7 Protocol Settings
"Protocol Settings" describes the parameters and settings of the respective transmission
protocols. It contains all parameters that you have in the GUI dialogs, and provides the
corresponding remote control command linked to the command description. Depending
on the protocol type, you can find additional information, such as information on the
transmission protocol or on operating elements of the breakout boards, or special fea-
tures to the remote commands.
With the exception of a few specific test setups, the parameters of the R&S EX-IQ-BOX
are set by a PC via the configuration software R&S DigIConf.
Important note to the command syntax in User defined applications
The previous version of the R&S EX-IQ-BOX, model 1409.5505.02 only supports test
setups with User Defined protocols. As a special feature, it can be controlled directly by
an instrument. In this mode, the remote-control commands differ in the notation, depend-
ing on the device that controls the R&S
EX-IQ-BOX.
The commands listed in the User Defined GUI description always refer to R&S DigI-
Conf, since it is used in almost all applications.
If you run an R&S
EX-IQ-BOX, model 1409.5505.02 directly with an R&S instrument, you
can find the appropriate command syntax by following the link of the SCPI command.

chapter 7.1, "User Defined" , on page 95 describes the parameters of user defined
applications, i.e. settings for serial or parallel transmission of I/Q signals to a DUT,
including variable clock modes, various data rates as well as different logical signal
levels. This section applies to applications using the breakout boards included in
delivery.

chapter 7.2, "CPRI" , on page 126 contains a general overview of the standard inter-

additionally enables you to set "Control&Management" parameters, "Vendor Data"
management, "Waveform Playback" and "Recording" memory.
7.1 User Defined
In modern communication systems it is communicated increasingly via digital baseband
interfaces, so called I/Q links. Therefore some standardized interfaces like CPRI were
developed. These standardized interfaces are covered by special purpose options, which
are additionally available for the R&S
EX-IQ-BOX.
But also without any additional option, the R&S EX-IQ-BOX covers a large number of
different digital I/Q interfaces by using user-specific breakout boards. This general oper-
