Siglent's own figures, as its documents state them; each links to the page it is on.
Shows how much signal there is at each frequency; its tracking generator sends a sine wave that sweeps along with it, so it can also measure a circuit's frequency response.
Its tracking generator sweeps a sine across the scope's band for the bandwidth and band-limit measurements.
Its tracking generator sends a sine that sweeps with the analyzer: into a scope channel it is a swept source for the bandwidth and band-limit measurements, independent of the scopes' own generators.
The tests we will run with it next; the results will appear here.
