Frequency Stepsize
Defines the stepsize by which the receiver frequency is increased or decreased when
you change it with the arrow keys or the rotary knob.
Note that the rotary knob and the arrow keys apply different steps.
When you turn on "Wheel = Up / Down", the rotary knob and cursor keys have the
same step size (that of the cursor keys).
"Coarse"
The stepsize is coupled to the receiver frequency.
●
When you change the frequency with the rotary knob, the
R&S ESW increases or decreases the 4th digit of the receiver fre-
quency.
●
When you change the frequency with the arrow keys, the
R&S ESW increases or decreases the 2nd digit of the receiver
frequency.
"Fine"
The stepsize is coupled to the receiver frequency.
●
When you change the frequency with the rotary knob, the
R&S ESW increases or decreases the 7th digit of the receiver fre-
quency.
●
When you change the frequency with the arrow keys, the
R&S ESW increases or decreases the 5th digit of the receiver fre-
quency.
"Manual"
The stepsize is a fixed custom value.
●
When you change the frequency with the rotary knob, the
R&S ESW increases or decreases the frequency by 10 % of the
manual stepsize.
●
When you change the frequency with the arrow keys, the
R&S ESW increases or decreases the frequency by the manual
stepsize.
"Frequency =
Stepsize"
The stepsize is equal to the current receiver frequency.
This option is useful for measurements of the harmonic content of a
signal. Each change of the frequency selects the next harmonic.
"<x> * Meas
BW"
The stepsize is a percentage of the measurement bandwidth (10 %,
50 % or a custom percentage).

Couple Bargraph Settings
Couples or decouples the bargraph settings to the scan settings (or scan range if you
are using a scan table).
"Off"
Bargraph settings and scan settings are independent.
"Last Scan"
Uses the configuration of the last scan.
"Scan Table"
Uses the current configuration of the scan table, if you have changed
it since the last scan.
(If you have not changed anything, the configuration of the last scan
is still in effect.)
