The modulation frequency will be 72MHz/(step count*I&Q sample amount)

If step count=200, and I&Q sample amount=36, modulation frequency will be 10KHz.

Any analog modulation and low frequency signal can be generated by I&Q raw data file, just define the I&Q raw 
data by math formula, you can generate any kind of waveform, the working method of I&Q raw data file is same 

as 

Arbitrary Signal Generator, but it have two channels to generate signal. 

 

4.22 Data stream file

Data stream file will be include input data, I&Q pattern and some setting. 

When you open the data stream file, you will find four section:
1: Data input

2: S/P setting
3: converter setting

4: I&Q pattern data
the file format will be shown at following:
