The
Span
key activates the Span function and accesses the menu of
span functions. Pressing
Span
allows the user 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.
Span Zoom
finds the highest signal peak on the display. If a marker is not already
on the peak, it places a marker there, turns on the signal-track
function, and activates the span function. Span Zoom then requires the
user to enter a target span. Once entered, the analyzer reduces the
span in steps, keeping the signal centered on the screen until the
entered span is reached. Pressing
Span Zoom
performs the routine
similar to pressing the following keys:
Peak Search
