ral:GATEWIDTH, MATH<x>:SPECTral:CENTER,
MATH<x>:SPECTral:SPAN, MATH<x>:SPECTral:WINdow
Arguments
<NR3> is the desired resolution bandwidth value. Units are represented in Hertz.
Examples
MATH1:SPECTRAL:RESBW 250E3 sets the resolution bandwidth to the attainable
value that is close to 250 kHz.
MATH1:SPECTRAL:RESBW? might return :MATH1:SPECTRAL:RESBW
1.0002E+06
, indicating the actual resolution bandwidth value obtained from
the spectral analyzer.
MATH<x>:SPECTral:SPAN
This command sets the ceiling of the frequency span to a value that is closest to
the specified value. The query form of this command returns the current span
value for specified math waveform. The Math waveform is specified by x, which
ranges from 1 through 4. This command is equal to s electing Spectral Setup from
the Math menu and then entering a value in the Freq Span box.

MATH<x>:SPECTral:SPAN?
Related Commands
MATH<x>:SPECTral:CENTER
Arguments
<NR3> specifies the frequency span of the output data vector from the spectral
analyzer.
FULL sets the top of the span to 1/2 the sample rate and sets the center frequency
to 1/2 the span.
Examples
MATH1:SPECTRAL:SPAN FULL sets the top of the span to 1/2 the sample rate and
sets the c enter frequency to 1/2 the span.
MATH1:SPECTRAL:SPAN 2.56E6 sets the top of the span to a value that is
closest to 2.56 MHz.
MATH1:SPECTRAL:SPAN? might return :MATH1:SPECTR AL:SPAN
1.2500E+09
, indicating the actual span v alue obtained by the spectral analyzer.
