"2F CLR" Both the course and clearance frequencies are measured simultane-
ously. The results for both frequencies, as well as the sum of both,
are displayed in the RF Level display. Both frequencies are displayed
in the RF Spectrum preview. The numeric results are displayed for
the course frequency. To view the results for the course frequency,
switch to "2F CRS".
Note: Depending on the ILS system and the country, the course can
be the upper or lower frequency (see "Upper Freq" on page 58).
"Wide" A wideband measurement is performed around the nominal fre-
quency. The frequency range is defined by the
BW Wide ).

Carrier Configuration (1F/2F Config)
Access : [Config] > "1F/2F Config"
Access VNC : [s] > "F1"
Configures the carriers and frequencies for measurements on a single or two frequen-
cies (not wideband). Which settings are available depends on the
"1F/2F" on page 56.

CRS/CLR Carr
Defines whether the course and clearance carriers are determined automatically or
manually.
For automatic determination, both carriers are determined automatically and continu-
ously during the entire measurement.
You can define a threshold ( Carrier Thresh ) by which the power level for a carrier must
change before the carrier frequency is adapted. The other settings that define the fre-
quencies are disabled.
For manual determination, you must specify the frequencies as offsets to either direc-
tion of the nominal frequency.
