This is regarding the selection of best RBW for spectrum analyzer (PXA).
Span is 1GHz, number of sweep points 10001. I think PXA has 1001 display points or pixels.
In this case, bucket size is 100 KHz(1GHz/10001). RBW of 100 KHz will cover one bucket and 1 MHz will cover 10 buckets. Which is better RBW of 100 KHz or 1 MHz?. Or what is the logic for selecting best RBW?
