SPAN
This hardkey accesses the softkey submenu of span
functions. Pressing [SPAN] allows you to change the
frequency range. The frequency-span readout describes
the total displayed frequency range. To determine
frequency span per horizontal graticule division (when in
linear frequency scale type), divide the frequency span
by 10.
