Rohde & Schwarz R&S ® SMU200A Vector Signal Generator 27
The frequency offset can be used to shift the center frequency of the modulation signal
in the baseband. The restrictions caused by the modulation bandwidth apply.

In the case of serial transmission, the symbol strobe marks the LSB of the symbol, and
the maximum symbol rate is limited by the data rate of the interface.
serial
word width 1 bit to 10 bit
bit rate max. 60 MHz
parallel
word width 1 bit to 10 bit
Data sources
symbol rate max. 25 MHz
In internal clock mode, a trigger event restarts the clock generation. The clock phase is
then synchronous with the trigger (with a certain timing uncertainty).
In external clock mode, the trigger event is synchronized to the symbol clock.
