To connect a receiver antenna
► Connect the receiver antenna to the "RF1 IN/OUT" or the "RF2 IN" interface
on the front panel of the R&S EDS300.
The "RF2 IN" connector provides a higher sensitivity.
To connect a transmit antenna
1. Connect the transmit antenna to the "RF1 IN/OUT" on the front panel of the
R&S EDS300.
2. If necessary, insert an attenuation element between the laboratory equipment
and the R&S EDS300 to prevent destruction of laboratory equipment in labo-
ratory operation.
The R&S EDS300 transmitter antenna provides a maximum output of 500 W
(57 dBm).
4.8.2 Connecting a suppressor line
Using a bi-directional suppressor line, the instruments in an aircraft send signals
to each other. While a signal is being sent on the suppressor line, no other instru-
ment can send a signal at the same time. Any receivers are switched off tempora-
rily to avoid overloading.
► Connect the suppressor line to the "SUPPRESS IN / OUT" interface on the
rear panel of the R&S EDS300 (see Chapter 5.2.2, "SUPPRESS IN / OUT
connector" , on page 32).
4.8.3 Connecting a GPS receiver
You can connect a GPS receiver to the RS232 interface on the rear panel of the
R&S
EDS300 (see also Chapter 5.2.9, "RS232 GPS interface" , on page 33).
GPS support requires option R&S EDS-K3.
If available, the NMEA protocol data provided by the GPS receiver is displayed
and stored with the recorded data.
