Tip: You can lock the frequency with the corresponding button in the toolbar. If you turn
on the frequency lock, the frequency does not change when you turn the rotary knob.
Changing the frequency with the cursor keys or the numeric keys still works.
Remote command:
[SENSe:]FREQuency:CENTer

Synchronizing the receiver frequency to the marker frequency ← Receiver Fre-
quency
When you are using a marker in the "Scan" result display, you can synchronize the
receiver frequency with the current marker position by just moving the marker.
The R&S ESW provides two methods to synchronize marker and receiver frequency.
●
"Marker Tracking"
Tracks the marker position when you move the marker and automatically synchro-
nizes the receiver frequency with the new marker position.
In that case, the bargraph always shows the level at the current marker position.
●
"Tune to Marker"
Synchronizes the receiver frequency and the current marker position once.
(In fact, this function only has an effect when "Marker Tracking" is turned off,
because otherwise, the marker position and frequency are synchronized automati-
cally.)
The R&S ESW always synchronizes to the position of the currently selected marker,
even if it is a relative delta marker.
The "Marker Tracking" and "Tune to Marker" softkeys are available in the "Marker To"
softkey menu (accessible via the [MKR
➙
] key).
Remote command:
Marker tracking:

Start / Stop Frequency
Defines the start and stop frequencies for the scan.
The range for the start frequency is f
min
to (f
max
- 10 Hz).
The range for the stop frequency is (f
min
+ 10 Hz) to f
max
.
f
min
and f
max
are defined in the datasheet.
Remote command:
Start frequency:

Stop frequency:
[SENSe:]FREQuency:STOP

Frequency Axis Scale
Selects the scale of the frequency axis.
More information
"Linear" Selects a linear scaling of the frequency axis.
"Logarithmic" Selects a logarithmic scaling of the frequency axis.
