Acquisition:Spectrum:Span

Short Name: Spectrum.Span

Specifies the frequency range of the computed spectrum. If you specify a center frequency of 1 GHz and span of 100 MHz, the spectrum ranges from 950 MHz to 1050 MHz after zoom processing. This value may be coerced based on hardware settings and downconversion specifications.

Note  If you configure the spectrum span (stop frequency – start frequency) to a value larger than 20 MHz, RFSA performs multiple acquisitions and combines them into a spectrum of the size you requested.
