●
Always use cables of the same length.
Use as short as possible cables.
T = T-connector
R&S SMW#1 = Trigger source
R&S SMW#2, R&S SMW#n = N number of instruments
USER 3 = Front panel connector
USER 6 = Rear panel connector on the R&S SMW#1 (trigger source)
<- = Executes trigger manually
Required configurations:
●
In all R&S SMW:
– Use the default settings "User 3 > Direction = Input" and "Signal = Global Trig-
ger 1".
– Select "Baseband > ... > Trigger In > Trigger Source > Ext. Global Trigger 1".
●
In R&S SMW#1, set "System Config. > Setup > Global Connectors > User 6 >
Direction = Output".
Set "User 6 > Signal = Manual Trigger".
To trigger the signal generation form R&S SMW#1, select "Global Connectors > Exe-
cute Trigger".
Alternatively, send the remote control command :OUTPut:USER<ch>:TRIGger[:
IMMediate].
R&S SMW#1 generates a short high signal and outputs it at the USER 6 connector.
The signal acts as a common external trigger signal for all R&S SMW and all base-
bands.
9.4 Control and Operation of External Instruments
In test scenarios that require more than two RF signals, the I/Q analog and digital out-
put signal can be routed to and processed by external instruments. Typically, the gen-
erated I/Q streams are further processed by R&S SGT or R&S SGS.
Other applications like the radar echo generation or the generation of WLAN 802.11ad
signals at 58.3 GHz require connected R&S FSW or R&S SZU.
