describes the total displayed frequency range; to determine frequency
span per horizontal graticule division, divide the frequency span by 10.

on the peak, it places a marker there, turns on the signal-track
function, and activates the span function. The analyzer then reduces
the span in steps, keeping the signal centered on the screen until the
optimum span is reached. The analyzer is left in

units of time), like a conventional oscilloscope.
Sweep times faster than those in the frequency domain display mode
are available if Option AYX or B7D are installed.
Resolution Bandwidths less than 1 kHz are unavailable when in zero
span if the sweep time is being achieved by utilizing the Option AYX or
B7D.
The minimum number of sweep points in zero span is 2.
