Start / Stop Freq and Center / Span
These settings control the frequency range being swept.
Note: “Center / Span” are used in this manual, but using “Start / Stop
Freq” achieves the same results.
When the soft key is pressed, the corresponding selection is highlighted. The fol-
lowing can then be performed:
 Up/Down Arrow Keys: Increase and decrease the frequency or span in
small steps.
 Left/Right Arrow Keys: Increase and decrease the frequency or span in
large steps.
 Thumbwheel: Each click of the thumbwheel changes the frequency or
span by the value of the “Wheel Step” soft key.
 Number Keys: Press any key to open a box to type the new frequency
into. If a mistake is made, press “Esc/Back.” When done, press enter
(to keep the same frequency units) or press the soft key corresponding
to the desired units.
Wheel Step
When a frequency function is active and the thumbwheel is turned, the value
will change in steps of the “Wheel Step”. After pressing the “Wheel Step” soft
key to highlight it, the following is enabled:
 Up/Down Arrow Keys and Thumbwheel: Change the step value by 10
kHz per press of the arrow key or click of the thumbwheel.
 Left/Right Arrow Keys: Change the step value by 1 MHz per press of
the arrow key.
 Number Keys: Press any key to open a box to type the new frequency
into. When done, press enter (to keep the same frequency units) or
press the soft key corresponding to the desired units.
Full Span
Sets the Start Freq to 0 and the Stop Freq to the maximum frequency of the
unit.
Note: The accuracy spec does not apply below the minimum freq of
the unit (100 kHz). The start frequency can be set to 0 as a convenience.
Freq List
Opens a list of predefined frequency bands. Use the up/down arrows and thumb-
wheel to scroll to the desired band then press the “Select” soft key to use it.
Recently used bands are displayed at the top of the list.
