Key Features & Specifications

Signal analysis

  • Supports DTMB (CTTB) standard of both multi-carrier (C=3780) and single-carrier (C=1) modes
  • Transmitter RF measurement
  • One-button measurements with pass/fail per the standard
  • Runs inside CXA signal analyzer


  • Power measurement: channel power, shoulder attenuation, ACP, CCDF, SEM
  • Modulation accuracy measurement: constellation, MER/EVM (MER RMS/peak, MER by subcarriers, MER by data, system information, and header), frequency error, amplitude error, phase error, quadrature error, amplitude imbalance
  • Channel frequency response, channel impulse response and spectral flatness
  • Manual settings of DTMB (CTTB) signal; provides advanced settings like equalization switch, demodulation frames, PN phase change, SI reference, out-of-band filtering, and clock rate


  • Power accuracy: up to ±0.61 dB (95th percentile)
  • Shoulder attenuation dynamic range: up to 84.5 dB (91.7 dB typical)
  • MER floor: up to 42 dB (C = 3780, PN420 and 16QAM with EQ off)
  • Analysis bandwidth: up to 25 MHz

Other features

  • License key upgradable

The DTMB (CTTB) measurement application for the CXA is one of more than 25 measurement applications in the Keysight X-Series, evolutionary approach to signal analysis that spans instrumentation, measurements, and software, transforming the X-Series signal analyzers into standards-based transmitter testers. The DTMB (CTTB) application provides fast, one-button standards-based power and modulation analysis capabilities to help your design, evaluation, and manufacturing of DTMB (CTTB) modulators, transmitters, amplifiers, tuners, and gap-fillers/repeaters.

RF transmitters, modulators, and components testing

  • One-button measurement helps improve speed with the standard presets
  • Multiple modulation quality measurements help test the DUT’s full performance
  • Advanced settings help R&D engineers with troubleshooting
  • Remote SCPI command increase the manufacturing test efficiency
