Simplify Broadcast Radio Signal Creation

The Keysight Technologies, Inc. Signal Studio software is a flexible suite of signalcreation tools that will reduce the time you spend on signal simulation. For broadcast radio standards including FM Stereo/RDS, DAB, DAB+, T-DMB, and XM, 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 advanced 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

Apply your signals in real-world testing

Once you have set up 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.

• Vector signal generators
• X-Series: MXG and EXG
• ESG
• PXIe M9381A
• PXB baseband generator and channel emulator
• SystemVue simulation software

Component and Transmitter Test

Signal Studio’s advanced capabilities enable you to create and customize FM Stereo/ RDS or DAB/DAB+/T-DMB/XM 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, and spectral mask testing
• Set parameters such as FM deviation, pilot deviation, RDS deviation, and RDS information for FM Stereo/RDS signals and transmission mode, service/service component settings, FIG for DAB/DAB+/T-DMB signals, one terrestrial carrier and two satellite carriers in ensemble A and B, respectively for XM signals
• Configure multi-carrier waveforms, each with different settings
• View CCDF, spectrum and time domain graphs to investigate the effects of power ramps, modulation formats, power changes, clipping, and more on device performance
