Generating external frontend RF signals

To configure and output the external frontend RF signal

The procedure assumes, that a remote control connection between R&S

 

SMW and

R&S

 

FE44S is established, see 

"To configure the R&S

 

SMW for frontend control"

on page 14.

1. Configure the output RF signal.

Once you connect the external frontend, the R&S

 

SMW sets the "RF Frequency" in

the taskbar automatically. In particular, the R&S

 

SMW sets the lower frequency of

"Frequency Band 1", i.e. 24

 

GHz.

2. In the status bar of the R&S

 

SMW, adjust the frequency and level of the RF signal,

that is output at the external frontend.

3. In the block diagram, select "RF > On".
