06 | Keysight | DTMB (CTTB) X-Series Measurement Application N6156A & W6156A - Technical Overview
Measurement details
All of the RF transmitter measure-
ments as defined by the DTMB
(CTTB) standard, as well as a wide
range of additional measurements
and analysis tools, are available with
a press of a button (Table 2). These
measurements are fully remote con-
trollable via the IEC/IEEE bus or LAN,
using SCPI commands.
Analog baseband measurements
are available on the PXA or MXA
signal analyzer equipped with BBIQ
hardware. Supported baseband mea-
surements include all of the modula-
tion quality plus I/Q waveform and
CCDF measurements.
