To Set the Center Frequency
Press Parameter
→ Center Frequency, to set the center frequency. The range
of center frequency is 0Hz ~ 500MHz. If the center frequency is 0Hz, the two
channels will output the IQ baseband signal. If the center frequency is not zero
the two channels will output an intermediate frequency (IF) IQ modulation
signal whose center frequency is the intermediate frequency. The figure below
shows the diagram of the IQ modulator in the SDG6000X Figure 2-31.

To Set the Fsymb/Fs
Fsymb (symbol rate) can be transformed to Fs (sampling frequency)
according to the Oversampling factor (Pts/Symbol). The formula below shows
the relationship:
Fs=Fsymb*(Pts/Symbol)
The range of Fs is from 500 Hz to 75 MHz.
Press Parameter
→ Fsymb, to set the Fsymb parameter. If Fs is the desired
parameter, press Fsymb/Fs again to enter the Fs Figure 2-32
