Two-path instruments: Frequency modulation and phase modulation are not compatible with I/Q modulation in the other RF path.

For simultaneous I/Q and frequency modulation, or simultaneous I/Q and phase modulation, the instrument must be equipped with a

two-path signal routing and baseband main module (R&S

SMW-B13T or R&S

SMW-B13XT option).

Instruments equipped with R&S

SMW-B2031, R&S

SMW-B2044, R&S

SMW-B2044N or R&S

SMW-B2044O in RF path B:

Amplitude modulation, frequency modulation and phase modulation are only possible in RF path A. When activating frequency or

phase modulation in RF path A, RF path B is switched off.
