Signal Studio for Custom Modulation

N7608B

Technical Overview

  • Create 5G candidate modulation waveforms (FBMC, F-OFDM, GFDM, UFMC) with an easyto-use graphical user interface
  • Create custom OFDM and IQ waveforms for emerging wireless, 5G, and aerospace/defense custom/proprietary applications
  • Customize OFDM and IQ quick setups for applications such as DAB, DVB-T/H, DVB-SH, ISDB-T, SOQPSK, DVB-S2X APSK and more
  • Apply crest factor reduction to reduce peak-to-average ratio
  • Use with Keysight sources for flexible RF/microwave frequency and modulation bandwidth configurations

Simplify Custom Signal Creation

Keysight Signal Studio for custom modulation software is a flexible suite of signal creation tools that will reduce the time you spend on signal simulation. 5G candidate modulations, custom OFDM, and IQ signals can quickly and easily be generated for component, transmitter, and receiver test of emerging standards and 5G applications. Accelerate the definition of popular signals such as DAB, DVB-T/H, WLAN, SOQPSK, and DVB-S2X APSK with convenient quick setups, then easily modify and customize them.

Component and transmitter test

Signal Studio uses 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 test signals include parametric test of components such as amplifiers and filters, and performance characterization and verification of RF sub-systems.

Receiver test

Signal Studio enables you to create signals for receiver uncoded bit-error-rate (BER) for early testing of receiver hardware.

Apply your signals in real-world testing

Once you set up your signals in Signal Studio, you can download them to a variety of Keysight instruments. This offers flexibility in generating signals at various carrier frequencies with different bandwidths for multiple applications. Signal Studio software provides a cost-effective way to tailor your test equipment to your measurement needs in design and development.

Component and Transmitter Test

Signal Studio enables you to create and customize waveforms to characterize the power and modulation performance of your components and transmitters. Easily manipulate a variety of signal parameters to simplify signal creation.

  • Create spectrally-correct signals for channel power, spectral mask, and spurious testing
  • View CCDF and OFDM resource mapping and modulation (5G candidate and custom OFDM), and data and idle segments (custom IQ) to graphically evaluate signal configuration and to investigate the effects on device performance
  • Save 89600 VSA setup files for EVM testing with Keysight signal analyzers and oscilloscopes
