Description
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. |
