DTMB (CTTB) X-Series Measurement App, Traditional UI N6156EM0D

Technical Overview

– Measure DTMB (CTTB) transmitters, exciters, modulators, gap-fillers, tuners, or amplifiers performance

– Perform one-button tests with pass/fail limit per DTMB (CTTB) standards

– Use hardkey/softkey manual user interface or SCPI remote user interface

– Leverage built-in, context-sensitive help

– Flexible licensing provides the option of using perpetual or time based licenses with one or multiple signal analyzers

DTMB (CTTB) Measurement Application

The Keysight Technologies, Inc. DTMB (CTTB) measurement application provides one-button standard-based power and modulation analysis capabilities to help your design, evaluation, and manufacturing of DTMB (CTTB) modulators, transmitters, amplifiers, tuners, and gap-fillers/repeaters. Furthermore, with the optional analog baseband IQ inputs in the PXA or MXA signal analyzer, it can provide you the flexibility of measuring the signal quality and modulation accuracy with RF input or analog IQ input.

X-Series measurement applications can help you:

– Gain more insight into device performance with intuitive display and graphs for your application. Select from our library of over 25 different measurement applications.

– Ensure that your design meets the latest standard. Updates are made to the X-Series measurement applications as standards evolve.

– Apply the same measurement science across multiple hardware platforms for consistent measurement results over your design cycle from R&D to production.

– Choose the license structure that meets your business needs. We provide a range of license types (node-locked, transportable, floating or USB portable) and license terms (perpetual or time-based).

Technology Overview

Digital terrestrial/television multimedia broadcasting (DTMB), also known as China terrestrial television broadcasting (CTTB), is the Chinese national terrestrial digital TV broadcasting standard which was announced on August 18, 2006 and implemented from August 1, 2007. DTMB supports both multi-carrier (C=3780) and single-carrier (C=1) modulation scheme. Both schemes use low density parity check (LDPC) coding in forward error correction (FEC), which can provide superior error correction capability for a better sensitivity especially at higher code rate. Time domain synchronized orthogonal frequency division multiplexing (TDS-OFDM ) is implemented to deliver fast system synchronization and precise channel estimation. The DTMB (CTTB) measurement application gives more convenience to your DTMB (CTTB) system development and manufacturing, including both multi-carrier and single-carrier schemes with one button measurements including standard presets and remote SCPI programming capabilities on X-Series signal analyzers.
