24 Getting Started Guide

1 Quick-Start

Port Configuration

Any of the TRXs four RF ports can be configured as an input port (accepting a signal to

be analyzed) or as an output port (providing an RF stimulus). Two of the ports (RFIO 1

and RFIO 2) can also be used in full-duplex mode (that is, with a single port used for

both input and output simultaneously). The various possible configurations are described

here.

Full Duplex Port Setup (RFIO 1 and RFIO 2)

Ports RFIO 1 and RFIO 2 connect to a splitter/combiner rather than a switch, so they can

be used in full duplex mode.

To use the RFIO 1 port as the input and output, set up the RF Input using this menu

setting or its equivalent command:

Input/Output > RF Input > RF Input Port > RFIO 1

Command:

:FEED:RF:PORT RFIO1

Then set up the RF Output using this menu setting or its equivalent command:

Input/Output > More > RF Output & Test Set Config > RF Output Port > RFIO 1

Command:

:FEED:RF:PORT:OUTP RFIO1
