N7600B Signal Studio for W-CDMA/HSPA+

Technical Overviews

Create Keysight Technologies, Inc. validated and performance optimized reference signals compliant to W-CDMA, HSPA and HSPA+ 3GPP Release 11

Perform UE and BTS component testing with a broad collection of predefined 3GPP physical layer DL test models and UL sub-tests

Use predefined reference measurement channels (RMC) and fixed reference channels (FRC) to perform UE and BTS receiver conformance testing

Enable conformance testing with closed-loop HARQ feedback and verification of compressed mode, CELL_FACH, PRACH, and more in UL real-time mode

Create DL DC+MIMO signals for UE receiver test and UL HS-DPCCH with 4C+MIMO feedback for BTS receiver test

Accelerate the signal creation process with a user interface based on parameterized and graphical signal configuration and tree-style navigation

Keysight Signal Studio software is a flexible suite of signal-creation tools that will reduce the time you spend on signal simulation. For W-CDMA, HSPA and HSPA+, 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), or block-error-rate (BLER) 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 and software platforms. 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.

Component and Transmitter Test

Basic N7600B Signal Studio functionality enables you to characterize device perfor­mance under a wide variety of test conditions. Create physical layer W-CDMA/HSPA and HSPA+ signals, so you can work on BTS and UE components to investigate the power and modulation qualities of your device under test. You can also simplify and accelerate testing of standards-based test scenarios with included downlink test models and refer­ence measurement channels, the physical layer definitions of H-Sets 1-11, and uplink Release 6–8 subtests.

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, 4PAM, 16QAM, 64QAM), including HS-DPDCH, S-CCPCH, and E-DPDCH channels, for modulation verification and analysis such as code-domain or EVM testing

Generate multicarrier signals for up to 128 carriers, each with adjustable timing, phase offsets, and clipping, as well as scramble code, TFCI field, and transmitter diversity

Automatically calculate cubic metric and set k-value

View CCDF graphs for insight into the waveform power statistics as system param­eters such as modulation, power, OVSF codes and clipping are varied

Generate slot-length based waveforms to help make fast PA tests with a waveform sequence
