Key Reference 5
Span
Activates the span function and accesses the submenu of span functions. Pressing [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 (when the frequency scale type is set to linear), divide the frequency span by 10.
Span
Allows you to enter a frequency span range value. Key access: [SPAN]
Full
Changes the span to full span showing the full frequency range of the analyzer.
Key access: [SPAN]
Zero
Changes the frequency span to zero. In this mode, the current center frequency is displayed in the time domain (the x axis is displayed in units of time), like a conventional oscilloscope.
Key access: [SPAN]
Last Span
Changes the span to the previous span setting. Key access: [SPAN]
