Hello,
We don’t have a function in the API that directly provides you the measurements that the “Measuring Receiver” does from Spike. I can tell you the general idea behind the it though.
You could reproduce it with the API by using basic sweep functionality with the flat-top window (default) and finding the peak value in the sweep. Reference level would then be used to adjust the sensitivity of the receiver as you adjust your input level to the receiver. You would want to measure the offset before and after a ref level change and include that offset in your final calculation.
A lower RBW on the sweep would get you finer frequency resolution if needed.
Let us know if you have additional questions.
Regards
