6.4.2 COM Configuration
In this view, the measurements settings available for the currently active mode, can be
configured.
● Channel and Frequency Configuration ................................................................... 89
● Ampt ........................................................................................................................90
● Bandwidth (BW) ...................................................................................................... 92
● Setting the Measurement Time (MTime) .................................................................92
6.4.2.1 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.
● Channel Setup ........................................................................................................ 89
● Carrier Configuration (1F/2F Config) .......................................................................89
● Channel Frequency Configuration (CH FREQ) .......................................................90
Channel Setup
Access VNC : [m] > [F1]
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
Freq settings.
"2F" Two frequencies are measured at the same time. Which frequencies
are measured is configured by the
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.
Carrier Configuration (1F/2F Config)
Access VNC : [s] > "F1"
Configures the carriers and frequencies for measurements on a single or two frequen-
cies. Which settings are available depends on the
"1F/2F" on page 89.
Upper Carrier ................................................................................................................ 90
Lower Carrier ................................................................................................................ 90
1F Offset ........................................................................................................................90
