N7623B Signal Studio for Digital Video

Technical Overview

• Create Keysight validated and performance optimized reference waveforms compliant with DVB-T/H, DVB-T2, DVB-C/S/S2, ISDB-T/TB/TSB/TMM, ATSC, ATSC-M/H, DTMB (CTTB), CMMB, J.83 Annex A/B/C, and DOCSIS 1.x/2.0/3.0/3.1 standards
• Perform BER tests with PN sequence, all 1s, all 0s, or user-defined data patterns or subjective evaluation with MPEG2-TS or ColorBar demo file
• Real-time fading, SFN simulation, MISO simulation, AWGN, and interferers for conformance testing with N5106A PXB
• Accelerate the signal creation process with a user interface based on parameterized and graphical signal configuration and tree-style navigation

Simplify Digital Video Signal Creation

Keysight Technologies, Inc. Signal Studio software is a flexible suite of signal-creation tools that will reduce the time you spend on signal simulation. For digital video standards including DVB-T/H, DVB-T2, DVB-C/S/S2, ISDB-T/TB/TSB/TMM, ATSC, ATSC-M/H, DTMB (CTTB), CMMB, J.83 Annex A/B/C, and DOCSIS 1.x/2.0/3.0/3.1, Signal Studio’s performance-optimized reference signals—validated by Keysight—enhance the characterization and verification of your devices. Through its application-specific user-interfaceyou’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 coded, statistically correct signals include:

• Parametric test of components, such as amplifiers, filters, gap-filler and repeater
• Performance characterization and verification of RF sub-systems

Receiver test

Signal Studio’s advanced capabilities enable you to create fully channel-coded signalsfor receiver bit-error-rate (BER), frame error rate (FER), packet-error-rate (PER), or subjective failure point (SFP) analysis.

 Applications include:

• Performance verification and conformance test of receivers, during RF/baseband integration and system verification
• Coding verification of baseband subsystems, including FPGAs, ASICs, and DSPs
• Receiver chipset design and verification, performance test (IC design house or certification lab)
• Receiver module integration and verification (terminal vendors)
• Receiver manufacturing for phones (smart phones) or set top boxes

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 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

Signal Studio’s advanced capabilities enable you to create and customize waveforms compliant with digital video standards, including DVB-T/H/T2/C/S/S2, ISDB-T/TB/ TSB/Tmm, ATSC, ATSC-M/H, DTMB (CTTB), CMMB, J.83 Annex A/B/C and DOCSIS 1.x/2.0/3.0/3.1, 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, spectral mask, and spurious testing
• Set parameters such as channel power and data channel modulation type (BPSK, QPSK, 16QAM, 64QAM) for modulation verification and analysis, such as MER, BER tests
• Configure multi-carrier waveforms, each with different modulation settings, frequency offsets, power, baseband filter, and more
• View CCDF, spectrum and time domain graphs to gain insight into the effects of power ramps, modulation formats, power changes, clipping, and other effects on device performance
