06 | Keysight | CMMB X-Series Measurement Application N6158A & W6158A - Technical Overview
Measurement details
Measurements as defined by the CMMB
standard, as well as a wide range of ad-
ditional measurements and analysis tools,
are available with a press of a button
(Table 2). These measurements are fully
remote controllable via the IEC/IEEE bus
or LAN, using SCPI commands.
Analog baseband measurements are avail-
able on the PXA or MXA signal analyzer
equipped with BBIQ hardware. Supported
baseband measurements include all of the
modulation quality plus I/Q wave-form and
CCDF measurements.
