State
Activate signal transmission.
This function applies to R&S DigIConf, since R&S signal generators and analyzers start
signal transmission directly in the instrument.
Note: Data transmission requires that the respective breakout board is connected.

Logic Type
Selects the digital signaling system used for transmitting the baseband signal from or to
the DUT.
Note: SCPI notation varies
The SCPI notation varies, when you remotely control the R&S EX-IQ-BOX on R&S EX-
IQ-BOX or R&S signal generators and R&S signal analyzers.
Follow the command link below for description of the command and its syntax in detail.
"LVDS" The signal is transmitted by using the signaling system LVDS ( L ow
V oltage D ifferential S ignaling).
"LVTTL" The signal is transmitted by using LVTTL technology ( L ow V oltage
T ransistor T ransistor L ogic) with a voltage level of 3.3 V.
"x.x V CMOS" The signal is transmitted by using the CMOS Technology ( C omple-
mentary M etal O xid S emiconductor). x.x represents the voltage level
provided in the list.
"x.x V SSI"
The signal is transmitted by using the SSI Technology ( S erial S ynch-
ronuos I nterface). Voltage levels are 1.5 V and 1.8 V.

Direction
Selects the direction of signal transmission from the DUT to R&S EX-IQ-BOX or vice
versa.
Note:
Setting the transmission path and starting depend on the activating device
●
R&S DigIConf
Signal direction is selected in the "Direction" field of the R&S EX-IQ-BOX "User
Defined" settings dialog. Select "Transmitter/Receiver" in the drop down list.
The transmission is activated by switching On the "State" button.
●
R&S signal analyzers
Signal direction is selected in the "Select Type" field of the "EXIQ-Box Settings" dia-
log. Select "Transmitter/Receiver" in the drop down list, as described in
​
chap-
ter 6.1.1.6, "Dialogs" , on page 57.
To toggle between the different types, press the "TX SETTINGS" or "RX SET-
TINGS" softkey to select the type from the combo box.
●
R&S signal generators
The direction of signal transmission is distinguished as input and output settings dia-
logs "EX-IQ-BOX BBIN" and "EX-IQ-BOX BBOUT". Therefore, "Direction" is not
required in control by for R&S signal generators.
