate waveforms can
be stored to help shorten the time
it takes to combine multi-carrier
waveforms with different sample
rates.

Signal Studio’s advanced capabilities address applications in LTE receiver test, including
the verification of baseband designs and the integration of the baseband and RF modules.
Using waveform playback mode with the capability to generate up to 1024 frames enables
transport-channel coding to validate eNB and UE receiver characteristics and performance.
The real-time mode enables you to define the parameters of nonrepeating signals and provides a direct instrument connection to dynamically change signal
parameters and respond to closed-loop feedback.
eNB receiver testing
–– Choose from a variety of pre-defined fixed reference channel (FRC) configurations
–– Create PUSCH sounding reference signals (SRS), including frequency hopping and UL
control information (UCI) multiplexing
–– Use the PUCCH wizard to create multi-user configurations
–– Customize RV index sequence for HARQ retransmission
–– Dynamically configure uplink 2x2 MIMO signals based on HARQ and Timing
Advanced feedback with real-time signal generation

–– Virtual cell ID enables CoMP environment for eNB and Small Cell test
Conformance test made
easy with N7649B Test
Case Manager
Test Case Manager (TCM) provides
a simplified user interface for quick
and easy set-up of standard-compliant conformance test configurations for eNB receiver tests. With
TCM, simply choose one of the test
cases from TS36.141 clause 7 and
clause 8 from the tree menu and
specify a few parameters such as
eNB type, carrier frequency, etc.
TCM then automatically generates
standard-compliant wanted and
interference waveforms and sets up
the signal generators according to
the standard requirement.

Multi-UE Simulation for eNB receiver capacity testing
Base station R&D engineers request to allow simulating large number of UE to test LTE
eNB capacity. Usually the requirement is to test with hundreds of UE which shares same
frequency bandwidth. The eNB under capacity test shall be able to distinguish different UE
and recognize their RNTI and other physical layer characteristics. Traditional eNB capacity test solution is to use hundreds of real UE, or a UE simulator to generate multiple UE’s
environment.
Signal Studio’s Multi-UE Simulation option adds “ARB based multi-UE simulation” capability which allows for a single waveform generation to simulate up to 100 UEs with each UE’s
modulation type, RNTI, resource block allocation etc. Download only one waveform into one
X-Series signal generator, you can get multiple UE’s simulation without using expensive and
complicated UE simulator solution. An easy-to-use Multi-UE Wizard is provided for quick
access to 100 UE’s configuration.
UE receiver testing
–– Choose a pre-defined fixed reference channel (FRC) configuration for early verification of baseband
–– Create downlink control information (DCI) coding, automatically, based on PDSCH
allocation, UE scheduling and random access, and UL power control
–– Define your own system information block (SIB) and automatically configure master
information block (MIB)
–– Select transmission modes 1 through 10, including transmitter diversity and
spatial multiplexing, with up to 8x8 MIMO configuration
–– Generate Inter-band carrier aggregation signals with cross-carrier scheduling applied, in conjunction with up to 8x8 MIMO in each inter-band
–– Perform HARQ testing with up to 15 simulated retransmission and user-definable RV
index sequence
–– Test E-MBMS with MCH/PMCH and MBSFN RS
–– Simulate HetNet environment simulation with ABS for testing femto cells and also
UE
