5.1.1 RF connectors
Two bi-directional 1.85 mm female connectors "RF A"/"RF B" for input and output
of RF signals. RF signals have a frequency range of 36 GHz to 50 GHz.
●
"RF A": Input of the RF signal from the DUT. This signal is down-converted to
the frequency, which is measurable for the vector signal analyzer, e.g.,
R&S
FSV/A.
●
"RF B": Output of the RF signal to the DUT. This signal has a frequency value
as set at the vector signal generator, e.g., R&S
SMW.
How to: Chapter 4.8, "Connecting to SMA and 1.85 mm" , on page 17
RF signal center frequency
Consider that the RF signal has a certain bandwidth. So the ranges supported for
center frequency settings are smaller.
Rx mode and Tx mode
You can use the RF connectors for input ("Rx" = receive mode) and output ("Tx" =
transmit mode) of RF signals. At each connector, one of these modes can be
active at a time.
The modes are configurable at the R&S FSV/A (Rx mode) and R&S SMW (Tx
mode), see Chapter 6, "Operating the instrument" , on page 27.
5.1.2 Status LEDs
To the left of the RF connectors "RF A/RF B", there are LEDs indicating the oper-
ation mode ("Rx") and transmit mode ("Tx").
