To use this feature to synchronize the signal generation start in the basebands, pro-
ceed as follows:
1. In the first baseband enable:
a) "Baseband > Cust Dig Mod > Trigger In > Mode > Armed Auto"
b) "Baseband > Cust Dig Mod > Trigger In > Source > Internal"
2. In the second baseband enable:
a) "Baseband B > Cust Dig Mod > Trigger In > Mode > Armed Auto"
b) "Baseband B > Cust Dig Mod > Trigger In > Source > Internal (Baseband A)"
To use the external local trigger signal of the instrument
An external local trigger/clock signal is dedicated to the baseband board this signal is
supplied at (i.e. the board the local T/M/C connector is located).
To route internally this signal and to use it for synchronous triggering of all other base-
bands, proceed as follows:
1. Configure one of the local T/M connectors as input for the external local trigger sig-
nal:
a) "Baseband > Cust Dig Mod > Trigger In > Local Connector Settings"
b) In the "Local Connectors" dialog, enable "T/M 3 > Direction > Input" and "Signal
> Trigger"
2. In the first baseband enable:
a) "Baseband > Cust Dig Mod > Trigger In > Mode > Armed Auto"
b) "Baseband > Cust Dig Mod > Trigger In > Source > External Local Trigger"
3. In the second baseband enable:
a) "Baseband B > Cust Dig Mod > Trigger In > Mode > Armed Auto"
b) "Baseband B > Cust Dig Mod > Trigger In > Source > Internal (Baseband A)"
4. Use a suitable cable and connect the external trigger source to the T/M 3 connec-
tor of the R&S SMW.
See "To find out the physical location of the connector on the front/rear panel of the
instrument" on page 678.
The connector is located at the rear of the instrument, on the left part of the top-
most CODER board.
