Example: In the following, we assume that the two R&S SMW are connec-
ted and configured as required. The example uses R&S SGS as
RF extensions and the internal baseband signal of the first
R&S SMW as trigger source for both instruments. If you use
common external trigger source, consider to adapt the proposed
configuration.
