SPAN / X Scale
Span
Allows you to change the frequency range symmetrically about the center
frequency. The frequency-span readout describes the total displayed frequency
range. To determine frequency span per horizontal graticule division, divide the
frequency span by 10. Setting the span to 0 Hz puts the analyzer into zero span and
changes the horizontal axis from frequency to time.
