6.3 I/Q modulation and impairment settings

6.3.1 I/Q modulation

The R&S SGT offers I/Q modulation with:
●
External analog I/Q signals,
●
External digital signals,
●
Internal digital signals.
Either the external digital signal or the externally/internally generated baseband signal
is fed into the I/Q modulator ("I/Q Mod" function block).
The external signal is input via the I and Q connector and transferred directly to the I/Q
modulator ("I/Q Mod" function block). The external digital signal is configured in the
"BB In" function block (see
on page 262).
