By default, the frequency axis has linear scaling. Logarithmic scaling of the frequency
axis, however, is common for EMI measurements over large frequency ranges as it
enhances the resolution of the lower frequencies. On the other hand, high frequencies
get more crowded and become harder to distinguish.
For more information see chapter 6.3.1.4, "Coping with Large Frequency Ranges -
Logarithmic Scaling" , on page 386.

5.13.4.3 LISN Control Settings
For measurements with power lines, the following settings are available for the
R&S
FSW to control which phase of the LISN is to be tested (e.g. for EMI measure-
ments). LISN control requires the EMI measurement (R&S FSW-K54) option.
The LISN control settings are available when you do one of the following:
●
If the EMI measurement is selected, press the MEAS CONFIG key, then select
"LISN Config".
●
Press the INPUT/OUTPUT key, then select "LISN Config".
●
In the "Overview", select "Output", then select "LISN Config".
