Channel and Frequency Configuration
The ILS Localizer and Glidepath measurements can detect both course and clearance
carriers simultaneously. Alternatively, the individual carriers can be measured only, or
any one or two user-defined frequencies. By default, a wideband measurement is per-
formed. The available measurement settings depend on the selected channel and fre-
quency configuration.

1F/2F
Selects the number of frequencies or channels to be measured.
"1F"
One frequency only is measured, namely the nominal frequency,
which is also the center frequency.
The nominal frequency is configured by the
settings.
"2F"
Two frequencies are measured at the same time. Which frequencies
are measured is configured by the
Channel Frequency Configuration
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
