N7623B Signal Studio for Digital Video or DVB

Cost-effective waveform creation for multiple digital video formats including DVB-T, DVB-H, DVB-T2

N7623B Signal Studio for digital video enables you to easily create Keysight validated and performance optimized DVB-T, DVB-H, DVB-T2, DVB-C/S/S2, DTMB (STTB), CMMB, J.83 Annex A/B/C, DOCSIS DS, ATSC and ATSC-M/H waveforms. From a simple graphical user interface specify channel coding, modulation parameters, and OFDM frame structure. The software has the right performance and functionality for manufacturing, including the ability to configure PN, all ones, all zeros, user-defined pattern payload or seamless continuous transport stream (MPEG2-TS) video files for component and receiver test.

High-performance real-time signal creation

N7623B supports creation of real-time DVB-T, DVB-H, DVB-T2, DVB-C/J.83 Annex A/C, DVB-S/S2 and ISDB-T signals. Payload can be a PN9/15/23 or MPEG2-TS file which will be dlwnloaded and saved in the instrument hard drive for future usage. Modulation related parameters can be changed and effective immediately. The real-time video solution is a good choice for DVB-T receiver test, DVB-T2 receiver test, DVB-T2 MISO, SFN simulation, or other performance tests.

Use N7623B with Keysight vector signal generators, which cover a breadth of communications formats, making it ideal for those integrating video, wireless connectivity and mobile communications in a single receiver.
