MATH<x>:SPECTral:SPAN
Description
This command sets the ceiling of the 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 speci-
fied by x, which ranges from 1 through 4 for four--channel instruments
or 1 through 2 for two--channel instruments.This command is equal to
selecting Spectral Setup from the Math menu and then entering a value
in the Freq Span box.

Arguments
H <NR3>
This specifies the frequency span of the output data vector from the
spectral analyzer.
H FULL
This sets the top of the span to 1/2 the sample rate and sets the center
frequency to 1/2 the span.
Example 1
MATH1:SPECTral:SPAN FULL
This command sets the top of the span to 1/2 the sample rate and sets
the center frequency to 1/2 the span.
Example 2

This command sets the top of the span to a value that is closest to 2.56
MHz.
