STEPSIZE
.The STEPSIZE opens a sub menu for setting the step size of the receive
frequency. The step size can be coupled to the set frequency or be manually
set to a fixed value. The softkeys of the submenu are mutually exclusive
selection switches. Only one switch can be activated at any one time.
AUTO
COARSE
If the AUTO COARSE softkey is activated, the receive
frequency is set in coarse steps. The 4th digit of the
selected frequency is varied.
IEC/IEEE-bus command --
AUTO
FINE
If the AUTO FINE softkey is activated, the receive
frequency is set in fine steps. he 7th digit of the selected
frequency is varied.
IEC/IEEE-bus command --
STEPSIZE
MANUAL
The STEPSIZE MANUAL softkey activates the entry
window for the input of a fixed step size.
IEC/IEEE-bus command FREQ:CENT:STEP 50 kHz
STEPSIZE
= FREQ
The STEPSIZE = FREQ softkey sets the step size to a
value equal to the receive frequency.
This function is especially useful during measurements of
the signal harmonic content, because, when entering the
receiver frequency, the receiver frequency of another
harmonic is selected with each stroke of the STEP key.

The START softkey opens a window where the start frequency of the scan
diagram can be entered.
