W6155A ISDB-T/Tmm Measurement Application for CXA

The W6155A is discontinued after June 1, 2019. The replacement model is the N6155EM0D X-Series Measurement Application with KeysightCare.

Signal analysis

• ISDB-T, ISDB-T_B, ISDB-T_SB, and ISDB-Tmm standards 
• Transmitter RF measurement
• One-button measurements with pass/fail per the standard, plus auto detection
• Runs inside CXA signal analyzer

Measurements

• Power measurement: channel power, shoulder attenuation, ACP, CCDF, OBW, SEM
• Modulation accuracy measurement: constellation, TMCC decoding, AC decoding, MER/EVM (MER RMS/peak, MER by subcarriers, MER by layer A/B/C, MER by data, pilot, TMCC, and AC), MER vs. Segments, frequency error, clock error, amplitude error, phase error, quadrature error, and amplitude imbalance
• Channel frequency response, spectral flatness, channel impulse response (supports SFN test for pre-, post-, 0-dB, and out-of-GI echo scenarios)
• Auto detection or manual settings of ISDB-T, ISDB-T_SB, or ISDB-Tmm signal; provides advanced settings like equalization switch, demodulation symbols, out-of-band filtering, and clock rate

Performance

• Power accuracy: up to ±0.61 dB (95^th percentile)
• Shoulder attenuation dynamic range: up to 78.9 dB (86.6 dB typical)
• MER floor: up to 40.1 dB (13 segments and 64QAM with EQ off) for ISDB-T; up to 40.1 dB (33 segments with EQ off) for ISDB-Tmm
• Analysis bandwidth: up to 25 MHz (ISDB-Tmm requires 25 MHz analysis bandwidth)

Other features

• License key upgradable
• Fixed and transportable license available
• SCPI remote user interface

The ISDB-T/Tmm measurement application for 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 ISDB-T application provides fast, one-button standards-based power and modulation analysis capabilities to help your design, evaluation, and manufacturing of ISDB-T modulators, transmitters, amplifiers, tuners, and gap-fillers/repeaters. The measurement application complies with ISDB-T, ISDB-T_B, ISDB-T_SB and ISDB-Tmm terrestrial digital sound broadcasting specifications

RF transmitters, modulators, and components testing

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