07 | Keysight | ISDB-T/Tmm X-Series Measurement Application N6155A & W6155A - Technical Overview
Measurement Details
Most of the RF transmitter measurements as defined by the ISDB-T standard, as well as
a wide range of additional measurements and analysis tools, are available with a press
of a button (Table 3). These measurements are fully remote controllable via the IEC/IEEE
bus or LAN, using SCPI commands.
Analog baseband measurements are available on the Keysight PXA or MXA signal ana-
lyzer equipped with BBIQ hardware. Supported baseband measurements include all of
the modulation quality plus I/Q waveform measurements.
