Sweep Points
Opens an edit dialog box to enter the number of measured values collected during a
single measurement.
For more information see "Setting the Number of Sweep Points" on page 298.
Remote command:
[SENSe:]SWEep:POINts on page 834
Freq (Lin Log)
Turns logarithmic scaling of the frequency axis on and off.
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.
Because it shows the lower frequencies more clearly, logarithmic scaling is used for
tests that focus on those frequencies, for example acoustic tests and measurements.
Remote command:

LISN Control
Opens a dialog box to control a LISN.
The dialog box contains the following elements.
●
LISN
Selects the V-network that you have in use. The R&S FSV-K54 supports the follow-
ing networks:
– R&S ESH3-Z5 and R&S ENV216 (two-line networks)
– R&S ESH-Z5, R&S ENV432 and R&S ENV4200 (four-line networks)
●
Phase
Selects the phase to be measured. Phase N and L1 are included in all four LISN.
Phase L2 and L3 are only included in four-line networks.
You can select one phase for a measurement only.
●
150 kHz HP
Turns on a 150 kHz highpass filter. The filter is available for the ENV 216 network
only.
