3.9.11 How to Connect an R&S EX-IQ-BOX
Transmission of digital I/Q signals to a DUT requires that the signals are adjusted to
the type of interface, including its physical properties, and to the corresponding trans-
mission protocol. While Rohde & Schwarz instruments generally communicate via a
proprietary transmission protocol that is based on LVDS, many different interfaces and
communication protocols have evolved in digital I/Q transmission.
To meet many of these variants in a convenient way, you can use the R&S EX-IQ-BOX
as a downstream converter. The R&S EX-IQ-BOX is a configurable digital interface
module, designed to convert digital I/Q signals of the Rohde & Schwarz instruments
into user defined or standardized signal formats. This is done by so-called breakout
boards, which adjust the signal physically.

Basic test setup with the R&S EX-IQ-BOX
The Figure 3-28 shows the cabling of a basic test setup with the R&S SMW, a connec-
ted R&S EX-IQ-BOX and a DUT. The R&S EX-IQ-BOX is configured via USB by the
digital interface configuration software R&S DigIConf, running on a PC. The R&S EX-
IQ-BOX operates in transmitter mode from the R&S SMW to the DUT.

This section describes how to configure a basic setup with the R&S SMW and R&S
EX-IQ-BOX, including the cabling, installing the configuration software, and connecting
the instruments.
For more information, refer to the R&S EX-IQ-BOX Operating Manual.
To set up the R&S EX-IQ-BOX and R&S DigIConf
1. Disconnect all R&S EX-IQ-BOX instruments from controller PC.
