Selecting the frequency step mode
The frequency step mode defines the way the measurement frequencies are selected
within a scan range.
Note that the frequency stepsize for time domain scans is always selected automati-
cally.
"AUTO"
Linear frequency steps: the Step Size is coupled to the current reso-
lution bandwidth and is about a third of the resolution bandwidth.
In this way, the probability to detect all signals in the scan range is
very high.
"LIN"
Linear frequency steps: the Step Size is a fix value in Hz.
"LOG"
Logarithmic frequency steps: the Step Size is a percentage of the
current frequency.

Displaying range bars
The range bar is a green bar displayed at the bottom of the scan diagram. You can turn
it on or off as you like with the "Show Range Bars" toggle button.
The range bar carries various useful information.
●
The shade of green shows the measurement progress.
– Dark green
Indicates that the scan of the corresponding scan range is done.
– Light green
Indicates that the scan of the corresponding scan range is currently in pro-
gress.
If you interrupt the scan, the bar remains light green. The bar of the last scan
range also remains light green when the scan is done completely.
●
The bar contains the names of the corresponding scan ranges as defined in the
scan table (for example "Range 1", "Range 2", etc.).

Configuring scan ranges
The main part of the scan table contains the configuration for each scan range. Each
column of the table represents one scan range (labeled "Range 1", "Range 2", etc. by
default).
You can change the labels of the scan ranges and assign a custom name to each
range. When you select the pencil icon ( ), you can edit the range labels. To stop edit-
ing, select the pencil icon again.
For each scan range, you can customize the following parameters.
