Product Overview

The ISDB-T/Tmm measurement application is one of more than 25 measurement applications in the Keysight X-Series, an 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_SBand ISDB-Tmm terrestrial digital sound broadcasting specifications.

Key Features
Signal Analysis	ISDB-T, ISDB-T_B, ISDB-T_SB and ISDB-Tmm standards Transmitter RF measurement, analog baseband measurements with PXA BBIQ or MXA BBIQ hardware One-button measurements with pass/fail per the standard, plus auto detection Runs inside PXA, MXA and EXA signal analyzers
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 (support 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 (Hardware Dependent)	Power accuracy: up to ±0.19 dB (95^th percentile) Shoulder attenuation dynamic range: up to 92.9 dB (98.7 dB typical) MER floor: up to 49 dB (13 segments and 64QAM with EQ off) for ISDB-T; up to 50 dB (33 segment with EQ off) for ISDB-Tmm Analysis bandwidth: PXA/MXA up to 160 MHz; EXA up to 40 MHz
