how to create 50KHz baseband signal from 0Khz baseband signal

[BrianZhang]

I use one PXI-5670 card, and I have a 0KHz baseband  signal, and I want to change it to 50KHz baseband signal. 

and then I will mix those 0KHz baseband signal and 50KHz baseband signal together into one baseband signal. 

How could I do?

Thanks a lot!

I think you are asking how to up convert a signal with 0 Hz carrier frequency to a signal with 50 Hz carrier frequency. You might need to see the example RFSG External AWG (5610).vi or RFSG External AWG (5611).vi in the Example Finder under Hardware Input and Output»Modular Instruments»NI-RFSG»Utilities.
