Hello ssw,
Did you download the API files found at this link?
https://productbundlesdemo.kinsta.cloud/download/bbsa-application-programming-interface-for-windows-3264-bit/
In this download folder you will find two examples, simple_sweep_1 and simple_sweep_2. They will show you how to open, configure, and acquire data from the SA44B. You will use the saConfigCenterSpan function to control the frequency range of a sweep, and you will use the saGetSweep functions to acquire one sweep at your desired configuration. The example files should be able to be compiled and ran.
Hopefully this is enough to get you started. Contact us at support@signalhound.com if you have additional questions.
Regards,
A.J.
