The parameters of these groups provide a large number of possible interface settings.
This way the R&S
EX-IQ-BOX can convert the R&S specific I/Q input/output to any digital
I/Q interface of the DUT.
Additionally to the interfaces parameters, R&S DigIConf provides a test function, to check
the signals between the R&S EX-IQ-BOX and the DUT. The R&S EX-IQ-BOX sends a
known test signal to the DUT, or, vice versa, the R&S EX-IQ-BOX receives a signal from
the DUT. This way, the I/Q interface to or from the DUT can be verified by performing bit
error rate tests.
7.1.2 Main Configuration Dialog
The main configuration dialog covers main controls and parameters for user-defined
applications. It sets the logical signal type, transmission path, and contains controls for
storing or loading settings and for activation. The main controls are always indicated,
independently fom the active subdialog.
Grouped by function, the subdialogs "Protocol", "Clock", "Data" and "Trigger" contain the
respective parameters.
R&S DigIConf shows the current settings for signal transmission also graphically, and
thus offers a convenient control of the configuration. I/Q data stream and clock signal to
or from the R&S
EX-IQ-BOX are shown schematically, and are adjusted by changes
simultaneously. The "Data" tab additionally shows the bit alignment graphically, and the
"Clock" tab the signal flow of the clock signal, corresponding to the currently selected
scenario.
The start window of "User Defined" indicates the "Protocol" tab which, besides of the
protocol parameters, also indicates the "Clock" and "Data" settings.
Device-specific dialog representation as well as command syntax
The dialogs in R&S signal generators are slightly different than in R&S DigIConf, e.g. they
do not need an input field for the transmission direction, since the connection of the
R&S
EX-IQ-BOX determines the transmisssion path automatically. Clock and data
parameters are also provided in separate tabs.
The commands in the following description relate to R&S
DigIConf. If you run an
R&S EX-IQ-BOX, model 1409.5505.02 directly with an R&S instrument, follow the link of
the SCPI command. There you will find a set of remote commands in order to get the
appropriate syntax for your application.
The following figures and description comprise the User Defined configuration dialogs
representative also for applications without R&S
DigIConf.
