ISDB-T/Tmm Measurement Application

ISDB-T Measurement Application
Please call for availability
Live Inventory Check:


The ISDB-T/Tmm measurement application is one of more than 25 measurement applications in the Agilent 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-TB, ISDB-TSB 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

Key Specification

Signal Analysis

  • ISDB-T, ISDB-TB, ISDB-TSB and ISDB-Tmm standards   Latest Enhancements
  • 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


  • 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, channel impulse response, and spectral flatness
  • Auto detection or manual settings of ISDB-T, ISDB-TSB 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 (95th 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 up to 140 MHz; MXA/EXA up to 40 MHz

Other Features

  • License key upgradeable
  • Transportable license
  • SCPI remote user interface
  • Free trial license, try it for 14 days
