Entering the center-frequency stepsize
¾ Press the CF STEPSIZE key.
A submenu above the softkey label opens. The box contains various stepsize setting options.
With 0.1 x SPAN
(default setting), the stepsize is equal
to 10 % of the span (= 1 division on the vertical scale).
With = CENTER,
the stepsize is equal to center
frequency. This setting is ideal for measurements on
harmonics. On each frequency increment, the center
frequency moves to the next harmonic.
With MANUAL...
you can select any stepsize. This
makes it easy to investigate spectra with frequencies
at constant intervals.
¾ Make the selection you want with the rotary knob
or the cursor keys and terminate with the ENTER
key.
If you select "0.1 x SPAN" or "= CENTER", the R&S FSH makes the setting directly itself. If you select
"MANUAL...", the value entry box opens and indicates the current stepsize.
¾ Using the rotary knob, the cursor keys or numeric entry, change the stepsize.
¾ When you have entered the stepsize you want, confirm by pressing the ENTER key or by pressing
the CF STEPSIZE softkey.
