TECHNICAL OVERVIEW

Simplify Custom Signal Creation
Keysight Signal Studio Pro for custom modulation software is a flexible suite of signalcreation 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 LTE, ZigBee (BPSK and O-QPSK), WiSUN, ITU G.9959, DVB-T/H, ISDB-T, DOCSIS3.1, DVB-S2/S2X, APCO, TERTRA, dPMR, DECT, ARIB, DMR, NXDN, DAB, CDR, DRM and more with convenient quick setups, then easily modify and customize them.
Two types of licenses are available: 1) A PC based license for waveform creation and download to a supported signal generators (N7608APPC), 2) An instrument embedded license only for waveform playback (N7608EMBC).
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.

Signal Studio Pro Licensing
Signal Studio Pro for Custom Modulation supports three types of licenses: PC-based license (N7608APPC), waveform playback license (N7608EMBC) and RAW IQ export license (N7608RAWC).
­ N7608APPC is PC based license which enables you to generate, export and make a live connection to download custom signal waveforms into any signal generator, AWG, PXIe SG, or PXIe VXT without N7608EMBC license. N7608APPC is recommended for R&D teams.
­ N7608EMBC is an embedded license installed on a signal generator, which enables you to generate, make a live connection to download and offline playback Custom Modulation signal waveforms with Keysight signal genera¬tors, VXTs or AWGs. N7608EMBC is recommended for design and verification or manufacturing teams.
­ N7608RAWC is PC based license to enable unencrypted IQ data export capability. N7608RAWC license requires N7608APPC license.
­ N7608APPC is available in the following license types: node-locked, transportable, floating or USB portable, each with perpetual or time-based flexible license terms.
­ N7608EMBC is available in the following license types: node-locked, or transport¬able, each with perpetual or time-based flexible license terms.
­ PC license mode: when N7608APPC license is installed in a stand-alone PC, then the N7608C software is working as the PC license mode. No license is required inside the instrument if downloaded but the downloaded waveform can't be saved or renamed.
­ Instrument license mode: each instrument needs a valid license (N76xxAPPC or N76xxEMBC) to playback waveforms. Waveforms can be saved in signal generators for offline playback.
