Signal Studio software is a flexible suite of signal-creation tools that will reduce the time you spend on signal simulation. For broadcast radio standards including FM Stereo/RDS, DAB, DAB+, and T-DMB, 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: – P erformance 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 – First-generation MXG – PXIe M9381A – EXT wireless communication test set – PXB baseband generator and channel emulator – M9252A DigRF host adaptor – SystemVue simulation software 03 | Keysight | N7611B Signal Studio for Broadcast Radio - Technical Overview Component and Transmitter Test Figure 1.
