"RF In"
An RF signal is provided from the RX 1 In/RX 2 In connectors on the
front of the R&S
EVSG1000. They are connected to a receiving
antenna (max. +13
dBm). The antenna must correspond to the speci-
fied frequency range for the measurement.
"LF In"
An AF or low frequency signal is provided at the LF In input connector
on the rear side of the R&S
EVSG1000.
If both receivers are used, only one of them can be set to analyze
input from "LF In".
Analyzing LF input requires option R&S
EVSG1-K7.

Channel and Frequency Configuration
The ILS Localizer and Glidepath measurements can detect both course and clearance
carriers simultaneously. As an alternative, the individual carriers can be measured only,
or any one or two user-defined frequencies. By default, a wideband measurement is
performed to obtain an initial overview of the input signal and determine the basic sig-
nal characteristics. An autotune function is available to determine the precise frequen-
cies of the signal components automatically. Thus, the demodulation bandwidth can be
selected very precisely. The available measurement settings depend on the selected
channel and frequency configuration.

Selects the number of frequencies or channels to be measured.
For all frequencies except the wideband measurement, the autotune function automati-
cally determines the measurement frequency (see
