Operating external frontends, e.g. the R&S FE50DTR, requires a control connec-
tion (LAN) with the vector signal generator or vector signal analyzer. To establish
this connection, see the following sections:
●
"To control the R&S FE50DTR with a vector signal analyzer" on page 28
●
"To control the R&S FE50DTR with a vector signal generator" on page 33
Test setups
Test setups with dedicated connections depend on the operation mode of the
external frontend.
Figure 4-1 illustrates a typical test setup where the external
frontend operates in Tx (transmit) mode and Rx (receive) mode.
For detailed information on how the R&S FE50DTR is used in test setups and the
connections for each operation mode, see Chapter 6, "Operating the instrument" ,
on page 27.
Example: OTA measurement test setup for mmWave signals
Typically, mmWave signals are transmitted and received over-the-air (OTA) inside
an RF shield box.
The figure below illustrates a test setup with one external frontend connected to a
vector signal generator, vector signal analyzer and a cross-polarized Vivaldi
antenna. The antenna is mounted inside an RF shield box.
