[:SENSe]:SPECtrum:FREQuency:SPAN <freq>

(Read-Write) Set and query the frequency span in IQA (spectrum only). This is translated to the required Digital IF bandwidth for the FFT analysis. The analyzer’s Digital IF bandwidth is always equal to this value. The maximum span is equal to the maximum bandwidths of the IF Paths.

Relevant Modes

FOPS (Opt 208), IQA (Opt.351) - (Spectrum Only )

Parameters

<frequency>

Span Frequency in Hz.

Minimum: 10 Hz

Maximum: 10 MHz

Couplings

Changing the span causes the IFBW and SampleRate change automatically,

Span = IFBW, Sample Rate = 1.25 * IFBW

Res BW = Span /50, if Resolution Bandwidth = Auto.
