RF A = R&S SMW front panel connector
RF = RF signal at the R&S SZU output (front panel connector)
I/Q, I/Q BAR OUT = Differential analog I/Q outputs
BB I/Q, BB I/Q Bar In = Differential analog I/Q inputs
USB = USB control signal for the USB connector of the R&S SMW to the USB Device con-
nector of R&S SZU
To connect and configure each of the R&S SZU to the R&S SMW, proceed as follows:
1. Use suitable cables and connect the R&S SZU to the I/Q and I/Q BAR output con-
nectors of the R&S SMW.
2. Connect the RF A output to the LO IN of the R&S SZU.
3. Connect a USB cable to the USB connector and the USB DEVICE connector of
R&S SZU.
4. Switch on the R&S SZU.
5. Connect the R&S SZU to the DUT.
6. Open the "Taskbar > System Config > System Configuration > External RF und
I/Q" dialog.
Select "I/Q OUT1 > External Instrument > Config".
The R&S SMW detects the R&S SZU automatically.
7. In the "External Instrument Configuration" dialog, select "External Instrument >
SZU (<Serial Number>)".
Set "I/Q Output Type > Differential".
8. Select "Apply".
The "System Config > System Configuration > External RF und I/Q" dialog displays
the settings of the connected external instrument.
9. In the "External RF und I/Q", select "Auto Connect > On".
Select "Preset behavior: Keep connections to external instruments > On".
