W6156A DTMB (CTTB) Measurement Application for CXA

The W6156A is discontinued after June 1, 2019. The replacement model is the N6156EM0D X-Series Measurement Application with KeysightCare.

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

Measurements

• 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

Performance

• Power accuracy: up to ±0.61 dB (95^th 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
• Fixed and transportable license available
• SCPI remote user interface

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
