R&S EX-IQ-BOX and R&S DigIConf
The R&S EX-IQ-BOX is a configurable interface module that converts signal properties
and the transmission protocol of the R&S instruments into user-defined or standardized
signal formats and vice versa.
The EX-IQ-Box functionality is not supported for R&S FSVA/FSV models
1321.3008Kxx.
The latest R&S EX-IQ-BOX (model 1409.5505K04) provides the configuration software
R&S DigIConf which can be installed directly on the R&S FSVA/FSV. The software
R&S DigIConf (Digital Interface Configurator for the R&S EX-IQ-BOX, version 2.10 or
higher) controls the protocol, data and clock settings of the R&S EX-IQ-BOX independ-
ently from the connected R&S instrument. Besides basic functions of the user-defined
protocols, this software utility supports the settings for standardized protocols, as e.g.
CPRI, OBSAI or DigRF. Note that R&S DigIConf requires a USB connection (not
LAN!) to the R&S FSVA/FSV in addition to the R&S Digital I/Q Interface connec-
tion.
Remote control is possible and very simple. Remote commands for the R&S DigIConf
software always begin with SOURce:EBOX. Such commands are passed on from the
R&S FSVA/FSV to the R&S EX-IQ-BOX automatically via the USB connection.
A setup file, included in delivery, consists of an installation wizard, the executable pro-
gram and all necessary program and data files. The latest software versions can be
downloaded free of charge from the R&S website: www.rohde-schwarz.com/en/prod-
ucts/test_and_measurement/signal_generation/EX-IQ-Box. Simply execute the Setup
file and follow the instructions in the installation wizard.
For details on installation and operation of the R&S DigIConf software, see the
"R&S®EX-IQ-BOX Digital Interface Module R&S®DigIConf Software Operating Man-
ual".
3.7.2 Digital Input
Digital input is enabled by selecting the "Digital Baseband (I/Q)" input path in the "Sig-
nal Source" dialog box (available either in the "Measurement" menu of the "I/Q Ana-
lyzer" mode, or in the "Input/Output" menu of the base unit and some applications, see
"Signal Source" on page 429).
The digital input and output cannot be used simultaneously.
Signal Source
The device that provides digital input must be connected to the R&S Digital I/Q Inter-
face at the rear of the R&S FSVA/FSV. The signal source is then configured in the
"Signal Source" dialog box.
In the "Signal Source" dialog box the detected input device is indicated. For "Digital
Baseband (I/Q)" sources, you can configure the basic connection settings, e.g. the
input sample rate. Each time the device is disconnected or the configuration is
