"1F" One frequency only is measured, namely the nominal frequency,
which is also the center frequency.
The nominal frequency is configured by the
Channel Frequency Con-
figuration (CH FREQ) settings.
"2F" Two frequencies are measured at the same time. Which frequencies
are measured is configured by the
Channel Frequency Configuration
(CH FREQ) settings.
The numeric results are calculated as the sum of both frequencies. In
the RF Level display, the individual carriers are also indicated. In the
RF Spectrum preview, both carriers are displayed.
"2F CRS"
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 clearance frequency,
switch to "2F CLR"
Note: Depending on the ILS system and the country, the course can
be the upper or lower frequency (see "Upper Freq" on page 79).
"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 79).
"Wide" A wideband measurement is performed around the nominal fre-
quency. The frequency range is defined by the
IF BW .

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 76.
