reduction in data transfer rate

Quote from Almer on 11/09/2022, 14:48Hi AARONIA team
I want to receive data at low rates so lower capacity of USB stream be occupied.
I though this can be achieved by changing span frequency e.g. if in full span data rate is 352 MByte/sec in USB or 92 M sample/sec for IQ samples I expect using half of these recourses for span 1/2 but even if I use much lower spans, data rate are not changing.
so this way first what is the benefit of reducing span
and second Is there any way to reduce recourse usage?
,regards

Better is to use Spectra instead:
