Function
: The R&S
QAT has one or two antenna lines. The first antenna line is always
installed, while the second line is optional (R&S
QAT-B2).
Each antenna line has 11 SMA connectors with the following functionality.
●
5 x receiver outputs for a connection to a radar echo generator.
The connectors are labeled "Rx A" to "Rx E".
●
4 x transmitter inputs for a connection to a radar echo generator.
The connectors are labeled "Tx A" to "Tx D".
●
1 x transmitter input for a connection to a radar echo generator
The connector is labeled "Tx
∑
".
●
1 x receiver output that you can use to:
–
feed a single receive signal into the radar echo generator
–
connect another receiving device to analyze the received signal, like a spec-
trum analyzer.
The connector is labeled "Rx Select".
For a more comprehensive description and application of the connectors in the
antenna lines, see
Chapter 5, "Simulating radar objects"
Mapping of connectors to antennas
The R&S
QAT has four antenna segments ("A" to "D") that receive and transmit signals
and a fifth segment in the center that only contains a receive antenna ("E"). Depending
