FE50DTR

Manual 1179.3180.02 ─ 02

Operating the instrument

You can operate the R&S

FE50DTR in single receive mode (Rx), single transmit

mode (Tx) or simultaneous mode. In simultaneous mode, the R&S

FE50DTR

operates in Rx and Tx mode simultaneously also referring to dual transmit receive

DTR

operation.

6.1

Operating the R&S

FE50DTR in Rx mode

In Rx mode, the R&S

FE50DTR receives a high-frequency RF signal from the

device under test (DUT). It downconverts this signal using its own internal local
oscillator to an intermediate frequency (IF) signal that is a low-frequency signal.
The R&S

FE50DTR outputs and transmits the IF signal to the vector signal ana-

lyzer.

are analogous.

To connect the R&S

FE50DTR for Rx mode

The R&S

FE50DTR is

connected to power

and

switched on

► Connect all connectors for connections between the R&S
