Frequency Keys
ISPAN)
Pressing the (SPAN) key puts the instrument into the sweep mode and allows
the span of the sweep to be changed.
This key puts the instrument into sweep mode and displays the center
frequency and frequency span in the FREQUENCY display. The CF and
SPAN annunciators are turned on. The frequency span becomes the active
parameter. If the span is changed to a value that would put one end of the
sweep beyond the legal range of the start and stop frequencies, then the
center frequency is adjusted so that the end of the sweep is a valid frequency,
while keeping the span the same. The span frequency is always coupled to
previously-set start and stop frequencies by the equation:
SPAN= (STOP
-
START).
